Episode Transcript
Why isn't more plastic actually recyclable? Why don't compostable forks actually compost? And when are we going to solve our waste problems?This episode features three scientists working to manage the planet's plastic addiction by developing smarter materials that avoid the pitfalls of 20th century plastics. We talk about the challenges of the current recycling and composting systems, philosophies of materials design, why trying to recycle some things is just "wishcycling," and why we can allow ourselves to feel a little optimism — even though the news paints a pretty bleak picture sometimes. My guests are:Brett Helms, a materials scientist at Berkeley Lab's Molecular Foundry. Helms leads a team that invented an infinitely recyclable plastic and is now working to bring it to the market.Ting Xu is a senior materials scientist and chemist at Berkeley Lab and professor at UC Berkeley. Her lab is developing non-toxic compostable plastics that stay durable when in use, but break down easily in the environment.Corinne Scown is a scientist in Berkeley Lab's Energy Technologies Area and director of Techno-economic Analysis at the Joint BioEnergy Institute. She performs techno- economic and lifecycle analyses for Brett, Ting, and other scientists, meaning that she models the inputs, outputs, prices, and environmental impact of materials so that we can understand how they will perform on an industrial scale before they actually get to the industrial scale.

In part two, Delia talks about her interests, the Molecular Foundry and its unique environment. foundry.lbl.govTranscriptSpeaker 1: Spectrum's next [inaudible] [inaudible]. [00:00:30] Welcome to spectrum the science and technology show on k a l x Berkeley, a biweekly 30 minute program bringing you interviews, featuring bay area scientists and technologists as well as a calendar of local events and news. Speaker 2: Good afternoon. My name is Brad Swift. I'm the host of today's show. Today we present part two of our two part interview with Delia Mill Iron, [00:01:00] the deputy director of the Lawrence Berkeley national lab molecular foundry, Delia mill iron. Received her undergraduate degree in chemistry from Princeton and her phd in physical chemistry from UC Berkeley. Delia leads a research group at the molecular foundry, which has spun off a startup named heliotrope technologies. Her group is a partner in the newly announced Joint Center for Energy Storage Research, a [00:01:30] multistate department of energy research hub focused on developing transformative new battery technologies. Delia's group was recently awarded a $3 million grant by the Department of Energy Advanced Research Projects, agency energy, ARPA e for her work on smart window technologies. Now the final part two of our interview. Uh, even though nano science is a relatively new pursuit, how have the tools to execute [00:02:00] your research and development? How have they advanced? Speaker 3: The tools have progressed remarkably and many would say that our ability to see material on the nataline scale and by c I mean more than just get a picture, but also to see the specifics of the chemistry, the electronic structure and so on that these advances in tools and characterization tools have [00:02:30] been the catalyst for every other development and nanoscience because it's very difficult to move quickly forward in making new materials. For example, if you can't actually see what you're making. So starting with electron microscopy, which used the fact that electrons moving very quickly, you have a wavelength far shorter than that of light and therefore they have the ability to resolve features on the nano meter and in fact on the atomic lane scale. [00:03:00] That's tremendous, right? That's an incredible enabling capability for nanoscience. But electrons are limited in the chemical information, the electronic structure information, they can probe some of this, but light is still king. Speaker 3: So spectroscopy which is using light to probe chemical bonds and composition and so forth is still king of understanding richness, rich detail about materials. So some of the most exciting events is to me [00:03:30] in the tools for nanoscience are bringing optical spectroscopy spectroscopy using light to smaller and smaller and smaller lane scales. The state of the art, if you use conventional optics, just nice, beautifully made lenses and so on is that you can use light to look at things down to about half the wavelength of light. So for visible light that means things on the order of a few hundred nanometers. If you're doing things very, very [00:04:00] well by manipulating the light further leveraging nanoscale phenomena like the plasmonics I mentioned earlier, you can now squeeze light into extremely small volumes and do optical spectroscopy down to lane scales, tens of nanometers across, so doing full rich optical characterization and materials. Speaker 3: Basically using light microscopy at 40 nanometer lanes scales is now [00:04:30] a reality and the kind of information we can get about materials, their properties and how those are related is just going to benefit tremendously from those kinds of new advances. Are there tools that you crave? Unrealized tools? Yes, sure. I love to be able to resolve rich chemical, detailed dental. The Lane scale of Adams, you know, tens of nanometers is nice, but uh, most of our nanocrystals are smaller than this. They're five [00:05:00] nanometers. There are 10 nanometers, they're not 40 or 50 nanometers. So we still haven't quite brought light in a useful way down to the dimensions of the materials that give us the most interesting properties. The other major thing many of us crave is to bring detailed characterization into three dimensions and really four dimensions. So how they're arranged in three dimensional space definitely affects their properties, but it's difficult [00:05:30] to image. Speaker 3: So microscopic tools still often look at the surface of material and so you get a two dimensional map at high resolution. It's much more difficult to get high resolution images and information in three dimensions. And then the fourth dimension is of course time. So being able to follow a structure and the flow of energy and electrons in three dimensional space as it progresses in time, pushing time resolution shorter and shorter and shorter. Can [00:06:00] we track those processes? So that we can understand how function emerges. Because function is very often dynamic in nature. It's not just a static moment in time. It's the way that chemistry and electrons and so forth progress over time. Explain the user program at the foundry. How do people get involved in that? Sure. So the, the user program provides free access to scientists from all over the world [00:06:30] who have an interest in leveraging expertise, materials, capabilities, techniques and so on that we developed at the foundry to advance their science or technology. Speaker 3: And the mode that people use, the foundry takes all different forms. Uh, one of our favorites is for scientists to send a student or postdoc or a young researcher or in fact visit themselves, for example, for a sabbatical and then actually work with us. I buy side in our lab [00:07:00] can best learn the INS and outs of working with synthesizing, measuring whatever it is, the materials and techniques of interest to them. Um, we found that this is a very powerful way to expose young scholars to the potential for interdisciplinary research as we exercise it at the foundry for this new mode of doing science where people from all different disciplines are talking every day about problems to advance a state [00:07:30] of the art. That's been very productive and I think those students and postdocs go home really changed in their outlook on how they approach science and they bring some of that perspective back to their home labs. Speaker 3: They also, by the way, bring some perspective on our safety approach back to their home labs. And we really enjoy the success stories of having companies even and also academic research lab to use our approach to safety in particular [00:08:00] nanomaterial safety but safety in general as a blueprint for setting up their own labs or for reinvigorating the safety culture and so on if their own institution. So this mode of people coming and working with us and engaging in all with a whole variety of scientists and techniques in our labs and then going back home is then tremendously effective. We also spend time, you know, shipping samples back and forth, doing some characterization on other people's materials or vice versa, shipping our materials [00:08:30] out to people who have specialized characterization, approaches that compliment what we do well and this is in the spirit, I would say of good scientific collaboration in general. But the most exciting thing by far is to bring people together and mix up their ideas and their concepts and see new things emerge. Speaker 1: [inaudible]Speaker 2: you are listening to spectrum [00:09:00] on KALX Berkeley, our guest Delia mill iron of Lawrence Berkeley national lab is talking about her work in nanoscience and nanotechnology. Speaker 1: [inaudible]Speaker 2: can you talk about the safety guidelines that are in place at the molecular foundry and in working with nanomaterials? Speaker 3: Yeah, so nanomaterials because it's a relatively new science to deliberately craft them, [00:09:30] we still don't know in many cases, the ways in which their toxicology and the risk of exposure may differ from the same material found in bulk form. And because we have this uncertainty, we owe it to ourselves and to the environment to treat them with an elevated level of care. And so the Department of Energy was actually the first agency in the u s to create specific guidelines for handling [00:10:00] nanoscale materials in laboratory environments. I was actually part of that process several years ago and that policy is updated every year and it forms the basis for what we implement on the ground in the lab terms of safety procedures. For example, we're particularly concerned about any nanomaterials that are not firmly bound within a matrix or firmly bound to a substrate because these have the potential to become airborne [00:10:30] or volatilized or something like this. Speaker 3: So that we most focus on these, which we call it quote unquote unbound engineered nanoparticles, engineered meaning deliberately created and these are always handled in enclosed ventilated environments. So for us, things like glove boxes and fume hoods and then we validate that those kinds of environments do indeed protect workers from exposure by doing low background tests for particle counts during agitated [00:11:00] procedures. So we exaggerate the potential risk. We reduce the background particle count in the lab with a portable clean room and we use a very sensitive particle counter to see if any countable particles are generated in the workspace of the actual scientists working in the