Improved understanding of transport in concentrated electrolyte solutions has important implications for energy storage, water purification, biological applications, and more. This understanding should ideally persist across length scales: we desire both continuum-level insight into macroscopic concentration and electric potential profiles as well as a molecular-level understanding of the mechanisms governing ion motion. However, the most ubiquitous theory to describe continuum-level electrolyte transport, the Stefan-Maxwell equations, yields transport coefficients which lack clear molecular-level interpretation and cannot be easily computed from molecular simulations.
Hydrogen has long been seen as a possible renewable fuel source, held out of reach for full-scale adoption by production costs and inefficiencies. Researchers in the Weimer Group are working to address this by using solar thermal processing to drive high-temperature chemical reactions that produce hydrogen and carbon monoxide, which can be used to synthesize liquid hydrocarbon fuels.
Eight cross-disciplinary teams working to advance fundamental science in the removal of greenhouse gases from Earth’s atmosphere and oceans will receive awards totaling $1,210,000 in the second year of the Scialog: Negative Emissions Science initiative, sponsored by Research Corporation for Science Advancement and the Alfred P. Sloan Foundation, with additional support from the Climate Pathfinders Foundation. The 22 individual awards of $55,000 will go to 20 researchers from a variety of institutions in the United States and Canada. Among the awardees is Adam Holewinski, Chemical & Biological Engineering, University of Colorado Boulder.
Climate change demands a paradigm change in the chemical industry and waste stream valorization.
Reverse osmosis modules comprised of composite polymer membranes represent a leading technology in desalination and purification of brackish water.
The covalent attachment of polymers has emerged as a powerful strategy for the preparation of multi-functional surfaces.
Current state-of-the-art composite materials are not light/strong enough for crewed missions to Mars and beyond.
