Abstract:
Significant advances in colloidal synthesis made in the past two decades have enabled the preparation of high quality nanoparticles with well-controlled sizes, shapes, and compositions. It has recently been realized that such nanoparticles can be utilized as 'artificial atoms' for building new materials. The controlled clustering of nanoparticle building blocks into defined geometric arrangements opens a new research area in materials science. In this presentation, I will introduce several strategies for the creation and surface modification of colloidal nanoparticle clusters, demonstrate the new collective properties resulting from their secondary structures, and highlight their many important technological applications ranging from bioseparation, biosensor, photocatalysis and energy storage.
Biography:
Dr. Zhenda Lu received his BS and MS Degree in Chemistry at Nanjing University in 2004 and 2007, respectively. Then he got his PhD in Chemistry at University of California, Riverside in 2012 under the supervision of prof. Yadong Yin. His PhD research focuses on the synthesis, surface modification, self-assembly of nanoparticles, and their bioanalytical and catalytic applications. Now he is working as a postdoctoral fellow at Stanford University, under the supervision of Prof. Yi Cui. His current research is nanostructured Si anodes for Lithium ion battery. He has received several prestigious awards including: Silver Medal of Graduate Student Award (Material Research Society, 2012), Chinese Government Award for Outstanding Students Abroad (2012). He has published over 40 papers in prestigious journals (Nature Nanotech., Angew. Chem. Int. Ed., Nano Lett., Anal. Chem., etc.), with H index 22. He reviewed more than 90 papers for over 20 scientific journals, including Nano Lett., Energy Environ. Sci., Anal. Chem., Chem. Commun., J. Mater. Chem., Nanoscale, etc.