lab. Um, and this helps us form systematic approaches to handling materials in ways that don't cause any exposure. Speaker 2: Is the toxicology of nanomaterials [00:11:30] a growing area of study? And what about the interaction of nanomaterials outside of the lab in the environment? Speaker 3: Yes, definitely toxicology is a growing area of study, but you raise an important point, which is even before a nano material that's out in the world can interact with a biological organism. It experiences the environment. And so the first thing that's maybe preliminary in a way, but it is now taking place at the same time as [00:12:00] to understand the fate of nano materials in the environment. So how do they move through different kinds of soil and medium because surface effects are so important. How do molecules that are just found very commonly around us adhere to the surfaces and change the properties of the nanomaterials before they ever encounter the biological organisms because that will have a big effect then on their toxicology. So the fate of Nano materials in the environment is definitely a growing [00:12:30] area of study and we've had scientists at the foundry who have collaborated with geologists for example, to understand how soil conditions and ph and so forth can affect the transport of nanomaterials that are under consideration for solar energy applications. Should they end up released, how would they respond in different kinds of soil environments and be transported or or not. In some cases they are not readily transported and that's equally important to understand Speaker 2: [inaudible] so it becomes [00:13:00] a life cycle study. Yes, materials and those things can take a long time to really get a grasp of what the impact is. How then do we gauge the extent to which nanomaterials get leveraged in the short term and monitor the longterm impacts [inaudible] Speaker 3: I think monitoring is an important point, right? It will take even longer if we're not paying attention to learn how things interact with the environment and what their fate ultimately is. So the [00:13:30] science in the lab is important, but the science as technologies begin to be released is, is equally important to track what's happening in the real world. Um, in the meantime, it's important to be thoughtful about the expected life cycle of technologies, incorporating Nana materials. So recycling programs, encapsulation recovery, assessment of likelihood of release from a completed say [00:14:00] device, like a solar cell solar cells are completely encapsulated in glass, right? So the initial thought would be, well, if this, if everything's going right, there will be no nanomaterials released. But now what if that panel breaks? What's the likelihood of that? So asking these questions upfront and taking, you know, a responsible role in the life cycle of the technology, I think is essential, particularly given the uncertainties. Speaker 4: [inaudible] [00:14:30] our guest is Delia Mil iron, the deputy director of the Lawrence Berkeley national lab molecular foundry. She was a chemist working at the Nano scale. You are listening to spectrum on KALX Berkeley. Speaker 3: How much time do you spend paying attention [00:15:00] to other areas of science and technology? As much as I possibly can. I think inspiration in science comes from broad perspective and so I am as far as I could get from being a biologist as a physical scientist, but the concepts of how biological systems work are quite intricate and inspiring though new discoveries in biomechanical [00:15:30] processes and so on can become the seed. That gives me a new idea of how to put nanocrystals together in a way that generates totally new phenomena, for example. It's also just fascinating, honestly. I mean I've always been fascinated with science, so paying attention to the uh, developments and the exploration of Mars or in astrophysics. There's a tremendous fundamental physics community at the lab and I love to listen to them talk about the [00:16:00] discoveries they're making through telescope observations of distant supernovas and these sorts of things. Speaker 3: I won't say that I can point to any direct impact that's had on my work. But I think expanding your general perspective on the way the world works at all these different length scales and timescales and so on, it forms your context as a scientist and you know, maybe as a person as well. Are there collaborations in other fields you'd like to see grow? [00:16:30] So this idea of connecting biology more deliberately are the concepts of biology more deliberately to materials research, which is my area of investigation I think is quite powerful and under exploited at this stage. It's amazing what molecular biologists now understand about the mechanisms that underlie life and how molecules [00:17:00] interact in elaborate ways to synthesize DNA, to create proteins to, you know, at completely mild conditions, fold proteins up and do catalytic activity. Things that in the engineering world, you know, have traditionally been approached by brute force, you know, thousands of degrees c and so on. And so if we can take some of these concepts from biology and see [00:17:30] how they can affect the way we approach synthetic materials to a greater extent, I think this will be a very important opportunity. Of course there are some people doing this. I don't want to suggest that that's a totally new idea, but I think that connection could be a much broader avenue than what it has been so far. Do you feel there's an element of art in what you do? Speaker 3: I think so. I definitely enjoy art, although not highly skilled. [00:18:00] My Adventures and creating sculpture, you know, clay wood and so on in my mind are in harmony with what we do on the atomic length scale in the way we try to craft nanoscale materials or madams and then craft macro scale materials from those nanoscale materials, putting them together as these building blocks and it has a sculptural aspect to it. And definitely there's beauty in the images generated when we use all these amazing [00:18:30] cutting edge techniques to visualize our structures. Is there anything that we haven't talked about that you wanted to mention? I think the other comment I'd like to make going back to the molecular foundry and I lit up when you asked me, you know, what's the foundry about? Because I really think that the research environment do, the approach to scientific research being carried out at the molecular foundry is [00:19:00] a beautiful example for the way forward for science that science can be greatly accelerated in discovery of new terrain, new subject areas entirely through this mode of intense dynamic collaboration across fields. Speaker 3: I think it was somewhat deliberate and at the same time a bit of an accident that this emerged from the creation of the molecular foundry. What the [00:19:30] founders of the foundry did that was very smart was to hire a group of very young scientists who had an approach to science where they would clearly appreciate being involved in many different projects coming from many different perspectives. This was essential to make the user program work on your scientists must be enthusiastic about collaborating with all these different scientists who have different objectives, [00:20:00] different contexts and so on, but as a consequence of hiring that group of people and putting them together in one building, what naturally happened is we all started to interact in the same way with each other and the result is that you have a coupled series of dynamic feedback loops that greatly accelerate innovation. Speaker 3: One of them being between our science and that of our users and one of them being between the scientists internal to the building and [00:20:30] the results of that experiment really in scientific structure that's represented by the foundry are just starting to appear because we're still quite a young institution and I think that the impact of this sort of model is going to felt for a long time and is going to be replicated and mapped onto other research centers. We've already seen a lot of interests in understanding the way we do our science as research centers are being set up around the [00:21:00] world and that doesn't happen very often. That's an exciting deviation from the traditional department structure, single principal investigator directed research, as brilliant as one scientists and the research group may be. It lacks that dynamism that we have. So it's sort of a high of mentality to science, if you will, and that's really interesting and gonna yield a lot of fruit, I think. Speaker 2: Delia mill iron. Thanks very much for coming on spectrum. Thank [00:21:30] you. Speaker 1: [inaudible]Speaker 2: tours of the Lawrence Berkeley national lab are available monthly. The molecular foundry is on that tour. Just sign up for a tour, go to the Lawrence Berkeley [00:22:00] national lab website, which is lbl.gov Speaker 1: [inaudible].Speaker 2: A regular feature of spectrum is to mention a few of the science and technology events happening over the next two weeks. It's quiet time of the year, not a whole lot going on, but the Lawrence Hall of Science 3d Theater has daily screenings [00:22:30] of two films, space junk, and the last reef space junk is a visually explosive journey of discovery that ways the solutions aimed at restoring our planets. Orbits Space Junk runs through January 6th, 2013 the last reef was made with new macro underwater cinematography. The last reef reveals and astonishing world rarely seen at this scale. The film presents an unprecedented vision of the intriguing creatures that participate [00:23:00] in altering the geology of our planet. The last reef runs through May 5th, 2013 the exploratorium is leaving its only home at the Palace of fine arts and moving to piers 15 and 17 on the Embarcadero in downtown San Francisco. The new exploratorium will open in the spring of 2013 this coming January 2nd is the last day to experience the exploratorium as it is currently installed at the Palace of fine arts opened in 1969 [00:23:30] the exploratorium has evolved in this unwieldy space for 43 years. Catch one final glimpse. Wednesday, January 2nd, 2013 check the exploratorium website for special events on that final day. The website is exploratorium.edu Speaker 1: [inaudible]Speaker 2: for the new segment. I want to do something a little different. As the year [00:24:00] draws to a close. I want to offer a short update on salient, national and commercial space launch ventures. Starting with the u s NASA reports that the Orien spacecraft is coming together for its 2014 test flight. Orianna is a new capsule that will take human exploration beyond earth orbit for the first time in 40 years. The first unmanned flight test of Orien will be launched a top a Delta for rocket from Cape Kennedy. The capsule [00:24:30] will be flown 3,600 miles above the earth and then return to the earth at 5,000 miles per hour for re-entry. The reentry