Podcasts about superhydrophobic

De biomarkers in zweet kunnen artsen steeds meer vertellen over onze gezondheid. Alleen niet al het zweet kon tot nu toe worden gemeten.  Dat wat je ziet ontstaan op de huid na een paar stevige sportoefeningen is geen probleem voor bestaande sensoren, maar er is nog een ander type zweet. De variant die als waterdamp de huid verlaat. Hiervan verlaat een veel kleinere hoeveelheid het lichaam, ook als je niet aan het sporten bent.   Deze vorm van zweet geeft volgens onderzoekers belangrijke kennis over de conditie van de huid en onderliggende processen in het lichaam. Denk aan de status van eczeem en wondherstel, maar zelfs ook pijn en angst.   Om dit type zweet ook te kunnen meten, hebben onderzoekers een nieuwe sensor ontwikkeld, die als een soort pleister op de huid te plakken is. De sensor bestaat uit een super absorberende hydrogel op een poreus materiaal dat tussen twee laagjes waterafstotende stof gesandwicht wordt. Zo kan zweetdamp makkelijk de sensor bereiken, maar wordt deze niet beïnvloed door zweetdruppels.   Eerste testen met mensen zien er volgens de onderzoekers goed uit. Wat ze er precies allemaal mee willen gaan meten moet nog blijken.

From cool fabrics, to melting ice and recycling e-waste. How can a fabric let air through, but keep water out? Clothing that is breathable, water resistant and thermally efficient hits the sweet spot of a super fabric. Making clothes more efficient at cooling but also self cleaning can reduce our reliance on air conditioning. Using electricity and some polymers we can spin up some new cool clothing fabrics. Melting ice in your frozen over freezer can be made easier with biphillic materials. Materials that both hate and love water at the same time, can help melt ice and make heater exchangers more efficient. Recycling e-waste can be tricky, but what if we could use the by-products to  make new, stronger coatings for steel? Turning e-waste into a steel boosting coating. Rumana Hossain, Veena Sahajwalla.

The award-winning LotusFlo™ superhydrophobic coating is solving a major problem in offshore oil drilling. Substances often clog pipes, slowing or stopping the flow of oil. This innovative coating applied through a unique plasma process keeps substances from adhering to pipe surfaces. Better flow makes recovering petroleum for fuel and other products more cost-effective, which is a win for consumers too. But that’s not the only perk, LotusFlo is also better for the environment, cutting out the need for harsh chemicals that pollute the ocean. R&D Magazine recently recognized LotusFlo as one of the 100 most significant innovations of 2019. Find out why! Plus, an SwRI engineer shares his breakthrough moment bringing about cleaner engines and cleaner air. In Ask Us Anything, we’re tackling the popular tech topic, machine learning. Listen and learn from the people shaping our world through science, engineering, research and technology.

In this Tech Pathways episode of Stories from the NNI, Dr. Lisa Friedersdorf (Director of the NNCO) speaks with Mark Shaw (CEO of UltraTech International, Inc.) about the materials his company is developing that use nanotechnology, including a superhydrophobic coating that repels liquids. Mark also shares his experience taking an invention to the marketplace, discusses his company’s efforts in nanotechnology education, and describes how the NNI has been fostering the transfer of new nanotechnologies into commercial products.

Julia Yeomans will talk about fluids and flows all around us: from superhydrophobic surfaces and how animals and plants keep dry, to bouncing droplets and balloons.

This video introduces the concept of surface tension, and shows how roughness can make a surface superhydrophobic or superhydrophilic. The Wenzel and Cassie-Baxter models are explained.
