About the Seminar: Higher levels of phosphates in surface water are a significant concern as they cause the eutrophication of freshwater systems. Traditional phosphate monitoring methods require complicated, heavy instrumentation and labor-intensive methods and are usually expensive. An alternative is paper-based microfluidics (µPADs) because they are inexpensive (<$1), fast (<10min assay time), user-friendly, and biodegradable. Current approaches using µPADs […]

About the Seminar: Widespread adoption of renewable energy is limited by the lack of low-cost long-duration energy storage. Redox flow batteries (RFBs) are an attractive option to meet this energy storage need because their power and energy components can be scaled independently by storing energy with redox-active materials dissolved in solution. To date, RFB electrolytes […]

Aerosol-OT (AOT) reverse micelles are a well-known, self-assembled model system for studying water in nanoconfinement. Although all-atom molecular dynamics (MD) simulations universally find AOT reverse micelles to be non-spherical, most theories about the reverse micelles still assume a spherical shape for simplicity, such as the core/shell hypothesis. This simplification ignores any interactions between the shape […]
