2016年6月29日下午，美國阿肯色大學(xué)Ranil Wickramasinghe教授在四川大學(xué)望江校區(qū)beat365245室分別做了題目為“Multifunctional Membrane for Advanced Separations”的精彩學(xué)術(shù)報告。會議由beat365院長褚良銀教授主持、來自四川大學(xué)beat365和化學(xué)學(xué)院的教師和同學(xué)共同參加了此次報告會。
Wickramasinghe教授首先簡要介紹了膜科學(xué)工程技術(shù)中心的基本情況，接著引出了報告會的主要內(nèi)容——多功能膜，Wickramasinghe教授介紹了兩類功能膜，一類是對環(huán)境刺激如溫度、pH、磁場和離子濃度等變化而變化的響應(yīng)膜。Wickramasinghe教授分別就磁響應(yīng)膜和離子濃度響應(yīng)膜為例詳細(xì)介紹了該類型的膜的特點和應(yīng)用。另外一類是能進(jìn)行催化反應(yīng)的催化膜。Wickramasinghe教授課題組致力于將膜的表面作為催化反應(yīng)場所使木質(zhì)纖維素水解或脫水，與此同時也可將產(chǎn)物進(jìn)行分。最后，Wickramasinghe教授對磁響應(yīng)膜、離子濃度響應(yīng)膜和催化膜的工業(yè)應(yīng)用作了介紹和展望。
在提問環(huán)節(jié)，Wickramasinghe教授與各位師生就多功能膜用于分離領(lǐng)域進(jìn)行了深入的交流與討論，現(xiàn)場氛圍融洽，師生們熱情高漲。最后，大家以熱烈的掌聲感謝了Wickramasinghe教授的精彩演講。
Ranil教授做報告
Ranil Wickramasinghe教授簡介：
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.
