Chang Group attends the 58th Int. Conference on Electron, Ion, and Photon Beam Technology and Nanofabrication in Washington, DC. Allan gave a well-received invited talk on 3D nanolithography using particle scattering. Abhijeet gave a talk on mechanical properties of nano-springs, and Joong Hee had an invited poster for his work on colloidal fabrication of 3D nanostructures. Zhiting and John also made poster presentations on their work on wicking and fabrication of hierarchical nanostructures, respectively.
