Podcasts about pmma

Neste episódio do podcast do Fantástico, Renata Capucci e Maria Scodeler recebem a cirurgiã plástica e conselheira federal por Santa Catarina Graziela Bonin e a influenciadora Mariana Michelini, que perdeu o lábio em uma harmonização com PMMA – sem que ela soubesse que o produto estava sendo usado.

A Agência Nacional de Vigilância Sanitária, a Anvisa, avalia a retirada do polimetilmetacrilato, o PMMA, após solicitação do Conselho Federal de Medicina (CFM), para proibir o uso desta substância para fins estéticos. O requerimento foi entregue na última terça (21) durante reunião na sede do órgão regulador, e pede o banimento e suspensão da produção e da comercialização de preenchedores à base do produto no Brasil. Mas o que é o PMMA? Quais os riscos e consequências do uso desta substância? Em quais procedimentos ele é utilizado? Para quem ele é indicado? E quais profissionais podem realizar as aplicações? Luiz Fara Monteiro e a repórter Caterina Achutti conversam com André Perez Pontes, cirurgião plástico do Hospital Moriah.

Justiça dos Estados Unidos bloqueou o decreto de Donald Trump que negava cidadania a filhos de imigrantes ilegais ou com visto temporário, mas deputados aumentam os poderes de autoridades para prender imigrantes sem documentos que sejam acusados de crimes. Trump desafiou a independência histórica do banco central americano e disse que vai exigir a redução imediata dos juros. O Conselho Federal de Medicina pediu que a Anvisa proíba a venda de PMMA. O produto usado em procedimentos estéticos já causou mortes quando usado indevidamente. A polícia investiga o destino final da carne estragada nas enchentes do Rio Grande do Sul. O cinema brasileiro conquista um marco histórico. O filme "ainda estou aqui" recebeu três indicações ao Oscar: melhor filme, melhor filme internacional e melhor atriz, para Fernanda Torres.

In the ever-evolving world of dental technology, staying ahead of the curve is essential for both practitioners and patients. This week we talk with Dr. Nilo Hernandez and Johnny O., who are making waves in the industry with their groundbreaking SiOS system (https://siosdental.com/). This innovative approach promises to revolutionize the way full arch dentistry is performed, offering a more efficient and precise method that benefits both dental professionals and their patients. Dr. Nilo Hernandez, a seasoned implantologist with over 35 years of experience, and Johnny O., a dental technician with a wealth of digital expertise, have joined forces to address the challenges faced in full arch dentistry. Their collaboration led to the development of the SiOS system, a digital workflow designed to streamline the process and eliminate common issues encountered during implant procedures. The SiOS system stands out for its ability to adapt to any implant system and surgical workflow, thanks to its unique use of beacons or matchmakers. These elements allow for precise placement and alignment, ensuring a better than printed full arch in just a few hours. This means that dental professionals can now offer their patients a more predictable and less invasive experience, with reduced chair time and improved outcomes. Dr. Hernandez and Johnny O. shared their journey from the initial concept to the fully realized SiOS system. They discussed the challenges they faced, such as the need for a digital solution that could work in both guided and non-guided environments. Their perseverance and dedication to problem-solving led to a system that not only meets these needs but also elevates the standard of care in implant dentistry.

Entrevista com o cirurgião plástico, doutor Thyago Lemos, falando sobre os possíveis riscos na realização de procedimentos estéticos e os recentes casos mal sucedidos com o uso de PMMA.

In the episode 10 of fire fundamentals together with David Morrisset, a nearly graduated PhD student from the University of Edinburgh, we explore the intricate dynamics of flame spread and its crucial role in fire safety engineering. David helps us differentiate between the two primary modes of flame spread, concurrent (imagine upward spread) and opposed (imagine downward spread), and explains how understanding these mechanisms can significantly enhance building safety and fire risk mitigation.In this episode, we take a closer look at various materials like PMMA and timber and their unique fire behaviors. We also examine the complexities of flame spread on charring solids such as timber, discussing how pyrolysis and the resulting char layer influence heat transfer and flame behavior.Lastly, we dissect the heat transfer mechanisms in various materials, from foams to solid slabs, and how factors like orientation and material properties affect flame spread rates. David highlights the balance between gas phase and solid phase heat transfer and the importance of precise modeling to predict flame behaviors accurately. Phemonena discussed here:flame spread definitionconcurrent vs opposed flame spreadregimes of flame spreaddriving mechanisms of flame spreadFurther reading: Quantifying the controlling mechanisms of opposed flow flame spread: Influence of orientation, material, and external heating Characterization of Flame Spread Over PMMA Using a Temperature Reconstruction MethodThe relative position of pyrolysis onset and flame front location for downward flame spreadAnd even though we did not have time to discuss diagnostics in the episode, you can check this crazy paper of David:Assessment and application of phosphor thermometry for spatially resolved surface temperature measurements during downward flame spreadCover image: edited from Figure 1 in https://doi.org/10.1016/j.firesaf.2023.104048----The Fire Science Show is produced by the Fire Science Media in collaboration with OFR Consultants.

Host: Jennifer Warmann-BlossGuest: Tabitha Braun, Nurse Practitioner and Expert in Cosmetic ServicesEpisode Overview: In this episode of "Beyond the Mirror," we dive deep into the topic of fillers, a subject that raises many questions and concerns in the aesthetics industry. With over 22 years of experience, our host shares insights alongside guest expert Tabitha Braun. They discuss the types of fillers, where and why certain areas should or shouldn't be filled, the importance of dissolvable fillers, and share some horror stories to underline the importance of choosing the right products and injectors.Key Points Discussed:Types of Fillers: The safety and versatility of Hyaluronic Acid (HA) fillers due to their dissolvable nature. Risks associated with non-dissolvable fillers like Collagen and PMMA, highlighting horror stories from real experiences. The distinction between safe fillers and those posing potential risks due to their permanent nature. Areas of Caution for Filler Injection: Under-eye, temple, and between the eyebrows are highlighted as high-risk areas due to potential complications, including vascular occlusion and necrosis. The importance of correct product placement and the role of the injector's expertise in achieving natural-looking results. The debate around filling the nasal labial folds and the potential for unnatural outcomes. Horror Stories and Lessons Learned: Real-life incidents underscoring the gravity of choosing experienced professionals and the right type of filler. Stories include severe reactions to permanent fillers leading to surgical interventions and lifelong disfigurement. Advice for Potential Patients: The significance of conducting thorough research, asking for before-and-after photos, and understanding the injector's aesthetic style. The importance of using dissolvable fillers for safety and reversibility. Recommendations for starting with less invasive areas and considering the long-term effects of aging on filler placement. Closing Thoughts: A reminder of the inherent risks in cosmetic procedures, balanced by the potential for beautiful results when performed correctly. An invitation for listeners to suggest topics or questions for future episodes, emphasizing the podcast's commitment to education and dialogue in wellness and aesthetics.Disclaimer: Information provided in this episode is for general knowledge and not a substitute for professional medical advice.Hosts Contact Information: Website: www.elementalwellnessandlongevity.com www.elementalesthetics.com Social Media: www.instagram.com/ElementalWellnessandLongevity www.instagram.com/ElementalEsthetics www.facebook.com/ElementalWellnessandLongevity www.facebook.com/ElementalEsthetics

If the word 'uncertainty' sounds extremely boring to you, this episode will prove you wrong. I have invited David Morrisset from the University of Edinburgh to discuss his research on the subject. Whereas in fact David is establishing standard deviations, means and other statistical means of quantifying uncertainty in core fire measurements, the really impactful and important part of his research is on explaining WHY those uncertainties are there. Through physical explanation of processes happening in fire we may grasp a really good understanding why two HRR-time curves of the same object burned in the same lab, in the same way may be so vastly different.These findings are fundamental for practical fire engineering. The establishment of design fires and their relation to the experiments is discussed in depth. We also talk about how we could establish better design fires for future engineering practice.Some excellent further reading:Repeat Fire Tests of Upholstered Furniture: Variability and Experimental Observations - the upholstered chair paperStatistical uncertainty in bench-scale flammability tests - the PMMA paper 

