DESCRIPTION:Dr. Eric Hoek will begin this talk with a brief overview of pa
 st and ongoing food-energy-water nexus research in the UCLA Nanomaterials
 \, Membrane & Electrochemical Technologies Research (NanoMETeR) Lab\, inc
 luding a few attempts to translate basic research discoveries into commer
 cial innovations. Then\, I will present new results––both experimental an
 d theoretical––on a new class of fully thermoset reverse osmosis (RO) mem
 brane materials designed to operate at extreme temperatures and pressures
 . Conventional RO membranes comprise an ultra-thin\, microporous cross-li
 nked (thermoset) polyamide (PA) film formed over a mesoporous polysulfone
  (PSU) (thermoplastic) support membrane\, which is cast over a macroporou
 s nonwoven polyester fabric. The thermoplastic PSU supports experience pe
 rmanent deformation and damage via plastic creep when exposed to high app
 lied pressure (>50 bar) and/or feed solution temperature (>30 ºC)\, while
  the thermoset PA layer physically compacts under pressure\, but recovers
  its original free volume upon pressure relief. We have employed advanced
  modeling methods such as density functional theory\, molecular dynamic s
 imulations and a novel “material point method” along with traditional wet
 -testing experiments and ex situ light and electron microscopy plus novel
  X-ray computed tomography (CT) and focused ion beam-electron microscopy 
 CT to elucidate the fundamental mechanical properties and resulting perfo
 rmance characteristics of conventional and fully thermoset RO membranes. 
 These new high-pressure/-temperature tolerant RO membranes can serve appl
 ications that have long been exclusively in the domain of thermal technol
 ogies. If scalable\, RO membrane-based solutions could be half the capita
 l cost and half the energy demand of traditional thermal-based separation
  processes.\n\nSpeaker:\nEric Hoek\, PhD\n\nAdmission:\nFree\n\nDetails U