will test the heat yields the landing at sea and the u s navy's recovery of the capsule. The longer term plans are to test the same capsule launched on NASA's next heavy lift rocket dubbed the space launch system. Speaker 2: SLS in 2017 SLS will launch NASA's Orient Spacecraft and other [00:25:00] payloads beyond lower earth orbit providing an entirely new capability for human exploration. Space x, the U S Commercial Space Company has completed the first of a contracted 12 supply missions to the international space station. Space X is also working with NASA to develop and test the dragon capsule to allow it to transport humans to and from the international space station. On that point. In August, NASA announced the winners [00:25:30] of the commercial crew integrated capability funded space act agreements. This program is designed to supply NASA with a domestic commercial capability to transport humans into low earth orbit, specifically to the International Space Station and back. The winning companies are Boeing with a $460 million contract space x at $440 million and Sierra Nevada corporation receiving 212.5 million. [00:26:00] In June, 2012 China launched this shungite in nine spacecraft, a top a long march rocket. The spacecraft carried three crew members on a mission to dock with the Chinese space station. The mission was successful and is widely regarded as a major accomplishment for the Chinese based program. The mission will be repeated. In 2013 India marked its 101st space mission. October 1st of 2012 [00:26:30] with the launch of its heaviest communications. Satellite Gee sat 10 from French Guyana. The Indian Space Research Organization has 10 mission scheduled for 2013 the tentative capper is a plan in November, 2013 Mars orbiter to be done without any international help. Speaker 2: The Russian space program continues to struggle after a series of embarrassing failures in spacecraft launches and flight operations that have cast [00:27:00] the future of the entire program. In doubt, observers fear that the rise of cheaper, more modern and reliable commercial space companies in the United States will peel off Russia's spaced services customers who currently infuse $1 billion annually into the Russian space. Industry. Insiders say consolidation, innovation, and modernization are required to save the industry. Leadership and funding for such a revival program are missing. At this point. The European space [00:27:30] agency successfully launched seven Ariane five rockets from their space port in French, Guyana during 2012 the Arianne five has had 53 successful launches in a row since December, 2002 Speaker 5: [inaudible]Speaker 2: an interesting space, junk liability arose for the European Space Agency. When a large lower earth orbit satellite nearing the end of its fuel supply suddenly went silent. The satellite is now stuck in a prime orbit corridor [00:28:00] that will take 100 years to degrade and fall to earth during the next 100 years. This satellite may collide with other satellites. If it does, the European Space Agency is thought to be liable for the damage done. No removal method of space. Junk currently exists. That's it. Happy New Year.

Can [00:06:00] we track those processes? So that we can understand how function emerges. Because function is very often dynamic in nature. It's not just a static moment in time. It's the way that chemistry and electrons and so forth progress over time. Explain the user program at the foundry. How do people get involved in that? Sure. So the, the user program provides free access to scientists from all over the world [00:06:30] who have an interest in leveraging expertise, materials, capabilities, techniques and so on that we developed at the foundry to advance their science or technology. Speaker 3: And the mode that people use, the foundry takes all different forms. Uh, one of our favorites is for scientists to send a student or postdoc or a young researcher or in fact visit themselves, for example, for a sabbatical and then actually work with us. I buy side in our lab [00:07:00] can best learn the INS and outs of working with synthesizing, measuring whatever it is, the materials and techniques of interest to them. Um, we found that this is a very powerful way to expose young scholars to the potential for interdisciplinary research as we exercise it at the foundry for this new mode of doing science where people from all different disciplines are talking every day about problems to advance a state [00:07:30] of the art. That's been very productive and I think those students and postdocs go home really changed in their outlook on how they approach science and they bring some of that perspective back to their home labs. Speaker 3: They also, by the way, bring some perspective on our safety approach back to their home labs. And we really enjoy the success stories of having companies even and also academic research lab to use our approach to safety in particular [00:08:00] nanomaterial safety but safety in general as a blueprint for setting up their own labs or for reinvigorating the safety culture and so on if their own institution. So this mode of people coming and working with us and engaging in all with a whole variety of scientists and techniques in our labs and then going back home is then tremendously effective. We also spend time, you know, shipping samples back and forth, doing some characterization on other people's materials or vice versa, shipping our materials [00:08:30] out to people who have specialized characterization, approaches that compliment what we do well and this is in the spirit, I would say of good scientific collaboration in general. But the most exciting thing by far is to bring people together and mix up their ideas and their concepts and see new things emerge. Speaker 1: [inaudible]Speaker 2: you are listening to spectrum [00:09:00] on KALX Berkeley, our guest Delia mill iron of Lawrence Berkeley national lab is talking about her work in nanoscience and nanotechnology. Speaker 1: [inaudible]Speaker 2: can you talk about the safety guidelines that are in place at the molecular foundry and in working with nanomaterials? Speaker 3: Yeah, so nanomaterials because it's a relatively new science to deliberately craft them, [00:09:30] we still don't know in many cases, the ways in which their toxicology and the risk of exposure may differ from the same material found in bulk form. And because we have this uncertainty, we owe it to ourselves and to the environment to treat them with an elevated level of care. And so the Department of Energy was actually the first agency in the u s to create specific guidelines for handling [00:10:00] nanoscale materials in laboratory environments. I was actually part of that process several years ago and that policy is updated every year and it forms the basis for what we implement on the ground in the lab terms of safety procedures. For example, we're particularly concerned about any nanomaterials that are not firmly bound within a matrix or firmly bound to a substrate because these have the potential to become airborne [00:10:30] or volatilized or something like this. Speaker 3: So that we most focus on these, which we call it quote unquote unbound engineered nanoparticles, engineered meaning deliberately created and these are always handled in enclosed ventilated environments. So for us, things like glove boxes and fume hoods and then we validate that those kinds of environments do indeed protect workers from exposure by doing low background tests for particle counts during agitated [00:11:00] procedures. So we exaggerate the potential risk. We reduce the background particle count in the lab with a portable clean room and we use a very sensitive particle counter to see if any countable particles are generated in the workspace of the actual scientists working in the lab. Um, and this helps us form systematic approaches to handling materials in ways that don't cause any exposure. Speaker 2: Is the toxicology of nanomaterials [00:11:30] a growing area of study? And what about the interaction of nanomaterials outside of the lab in the environment? Speaker 3: Yes, definitely toxicology is a growing area of study, but you raise an important point, which is even before a nano material that's out in the world can interact with a biological organism. It experiences the environment. And so the first thing that's maybe preliminary in a way, but it is now taking place at the same time as [00:12:00] to understand the fate of nano materials in the environment. So how do they move through different kinds of soil and medium because surface effects are so important. How do molecules that are just found very commonly around us adhere to the surfaces and change the properties of the nanomaterials before they ever encounter the biological organisms because that will have a big effect then on their toxicology. So the fate of Nano materials in the environment is definitely a growing [00:12:30] area of study and we've had scientists at the foundry who have collaborated with geologists for example, to understand how soil conditions and ph and so forth can affect the transport of nanomaterials that are under consideration for solar energy applications. Should they end up released, how would they respond in different kinds of soil environments and be transported or or not. In some cases they are not readily transported and that's equally important to understand Speaker 2: [inaudible] so it becomes [00:13:00] a life cycle study. Yes, materials and those things can take a long time to really get a grasp of what the impact is. How then do we gauge the extent to which nanomaterials get leveraged in the short term and monitor the longterm impacts [inaudible] Speaker 3: I think monitoring is an important point, right? It will take even longer if we're not paying attention to learn how things interact with the environment and what their fate ultimately is. So the [00:13:30] science in the lab is important, but the science as technologies begin to be released is, is equally important to track what's happening in the real world. Um, in the meantime, it's important to be thoughtful about the expected life cycle of technologies, incorporating Nana materials. So recycling programs, encapsulation recovery, assessment of likelihood of release from a completed say [00:14:00] device, like a solar cell solar cells are completely encapsulated in glass, right? So the initial thought would be, well, if this, if everything's going right, there will be no nanomaterials released. But now what if that panel breaks? What's the likelihood of that? So asking these questions upfront and taking, you know, a responsible role in the life cycle of the technology, I think is essential, particularly given the uncertainties. Speaker 4: [inaudible] [00:14:30] our guest is Delia Mil iron, the deputy director of the Lawrence Berkeley national lab molecular foundry. She was a chemist working at the Nano scale. You are listening to spectrum on KALX Berkeley. Speaker 3: How much time