Nanomechanics and Nanoengineering Laboratory
Welcome to the Zhu group! Our research addresses basic and applied problems at the intersection of Solid Mechanics and Micro/Nano-technology. We aim to understand mechanical and multiphysical behaviors of nanomaterials through in-situ experiments and explore their device applications based on their unique properties.