In this BackTable MSK episode, host Dr. Jacob Fleming interviews Dr. Alan Sag about techniques and advancements in bone cryoablation. Dr. Sag is an interventional radiologist at Duke University Medical Center. To start, Dr. Sag discusses his current practice and collaboration with orthopedic surgeons. He highlights IlluminOss, a new photodynamic bone stabilization system that uses similar concepts to endovascular balloons. Then, the doctors move onto discussing cryoablation, which was recently cleared by the FDA for use in pain palliation in bone metastases. Dr. Sag describes the procedural steps of cryoablation, pneumodissection with carbon dioxide, when to use polymethylmethacrylate (PMMA) augmentation, the value of same session biopsy, and education for referrers and patients. Cryoneurolysis and intrathecal pain pumps are also discussed, as they can offer additional pain relief for patients and reduce opioid dependence. --- CHECK OUT OUR SPONSOR Stryker Interventional Spine https://www.strykerivs.com --- SHOW NOTES 00:00 - Introduction 03:20 - Collaboration with Orthopedic Surgery 08:57 - FDA Clearance for Cryoablation 14:47 - Cement Augmentation after Cryoablation 19:22 - Approach to the Cryoablation Procedure 26:57 - The Value of Same Session Biopsy 29:11 - Coordinating Cross-Specialty Oncologic Care 33:30 - Side Effects of Cryoablation 38:03 - Cryoneurolysis for Pain Reduction 45:40 - Skin Safety During Cryoablation 50:58 - Preferred Imaging Modalities 57:28 - Neuromodulation with Intrathecal Pain Pumps --- RESOURCES Symposium on Clinical Interventional Oncology (CIO): https://www.hmpglobalevents.com/cio BackTable VI Ep. 221- Building a Musculoskeletal Oncology Service Line with Dr. Alan Sag: https://www.backtable.com/shows/vi/podcasts/221/building-a-musculoskeletal-interventional-oncology-service IlluminOss Photodynamic Bone Stabilization System: https://www.illuminoss.com/eu BackTable VI Ep. 401- The MOTION Study: Cryoablation for Painful Bony Metastases with Dr. Jack Jennings: https://www.backtable.com/shows/vi/podcasts/401/the-motion-study-cryoablation-for-painful-bone-metastases BackTable VI Ep. 284- Ortho/IR Collaboration in Private Practice with Dr. Tony Brown & Dr. Daniel Lerman: https://www.backtable.com/shows/vi/podcasts/284/ortho-ir-collaboration-in-private-practice BackTable MSK Ep. 25- Advanced Minimally Invasive Pain Interventions with Dr. David Prologo: https://www.backtable.com/shows/msk/podcasts/25/advanced-minimally-invasive-pain-interventions Pneumodissection for Skin Protection in Image-Guided Cryoablation of Superficial Musculoskeletal Tumors: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5499669/ BackTable MSK 40- Innovating Pain Management: The Role of Spinal Cord Stimulators in Outpatient Care with Dr. Doug Beall https://www.backtable.com/shows/msk/podcasts/40/innovating-pain-management-the-role-of-spinal-cord-stimulators-in-outpatient-care

When someone in the industry seems to spend more time teaching others than working on their own work, we want to learn more. Elvis had the opportunity to take a 2 day hands-on course about pink layering on full arch zirconia and PMMA. The teacher was the wonderful Marina Caponigro (https://www.facebook.com/marina.ya.7). Of course, we had to have her on the podcast to learn about the technician behind the "fire in the belly". Marina talks about coming to America from the Ukraine to marry and work with a Prosthodontist, learning to do full arch restorations and perfecting the pink layering of composites and stains. It wasn't long before she was encouraged to teach others and travels the country teaching both technicians and clinical staff. Wanting to do more for others, Marina and her daughter opened the Smileology Group Dental Lab specializing in helping other labs create beautiful full arch restorations.

Comentario: De La Leche De Burra Al PMMA. Por: Marta Escurra by ABC Color

If someone ever tells you they have modelled fire spread for a commercial project, with 20 cm grids and using generic materials from (old) FDS database, please do me a favour and redirect them to this episode. Because modelling fire is a seriously challenging thing. And by modelling, I really mean it.  Not to apply a surrogate source based on a statistical overview of how fires looked like in the past for fuels of this kind. Not to omit half of the phenomena because they are too hard and in cone they did not matter anyway... To really model the fire.I have invited prof. Lukas Arnold from Bergishe University Wuppertal and Juelich Forszungszentrum to tap into how challenging modelling even simple materials may be. What are the feedback loops and phenomena one must account for, and how do different scales give us different parts of the answer we need? If you would like to know more about Lukas efforts in modelling, please check two recent papers:- Paper on cone calorimetry of different types of PMMA (the material we have discussed in the podcast episode) - Paper on inverse modelling the pyrolysis kinetics - giving insight into how one obtains the material data you may need for modelling.

In episode 66 of Cracking Addiction we discuss MDMA or ecstacy and discuss its analogues PMA and PMMA and discuss the pharmacokinetics of these drugs, the unique properties of MDMA as both an atypical amphetamine-type substance and its effects as an empathogen. We also discuss the usage as both a recreational drug but also the new and emerging evidence of the clinical effects and benefits of MDMA and its increased usage in medical practice. MDMA has many effects on the body and we discuss the effects of MDMA on the brain, heart and liver in particular as well as some of the side effects of MDMA.Latest Blogshttps://www.meducate.com.au/blogAbout Meducate ®Meducate provides online education for doctors, clinicians, health professionals and the public.See the website to browse the many different talks and courses available https://www.meducate.com.au

Have you seen the high prices of precious metal these days? They are close to record highs on gold and palladium. With those high precious metal prices, you are paying a high cost for your alloys. We know that you are using less Precious metal in your lab these days, but if you send in half of what you sent in 5 years ago ,your scrap return will be higher than it was 5 years ago ,because of the high PM prices .

At Kulzer (https://www.kulzerus.com/en_us/en_us/home_9/home.aspx), they take the extra step to X-ray the top and bottom after they melt the bar to make sure the precious metal percentages--- are the same. If not, copper is added until they are positive the bar is homogeneous. We know this step is very important to get a precise assay result.

Siliconpolitik: Where Do We Go Now?— Pranay KotasthaneI have a follow-up paper for NUS-ISAS discussing the next steps for the Quad Semiconductor Supply Chain initiative. I argue that the Quad Principles Document on Technology Design, Development, Governance and Use is a good reference point for the collaboration on semiconductors.An initiative to map capacity and identify vulnerabilities is a welcome first step. However, a lot more needs to be done to create a secure, resilient semiconductor supply chain. Another vital document released on 24th September — the Quad Principles on Technology Design, Development, Governance, and Use document — serves as a helpful guide for realising the ultimate goal. This section maps key principles in the document to potential initiatives in the semiconductor domain.One, the document on principles argues that resilient, diverse, and secure technology supply chains are vital to the shared national interests of the Quad countries. To achieve this goal, the document advocates "close cooperation on supply chains with allies and partners who share our values” since this “will enhance our security and prosperity, and strengthen our capacity to respond to international disasters and emergencies."A way to map this principle to the semiconductor domain would be to form a Quad semiconductor consortium that manages a jointly held Quad Supply Chain Resilience Fund. This consortium can then create a roadmap for new semiconductor manufacturing facilities across the Quad countries. The goal should be to ensure redundancy in the ecosystem such that this supply chain is not susceptible to geopolitical or geographic risks. For instance, while the US focuses on restarting manufacturing at leading-edge nodes (5 nanometres and below), the consortium could work together to build specialised analog, memory foundries operating at trailing-edge nodes (45nm and above) in India, Japan, or Australia.Another way to realise this principle is for the consortium to create one centre for excellence (CoE) in each Quad country in an area of its immediate interest. For example, Australia could host the CoE for new materials in electronics, Japan could host the CoE for silicon manufacturing equipment, while the US and India could host CoEs on fabless design architectures.Two, the principles document recognises the importance of "international standards development that foster interoperability, compatibility, and inclusiveness." This principle can translate into cooperation on developing new standards for open-standard instruction set architectures such as RISC-V and for manufacturing on semiconductor composites such as Gallium Nitride.Three, the principles document underscores that the Quad countries are "committed to facilitating the exchange of researchers and movement of highly skilled personnel to enhance science and technology collaboration". This applies well to semiconductor R&D cooperation, where governments can do a lot to foster technology exchange, visitation and research participation, and joint development between companies in the Quad countries. For instance, lowering employment barriers for semiconductor professionals in the Quad countries could facilitate more joint development. Beyond skilled personnel movement, lowering investment barriers and export controls within the Quad bubble can facilitate more cross-licensing arrangements.Further, I identify three key factors that could determine how far this initiative goes:One, the US needs to review its approach to technology protection in the semiconductor domain. Given that US-headquartered companies alone account for 62 per cent of global fabless firm revenues and 51 per cent of global integrated design manufacturers (IDM) revenues, the US role in creating a resilient supply chain is critical.In the past, the US government adopted strict trade and regulatory mechanisms restricting technology transfer. This restrictive approach needs to give way to a collaborative mode in the Quad. In a paper titled "An Allied Approach to Semiconductor Leadership", Stephen Ezell lists some measures that the US could take. These include enrolling partner countries in trusted foundries programmes, co-investing in semiconductor moonshots, reducing export controls, lowering foreign investment screening barriers with like-minded countries, and sharing information on intellectual property theft. Just as the US is now willing to share critical technologies with partners through the AUKUS defence arrangement, an allied approach should be adopted in the semiconductor domain.Two, all four Quad countries need to work to increase trust in each other's legal enforcement mechanisms. The four members need to harmonise their contract enforcement, regulatory practices, and patent protection mechanisms. Such measures will encourage companies to collaborate across borders.Three, the Semiconductor Supply Chain Initiative should become a platform that coalesces other powers in this domain, such as Taiwan, South Korea, Israel, Singapore, and the European Union (EU). The larger the grouping of like-minded countries, the more resilient and secure the semiconductor supply chain is likely to be. What do you think?Antriksh Matters #1:Lab On A Chip for Space Missions— Ruturaj GowaikarIndian Space Research Organisation (ISRO) and Indian Institute of Science (IISc) have jointly prepared a device to conduct cell biology-based experiments in space. The device, called MANAS, Sanskrit for Mind  stands for Microbial Analysis in Space. It  is a technology demonstrator and uses the lab-on-a-chip (LOC) concept. The details of this device were published in the Journal Acta Astronautica.Cell-biology experiments in spaceMicrogravity, as experienced in space, be it in low earth orbit (LEO) or outer space, can affect various cell processes at the cellular and subcellular level. These effects can vary from alteration to the cytoskeleton and shape of a cell, to alteration in the metabolism of cells. The effect of this is that pathogenic microbes might behave differently in space and insight into their growth dynamics can have a bearing on the health of personnel involved in manned-space missions. Altered growth rates  also affect microbial output of space bioreactors being developed for manned missions. The aim of these bioreactors is to produce protein-based medicines, help in recycling water on-board etc.  in order to reduce frequency of re-supply missions. India’s manned space mission- Gaganyaan – is underway and platforms like MANAS are useful to conduct preparatory experiments for future missioClonger durations.Design of MANASMANAS is a milli-fluidic device that was fabricated using 3D printing while some components were CNC machined. It consists of a cylindrical cavity in an aluminum block called the bacterial chamber and some smaller antechambers. It is surrounded by optically transparent material (PMMA) plates. This allows the LED and photo-diode sensors to measure optical cell density-the standard way to count cells using principles of spectroscopy. It has a modular design so multiple such chambers can be housed together to form cassettes designed specifically to conduct one experiment. Such multiple cassettes can also be loaded as cartridges to perform different experiments. The device has a microcontroller to initiate the experiment remotely, measure the optical density (OD), and store data on-board.MANAS was tested using the spore forming bacteria Sporosarcina pasteurii. The bacteria were deactivated metabolically by converting them into spores. Spores were then lyophilized and suspended in a sucrose solution and loaded into MANAS, while the nutrient media was kept in a different chamber separated by a NC solenoid. The OD scores were a readout for the growth and were used to prepare growth curves. The growth curves were cross-validated using electron-microscopy. MANAS was tested under vacuum conditions and altered atmospheric conditions as well.The bacteria chosen is also significant because it is an ureolytic bacteria and thus can prepare calcium carbonate crystals. ISRO research on this bacterium has made it a contender to form space bricks for lunar habitation.Thus, this self-contained, leak proof, orientation-agnostic, remotely operable LOC platform is one small step in the right direction  for India’s space research programme. The next step is to test it in flight mode and design more complex experiments.Antriksh Matters #2: Lessons from UK’s National Space Strategy— Aditya PareekThe UK has come out with its first ever national space strategy document. The document builds on the UK’s Integrated Review and Defence Command Paper that came out earlier this year and featured space prominently.The strategy document has several aspects which any similar strategic publication on space by India could also take inspiration from and integrate:1. A focus on “Whole Ecosystem Approach” for the advancement of the Indian space sector.2. Focus on procurement of dual-use space technologies and platforms for the fulfilment of national space goals - without compromising on the deliverable specs.3. Focus on making space sustainable by actively contributing to space debris removal, and explore technologies and services that may extend the service life of satellites and other space objects while in orbit.4. Earmarking a venture capital fund for private finance access to New Space sector companies - along the lines of UK’s Seraphim Space Investment Trust.5. Acknowledge the operating environment vis a vis adversarial counterspace capabilities and include a back-of-the-envelope estimate for potential damage they can inflict on Indian economy.Check out the All Things Policy Podcast featuring our take on the UK’s national space strategy here.If the content in this newsletter interests you, consider taking up Takshashila’s short course on Evidence-based policy-making for responding to COVID-19.

