报告人简介：
Dr. Benjamin S. Hsiao is a Distinguished Professor in Chemistry at Stony Brook University. He received his B.S. degree from National Taiwan University in 1980, Ph.D. from University of Connecticut, and post-doctorate training at University of Massachusetts. He joined DuPont Company as a staff scientist and spent 8 years in R&D before coming to Stony Brook University. He served as Chair of Chemistry Department and Vice President for Research at Stony Brook University. Currently, Hsiao is a Founding Co-Director of Innovative Global Energy Solutions Center, aiming to prototype ‘sustainability for off-grid communities of tomorrow’, using the Turkana Basin Institute in northern Kenya as a living laboratory. He is also the Founding Director of Center for Advanced Technology in Integrated Electric Energy Systems, with the mission to enhance the development and integration of advanced technologies for the nexus of food, energy and water.
Hsiao’s current research interests are mainly focused on the development of sustainable nanomaterials from underutilized biomasses for water purification. He published over 500 peer-reviewed scientific papers, 49 reviews and chapters in books and encyclopedias, 228 conference proceedings, obtained 36 issued patents (including 26 US patents) and 21 pending patent applications, and edited 2 books. He was elected as Fellow of American Association for the Advancement of Science (AAAS), Fellow of American Chemical Society, Fellow of American Physical Society, Fellow of Materials Research Society, Fellow of National Academy of Inventors, AAAS-Lemelson Invention Ambassador, Honorary Professor from University of Queensland in Australia, Chang-Jiang Scholar from Education Ministry of China, Co-operative Research Award from Division of Polymeric Materials Science and Engineering of American Chemical Society, NSF Special Creativity Award and DuPont Young Faculty Award.
报告摘要：
Nanoscale cellulose fibrous materials obtained from the chemical treatment of biomass are very effective agents for the removal of toxic species from water, including heavy metal ions. Our team at Stony Brook University has developed a simple, inexpensive and environmentally friendly approach to preparing nanostructured cellulose fibers for water purification, based on a nitro-oxidation reaction carried out on biomasses of diverse origins. There are three key advantages of the nitro-oxidation method. First, the method greatly reduces the consumption of chemicals, energy and water. Second, the processing effluent can be efficaciously neutralised to produce plant fertilisers. Third, the method is effective to extract nanostructured cellulose from underutilised raw biomass such as agriculture waste. The resulting nanocellulose is proven to be an efficient water purification material (membrane or adsorbent) that can treat a wide range of water pollution problems. The demonstrated technology represents an innovative means to enhance the nexus of food, energy, and water systems, and has many far-reaching impacts to improve quality of life.