do you spend paying attention [00:15:00] to other areas of science and technology? As much as I possibly can. I think inspiration in science comes from broad perspective and so I am as far as I could get from being a biologist as a physical scientist, but the concepts of how biological systems work are quite intricate and inspiring though new discoveries in biomechanical [00:15:30] processes and so on can become the seed. That gives me a new idea of how to put nanocrystals together in a way that generates totally new phenomena, for example. It's also just fascinating, honestly. I mean I've always been fascinated with science, so paying attention to the uh, developments and the exploration of Mars or in astrophysics. There's a tremendous fundamental physics community at the lab and I love to listen to them talk about the [00:16:00] discoveries they're making through telescope observations of distant supernovas and these sorts of things. Speaker 3: I won't say that I can point to any direct impact that's had on my work. But I think expanding your general perspective on the way the world works at all these different length scales and timescales and so on, it forms your context as a scientist and you know, maybe as a person as well. Are there collaborations in other fields you'd like to see grow? [00:16:30] So this idea of connecting biology more deliberately are the concepts of biology more deliberately to materials research, which is my area of investigation I think is quite powerful and under exploited at this stage. It's amazing what molecular biologists now understand about the mechanisms that underlie life and how molecules [00:17:00] interact in elaborate ways to synthesize DNA, to create proteins to, you know, at completely mild conditions, fold proteins up and do catalytic activity. Things that in the engineering world, you know, have traditionally been approached by brute force, you know, thousands of degrees c and so on. And so if we can take some of these concepts from biology and see [00:17:30] how they can affect the way we approach synthetic materials to a greater extent, I think this will be a very important opportunity. Of course there are some people doing this. I don't want to suggest that that's a totally new idea, but I think that connection could be a much broader avenue than what it has been so far. Do you feel there's an element of art in what you do? Speaker 3: I think so. I definitely enjoy art, although not highly skilled. [00:18:00] My Adventures and creating sculpture, you know, clay wood and so on in my mind are in harmony with what we do on the atomic length scale in the way we try to craft nanoscale materials or madams and then craft macro scale materials from those nanoscale materials, putting them together as these building blocks and it has a sculptural aspect to it. And definitely there's beauty in the images generated when we use all these amazing [00:18:30] cutting edge techniques to visualize our structures. Is there anything that we haven't talked about that you wanted to mention? I think the other comment I'd like to make going back to the molecular foundry and I lit up when you asked me, you know, what's the foundry about? Because I really think that the research environment do, the approach to scientific research being carried out at the molecular foundry is [00:19:00] a beautiful example for the way forward for science that science can be greatly accelerated in discovery of new terrain, new subject areas entirely through this mode of intense dynamic collaboration across fields. Speaker 3: I think it was somewhat deliberate and at the same time a bit of an accident that this emerged from the creation of the molecular foundry. What the [00:19:30] founders of the foundry did that was very smart was to hire a group of very young scientists who had an approach to science where they would clearly appreciate being involved in many different projects coming from many different perspectives. This was essential to make the user program work on your scientists must be enthusiastic about collaborating with all these different scientists who have different objectives, [00:20:00] different contexts and so on, but as a consequence of hiring that group of people and putting them together in one building, what naturally happened is we all started to interact in the same way with each other and the result is that you have a coupled series of dynamic feedback loops that greatly accelerate innovation. Speaker 3: One of them being between our science and that of our users and one of them being between the scientists internal to the building and [00:20:30] the results of that experiment really in scientific structure that's represented by the foundry are just starting to appear because we're still quite a young institution and I think that the impact of this sort of model is going to felt for a long time and is going to be replicated and mapped onto other research centers. We've already seen a lot of interests in understanding the way we do our science as research centers are being set up around the [00:21:00] world and that doesn't happen very often. That's an exciting deviation from the traditional department structure, single principal investigator directed research, as brilliant as one scientists and the research group may be. It lacks that dynamism that we have. So it's sort of a high of mentality to science, if you will, and that's really interesting and gonna yield a lot of fruit, I think. Speaker 2: Delia mill iron. Thanks very much for coming on spectrum. Thank [00:21:30] you. Speaker 1: [inaudible]Speaker 2: tours of the Lawrence Berkeley national lab are available monthly. The molecular foundry is on that tour. Just sign up for a tour, go to the Lawrence Berkeley [00:22:00] national lab website, which is lbl.gov Speaker 1: [inaudible].Speaker 2: A regular feature of spectrum is to mention a few of the science and technology events happening over the next two weeks. It's quiet time of the year, not a whole lot going on, but the Lawrence Hall of Science 3d Theater has daily screenings [00:22:30] of two films, space junk, and the last reef space junk is a visually explosive journey of discovery that ways the solutions aimed at restoring our planets. Orbits Space Junk runs through January 6th, 2013 the last reef was made with new macro underwater cinematography. The last reef reveals and astonishing world rarely seen at this scale. The film presents an unprecedented vision of the intriguing creatures that participate [00:23:00] in altering the geology of our planet. The last reef runs through May 5th, 2013 the exploratorium is leaving its only home at the Palace of fine arts and moving to piers 15 and 17 on the Embarcadero in downtown San Francisco. The new exploratorium will open in the spring of 2013 this coming January 2nd is the last day to experience the exploratorium as it is currently installed at the Palace of fine arts opened in 1969 [00:23:30] the exploratorium has evolved in this unwieldy space for 43 years. Catch one final glimpse. Wednesday, January 2nd, 2013 check the exploratorium website for special events on that final day. The website is exploratorium.edu Speaker 1: [inaudible]Speaker 2: for the new segment. I want to do something a little different. As the year [00:24:00] draws to a close. I want to offer a short update on salient, national and commercial space launch ventures. Starting with the u s NASA reports that the Orien spacecraft is coming together for its 2014 test flight. Orianna is a new capsule that will take human exploration beyond earth orbit for the first time in 40 years. The first unmanned flight test of Orien will be launched a top a Delta for rocket from Cape Kennedy. The capsule [00:24:30] will be flown 3,600 miles above the earth and then return to the earth at 5,000 miles per hour for re-entry. The reentry will test the heat yields the landing at sea and the u s navy's recovery of the capsule. The longer term plans are to test the same capsule launched on NASA's next heavy lift rocket dubbed the space launch system. Speaker 2: SLS in 2017 SLS will launch NASA's Orient Spacecraft and other [00:25:00] payloads beyond lower earth orbit providing an entirely new capability for human exploration. Space x, the U S Commercial Space Company has completed the first of a contracted 12 supply missions to the international space station. Space X is also working with NASA to develop and test the dragon capsule to allow it to transport humans to and from the international space station. On that point. In August, NASA announced the winners [00:25:30] of the commercial crew integrated capability funded space act agreements. This program is designed to supply NASA with a domestic commercial capability to transport humans into low earth orbit, specifically to the International Space Station and back. The winning companies are Boeing with a $460 million contract space x at $440 million and Sierra Nevada corporation receiving 212.5 million. [00:26:00] In June, 2012 China launched this shungite in nine spacecraft, a top a long march rocket. The spacecraft carried three crew members on a mission to dock with the Chinese space station. The mission was successful and is widely regarded as a major accomplishment for the Chinese based program. The mission will be repeated. In 2013 India marked its 101st space mission. October 1st of 2012 [00:26:30] with the launch of its heaviest communications. Satellite Gee sat 10 from French Guyana. The Indian Space Research Organization has 10 mission scheduled for 2013 the tentative capper is a plan in November, 2013 Mars orbiter to be done without any international help. Speaker 2: The Russian space program continues to struggle after a series of embarrassing failures in spacecraft launches and flight operations that have cast [00:27:00] the future of the entire program. In doubt, observers fear that the rise of cheaper, more modern and reliable commercial space companies in the United States will peel off Russia's spaced services customers who currently infuse $1 billion annually into the Russian space. Industry. Insiders say consolidation, innovation, and modernization are required to save the industry. Leadership and funding for such a revival program are missing. At this point. The European space [00:27:30] agency successfully launched seven Ariane five rockets from their space port in French, Guyana during 2012 the Arianne five has had 53 successful launches in a row since December, 2002 Speaker 5: [inaudible]Speaker 2: an interesting space, junk liability arose for the European Space Agency. When a large lower earth orbit satellite nearing the end of its fuel supply suddenly went silent. The satellite is now stuck in a prime orbit corridor [00:28:00] that will take 100 years to degrade and fall to earth during the next 100 years. This satellite may collide with other satellites. If it does, the European Space Agency is thought to be liable for the damage done. No removal method of space. Junk currently exists. That's it. Happy New Year.

