Abstract:
Nanorods are nanoscale in diameter. Why is the diameter nano? The first part of this presentation covers the proposal of a new concept of multiple-layer surface diffusion, closed-form theories of nanorod diameter based on the new concept, and theory-guided designs and experimental realizations of smallest and well-separated metallic nanorods using physical vapor deposition. The closed-form theories explain why nanorod diameter is nano, and provide a framework for science-based design and synthesis of nanorods.
Nanorods are nanoscale in diameter, again. Does the nanoscale diameter enable any technologies? The second part of this presentation focuses on the translation of nanorod science into a metallic glue technology, and the commercialization of this technology. Taking advantages of the small and well-separated metallic nanorods, a new metallic glue is invented and it connects two solids at room temperature, in air, and under small pressure. Once the gluing process completes in seconds, the glue remains solid for operations at high temperature and pressure. This metallic glue technology has attracted about 200 news reports (https://engineering.unt.edu/people/hanchen-huang/news-reports) in the first few months of 2016, and has been featured as one of “The 20 Coolest Inventions of 2016” by the Interesting Engineering magazine. Commercialization of this technology through MesoGlue Inc, is underway (www.MesoGlue.com).