This comes on the back of the Quad summit, where technology played an important role in the discussions, especially in outlining the main objectives of the ‘Critical and Emerging Technologies Working Group’ by the alliance. It is also following the declaration of the AUKUS pact, with the US and UK signing agreements to transfer nuclear submarine technology to Australia. The rise of China and its influence on the global technology ecosystem through its tech giants have made the West, and especially the United States, take a fresh look at mechanisms for regulating and using critical technologies. Despite sharing concerns with regard to China’s technological growth and the global semiconductor chip shortage, the US and EU have very differing views on how to regulate the use of technology. The new EU-US technology council will have a hard time navigating the partnership as it looks to counter China’s tech dominance. Trying to Find a Middle GroundThe European Union’s approach to regulating and governing technology has evolved from an individual-centric approach keeping in mind the rights of its citizens. Fundamental rights like privacy have been accorded the greatest importance when it comes to framing laws related to technology. This can be seen from the General Data Protection Regulation (GDPR) Act, which addresses data protection and privacy in the European Union along with protecting personal data from being shared outside the EU area. The EU has been willing to intervene when it feels that the rights of European citizens have been infringed upon by any public or private entity. The United States, on the other hand, has always followed a minimal regulatory framework on technology. It has stressed how multiple rules and regulations might hamper the growth of emerging technologies. Following a market-driven and hands-off approach to governing technology, the United States has let the private sector and institutions take the lead while providing just minimal responsibilities to the state. This makes it necessary for both the actors to arrive at a compromise. But this kind of differential pattern also allows for both to complement each other’s strengths. The partnership can eventually help the EU obtain the geopolitical relevance that the US owns in the field while the US can obtain the rights and freedoms relevance that the EU policies champion. However, this requires political alignment which is yet to be seen between the two. Time will tell whether both will compromise on the principles they follow while regulating technology.The French Reservation While the first summit of the US-EU TTC focused on the ongoing semiconductor shortages, regulation of artificial intelligence technology, and the upholding of competition in tech, reports said that there were some grumblings from a certain EU member regarding the discussions which took place at the summit. French diplomats specifically asked to remove certain clauses and language which referred to a proposed semiconductor supply chain that mentioned the mutual dependency between the US and EU.France also has differing opinions when it comes to the security of supply aspects with it looking beyond just semiconductor chips as a potential shortage of supply. This has made the French stress on a rather cautious approach towards a potential US-EU partnership, with it emphasising the need to rebuild transatlantic trust.The French anger over the AUKUS deal seems to have subsided but the overall reservation they hold can put the brakes on the working of the TTC, which looks to take off soon.What will the focus be on?The EU comprises over 25 different countries with contrasting views and interests. Other than the China-centric focus, the EU partnership with the US should be driven by easier access to and dissemination of technology. Foreign investments in each other’s regions and reducing dependencies on global supply chains of critical technologies should be the focus of the TTC. Better collaboration in the research and development field of emerging technologies between technically advanced blocs like the US and EU can eventually act as a counterbalancing measure against the increasing Chinese influence.The question which remains is, will the US and EU’s common anxieties and fears help to forge a credible working partnership or will the dream of a transatlantic technology group remain just a dream? George W. Bush and Barack Obama, during their time in office, tried bringing the EU to the table for better cooperation on technology but eventually failed. Will the rapid rise of China in the technology space during the past decade possibly provide a new impetus to the partnership?CyberPolitik : DCNs are trying Regulatory Fixes (Again, and again)— Sapni G KOver the past few editions, we have presented our working idea of what a Digital Communications Network is. Commentators across the globe have identified the difficulty in finding adequate regulatory responses to the fissures that appear in our lives that are intertwined with DCNs. We have also warned that regulatory fixes for the troubles of (some may say troubles caused by) DCNs are not easy to find. While policymakers across the globe scratch their heads looking for solutions, these DCNs have suggestions to offer. It is not the first time suggestions come from the very platforms that are due for regulation. Such overtures into policymaking have been attempted by every industry that attracted global attention, from telecom to tobacco. The technology industry itself has ventured into designing regulatory solutions. As governments are evidently not keen on this sort of self-regulation to continue, new tactics emerge from the playbooks of tech giants. Twitter released a position paper titled “Protecting the open Internet” on 13 October 2021. It outlines five broad guiding principles for the regulation of the internet. In short, it calls for the adoption of universal standards for the internet and its regulation, while adhering to established norms of human rights. It recasts the decades-old vision of a cyber utopia, which has sadly come crumbling down. Trust, competition, and transparency are central to Twitter’s recommendations. It proclaims that this vision would help big and small players alike, and honour the vision of the internet. Such documents or recommendations, called by their myriad titles, have been produced by every tech company and the multitude of people who helm them.However, things are different in practice. In response to regulatory warnings in Australia, a misinformation oversight committee was created within the Digital Industry Group Inc. (DIGI), an industry body publicly backed by Facebook, Google, and Twitter. This contradicts Twitter’s proclamations for open standards and giving space to smaller players. As India moves ahead in regulating DCNs, this experience gives us two valuable lessons. Firstly, taking the proclamations they make at face value might not be in the best interest of our society or the regulatory regime that we intend to create. Secondly, DCNs should have access to the policymakers’ tables, but it must be as limited as any other stakeholder group such as civil society or law enforcement agencies. Devoting more attention, time and regard may give way to them usurping the process to the possible loss of other stakeholders and industry players. Antriksh Matters #3: ISpA a new beginning? — Aditya RamanathanOn 11 October, India’s Prime Minister made a clear indication of the importance the government attaches to India’s commercial space sector. Launching the industry body, the Indian Space Association, the Prime Minister identified four “pillars” of space reform: freedom of innovation for the private sector, the role of the government as an enabler, preparing India’s young workforce for the future, and to see the space sector as a resource for the development of the wider populace. The founding members of the Indian Space Association are largely established vendors for ISRO. For instance, last year, Larson & Toubro provided a booster segment for ISRO’s Gaganyaan Launch Vehicle, that is key to India’s human spaceflight programme. Another long-time ISRO vendor is Walchandnagar Industries, which is presently helping to develop solid propellant boosters for the GSLV Mk III launchers. One of the newer companies on the list of founding members is OneWeb, the satellite internet company backed by a consortium of investors led by Bharti Enterprises. During the launch of the Indian Space Association, Bharti Enterprises chairman Sunil Mittal announced that OneWeb would soon become ISRO’s first private Indian customer for satellite launches. Other core members of the association include Hughes India, Centum Electronics, state-owned BEL, and Maxar India. That the Indian Space Association is dominated by ISRO’s vendors (barring exceptions like OneWeb), is a natural result of the way India’s space sector has evolved for decades, with private players simply acting as suppliers. The Indian Space Association will also presumably complement and compete with existing representative bodies like the Satcom Industry Association and Association of Geospatial Industries. Given the Indian Space Association’s backing from industry and the government (it will be headed by Lt. General A.K. Bhat, a decorated officer who retired from service last year), it will not be surprising if it supersedes the existing organisations.While the Indian Space Association will provide commercial space players a mechanism to both consult each other and approach the government, its success will ultimately depend on the receptiveness of the government. If India is to achieve the vision laid out by the Prime Minister, it will need to move faster. In 2020, it set up the regulatory body INSPACe under the Department of Space. However, it took until September this year to appoint Pawan Goenka, the former managing director of Mahindra & Mahindra as its chairperson. While the appointment of an auto industry stalwart (rather than a government official) was widely welcomed, it took too long, suggesting resistance from within the system. The government must now work to staff up INSPACe and respond quickly to what is reportedly a growing pile of pending applications from private players. More broadly, it provide a fresh set of regulations and policies that will allow India’s space industry to grow from vendors into world-class spacefarers. Our Reading Menu[Opinion] Robert Reich characterises the Supreme court of USA, Facebook, and the Fed as the horsemen of democracy’s apocalypse drawing a thread of unaccountability from them as wielders of great power. [Book] “On Operations” by Capt.

