摘要：
Boron nitride (BN) nanosheets are an important member of two-dimensional (2D) nanomaterials and have a hexagonal structure similar to graphene. Because of its white color, they are also called as “white graphene”. BN nanosheets have many properties distinct to graphene and unique applications not available to graphene. Our current research focuses on synthesis technique, new property exploration and applications on environmental protection and energy storage. This presentation reports our recent research results in BN nanosheets from special mechanical properties, strong resistance to oxidation and protecting metals from oxidation and corrosion, excellent dielectric screening properties, to special surface adsorption ability. I will also present new applications of BN nanosheets including porous BN nanosheets for effective oil-water separation, functionalized BN nanosheet membranes and their fluidic devices, reusable substrates for surface enhanced Raman spectroscopy (SERS), and interlayers for improving cycling life of Li-S batteries.

报告人简介：
Professor Ying Chen is the Alfred Deakin Professor and Chair of Nanotechnology at the Institute of Frontier Materials of Deakin University, Australia. He is well-known and respected internationally for his work in nanomaterials and nanotechnology. His invention of a ball-milling and annealing method for the mass production of nanotubes and nanowires has made a significant impact on the emerging nanotube industry. The team he has put together is a world leader in nanomaterials production and commercialization. His current research is focused on developing different synthetic methods (ball milling and annealing method, chemical/physical vapour deposition, and mechanical alloying) and new applications (energy storage in batteries, capacitors, solar cells and drug delivery) for a variety of nanomaterials including nanotubes (C and BN), nanosheets, nanowires, nanorods, nanoparticles, and nano thin films(graphene).
Professor Ying Chen obtained his University degree from Tsinghua University in Beijing, China and a PhD degree from the University of Paris-Sud, France. He had worked at the Australian National University, Canberra for 15 years before moving to Deakin University in 2009. He has published over 300 publications and is listed by the ISI Web of Knowledge as the top author on two subjects of nanotubes and ball milling. He has contributed to three bestselling books on nanotechnology published by CRC Press. His publications have been cited more than 9000 times over the past 10 years with an H factor of 49. Professor Chen is the Fellow of Institute of Physics, member of American Physics Institute, Materials Research Society, and Australian Materials Union. He has been awarded several prestigious awards, including QEII/ARF fellowships from the Australian Research Council and 1000 talented professorship in 2011. He has been given keynote and invited presentations at international conferences every year.