Delia mill iron. Welcome to spectrum. Speaker 5: Thank you.Speaker 4: I suspect that most of our listeners have heard of nanoscience but don't have a lot of perspective on the detail. Would you explain what makes nanoscience and nanotechnology unique? Speaker 5: Sure, [00:02:00] so nano science is about investigating how the properties of matter change sometimes quite dramatically when we structure them on the nanometers scale, which is really the molecular scale. So in a sense it's quite related to chemistry, but it's about materials and matter and how their behavior is very different than what you'd expect from macroscopic pieces of material. Would you like some examples? [00:02:30] Sure. An example would be great. Okay. A classic example is to look at the optical properties or just the visible appearance of gold and everyone knows, of course, when gold is macroscopic, it's shiny and it's yellowish and we're very used to that form of gold. When you make gold in the form of nanoparticles, the things that are, let's say between five and 50 nanometers across [00:03:00] or containing a few thousand atoms per particle, then the gold no longer looks either yellow or shiny. In fact, you can make stable dispersion or solution of gold at that scale in water. And it appears translucent and red in color. And this effect of Nano scaling and gold has been used to color artistic objects for centuries, but we've only recently become to systematically [00:03:30] understand the science of how these sorts of properties can change so dramatically when we make materials in the nanoscale. Speaker 4: So the actual doing of it has been done for a long time, but the understanding is what's more recent and then the ability to recreate Speaker 5: and the ability to control and deliberately manipulate. Yes. So there are plenty of instances of incidental or almost accidental creation of nanoscale materials and [00:04:00] utilization of these nanoscale effects on properties. But the science of it is about systematically correlating the structure and composition and materials to their properties. And then the nanotechnology or the engineering of of nanoscale materials is about deliberately controlling those properties to create new functional things, objects, devices and so on that we can use for useful things all around us. Speaker 4: And what are some of the common things [00:04:30] that we find nano technology in in our daily lives? Speaker 5: As with any new technology. The first applications are fairly pedestrian in some sense and don't require the most exquisite control over the materials. So one that's quite common is to use metal oxide nanocrystals. Typically things like zinc oxide or titanium oxide in sunblock. These materials absorb UV radiation to [00:05:00] protect our skin from damage from UV. But because they're at the nano scale, instead of looking white, it can be clear. And so it's just that ugly, much more pleasing to put on some block that then appears clear, but still does the job of blocking UV radiation. So this doesn't require a very fine control over the details of the structure or the size of the material. It's only important that the scale of the oxide particles be well below the wavelength [00:05:30] of light, and that's what makes it clear. So it's a very simple use, but nonetheless, very practical and helpful. Speaker 4: What are you finding are the challenges of working with nanoscale material? Speaker 5: It's all about taking that control to the next level. Chemists have learned for a long time how to manipulate atoms and create bonds and put them together into small molecules. Now we're working with structures of [00:06:00] a somewhat larger length scale and wanting to control different aspects of the composition and structure. So there are no ready solutions for deliberately arranging the atoms into let's say a five nanometer crystal with precision, um, in order to generate the properties that you'd like or again, just understand them frankly. So both the creation of materials with precise control and detailed understanding of what their structure is are still very [00:06:30] big challenges. Of course conventional microscopy methods don't extend very well to these small length scales. So there's a need for new characterization approaches. And then as I said, the chemical methods for making molecules and small molecular systems likewise don't necessarily translate to the slightly bigger scale that is nanometer length scale of these materials. Speaker 5: So we need a innovations on all sides, making new materials, new ways to look at them and characterize [00:07:00] them. And then finally the third piece is the theory that helps understand their properties and predict new properties. Again, it's sort of an awkward in between lanes scale where atomic detail matters, but larger scale aspects of how the materials come together matters as well. And that's very difficult to approach with computational methods, so we're seeing the frontier of nanoscience is pushing scientists from all different disciplines to advance their tools and their techniques [00:07:30] in order to really take advantage of what can be done at that landscape. Speaker 4: Okay. Speaker 6: Delia mill iron is our guest. She is the deputy director of the Lawrence Berkeley National Laboratory molecular foundry. She is a chemist working at the nanoscale. You are listening to spectrum on k a l x Berkeley. Speaker 4: You've talked about the meter. Yes. Is that a new form of measurement and how does it relate to anything [00:08:00] else? How do we reflect on an nanometre? Sure, Speaker 5: so it's not a new measure. It's simply a meter times 10 to the minus ninth that's what what Nano means and a more conventional measure on that lane scale might be an Angstrom, which is a traditional measure. It's one order of magnitude smaller than an animator, but to put it in more practical terms, I like to think of the Nano crystals that I work with, for example, which are about five nanometers across, [00:08:30] are about a million times smaller than an ant. So that for me gives me a sort of practical reference point as a chemist. It also makes sense to me to think of a five nanometer crystal as containing about a thousand atoms, but atoms are not necessarily a easy to understand lane skill for everybody. So the the ant is maybe a more common reference point, what natural materials have been created and what about them makes them [00:09:00] more promising than another depending on the realm of properties that you examine. Speaker 5: Promising has all sorts of different meanings, right? So things like semiconductor nano wires or perhaps graphene or carbon nanotubes may be considered promising for new electronic materials because the transport of electrons through these structures can proceed quite unimpeded and move very [00:09:30] readily so that we could have fast electronics or very conductive transparent thin films to replace the things we use today in our flat panel displays and so on. Other nano materials are very promising for diagnostics of different kinds of diseases or even for therapy of different kinds of health issues. So there are biological probes being developed that can be directed into specific areas [00:10:00] of your body. For example, where a tumor site is located using a nanoscale magnet and then they also carry a payload of drugs that can then be released specifically at that site. So you could have targeted therapies. So these sort of multifunctional nano constructs are very interesting. Speaker 5: I would say promising in the long run for for new targeted therapies, I have many fewer side effects than these broad spectrum drugs that we commonly use today. In terms of coming up [00:10:30] with new nanomaterials, is it as often the case that you are trying to create something for a specific purpose or that you accidentally find something that has a characteristic that can be applied pretty widely or to a specific use? I think that much of Nano materials research is motivated by the investigation and discovery of new phenomenon. And I distinguish that from targeted application [00:11:00] focused development because it's often unclear what a new material or it's phenomenological characteristics will actually be useful for. In my lab. Uh, we do tend to think of practical connections, but then the ones that we ultimately realize could be very different from the one that motivated us at the outset of the project. So I think as a scientist it's important to be attuned [00:11:30] for surprising opportunities to apply materials in ways you didn't anticipate. And so you have to be aware of the needs that are out there, the big needs in society, basically paying attention for how the phenomena you're discovering might map onto these societal needs. You probably as a scientist, not going to able to take Speaker 5: a new discovery all the way through to a practical application. But if you don't at [00:12:00] least identify those connections, it will be difficult for engineers and industry to take your discoveries and turn them into practical applications. So there's a role on both sides to make that connection. Speaker 4: [inaudible] you are the deputy director of the molecular foundry at Lawrence Berkeley National Lab. Tell us about the foundry and the work going on there. Speaker 5: So the