2016年6月29日下午，美国阿肯色大学Ranil Wickramasinghe教授在welcome菠菜导航网望江校区化工学院245室分别做了题目为“Multifunctional Membrane for Advanced Separations”的精彩学术报告。会议由化工学院院长褚良银教授主持、来自welcome菠菜导航网化工学院和化学学院的教师和同学共同参加了此次报告会。

Wickramasinghe教授首先简要介绍了膜科学工程技术中心的基本情况，接着引出了报告会的主要内容——多功能膜，Wickramasinghe教授介绍了两类功能膜，一类是对环境刺激如温度、pH、磁场和离子浓度等变化而变化的响应膜。Wickramasinghe教授分别就磁响应膜和离子浓度响应膜为例详细介绍了该类型的膜的特点和应用。另外一类是能进行催化反应的催化膜。Wickramasinghe教授课题组致力于将膜的表面作为催化反应场所使木质纤维素水解或脱水，与此同时也可将产物进行分。最后，Wickramasinghe教授对磁响应膜、离子浓度响应膜和催化膜的工业应用作了介绍和展望。

在提问环节，Wickramasinghe教授与各位师生就多功能膜用于分离领域进行了深入的交流与讨论，现场氛围融洽，师生们热情高涨。最后，大家以热烈的掌声感谢了Wickramasinghe教授的精彩演讲。

Ranil教授做报告

Ranil Wickramasinghe教授简介：

Professor Ranil Wickramasinghe holds the Ross E Martin Chair in Emerging Technologies in the Ralph E Martin Department of Chemical Engineering at the University of Arkansas. He is the Director of the University of Arkansas Site of the Membrane Science, Engineering and Technology (MAST) Center. The MAST Center is the only National Science Foundation Industry and University Cooperative Research Center that focuses on Membrane Science.

Prof. Ranil obtained his PhD from the University of Minnesota in Chemical Engineering. He worked for the biotechnology Industry in Boston before joining the Department of Chemical Engineering at Colorado State University. In 2011 he joined the University of Arkansas. Prof. Ranil has published over 120 peer reviewed journal articles, several book chapters and is co-editor of a book on responsive membrane and materials. He is active in the American Institute of Chemical Engineers and was the Meeting Program Chair of the 2014 Annual Meeting in San Francisco. He has also served on the Board of Directors of the North American Membrane Society. Prof. Ranil is the meeting co-chair for the International Congress on Membranes and Membrane Processes (ICOM) 2017 to be held 29 July-4 August 2017 in San Francisco.

Prof. Ranil’s research focuses on membrane-based separation processes for purification of pharmaceuticals and biopharmaceuticals, treatment and reuse of water and for the production of biofuels. Typical unit operations include: microfiltration, ultrafiltration, virus filtration, nanofiltration, membrane extraction etc. A current research focus is surface modification of membranes in order to impart unique surface properties. His group is actively developing responsive membranes. These membranes change their physical properties in response to changed environmental conditions. A second research focus is the development of catalytic membranes for biomass hydrolysis by grafting catalytic groups to the membrane surface.
