Nanoscience & Nanotechnology
Nanotechnology is to understand and control matters at dimensions smaller than 100 nanometers. At this dimension, the physical, chemical, and biological properties of materials differ significantly from the properties of bulk matter, where unique phenomena enable novel applications. Research in nanotechnology involves fabricating/synthesizing, characterizing, modeling, and manipulating matter at this nanometer scale. Nanotechnology is a rich, dynamic, and expanding research area in the Department of Physics and Astronomy. Current research activities include nanomaterial fabrication/synthesis, nano-optics, nano-magnet, spintronic, chemical and biology sensing, renewable energy applications, medical imaging, disease treatment and drug delivery.

Surfaces and Interfaces
The Dennis group uses a variety of computer simulation techniques to investigate the interaction of electromagnetic radiation on nanomaterials and metamaterials. With Dr. Yiping Zhao we have recently initiated a new effort to simulate the deposition of nanostructured materials.
