  1. Breakthrough Nanofibrous Membranes for Energy-Saving Water PurificationBenjamin S. Hsiao, SUNY at Stony Brook University, DMR 1019370 This EAGER project aims to investigate breakthrough concepts on a new format of thin-film nanofibrous composite (TFNC) polymeric membranes containing directed water channels for high-flux water purification. Such nanofibrous membranes, radically different from conventional polymer membranes, are untested but represent a potentially transformative technology for significant energy-saving and cost-effective water purification applications. Preliminary experiments on the hierarchical structure design and assembly of the new TFNC membranes for microfiltration (MF) and ultrafiltration (UF) have already exhibited 2-5 times higher flux than those of the best commercial membranes without losing the comparable high rejection ratio. The TFNC structure can serve as a platform to develop highly permeable membranes for desalination processes (e.g. reverse osmosis (RO) and forward osmosis (FO)). Ultra-fine polysaccharide nanofibers (diameter 5-20 nm) have been prepared and employed as the means to carry water channel in the barrier layer

  2. Breakthrough Nanofibrous Membranes for Energy-Saving Water PurificationBenjamin S. Hsiao, SUNY at Stony Brook University, DMR 1019370 The broader impacts of this research are as follows. The success of the proposed research will bring significant benefits to society by providing practical means for energy saving water purification. The proposed high-flux technology on water purification can immediately reap benefits on the quality-of-life and health concerns. For example, there are increasing concerns on the presence of emerging contaminants in drinking water sources all over the world. These challenges offer us new opportunities to develop novel and innovative energy saving membrane products as well as improved water processing technologies. In 2010, eight high school students have participated in this research project, where four have won finalist (2) and semi-finalist (2) status with related research projects in the Siemens-Westinghouse Competition.
