Title: Science and Technology to Secure the Future for Water and Energy
Presenter: Prof Benny Freeman, The University of Texas at Austin
Professor Benny Freeman is the Richard B. Curran Centennial Chair in Engineering at The University of Texas at Austin. He is a professor of Chemical Engineering and has been a faculty member for 28 years. He completed graduate training in Chemical Engineering at the University of California, Berkeley, earning a PhD in 1988. In 1988 and 1989, he was a postdoctoral fellow at the Ecole Supérieure de Physique et de Chimie Industrielles de la Ville de Paris (ESPCI), Laboratoire Physico-Chimie Structurale et Macromoléculaire in Paris, France. Dr. Freeman was a member of the chemical engineering faculty at NC State University from 1989 - 2002, and he has been a professor of chemical engineering at The University of Texas at Austin since 2002. Dr. Freeman's research is in polymer science and engineering and, more specifically, in mass transport of small molecules in solid polymers. His research group focuses on structure/property correlation development for desalination and gas separation membrane materials, new materials for hydrogen separation, natural gas purification, carbon capture, and new materials for improving fouling resistance and permeation performance in liquid separation membranes. He has won a number of awards, including a Fulbright Distinguished Chair (2017), a Distinguished Service Award from the American Chemical Society (ACS) (2015), the Joe J King Professional Engineering Achievement Award from The University of Texas (2013), the American Institute of Chemical Engineers (AIChE) Clarence (Larry) G Gerhold Award (2013), the Society of Plastics Engineers International Award (2013) and the Roy W Tess Award in Coatings from ACS (2012).

Title: Photoelectrochemical CO2 reduction
Presenter: Dr Daniel J. Miller, Lawrence Berkeley National Laboratory
Dr. Miller is interested in the structure/property relationships that govern the transport of small solutes – including gases, ions, and small-molecule organics – through polymeric membranes. These relationships become particularly complex in the presence of solute mixtures, where solute-solute interactions and/or solute-membrane interactions can affect transport, such as in the case of membrane plasticization. Furthermore, understanding interfacial phenomena affecting membrane transport, such as ion sorption/exclusion and foulant deposition, is of interest. Dr. Miller's research in JCAP focuses on the characterization of polymeric membranes for use in electrochemical CO2 reduction cells. These membranes are responsible for permitting charge carrier transport from electrode to electrode while minimizing product crossover that reduces device efficiency. Measurement of ion and CO2 reduction product transport through various membranes forms the cornerstone of Dr. Miller's research program. Commercial and newly-synthesized experimental membranes are characterized. Polymer characteristics – such as charge density, crystallinity, and morphology – are tuned to develop an understanding of how transport is affected.
