报告题目：Nanogold: From Artificial Periodic Table to Soft, Stretchable and Wearable Optoelectronics
报 告人：Prof. Wenlong Cheng (程文龙)
Monash University, Australia
Gold is a precious metal that has been used for coinage, jewelry, and other arts throughout recorded history. The world consumption of new gold produced is about 50% in jewelry, 40% in investments, and 10% in industry. Nanogold represents the earliest record of human nanotechnology, which wasn’t understood until about a century ago. With the birth of nanoscience and nanotechnology, gold chemistry flourishes significantly. This enables shaping gold at the nanoscale with well-defined size and shape, forming so-called “artificial periodic table”. I will focus on discussion how nanogold can be used to design novel 2D self-assembled plasmonic nanomaterials as well as soft highly stretchable sensors and energy devices.
Wenlong Cheng is a professor and director of research in the Department of Chemical Engineering at Monash University, Australia. He is also an Ambassador Tech Fellow in Melbourne Centre for Nanofabrication. He earned his PhD from Chinese Academy of Sciences in 2005 and his BS from Jilin University, China in 1999. He held positions in the Max Planck Institute of Microstructure Physics and the Department of Biological and Environmental Engineering of Cornell University before joining the Monash University in 2010. His research interest lies at the Nano-Bio Interface, particularly self-assembly of 2D plasmonic nanomaterials, DNA nanotechnology, electronic skins and stretchable energy deivces. He has published >130 papers including 3 in Nature Nanotech, 1 in Nature Mater, 1 in Nature Comm and 1 in Nature Protocol. He is currently the editor for the Elsevier journal – Inorganic Chemistry Communications, and the editorial board members for a few journals including Cell press journal – iScience.