Simple, Predictable, Digital Denture Workflows (With or Without a Scanner) Episode #345 with Dr. Wendy AuClair Clark (Covid Conference) Dr. Wendy AuClair Clark loves digital dentures. And according to pilot studies, patients do too! Going digital speeds up fabrication, cuts down chair time, and can be less expensive. It's not just the dentist's workflow that improves, but also access to care for the denture population. What's not to love? If you're still not convinced, Dr. Clark demonstrates how the digital denture workflow is easy, predictable, and very low stakes. For more reasons to try digital today, listen to Episode 345 of The Best Practices Show! Main Takeaways: There is no longer just one workflow. Any step can now be digitized. Every single stage of your diagnostics is preserved with digital. Printing is generally a faster, less expensive way to digitally fabricate. Milling is usually stronger and more aesthetic. Milled PMMA will minimize staining, porosity, and fracture risk. You can reline, rebase, and repair milled PMMA dentures the same as conventional ones. The average digital denture workflow is about 2.65 visits versus 5 for conventional. With milled, there are fewer postoperative adjustments with digital versus conventional. In pilot studies, patients preferred every aspect of digital dentures over conventional. Digital can help close the access-to-care gap for older, edentulous patients. One downside is there are only short-term studies on first-generation printing. Quotes: “I heard a lab tech, Josh Jakson from Evolve, who really laid it out as simply as I've ever seen. And it's so true, that every aspect of digital dentistry can be put in one of three buckets: data acquisition, design, or fabrication. So, digital dentistry really is an easy thing. And you could take any aspect, so whether it's making a CEREC crown, you scan for the acquisition, you design it, and you mill it. And it's the same for digital dentures.” (03:44—04:09) “The other thing that I like people to be aware of is that there's not one workflow anymore, that truly any step can be digitized. And so, if you want to do a whole analog workflow and digitize one step, that's fine. If you want to do digital start to finish, that's fine too. So, it shouldn't be as exclusive, I think, as we tend to make it sometimes.” (04:20—04:40) “Printing, in general, is a faster, less expensive way to digitally fabricate, so the CAM portion of CAD/CAM. And milling is usually stronger and usually more aesthetic. But there are exceptions to every rule. So, this is just the basic blocks that they would fall into. Printing is going to be additive, so you're building it up. You have uncured resin that you're building in layers to create something. Milling is subtractive. I would say it's like when Michelangelo had a block of marble and he chiseled out David. That's what we're doing with our dentures. We're chiseling out these PMMA works of art.” (05:06—05:41) “For a milled denture, you can have a monolithic option. And they have a block from AvaDent, Ivoclar has a block as well, where basically the white and the pink are housed in the same puck of acrylic. So, it's kind of like an Oreo, is how it was described to me by the rep, where they have the pink on both sides, and the white in the middle. And the mill is aware of where the pink and white sit within that puck. And so, it's built in in the software to mill it out precisely. So, the teeth are white, the base is pink, but it's all monolithic. There's nothing bonded, nothing individual. It's a block of a denture. So, this is going to be your strongest and maximized tensile forces and functional forces. You could also have a bonded denture where you're going to have the bases milled, and then the teeth are bonded into the sockets.” (06:11—07:00) “Alternatively, if you don't want to work through a specific company, you can design and rig up your own monolithic denture. And this is what I've...

Many of us spend hours a week or even a day on social media. Checking up on friends and family, news, watching videos, looking at dental lab memes on the Voices From the Bench pages, or trying to grow our labs. Have you tried to grow your lab on social media?

Sumeet Jain is the Senior Director of 3D Printing Worldwide for Arkema. Previously Sumeet headed up Sartomer, the company's DLP and SLA resin brand, for seven years. Sumeet discusses with us how they make custom resins for applications and customers. Now, he's also responsible for their sintering powders, including the bio-based Rilsan polyamide 11, Kepstan PEKK, and Kynar PVDF, among other materials. We discuss Arkema's approach to the industry, its go-to-market strategy, and how 3D printing fits into the overall Arkema picture. We also talk about the materials themselves, such as PEKK and PVDF, as well as the company's PMMA for FDM, which us initially perplexing for us. We really loved having Sumeet on the 3DPOD and enjoyed his clear explanations and open approach to 3D printing. We hope you do to.

One would think that to bring a line of dental products geared towards full arch restorations to America you would have to know how to use it. Defying all odds, Tay Harvey took a degree in Journalism, a love for the mini implants, and a passion for the dental laboratory industry to bring anaxdent (https://www.anaxdentusa.com/) to North America. Tay talks about how she took a chance on a "little known" product line out of Germany mixed it with AMAZING marketing and turned it into a great company offering "hella" customer service. Aurident (https://www.aurident.com/) offers so much more than just the P5 michine (https://www.aurident.com/p5/). They offer all the needed accessories like Nabertherm furnaces (https://www.aurident.com/furnaces/) and vacuums by Renfert. And all the consumables can be got in one place! Aurident has Delta Zirconia (https://www.aurident.com/delta-zirconia/), Aurident Zr (https://www.aurident.com/aurident-zr-zirconia/), Aurident cutting tools, and Quest pmma (https://www.aurident.com/quest-pmma-shaded/) ! Aurident definitely is a One Stop Shop for any dental laboratory's needs! Call our friends, Aurident, at 800-422-7373 or visit their website at aurident.com! Few things create more interest today than the Digital Denture. Whip Mix (https://whipmix.com/) has developed a processing system for printed dentures, which uses Dentca (https://whipmix.com/products/dentca/), the first 3D-printed denture and denture teeth resins to receive FDA clearance. Their physical properties and biocompatibility pass FDA requirements and enable the printed denture properties to be very similar to conventional dentures. The material, coupled with fast and easy 3D-printing with Asiga printers (https://whipmix.com/products/asiga-max/) and the convenience of curing with a Uvitron UV light (https://whipmix.com/products/uvitron-uv-sunray-400-curing-unit/), results in fewer dentist visits, predictable fit, re-printable data files, lower costs and excellent intraoral denture performance. To learn how to create your own Digital Denture, check the Whip Mix (https://whipmix.com/) website for their Digital Denture courses and for more information about the system. Special Guest: Tay Harvey.

We all know how hard it is to find good, talented, and knowledgeable removable technicians. Even when good candidates get into the field, it's not an easy skill to train. Enter the Swiss School of Prosthetics (https://www.ssop.swiss/en). Steffen Rohrbach came to America with a German degree in dental technology and after a time in the Army, Steffen connected with Edmonds Dental Prosthetics (http://www.edmondsdentalprosthetics.com/) in Springfield, Missouri. With a passion and desire to train their technicians, they decided they also wanted to "raise the bar" in the whole industry on removable prosthetics. Connecting with Candulor (https://www.candulor.com/en-us), Steffen and Edmonds built a facility for the first Swiss School of Prosthetics in the US. Steffen talks about the journey becoming a teacher and what the courses have to offer to fellow labs and technicians.