molecular foundry is a very special place. It's one of five department of energy funded [00:12:30] nanoscale science research centers, which are located around the country. And we have the mission of pushing the forefront of nanoscience broadly defined, so nanoscience in all different aspects while at the same time acting as a user facility to help others in the scientific community, be they academic researchers, industry, others at national labs move the science in their areas forward by leveraging the tools of nanoscience. [00:13:00] So it in effect, it becomes this amazing hub of activity and nanoscience where people from really all around the world are coming to us to leverage capabilities that we are continuously advancing and developing in different kinds of nanoscience be it inorganic nanocrystals, which is my focus theoretical methods for treating nanoscience completely out of this world. In my mind, I'm spectroscopic techniques [00:13:30] for looking at nanostructures.Speaker 5: All these things are being developed at the foundry, at the absolute bleeding edge of nanoscience, and these can have impact in all different areas. And so our users come, they work with us, they learn these state of the art techniques, generate new materials that they can take home with them to their own laboratories, integrate into their materials and processes and devices and so on or do their a specialized characterization on and the amount of science that results by [00:14:00] that multiplication and leveraging is really very exciting to watch. Oh, it's a hub. It's an intersection of ideas in one place of problem, motivations from different perspectives and then it branches right on back out to impact science and in all different ways. Speaker 4: What sort of a funding horizon are you on? Speaker 5: Uh, so we have very stable funding from the Department of Energy. These centers are quite new. They were only established [00:14:30] over the last 10 years. The foundry has been in full operations for about six years and they are very much the flagship capabilities of the office of science within the Department of Energy and will be for quite some time to come. So they're making a very stable and continued investment in this area and continue to see the value and opportunity for really in the end, American economy, taxpayers and industrial [00:15:00] innovation that's generated by all of this scientific activity. Speaker 2: [inaudible]Speaker 4: you were listening to spectrum on k a l x Berkeley, Delia mill, iron of Lawrence Berkeley national lab is talking about her work in nanoscience and nanotechnology. Speaker 2: [inaudible]Speaker 4: what's the focus of your research? Speaker 5: So my research involves the [00:15:30] innovation of Inorganic nanocrystals, which are a few nanometers diameter crystal and arrangements of atoms. And they're using these as building blocks to construct materials. So we put them together with each other and two, for example, porous architectures, or you put them together with polymers or we put them together, uh, with glassy components to construct macroscopic materials often than films. And we're interested [00:16:00] in these primarily for their electrochemical functions. So electric chemical devices are useful for things like batteries, supercapacitors a storing energy also for converting energy. And in our case, we've most recently been focused on electrochromic window applications. So these are function like batteries, but instead of storing charge, they have the effect of changing the tint on a window dynamically as a function [00:16:30] of voltage. But everything starts with the nanocrystals and new ways to put them together with other components to construct materials. Speaker 4: And is the crystal material something unusual or is it real commonplace? Speaker 5: It varies actually. Most of the materials that we craft into nanocrystals are well known and have been studied for a long time in their bulk form. So just as in the example of gold being very different in both and obviously useful for [00:17:00] all sorts of things like currency now having very different function on the Nano scale. We work with materials that maybe are not quite as common places goal, but nonetheless fairly common. So one material we've been working with a lot lately is called indium tin oxide. And whether you know it or not, you probably use it every day. It's the material that provides conductivity in flat panel displays, touch screens, all of these sorts of things. And so in it's normal thin [00:17:30] film form, it's obviously very well established and used around the world for all different applications. It was only synthesized in a well controlled way as Netto crystals in the last few years. Speaker 5: And in the Neto crystal form, it has all of these wonderful properties relating to electric chromic windows. And beyond that it has, I guess I should say more fundamentally, the phenomenology underlying those windows applications is that this [00:18:00] material is plasmonic, which means that it can effectively condense a near infrared light to a very small scale, can amplify the electric field from the light, basically manipulate light in a new way. And people have been doing this with metals like gold as one example. Silver is another for a while, and a whole new field of plasmonics has emerged. Um, now with Ito on the nanoscale, we're bringing [00:18:30] plasmonics into the infrared region of the spectrum, which is going to give us whole news opportunities for manipulation of light of that sword, channeling light and so on. So the, as I was saying earlier, the phenomenology is where we spend the most time and discovery of these plasmonic characteristics of Ito is going to lead to many, many applications. The one we've been focusing on is this electric chromic window idea. Speaker 4: Oh, is this one of the real opportunities [00:19:00] within nano science that when you take a material to the Nano scale, you get all this new behavior [inaudible] Speaker 5: that's the fundamental concept underlying the investigation of nanoscale materials. And so the NNI, the national nanoscience initiative or national nanotechnology initiative, which was started, you know, over a decade ago now had as its founding principle, basically that idea that we would investigate the properties that emerge [00:19:30] when materials are made on the nanoscale that are very distinct from what we see on the macro scale. And from this, uh, we would have a whole new playbook for creating functional materials and devices. Speaker 4: There's been talk about the idea of transparent failure being a good thing in science. So you can learn from what goes wrong. Speaker 5: Yeah, science is full of failure. Most things don't work, especially when you first try them. [00:20:00] So I like to say that in order to be a scientist, you have to be unrelentingly optimistic because you're great idea that you're incredibly excited about, probably won't work or at least it won't work initially. And then you have to try again and try again and try again. And often it won't work even after you've tried again many, many times and you still have to have the same passion for your next great idea that you wake up the next morning [00:20:30] and you're excited to go try something new. That belief in possibility I think is fundamental to science, but at the same point. Yeah, I think you're right. The failures are not merely something to be discarded along the way to, and they do teach us a lot and frankly they suggest the next great idea more often than not. Speaker 5: So we have in mind something we're trying to do and a complete failure to [00:21:00] accomplish that. Whether it's a bond we're trying to make or a way we're trying to control a shape of a material or to create a specific optical property we get something we didn't expect and that should and when science is functioning well does cause you to stop and think about why that's happening. In fact, maybe the challenge, some of the challenge in doing science is not becoming too distracted by all of the [00:21:30] possibilities that emerge. When you do that. It's a mistake of course to be too single minded and focused on an end goal too early because you'll, you'll miss really all the new phenomenon, the things that you least expected are often the most important and innovative, so you have to pay attention to these things and perhaps redefine them as not being failures but rather being a new success or a new seed of a success that can take you in a new direction. Speaker 5: That said, there probably are things that [00:22:00] even in that from that perspective can be viewed as a negative result or a failure and there's an important role. I mean the scientific literature is, is full of every scholarly article has to include a transparent reporting of the conditions that led to what's being defined as success or specific results and a recording of what happens elsewise basically because that allows you to understand much more [00:22:30] deeply where that successful result emerges if you understand the conditions that lead to failure and different types of failure. So definitely for understanding sake, this is essential. Speaker 3: This is the end part. One of our interview with Delia [inaudible] finale, part two will air December 28th at noon. Don't miss it.

