ITRI-Rosenfeld Seminar: Exploring the Molecular-Level Structure and Property Relationship of Membrane for Energy and Water Production
Both water scarcity and energy shortage are becoming top global challenges in the 21st century. Membrane technology has an important role to play in solving the water and energy problems. Different membrane processes have been proposed for the generation of clean water and/or energy, including nanofiltration (NF), reverse osmosis (RO), forward osmosis (FO) and reverse electrodialysis (RED). Membrane properties can significantly influence the efficiency of the different membrane processes. However, a fundamental understanding of how membrane structure can influence membrane properties is lack. A more detailed molecular level understanding of membrane structure and property relationship is critical for the designing of membranes with better selectivity. This talk will address the design of new ion exchange membranes and osmotic-driven membranes for reverse electrodialysis (RED) and pressure-retarded osmosis (PRO) processes, respectively, as well as propose a new way of exploring the molecular-level transport of thin-film composite (TFC) membranes by using advanced electron microscopy.
PhD Candidate, Georgia Institute of Technology
Xin Tong is a Ph.D. candidate in the School of Civil and Environmental Engineering at Georgia Tech. Xin’s current research aims to develop novel membranes for reverse electrodialysis (RED) and pressure-retarded osmosis (PRO) to harvest salinity gradient energy. During his Ph.D. study, Xin has authored and co-authored eight peer-reviewed papers on environmental engineering and membrane technology.