Most of us think we have a pretty good team in our lab. But sometimes you run in to a couple of technicians that, when together, create great work and even better experiences. Conrad Rensburg came to this country as a trained dental technician and over the years eventually purchased Absolute Dental Services (https://www.absolutedentalservices.com/). Starting as a smaller lab and then growing to 6 locations, Conrad needed to improve and increase their product line. That's when Jack Marrano, the Director of their Signature Prosthetics Division, came in to train the technicians, improve their scalability, and bring in new technology. Conrad and Jack come on the podcast to talk about all that, plus getting into the Lucitone Carbon printed denture (https://www.carbon3d.com/materials/lucitone-digital-print/), strengthening their brand through social media, and participating in the dental laboratory industry.

Remember Lab Day Chicago? When dental technicians from around the world could get together with our worry or concern. When the pandemic hit every show, event, conference, and symposium got pushed to a later date or canceled. Most moved until 2021. But not Texas! Texas pulled off a successful IN-PERSON conference in early October. Unfortunately Voices From the Bench could not attend... physically. But our good friends at Argen, set up a booth with a computer and microphone, and got a ton of attendees and speakers to sit down and chat with us. It was fantastic talking to people again with the feel of being in person. This week kicks of a series of conversations we are calling "Live, Not Live From Argen (https://argen.com/#/) booth at the DLAT (https://members.dlat.org/membership/)". First up we chat with Matthew Douglas, the president of the DLAT. Then long-time fan of the podcast, Lauren Blanton, who actually moved far away and flew back to attend the conference talks with us about multiple CDTs and the grants that helped her get there. And we wrap it up with Dr. John Buie, who was "forced" to learn dental lab work in school, still does it in practice, and likes to share it with dental technicians. So sit back and imagine yourself in an in-person dental meeting and remember someday, soon, we will ALL be able to do this.

It's amazing how far zirconia has come in our industry. There are monolithic crown that have such good translucency that they rival lithium disilicate. But so many labs still layer them to get the desired results. Enter MIYO (https://jensendental.com/miyo/). the liquid ceramic that is taking the lab industry by storm (a name of one of their translucent colors). Don Cornell saw a need to improve the monolithic zirconia crown. To make it better. To make it look more like a natural tooth. With the resources of Jensen Dental (https://jensendental.com/) (already an expert in Zirconia and ceramics), Don was able to create a layering ceramic that gives the qualities of a natural tooth with less sacrifice of the crown material. Don talks about his early days, teaming up with Jensen, and how he and his team created MIYO.

Davantage de matériel médical, de masques et de visières, plus d’emballages dans l’agroalimentaire. L’épidémie de Covid-19 semble avoir favorisé le retour en vogue du plastique. Mais ce n'est qu'une apparence. La crise sanitaire aura redonné une certaine noblesse au plastique. Ses applications biomédicales sont devenues évidentes pendant l’épidémie de Covid-19, face à laquelle les soignants ont été en quête de respirateurs, de surblouses, et bien sûr de masques chirurgicaux et FFP2. Pour ces derniers on s’est arraché la matière première, le non tissé en fibres de polypropylène, spunbond et surtout meltblown, aux propriétés filtrantes incomparables. L’Europe en fabrique mais avant tout pour les produits d’hygiène, comme les couches culottes, ce ne sont pas du tout les mêmes machines, explique un professeur de l’ENSAIT, l’école d’ingénieurs textiles de Roubaix. Les prix du meltblown ont donc plus que décuplé. Course au meltblown pour les masques, tension sur le plexiglass Le contexte épidémique a également favorisé la production d’emballages alimentaires. Les consommateurs confinés ont fait plus de courses dans les supermarchés, et par prudence ils sont allés vers les denrées emballées, même les fruits, ce qui a favorisé la production de films alimentaires en PELD, de barquettes en PEHD, de bouteille en PET. Du PET également pour les visières que se sont mis à porter les salariés pour se protéger, en plus des masques. Les parois de plexiglass, le PMMA, ont aussi fait leur apparition devant les caisses. Enfin partout sur la planète, on s’est mis à se laver davantage les mains, or les canalisations, les citernes et baquets, sont en polypropylène ou en PET. Plus 30% dans l’emballage, moins 90% dans la construction et le bâtiment Mais ces nouveaux usages du plastique n’ont pas compensé l’effondrement d’autres débouchés. « Pour une croissance de 30% dans l’emballage et avant tout dans l’emballage alimentaire, on a vu les débouchés se réduire de 90% dans la construction et l’automobile », qui étaient à l’arrêt, rappelle Jean-Martin, le directeur général de la Fédération de la plasturgie. « Dire que le plastique a profité de la crise sanitaire n’est pas exact », juge-t-il. Défis pour le recyclage La filière du recyclage plastique a de son côté triplement souffert, de la baisse de 40% des volumes collectés, du plongeon des volumes écoulés et de la concurrence de la matière vierge. Depuis que le prix du pétrole s’est effondré, le PET vierge vaut moins cher que le PET recyclé (700 euros contre 1 150 la tonne). « Certains industriels de l’agroalimentaire ont quand même joué le jeu de l'emballage recyclé », se félicite Jean-Luc Petithuguenin, le président de FEDEREC. La Fédération des entreprises du recyclage promet qu’au démontage des parois de plexiglass, ses adhérents proposeront une collecte. Recycler les masques n'est en revanche pas encore envisagé, ils sont voués à l'incinération, s'ils ne sont pas jetés n'importe où mais dans les poubelles.

Cementing is an art.  The cement can be affected by the room temperature, humidity or how it is mixed.  When you apply PMMA you want to be sure that the bone surface is dry.  As you apply your implants you want to be sure not to alter the bone preparation or alignment, especially in osteoporotic bone.https://twitter.com/dradamrosenhttps://WWW.DRADAMROSEN.COMSupport the show (https://www.patreon/TotalKneeTips)

Introducing GuidedSMILE CHROME - DIGITAL, FULL-ARCH GUIDED RECONSTRUCTION GuidedSMILE was developed for dentists who desire a preplanned, predictable guided All-On-X style surgery. This amazing service delivers anchored bite verification, anchored bone reduction, anchored site drilling, accurate anchored provisionalization, and a method of transferring all surgical and restorative information for the final restorative conversion phase. Most cases simply require a CT scan and traditional records. Call to discuss your case. The process, the product, the surgery is straightforward! GuidedSMILE CHROME is a 4-Guide System 1 Pin guide - Utilizes teeth or tissue to deliver the Fixation Base (CR/CO SLM) Dentate Pin Guide is fully seated on the patient's existing dentition. Once verified via the two occlusal windows, the horizontal sites are drilled and anchored. Anchor pins are fully seated, verified and the guide is removed. Edentulous Pin Guide is a digital duplicate of the patient's existing denture. This tissue-supported guide is inserted, patient closes, and the anchor sites are drilled, anchored, verified, and the guide is removed. 2 Fixation Base - Use for bone reduction, anchoring the osteotomy guide and prosthetic Once teeth are removed and tissue is flapped, the Bone Reduction Guide is inserted, anchored, and bone is levelled to the meet the labial and lingual frame of the guide. This guide floats above the bone, and therefore should not be impinged by undercut. 3 Osteotomy Guide This guide is rigidly fixed with the pins, yet floats around the bone. Standard protocols are followed to drill sites and place implants. 4 PMMA Superior to conventional denture pick-up systems, this anchored GuidedSMILE nano-ceramic provisional transfers the CO/CR as determined by pre-surgical records. Implant abutment positions, anchor sites, tooth position, smile, and tissue space are all pre-set. 5 RAPID Appliance - The method of communicating GuidedSMILE to the articulator for the Final RAPID Appliance is ROE's special pick-up device, a clear duplicate of the PMMA. This allows the doctor to capture a second record to hold until final conversion. Once the patient is ready for the final, perform a pick-up impression, with tray adhesive on the tissue side, using medium PVS. Send this pick-up to ROE and we will GuidedSMILE Osteotomy Preparation Options Option 1 - GuidedSMILE-FG - All GuidedSMILE cases are utilize a Fully Guided Kit (as seen above) - ROE works with nearly all systems available today. Option 2 - GuidedSMILE-FH - Free-Hand - includes a location reference on the bone reduction frame to optimize implant location for PMMA pick-up, and a removeable reference inset to provide a maximum range for site preparation. Left image: notice the round divot references indicating implant general location. Right image: boundary insert used to ensure location of implants is within PMMA parameters.