Remember that's beginning on December 26th [inaudible] Speaker 7: with two news stories. Here is Rick Karnofsky and Lisa kind of itch. Nature News reported on December 11th Speaker 1: that the u s national ignition facility or Nif at Lawrence Livermore national laboratory is changing directions. Nip uses a 192 ultraviolet laser beams that interact with the gold capsule, creating x-rays. These x-rays [00:27:00] crush a two millimeter target pellet of deuterium and tritium causing fusion. Nif has not yet achieved ignition where it may deliver more energy than it consumes I triple e spectrum criticized the project for being $5 billion over budget and years behind. Schedule in the revised plans [inaudible] scale back to focus on ignition and would devote three years for deciding whether it would be possible. It would increase focus on research, a fusion for the nuclear weapons [00:27:30] stockpile stewardship program and basic science. It would also devote resources to other ignition concepts. Namely polar direct drive on Omega at the University of Rochester and magnetically driven implosions on the San Diego z machine. The Journal. Nature reports that rows matter a natural plant die once price throughout the old world to make fiery red textiles has found a second life as the basis for a new green [00:28:00] battery chemist from the City College of New York teamed with researchers from Rice University and the U S army research lab to develop a nontoxic and sustainable lithium ion battery powered by Perper in a dye extracted from the roots of the matter plant 3,500 years ago. Speaker 1: Civilizations in Asia and the Middle East first boiled matter roots to color fabrics in vivid oranges, reds, and pinks. In its latest incarnation, [00:28:30] the climbing herb could lay the foundation for an ecofriendly alternative to traditional lithium ion batteries. These batteries charge everything from your mobile phone to electric vehicles, but carry with them risks to the environment during production, recycling and disposal. They also pumped 72 kilograms of carbon dioxide into the atmosphere for every kilowatt hour of energy in a lithium ion battery. These grim facts have fed a surging demand to develop green batteries [00:29:00] growing matter or other biomass crops to make batteries which soak up carbon dioxide and eliminate the disposal problem.

Delios group was recently awarded a $3 million grant [00:01:30] by the Department of Energy Advanced Research projects, agency dash energy by e for her work on smart window technologies onto the interview. Delia mill iron. Welcome to spectrum. Speaker 5: Thank you.Speaker 4: I suspect that most of our listeners have heard of nanoscience but don't have a lot of perspective on the detail. Would you explain what makes nanoscience and nanotechnology unique? Speaker 5: Sure, [00:02:00] so nano science is about investigating how the properties of matter change sometimes quite dramatically when we structure them on the nanometers scale, which is really the molecular scale. So in a sense it's quite related to chemistry, but it's about materials and matter and how their behavior is very different than what you'd expect from macroscopic pieces of material. Would you like some examples? [00:02:30] Sure. An example would be great. Okay. A classic example is to look at the optical properties or just the visible appearance of gold and everyone knows, of course, when gold is macroscopic, it's shiny and it's yellowish and we're very used to that form of gold. When you make gold in the form of nanoparticles, the things that are, let's say between five and 50 nanometers across [00:03:00] or containing a few thousand atoms per particle, then the gold no longer looks either yellow or shiny. In fact, you can make stable dispersion or solution of gold at that scale in water. And it appears translucent and red in color. And this effect of Nano scaling and gold has been used to color artistic objects for centuries, but we've only recently become to systematically [00:03:30] understand the science of how these sorts of properties can change so dramatically when we make materials in the nanoscale. Speaker 4: So the actual doing of it has been done for a long time, but the understanding is what's more recent and then the ability to recreate Speaker 5: and the ability to control and deliberately manipulate. Yes. So there are plenty of instances of incidental or almost accidental creation of nanoscale materials and [00:04:00] utilization of these nanoscale effects on properties. But the science of it is about systematically correlating the structure and composition and materials to their properties. And then the nanotechnology or the engineering of of nanoscale materials is about deliberately controlling those properties to create new functional things, objects, devices and so on that we can use for useful things all around us. Speaker 4: And what are some of the common things [00:04:30] that we find nano technology in in our daily lives? Speaker 5: As with any new technology. The first applications are fairly pedestrian in some sense and don't require the most exquisite control over the materials. So one that's quite common is to use metal oxide nanocrystals. Typically things like zinc oxide or titanium oxide in sunblock. These materials absorb UV radiation to [00:05:00] protect our skin from damage from UV. But because they're at the nano scale, instead of looking white, it can be clear. And so it's just that ugly, much more pleasing to put on some block that then appears clear, but still does the job of blocking UV radiation. So this doesn't require a very fine control over the details of the structure or the size of the material. It's only important that the scale of the oxide particles be well below the wavelength [00:05:30] of light, and that's what makes it clear. So it's a very simple use, but nonetheless, very practical and helpful. Speaker 4: What are you finding are the challenges of working with nanoscale material? Speaker 5: It's all about taking that control to the next level. Chemists have learned for a long time how to manipulate atoms and create bonds and put them together into small molecules. Now we're working with structures of [00:06:00] a somewhat larger length scale and wanting to control different aspects of the composition and structure. So there are no ready solutions for deliberately arranging the atoms into let's say a five nanometer crystal with precision, um, in order to generate the properties that you'd like or again, just understand them frankly. So both the creation of materials with precise control and detailed understanding of what their structure is are still very [00:06:30] big challenges. Of course conventional microscopy methods don't extend very well to these small length scales. So there's a need for new characterization approaches. And then as I said, the chemical methods for making molecules and small molecular systems likewise don't necessarily translate to the slightly bigger scale that is nanometer length scale of these materials. Speaker 5: So we need a innovations on all sides, making new materials, new ways to look at them and characterize [00:07:00] them. And then finally the third piece is the theory that helps understand their properties and predict new properties. Again, it's sort of an awkward in between lanes scale where atomic detail matters, but larger scale aspects of how the materials come together matters as well. And that's very difficult to approach with computational methods, so we're seeing the frontier of nanoscience is pushing scientists from all different disciplines to advance their tools and their techniques [00:07:30] in order to really take advantage of what can be done at that landscape. Speaker 4: Okay. Speaker 6: Delia mill iron is our guest. She is the deputy director of the Lawrence Berkeley National Laboratory molecular foundry. She is a chemist working at the nanoscale. You are listening to spectrum on k a l x Berkeley. Speaker 4: You've talked about the meter. Yes. Is that a new form of measurement and how does it relate to anything [00:08:00] else? How do we reflect on an nanometre? Sure, Speaker 5: so it's not a new measure. It's simply a meter times 10 to the minus ninth that's what what Nano means and a more conventional measure on that lane scale might be an Angstrom, which is a traditional measure. It's one order of magnitude smaller than an animator, but to put it in more practical terms, I like to think of the Nano crystals that I work with, for example, which are about five nanometers across, [00:08:30] are about a million times smaller than an ant. So that for me gives me a sort of practical reference point as a chemist. It also makes sense to me to think of a five nanometer crystal as containing about a thousand atoms, but atoms are not necessarily a easy to understand lane skill for everybody. So the the ant is maybe a more common reference point, what natural materials have been created and what about them makes them [00:09:00] more promising than another depending on the realm of properties that you examine. Speaker 5: Promising has all sorts of different meanings, right? So things like semiconductor nano wires or perhaps graphene or carbon nanotubes may be considered promising for new electronic materials because the transport of electrons through these structures can proceed quite unimpeded and move very [00:09:30] readily so that we could have fast electronics or very conductive transparent thin films to replace the things we use today in our flat panel displays and so on. Other nano materials are very promising for diagnostics of different kinds of diseases or even for therapy of different kinds of health issues. So there are biological probes being developed that can be directed into specific areas [00:10:00] of your body. For example, where a tumor site is located using a nanoscale magnet and then they also carry a payload of drugs that can then be released specifically at that site. So you could have targeted therapies. So these sort of multifunctional nano constructs are very interesting. Speaker 5: I would say promising in the long run for for new targeted therapies, I have many fewer side effects than these broad spectrum drugs that we commonly use today. In terms of coming up [00:10:30] with new nanomaterials, is