  • Reversible Excited-State Photoacids and Photobases as Dynamic Fluorescence Sensors of Protonic Species
    Publication number: 20230358677
    Abstract: Systems and methods for sensing and measuring local pH, pOH, and other protonic species using reversible excited-state photoacids and photobases are described. Various reversible excited-state photoacids and/or photobases are described that through a dynamic sensing mechanism exhibit varied fluorescence or phosphorescence intensity based on local activity of protonic species. Photoacids and photobases can be used in combination with confocal fluorescent microscopy for quantifying local activity of protonic species.

  • Systems and methods for integrated solar photodialysis
    Patent number: 11673100
    Abstract: A photodialysis device that can desalinate saline streams is described herein. The device can have a desalination rate that is significantly faster than current solar thermal desalination technology. Salt is removed from water by passing ionic current derived from sunlight through this water using dye-sensitized membranes. The device can serve as a distributed, low-cost technology that can efficiently and effectively desalinate low salinity sources of water, which is particularly useful for agriculture and drinking water applications.

  • MEMBRANES FOR ENHANCING RATES OF WATER DISSOCIATION AND WATER FORMATION
    Publication number: 20210046423
    Abstract: Membranes for electrochemical technologies that operate at non-extreme acidic or basic conditions are described herein. The membrane can be a bipolar membrane having an anion-exchange layer, a cation-exchange layer, and a polymer layer containing a catalyst juxtaposed between the two layers. The catalyst can improve the rate for water dissociation and water formation at low applied bias thereby decreasing the overpotential and resistance for overall ion transport, especially when unequal pH values are used between the catholyte and anolyte.