Problemstellung: Aufgrund der hohen Umwandlung von CAD/CAM-Hochleistungskunststoffen während der Polymerisation gestaltet sich die Befestigung der Restauration am Zahn äußerst schwierig. Der Restmonomergehalt ist zu gering, um mit den Monomeren des Befestigungskunststoffes eine ausreichende Bindung einzugehen. Untersuchungsziel: In dieser Studie wurde untersucht, ob gezielte Konditionierungsmethoden zu einer Verbesserung des Haftverbundes zwischen CAD/CAM-Hochleistungskunststoffen und Befestigungskunststoffen führen können. Zur Bewertung der Haftqualität wurden nach Trennung des Verbunds eine Bruchbildanalyse durchgeführt und die Fehlertypen bestimmt. Material und Methode: Es wurden zwei verschiedene CAD/CAM-Kunststoffe (auf PMMA- und Komposit-Basis) untersucht (N = 600, n = 15 pro Versuchsgruppe). Die 300 Prüfkörper pro CAD/CAM-Kunststoff wurden in 20 Versuchsgruppen zu je 15 Versuchskörpern aufgeteilt. Vor dem Kleben wurden die Prüfkörper mit Aluminiumoxidpulver korundgestrahlt und anschließend konditioniert. Folgende Adhäsive wurden dafür verwendet: Monobond Plus/ Heliobond (MH), visio.link (VL), Ambarino P60 (AM), VP connect (VP), keine Konditionierung der Kontrollgruppen (KG). Befestigt wurde mit konventionellem (Variolink II) oder selbstadhäsivem Befestigungskunststoff (Clearfil SA Cement). Nach ihrer Fertigstellung wurden die angefertigten Versuchskörper für 24 Stunden in 37 °C warmem Wasser gelagert. Danach wurde die Hälfte der Prüfkörper zusätzlich einer thermischen Wechselbelastung mit 5000 Zyklen (5 °C und 55 °C) unterzogen. Anschließend wurde mit einer Universalprüfmaschine die Zugverbundfestigkeit gemessen und eine Bruchbildanalyse durchgeführt. Ergebnisse: Die Daten wurden mit Four- und One-way-ANOVA mit anschließendem Scheffé-post-hoc-Test, mit ungepaartem Zweistichproben-T-Test und Chi²-Test analysiert. P-Werte kleiner als 0,05 wurden als statistisch signifikant in allen verwendeten Tests angesehen. Kein oder nur ein geringer Verbund konnte bei beiden CAD/CAM-Kunststoffen für die unbehandelten Kontroll- und AM-Gruppen unabhängig vom verwendeten Befestigungskunststoff beobachtet werden. Dagegen führte die Konditionierung mit MH, VL und VP zu einer signifikanten Zunahme der Zugverbundfestigkeit. Grundsätzlich erwies sich der Haftverbund zu dem experimentellen CAD/CAM-Nanohybridkomposit als signifikant höher als der zu PMMA-basiertem artBloc Temp. Variolink II konnte jedoch in Verbindung mit artBloc Temp einen stärkeren Verbund erzielen. Bei Analyse der Fehlertypen zeigte sich, dass die Konditionierungen mit MH und VL überwiegend Kohäsionsbrüche mit Bruch im Befestigungskunststoff ergaben. Alle anderen Gruppen zeigten Klebeversagen. Die zusätzlich durchgeführte künstliche Alterung durch thermische Wechselbelastung wirkte sich nicht auf die Zugverbundfestigkeit aus. Im direkten Vergleich zeigte der Komposit-basierte CAD/CAM-Kunststoff eine höhere Verbundfestigkeit zu den untersuchten Befestigungskunststoffen als der PMMA-basierte CAD/CAMKunststoff. Schlussfolgerung: Die zu testende Hypothese dieser Studie wurde bestätigt. Durch gezielt ausgewählte Konditionierungsmethoden lässt sich die Verbundfestigkeit zwischen CAD/CAM-Hochleistungskunststoffen und Befestigungskunststoffen deutlich erhöhen.

The focus of this thesis concerns the morphology control of ordered mesoporous carbon (OMC) materials. Ordered mesoporous carbons with diverse morphologies, that are thin films, fibers – embedded in anodic alumina membranes and free-standing – or spherical nanoparticles, have been successfully prepared by soft-templating procedures. The mechanisms of structure formation and processing were investigated with in-situ SAXS measurements and their application in high capacity lithium-sulfur batteries was successfully tested in cooperation with Guang He and Linda Nazar from the University of Waterloo in Canada. The Li-S batteries receive increasing attention due to their high theoretical energy density which is 3 to 5 times higher than from lithium-ion batteries. For this type of battery the specific pore volume is crucial for the content of the active component (sulfur) in the cathode and therefore correlates with the capacity and gravimetric energy density of the battery. At first, mesoporous thin films with 2D-hexagonal structure were obtained through organic-organic self-assembly of a preformed oligomeric resol precursor and the triblock copolymer template Pluronic P123. The formation of a condensed-wall material through thermopolymerization of the precursor oligomers resulted in mesostructured phenolic resin films. Subsequent decomposition of the surfactant and partial carbonization were achieved through thermal treatment in inert atmosphere. The films were crack-free with tunable homogenous thicknesses, and showed either 2D-hexagonal or lamellar mesostructure. An additional, yet unknown 3D-mesostructure was also found. In the second part, cubic and circular hexagonal mesoporous carbon phases in the confined environment of tubular anodic alumina membrane (AAM) pores were obtained by self-assembly of the mentioned resol precursor and the triblock copolymer templates Pluronic F127 or P123, respectively. Casting and solvent-evaporation were also followed by thermopolymerization, thermal decomposition of the surfactant and carbonization through thermal treatment at temperatures up to 1000 °C in an inert atmosphere. For both structures the AAM pores were completely filled and no shrinkage was observed, due to strong adhesion of the carbon wall material to the AAM pore walls. As a consequence of this restricted shrinkage effect, the mesophase system stayed almost constant even after thermal treatment at 1000 °C, and pore sizes of up to 20 nm were obtained. In the third part, the aforementioned mesoporous films and embedded fibers in AAMs were further investigated concerning structure formation and carbonization in an in-situ SAXS study. The in-situ measurements revealed that for both systems the structure formation occurs during the thermopolymerization step. Therefore the process of structure formation differs significantly from the known evaporation-induced self-assembly (EISA) and may rather be viewed as thermally-induced self-assembly. As a result, the structural evolution strongly depends on the chosen temperature, which controls both the rate of the mesostructure formation and the spatial dimensions of the resulting mesophase. In the fourth part the syntheses recipes for AAMs were applied on a presynthesized silica template for synthesis of freestanding mesoporous carbon nanofibers. The syntheses start with casting of carbon nanofibers with a silica precursor solution leading to a porous silica template after calcination with tubular pores mimicking the initial carbon nanofibers. A synthesis concept using triconstituent coassembly of resol, tetraethylorthosilicate as additional silica precursor and Pluronic F127 was applied here. The silica from the additional precursor was found to be beneficial, due to reduced shrinkage and created additional porosity after etching it. Those OMC nanofibers therefore exhibited a very large surface area and a high pore volume of 2486 m2/g and 2.06 cm3/g, respectively. Due to their extremely high porosity values, those fibers were successfully applied as sulfur host and electrode material in lithium-sulfur batteries. The fifth and last part focuses on the synthesis of spherical mesoporous carbon nanoparticles. Therefore the triconstituent coassembly was applied on a silica template with spherical pores, which was derived from the opal structure of colloidal crystals made from 400 nm PMMA spheres. The spherical ordered mesoporous carbon nanoparticles feature extremely high inner porosity of 2.32 cm3/g and 2445 m2/g, respectively They were successfully applied as cathode material in Li-S batteries, where they showed high reversible capacity up to 1200 mAh/g and good cycle efficiency. The final product consists of spherical mesoporous carbon particles with a diameter of around 300 nm and 2D-hexagonal porosity. The particles could be completely separated by sonification to form stable colloidal suspensions. This could be the base for further applications such drug delivery.

Bone integration and biocompatibility of a new bioresorbable polymer for screw augmentation in the osteosynthesis of osteoporotic cancellous bone: The surgical treatment of an osteoporosis-associated fracture is a clinically relevant problem, which yet has no satisfactory solution. The fixation of conventional implants is limited because of the reduced bone density in osteoporotic bones. To ensure stable fixation compound osteosynthesis has been used since the 1950s. Polymethylmethacrylate (PMMA) is the most commonly used bone cement in reconstructive medicine because of its excellent mechanical properties. However, compound osteosynthesis also has some disadvantages. The local exothermic polymerization as well as the release of toxic residual monomers can cause damage to the surrounding tissue. PMMA is also not resorbable, and therefore surgeries using PMMA are irreversible. An ideal absorbable bone cement must meet many biochemical requirements and also provide sufficient mechanical stability. Two critical requirements are long-term biocompatibility, and an absorption rate that corresponds with the reestablishment of the physiologic bone stability. The aim of this study was to investigate different variations of a new resorbable bone cement developed on an alkylene bis(dilactoyl)-methacrylate basis in terms of long-term biocompatibility, degradation and mechanical reinforcement in a sheep model. Further, the suitability of ovarectomized sheep as osteoporotic large animal model was verified for investigation of biomaterial. In this study osteoporosis was generated in sheep by an ovarectomy followed by 6 months of glucocorticoid injections. The control group received no treatment. Two screws were implanted in the cancellous bone in the distal femur and proximal tibia in both groups. The screws were fixed in the bones with variations of the new bone cement. In each group, three screw fixation techniques were investigated: augmented with the new polymers, augmented with PMMA, or not augmented. The ovarectomized sheep were sacrificed after eight weeks (short-term group). The control sheep (long-term group) were sacrificed after six months. Histology results confirmed the biocompatibility of the non-augmented screws as well as the screws augmented with PMMA in both the short- and long-term group. Histology of the cancellous bone showed physiologic remodeling zones. The new polymers were homogenous after eight weeks, with no signs of degradation. The polymer was well distributed in the cancellous bone, but there were no signs of osseous integration of the cement. Only a small number of inflammatory cells were present. However, a significant inflammatory response with macrophages, giant cells and erythrocytes was observed six months after implantation. Massive osteolysis was seen and in some cases so severe that the screw was loose. The degradation kinetics of the new polymers were unsatifactory, because there was no decrease in the volume of the applied bone cement after six months. There is no definitive answer as to what caused the foreign body reaction. Most likely several factors played a role, such as cytotoxicity of the degradation products, particles were broken off and the increased osmotic pressure within the implantation site. The inflammatory reaction and the degree of osteolysis depended without a doubt on the concentration of the polymer. The macroscopic and histologic changes in the osseous implantation site were consistent with the biomechanical results. The mechanical strength of the screws fixation of the new polymers measured by pullout force was significantly less at both eight weeks and six months compared to the screws in the control group. The screws fixed with the new polymer lacked osseous integration and also had poor biocompatibility. Therefore, the new polymers do not meet the requirements for clinical use. The use of ovarectomized sheep treated with glucocorticoids proved to be a suitable animal model for investigating biomaterials in osteoporosic bone. The density of the cancellous bone in the extremities was significantly decreased, compared to the control animals.