it as often the case that you are trying to create something for a specific purpose or that you accidentally find something that has a characteristic that can be applied pretty widely or to a specific use? I think that much of Nano materials research is motivated by the investigation and discovery of new phenomenon. And I distinguish that from targeted application [00:11:00] focused development because it's often unclear what a new material or it's phenomenological characteristics will actually be useful for. In my lab. Uh, we do tend to think of practical connections, but then the ones that we ultimately realize could be very different from the one that motivated us at the outset of the project. So I think as a scientist it's important to be attuned [00:11:30] for surprising opportunities to apply materials in ways you didn't anticipate. And so you have to be aware of the needs that are out there, the big needs in society, basically paying attention for how the phenomena you're discovering might map onto these societal needs. You probably as a scientist, not going to able to take Speaker 5: a new discovery all the way through to a practical application. But if you don't at [00:12:00] least identify those connections, it will be difficult for engineers and industry to take your discoveries and turn them into practical applications. So there's a role on both sides to make that connection. Speaker 4: [inaudible] you are the deputy director of the molecular foundry at Lawrence Berkeley National Lab. Tell us about the foundry and the work going on there. Speaker 5: So the molecular foundry is a very special place. It's one of five department of energy funded [00:12:30] nanoscale science research centers, which are located around the country. And we have the mission of pushing the forefront of nanoscience broadly defined, so nanoscience in all different aspects while at the same time acting as a user facility to help others in the scientific community, be they academic researchers, industry, others at national labs move the science in their areas forward by leveraging the tools of nanoscience. [00:13:00] So it in effect, it becomes this amazing hub of activity and nanoscience where people from really all around the world are coming to us to leverage capabilities that we are continuously advancing and developing in different kinds of nanoscience be it inorganic nanocrystals, which is my focus theoretical methods for treating nanoscience completely out of this world. In my mind, I'm spectroscopic techniques [00:13:30] for looking at nanostructures.Speaker 5: All these things are being developed at the foundry, at the absolute bleeding edge of nanoscience, and these can have impact in all different areas. And so our users come, they work with us, they learn these state of the art techniques, generate new materials that they can take home with them to their own laboratories, integrate into their materials and processes and devices and so on or do their a specialized characterization on and the amount of science that results by [00:14:00] that multiplication and leveraging is really very exciting to watch. Oh, it's a hub. It's an intersection of ideas in one place of problem, motivations from different perspectives and then it branches right on back out to impact science and in all different ways. Speaker 4: What sort of a funding horizon are you on? Speaker 5: Uh, so we have very stable funding from the Department of Energy. These centers are quite new. They were only established [00:14:30] over the last 10 years. The foundry has been in full operations for about six years and they are very much the flagship capabilities of the office of science within the Department of Energy and will be for quite some time to come. So they're making a very stable and continued investment in this area and continue to see the value and opportunity for really in the end, American economy, taxpayers and industrial [00:15:00] innovation that's generated by all of this scientific activity. Speaker 2: [inaudible]Speaker 4: you were listening to spectrum on k a l x Berkeley, Delia mill, iron of Lawrence Berkeley national lab is talking about her work in nanoscience and nanotechnology. Speaker 2: [inaudible]Speaker 4: what's the focus of your research? Speaker 5: So my research involves the [00:15:30] innovation of Inorganic nanocrystals, which are a few nanometers diameter crystal and arrangements of atoms. And they're using these as building blocks to construct materials. So we put them together with each other and two, for example, porous architectures, or you put them together with polymers or we put them together, uh, with glassy components to construct macroscopic materials often than films. And we're interested [00:16:00] in these primarily for their electrochemical functions. So electric chemical devices are useful for things like batteries, supercapacitors a storing energy also for converting energy. And in our case, we've most recently been focused on electrochromic window applications. So these are function like batteries, but instead of storing charge, they have the effect of changing the tint on a window dynamically as a function [00:16:30] of voltage. But everything starts with the nanocrystals and new ways to put them together with other components to construct materials. Speaker 4: And is the crystal material something unusual or is it real commonplace? Speaker 5: It varies actually. Most of the materials that we craft into nanocrystals are well known and have been studied for a long time in their bulk form. So just as in the example of gold being very different in both and obviously useful for [00:17:00] all sorts of things like currency now having very different function on the Nano scale. We work with materials that maybe are not quite as common places goal, but nonetheless fairly common. So one material we've been working with a lot lately is called indium tin oxide. And whether you know it or not, you probably use it every day. It's the material that provides conductivity in flat panel displays, touch screens, all of these sorts of things. And so in it's normal thin [00:17:30] film form, it's obviously very well established and used around the world for all different applications. It was only synthesized in a well controlled way as Netto crystals in the last few years. Speaker 5: And in the Neto crystal form, it has all of these wonderful properties relating to electric chromic windows. And beyond that it has, I guess I should say more fundamentally, the phenomenology underlying those windows applications is that this [00:18:00] material is plasmonic, which means that it can effectively condense a near infrared light to a very small scale, can amplify the electric field from the light, basically manipulate light in a new way. And people have been doing this with metals like gold as one example. Silver is another for a while, and a whole new field of plasmonics has emerged. Um, now with Ito on the nanoscale, we're bringing [00:18:30] plasmonics into the infrared region of the spectrum, which is going to give us whole news opportunities for manipulation of light of that sword, channeling light and so on. So the, as I was saying earlier, the phenomenology is where we spend the most time and discovery of these plasmonic characteristics of Ito is going to lead to many, many applications.

More information on the series is available@nativeplants.org Speaker 1: [00:26:00] beginning on December 26 the Lawrence Hall of science will begin screening and interactive program in their planetarium called constellations. Tonight. A simple star map will be provided to help participants learn to identify the most prominent constellations of the season in the planetarium. Sky. Questions and activities will be part of the program. The presentation will continue until January 4th and will be held every weekday from two to 2:45 PM [00:26:30] tickets are $4 at the Lawrence Hall of science after the price of admission. Remember that's beginning on December 26th [inaudible] Speaker 7: with two news stories. Here is Rick Karnofsky and Lisa kind of itch. Nature News reported on December 11th Speaker 1: that the u s national ignition facility or Nif at Lawrence Livermore national laboratory is changing directions. Nip uses a 192 ultraviolet laser beams that interact with the gold capsule, creating x-rays. These x-rays [00:27:00] crush a two millimeter target pellet of deuterium and tritium causing fusion. Nif has not yet achieved ignition where it may deliver more energy than it consumes I triple e spectrum criticized the project for being $5 billion over budget and years behind. Schedule in the revised plans [inaudible] scale back to focus on ignition and would devote three years for deciding whether it would be possible. It would increase focus on research, a fusion for the nuclear weapons [00:27:30] stockpile stewardship program and basic science. It would also devote resources to other ignition concepts. Namely polar direct drive on Omega at the University of Rochester and magnetically driven implosions on the San Diego z machine. The Journal. Nature reports that rows matter a natural plant die once price throughout the old world to make fiery red textiles has found a second life as the basis for a new green [00:28:00] battery chemist from the City College of New York teamed with researchers from Rice University and the U S army research lab to develop a nontoxic and sustainable lithium ion battery powered by Perper in a dye extracted from the roots of the matter plant 3,500 years ago. Speaker 1: Civilizations in Asia and the Middle East first boiled matter roots to color fabrics in vivid oranges, reds, and pinks. In its latest incarnation, [00:28:30] the climbing herb could lay the foundation for an ecofriendly alternative to traditional lithium ion batteries. These batteries charge everything from your mobile phone to electric vehicles, but carry with them risks to the environment during production, recycling and disposal. They also pumped 72 kilograms of carbon dioxide into the atmosphere for every kilowatt hour of energy in a lithium ion battery. These grim facts have fed a surging demand to develop green batteries [00:29:00] growing matter or other biomass crops to make batteries which soak up carbon dioxide and eliminate the disposal problem.
