DESCRIPTION:Prof. Jiaxing Huang\, Northwestern University (USA) Dep. of Ma
 terials Science and Engineering\nGraphite oxide sheets\, now called graphe
 ne oxide (GO)\, are made by exfoliation of graphite using century-old chem
 ical 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\, G
 O itself also has many intriguing properties. For example\, GO can be view
 ed as a two-dimensional (2D) soft material such as polymer\, highly anisot
 ropic colloid that can form liquid crystals\, membrane\, or 2D surfactant.
 \nIn this talk\, some curiosity driven discoveries will be shared such as 
 the use of GO as surfactant to process insoluble materials in water. GO sh
 eets are also 2D building blocks to construct massive arrays of 2D nanoflu
 idic channels with high ionic conductivity. Next\, a few problems associat
 ed with the manufacturing and processing of GO and its graphene product wi
 ll be discussed\, such as the difficulties of imaging these single atomic 
 layers and their ease of aggregation during processing. Strategies and sol
 utions to address these problems will be introduced. Some applications in 
 photovoltaics and energy storage will be discussed.\nBio: 2013-\nAssociate