Die Anwendung der Einzelmolekülspektroskopie auf poröse Festkörper wird erstmals in dieser Arbeit beschrieben. Um diese relativ neue Methode auf die Untersuchung von Farbstoffen in porösen Festkörpern anzuwenden, wurde ein konfokales Mikroskop so umgebaut, daß es zur Detektion und Spektroskopie einzelner Moleküle einsatzfähig ist. Dafür wurden verschiedene optische Detektionssysteme aufgebaut, um alle im Fluoreszenzlicht enthaltenen Informationen zu erhalten. Mit einer Avalanche Photodiode wurde die Empfindlichkeit des Mikroskops auf die Detektion einzelner Lichtquanten gesteigert. Mit einem gepulsten Laser wurde der ZeitbereichObwohl die Einzelmolekülspektroskopie im Vordergrund der Arbeit steht, sind auch einige interessante Beobachtungen an porösen Materialien mit vielen Farbstoffmolekülen (Ensemblemessungen) durchgeführt worden. Aufgrund des hohen dreidimensionalen Auflösungsvermögen des konfokalen Mikroskopes war es möglich, auch an nur wenige Mikrometer großen Kristallen ortsaufgelöste Untersuchungen durchzuführen. Bisher war es oft nicht möglich, zwischen Oberflächeneffekten und Eigenschaften, die in der Porenstruktur hervorgerufen werden, zu unterscheiden. Untersuchungen mit vielen Farbstoffmolekülen (Ensemblemessungen) zeigten, daß auch scheinbar perfekte Kristalle im Inneren oft unregelmäßig aufgebaut sind. So wurde eine Methode entwickelt, um Defektstrukturen in Kristallen mit Fluoreszenzfarbstoff anzufärben und dreidimensional mit dem konfokalen Mikroskop darzustellen. Große kalzinierte MFI Kristalle besitzen Defektstrukturen, die sich im Inneren entlang der langen Kristallachse ausbreiten. Darüber hinaus konnte gezeigt werden, daß scheinbar homogen mit Farbstoff beladene Kristalle oft eine sehr ungleichmäßige Farbstoffverteilung besitzen. Auch Kristalle, die schon während der Synthese mit Farbstoff beladen werden, sind oft nicht gleichmäßig beladen. Dreidimensionale Fluoreszenzbilder von großen und regelmäßig aufgebauten AlPO4-5 Kristallen, die mit dem Farbstoff DCM beladen wurden, zeigten verschiedene geordnete und ungeordnete Strukturen. Durch die Analyse der Polarisation kann die Orientierung der Farbstoffmoleküle untersucht werden. Untersuchungen an verschieden großen Oxazin Farbstoffen, die während der Synthese in AlPO4-5 eingebaut wurden, zeigten, daß die Ausrichtung entlang der Porenrichtung mit steigender Molekülgröße abnimmt. Das kleine Oxazin 1 ist noch relativ gut orientiert, während das große Oxazin 750 ohne Vorzugsrichtung eingebaut wird. In verschiedenen M41S Materialien wurde die Diffusion von Farbstoff untersucht. Fluoreszenzbilder von M41S Monolithen zeigten das Eindiffundieren verschiedener Farbstoffe in den Festkörper. Über die zeitabhängige Analyse der Eindringtiefe konnten dadurch die Diffusionskonstanten ermittelt werden. Es zeigte sich, daß die Diffusion jeweils bei geladenen Molekülen, größeren Molekülen und bei kalziniertem Monolithen verlangsamt wird. Die Untersuchung des Diffusionsverhaltens in einer M41S Nadel zeigte eine etwa doppelt so schnelle Diffusion quer zur Nadel. Dies steht in Übereinstimmung zu elektronenmikroskopischen Bildern, die zeigen, daß die Nadeln aus zirkularen Poren besteht, die quer zur Nadelrichtung orientiert sind. Im Verlauf dieser Arbeit wurden erstmals einzelne Farbstoffmoleküle innerhalb von porösen Festkörpern detektiert. Im Vergleich zu Referenzproben, bei denen der Farbstoff in einer dünnen Polymerschicht eingebettet wird, ist das Signal zu Untergrund Verhältnis der Einzelmoleküluntersuchungen in den porösen Festkörpern etwas geringer. Auch an der Photostabilität der Fluoreszenzfarbstoffe konnte durch die Einlagerung in die Porenstrukturen keine Verbesserung beobachtet werden. Die Moleküle können nicht nur detektiert, sondern auch spektroskopiert werden. Dabei konnten durch die Analyse der Fluoreszenz verschiedene Parameter bestimmt werden, wie folgende Tabelle zeigt: der Detektion bis hinab in den Nanosekundenbereich erweitert. Durch den Einbau einer Lambda-Halbe Platte wurde die Polarisation des Laserlichtes beeinflußt, um die Orientierung eines einzelnen Moleküls zu bestimmen. Schließlich wurde durch den Einsatz eines Prismas und einer empfindlichen CCD-Kamera die spektrale Aufspaltung ermöglicht, um damit die Fluoreszenzspektren zu bestimmen. Mit allen Experimenten war es nicht nur möglich statische Eigenschaften der einzelnen Fluoreszenzfarbstoffe zu bestimmen, sondern auch deren dynamische Veränderungen. Eine der wichtigsten Anforderungen an organische Farbstoffmoleküle für Einzelmolekülspektroskopie ist die Photostabilität. Um geeignete Farbstoff für den Einbau in die Porenstrukturen zu erhalten, wurden die Photostabilitäten verschiedener Farbstoffe untersucht. Dazu wurden von einigen ausgewählten Farbstoffen die detektierbaren Fluoreszenzphotonen gezählt. Es stellte sich heraus, daß das Farbstoffmolekül TDI in einer dünnern PMMA Schicht eine außergewöhnlich hohe Photostabilität besitzt. Einige TDI-Molekülen emittieren sogar 10 11 Fluoreszenzphotonen bis zum irreversiblen Photobleichen. Zum anderen wurde für sehr instabile Farbstoffmoleküle eine Methode entwickelt, um durch Bleichexperimente an einem Ensemble von Molekülen mit dem konfokalen Mikroskop die Anzahl der emittierten Fluoreszenzphotonen zu ermitteln. Für den Einbau in poröse Festkörper wurden daraufhin einige Oxazinfarbstoffe und das in biologischen Untersuchungen häufig verwendete Cy5 ausgewählt. Diese Farbstoffe können im roten Spektralbereich anreget werden und besitzen mit etwa 10 7 emittierten Fluoreszenzphotonen eine relativ gute Photostabilität. Als Porenstruktur wurden besonders zwei Materialien untersucht. Die Porenstruktur AFI, die im Material AlPO4-5 vorkommt, besitzt eindimensionale Kanäle, die hexagonal wie in einer Bienenwabe angeordnet sind. Von diesem Material können auch regelmäßige Kristalle hergestellt werden, die bis zu einem Millimeter lang sind. Leider sind die Poren des AlPO4-5 mit 0,73 nm Innendurchmesser sehr eng. Alle geeigneten Fluoreszenzfarbstoffe sind etwas größer und werden daher in mehr oder weniger großen Deformationen in dem Kristall eingelagert. Größere Poren besitzen die mesoporösen M41S Materialien. In diese passen alle Farbstoffe ohne Deformation hinein. Jedoch ist die Kristallgröße der M41S Materialien auf wenige µm beschränkt. Mit der Methode der homogenen Fällung können die bisher größten hexagonal geordneten MCM-41 Kristalle hergestellt werden. Zentimeter große hexagonale M41S Festkörper (Monolithe), die durch eine Synthese mit einem Flüssigkristall hergestellt werden, verlieren, wie hier gezeigt wird, während der Synthese ihre eindimensionale Ausrichtung der Poren.Beobachtete Eigenschaft des Lichtes Information aus statischen Bestimmungen Information aus zeitabhängigen Bestimmungen Intensität immer Notwendig Raten (Singulett, Triplett, etc.) Ort Position Diffusion, Transport Polarisation Orientierung Drehung, Rotation Energie Fluoreszenzspektren spektrale Diffusion Diese verschiedenen Untersuchungsmöglichkeiten wurden aufgebaut und an einer Referenzprobe (TDI in PMMA) getestet. Für die Datenanalyse konnte zum Teil auf Methoden in der Literatur zurückgegriffen werden. Es wurde darauf geachtet, daß immer eine Fehlerabschätzung oder eine Simulation durchgeführt wurde, damit die Ergebnisse