Title ： Unusual Modes of Crystal Growth by Colloidal Methods
Abstract : This talk will start with a general summary of the research directions in our lab. Then, I will focus on the mechanisms of three different systems: (a) the growth of single-crystalline organic domain on poly-crystalline gold seeds; (b) the continuously tuning of Au-Ag interfacial energy by embedding ligand inside metal layers; and (c) the coating of Pd on Au-Ag alloy nanowires that results in metal double helices.

Hongyu Chen obtained his B. Sc. from University of Science and Technology of China (USTC) in
1998. He then moved to Yale University and studied Mn and water oxidation chemistry. After obtaining his Ph.D. degree in 2004, he worked as a post-doctoral fellow in Cornell University on the topic of protein-nanoparticle hybrids. In 2006, he joined the Division of Chemistry and
Biological Chemistry in Nanyang Technological University in Singapore, where he is currently an
Associate Professor. His main research interest is in the development of new synthetic methodologies for nanostructures.
