Research Areas

Nanoscience, Nanoparticles, Synthesis, Catalysis, Optics

Nanoparticles: Small Wanders, Endless Frontiers

Our research focuses on fundamental science and engineering questions motivated by the creation of materials on the nanometer scale (1 nm=10-9 m). Our research themes include the synthesis, characterization, and applications of nanoparticles (typically 1-100 nm in size). We are developing chemical methods for synthesizing well defined nanoparticles, including atomically precise nanoclusters, shape- and size-controlled nanocrystals, hybrid nano-architectures, and inorganic/polymer nanocomposites. In-depth characterizations of the physical and chemical properties of nanoparticles and self-assembled nanomaterials are carried out with microscopy and spectroscopy techniques, such as electron microscopy, atomic force microscopy, X-ray crystallography, steady-state and ultrafast spectroscopies, etc. We also develop applications of nanoparticles in areas of catalysis, optics, chemo- and bio-sensing, and photovoltaics, etc.