sinnvoll interpretiert werden konnten. Oft konnten schon an der Referenzprobe (TDI in PMMA) sehr interessante Ergebnisse erhalten werden. So wurden z.B. neben der extrem hohen Photostabilität zwei verschiedene Populationen der Triplettlebensdauer gemessen. Die Position eines einzelnen TDI Moleküls konnte durch die Detektion vieler Photonen auf besser als 1 nm bestimmt werden. Die Analyse von zeitabhängigen Orientierungswinkeln deutet darauf hin, daß ein TDI Molekül in PMMA noch eine sehr geringe Wackelbewegung (~1°) ausführen kann. Bei der Analyse mehrerer 10000 Fluoreszenzspektren von einem TDI Molekül konnten spontane Änderungen der Fluoreszenzwellenlänge und der Schwingungskopplung beobachtet werden. Obwohl die Messungen in den Porenstrukturen aufgrund der geringeren Photostabilität nicht so präzise Ergebnisse liefern, konnten auch hier interessante Beobachtungen gemacht werden. Durch die Analyse der Orientierungswinkel vieler individueller Farbstoffmoleküle konnte gezeigt werden, daß die einzelnen Oxazinfarbstoffe in AlPO4-5 eine gaußförmige Verteilungsfunktion bezüglich ihres Tiltwinkels zur Porenrichtung aufweisen. Die zuvor erwähnten Messungen an einem Ensemble von Molekülen können die Form der Verteilungsfunktion nicht bestimmen. Aufgrund der Kenntnis einer gaußförmige Verteilungsfunktion kann auf ein statistisches Einbauverhalten der Farbstoffmoleküle in Defektstrukturen während der Synthese geschlossen werden. Auch in einem MCM-41 Kristall, dessen große Poren jeden beliebigen Einbauwinkel des Farbstoffes Cy5 erlauben würden, wird eine bevorzugte Orientierung beobachtet. Der Orientierungswinkel zur Porenrichtung zeigt auch hier eine gaußförmige Verteilungsfunktion. Interessanterweise wird bei der frontalen Ansicht auf die hexagonale Struktur (entlang der Bienenwabenstruktur) eine bevorzugte Orientierung auf die Flächen des Sechsecks beobachtet. Eine Ensemblemessung kann unmöglich diese bevorzugte Orientierung detektieren. Neben diesem statischen Verhalten zeigen einige wenige Moleküle auch eine Änderung der Molekülorientierung. Zwei individuelle Oxazin 1 Moleküle änderten ihre Orientierung in AlPO4-5 während der Messung spontan. Im Vergleich zu den anderen Oxazin 1 Molekülen besaßen diese beiden einen ungewöhnlich großen Orientierungswinkel gegen die Porenrichtung. Vermutlich wird die Bewegung durch einen größeren Defekt der Porenstruktur ermöglicht. Ein TDI Molekül im Inneren eines M41S Monolithen zeigte sogar eine mehrfache Drehung zwischen 3 verschiedenen Orientierungen.Eine Dynamik bezüglich des Ortes zeigten einzelne TDI Moleküle im M41S Monolith. Aufgrund der starken hydrophoben Eigenschaften des TDI kann davon ausgegangen werden, daß sich der Farbstoff immer noch im Inneren der Mizelle des Flüssigkristalls befindet, aus dem der Festkörper synthetisiert wurde. Die Diffusionsbewegung kann durch eine Serie von Fluoreszenzbilden mit dem konfokalen Mikroskop direkt verfolgt werden. Entgegen der erwarteten eindimensionalen Diffusion, die die hexagonale Struktur des Monolithen eigentlich erwarten läßt, wird eine isotrope Diffusion ohne Vorzugsrichtung beobachtet (D ~ 0,04 µm 2 /s). Im reinen Flüssigkristall dagegen ist die eindimensionale Diffusion vorhanden. Vermutlich werden die eindimensionalen Poren bei der Synthese der festen Silikatwand so stark verknäult, daß auf der beobachteten Längenskala ein Festkörper ohne Vorzugsrichtung entsteht. Auch die viel langsamere Diffusion im Vergleich zum reinen Flüssigkristall (D ~ 2 µm 2 /s) kann über diese Verknäulung der Poren erklärt werden. Schließlich wurden noch Messungen durchgeführt, um simultane Änderungen der Orientierung, Fluoreszenzspektren oder Triplettraten an einem einzelnen Farbstoffmolekül zu beobachten. Besonders die gleichzeitige Detektion von Fluoreszenzspektren und der Orientierung lassen sich experimentell gut durchführen. Zur Interpretation der Ergebnisse muß hier zwischen einer starken und einer schwachen Kopplung zwischen Gast und Wirt unterschieden werden. Bei einer polaren Probe wird eine starke Wechselwirkung zwischen Gast und Wirt erwartet. Diese müßte dazu führen, daß sich Änderungen in der Orientierung auch in geänderten Fluoreszenzspektren und umgekehrt bemerkbar machen. Bei einem geladenen Molekül wie Oxazin 1 wird solch eine starke Kopplung des elektronischen Systems an die polare AlPO4-5 Umgebung erwartet. Eine starke Änderung des Fluoreszenzspektrums könnte daher von einer Umorientierung des Farbstoffes herrühren. Bei den durchgeführten gleichzeitigen Messungen konnte aber nur spektrale Diffusion (±1-20 nm), aber keine gleichzeitige signifikante Umorientierung (>3°) beobachtet werden. Eine Erklärung für dieses Verhalten könnte die Bewegung des Gegenions des Farbstoffmoleküls sein, dessen Lage einen großen Einfluß auf die Fluoreszenzeichenschaften hat. Eine Umorientierung mit gleichzeitiger Detektion der Fluoreszenzspektren konnte jedoch nicht gemessen werden. Beide Ereignisse, Umorientierungen und spektrale Änderungen, konnten an TDI im M41S Monolith detektiert werden. Dabei zeigte sich aber, daß es sich hier um zwei unabhängige Prozesse handelt. Deutliche spektrale Sprünge (> 3 nm) korrelieren nicht mit deutlichen Umorientierungen (~60°). Eine geometrische Änderung des Farbstoffmoleküls oder der näheren Umgebung scheidet daher als Ursache für die spektrale Diffusion aus. Da hier aber eine schwache Wechselwirkung zwischen dem unpolaren TDI und der unpolaren Tensidumgebung vorliegt, werden auch keine starke Änderungen der Fluoreszenzspektren während der Umorientierung erwartet. Die spektrale Diffusion wird hier vermutlich von kleinen diffundierenden Teilchen (z.B. O2 oder Ionen) verursacht, die sich unabhängig von den Farbstoffmolekül bewegen können. Die Methode der Einzelmolekülspektroskopie liefert neue Einblicke in poröse Festkörper. Besonders durch die zeitabhängigen Untersuchungen können Informationen erhalten werden, die zuvor unter dem Mittelwert verborgen blieben. Ein kleiner Teil der Arbeit beschäftigt sich mit der Tieftemperaturfluoreszenz-spektroskopie an dem grün fluoreszierendem Protein (GFP). Dafür wurden der Wildtyp und verschiedene Varianten mit Mutationen in der Umgebung des zentralen Chromophors bei 2 K untersucht. Im Vergleich zur Raumtemperatur zeigten die Spektren bei tiefen Temperaturen deutlich mehr Struktur. Dadurch konnten verschiedene Sub-Zustände in den Varianten identifiziert werden. Bei fast allen Varianten konnten durch intensive Bestrahlung langwellig absorbierende Photoprodukte erzeugt werden, die erst bei etwa 50 bis 100 K wieder zerfallen. Obwohl eine relativ starke Elektron-Phonon-Kopplung beobachtet wird, ist an einigen ausgewählten Stellen auch hochaufgelöste Tieftemperaturspektroskopie wie spektrales Lochbrennen und Fluoreszenzlinienverschmälerung möglich. Durch Temperatur-Ableitungs-Spektroskopie werden an Wildtyp-GFP die Energien und Verteilungsfunktionen der Zerfallsbarrieren der metastabilen Photoprodukte bestimmt. Schließlich wurde durch temperaturabhängige Kurzzeitspektroskopie an Wildtyp-GFP der 'Excited state proton transfer' (ESPT) charakterisiert. Für diesen wird bis etwa 50 K eine thermische Barriere nach Arrhenius mit einer Aktivierungsenergie von ~2,3 kJ/mol gefunden. Unterhalb von etwa 50 K dominiert vermutlich ein Tunnelprozeß.
