| 报告介绍 | 报告摘要：
Graphite oxide sheets, now called graphene oxide (GO), are made by exfoliation of graphite using century-old chemical reactions. Interest in this old material has resurged with the rapid development of graphene since 2004, as GO is considered to be a promising precursor for bulk production of graphene. Apart from making graphene, GO itself also has many intriguing properties. For example, GO can be viewed as a two-dimensional (2D) soft material such as polymer, highly anisotropic colloid that can form liquid crystals, membrane, or 2D surfactant. In this talk, some curiosity driven discoveries will be shared such as the use of GO as surfactant to process insoluble materials in water. GO sheets are also 2D building blocks to construct massive arrays of 2D nanofluidic channels with high ionic conductivity. A few problems associated with the manufacturing and processing of GO and its graphene product will be discussed, such as the difficulties of imaging these single atomic layers and their ease of aggregation during processing. Strategies and solutions to address these problems will be introduced.
报告人简介：
Jiaxing Huang received his B.S. degree in Chemical Physics from University of Science and Technology of China (USTC) in 2000, Ph.D. in chemistry from the University of California, Los Angeles (UCLA) in 2004, and became a Miller Research Fellow at the University of California, Berkeley before joining Northwestern as an Assistant Professor of Materials Science and Engineering at Northwestern University in 2007. He was named the Morris E. Fine Junior Professor in Materials and Manufacturing in 2011-2013 and was promoted to Associate Professor with tenure in 2013. His main research interest is in the general area of material chemistry, processing and manufacturing. Some of the examples include 2D soft materials, organic nanocrystals and metal nanostructures. He is also interested the application of these materials in energy and sustainability, as well as using them as a platform for materials education. He has been a recipient of the IUPAC Young Chemists Prize, the NSF CAREER Award, the Alfred P. Sloan Research Fellowship, the Outstanding Young Manufacturing Engineer Award from the Society of Manufacturing Engineers and the Guggenheim Fellowship. |
