How could something only billionths of a meter thick defend against water, dirt, wear, and even bacteria? Working at the nanoscale, scientists and engineers, like Jay Guo are creating protective nanoscale coatings and layers. These surfaces have applications in energy, electronics, medicine, and could even be used to make a plane invisible.
The video featured above, Nanotech at the Surface, is part of a series of videos about Nanotechnology produced by NBC Learn, in partnership with the National Science Foundation. Called, "Nanotechnology: Super Small Science," this six-part series shows viewers how atoms and molecules that are thousands of times smaller than the width of a human hair can be used as building blocks to create future technology.[watch all the videos in the series]
Prof. Jay Guo is a world-renowned researcher who has made significant contributions to a wide variety of areas, including: photonic devices and sensors, organic and hybrid photovoltaics, nanofluidics, ultrasound and photoacoustic detectors, and nanofabrication technologies. He and his research group are responsible for innovations such as highly compact terahertz detectors, decorative photovoltaic cells, a new transparent electrode for large, flexible OLED and display screens, roll-to-roll nanoimprint lithography, a photoacoustic lens to generate high amplitude ultrasound for focused therapy, and a nanostructured optical film to boost LCD efficiency. His research has attracted wide media coverage, and companies around the world have developed commercial products based on his research.
