This technology is a high-capacity water electrolyzer for hydrogen production based on ultrathin proton-conducting oxide membranes with higher electrolysis efficiency than conventional polymer electrolyte membrane (PEM) electrolyzers. This technology is a low-temperature water electrolyzer for hydrogen production that uses ultrathin oxide membranes to increase efficiency compared to conventional polymer electrolyte membrane (PEM) electrolyzers. Reduces membrane size by 2-4 orders of magnitude than conventional Nafion membranes.
This technology is a method for fabricating sulfonated polystyrene ion-exchange membranes (IEMs) designed to maintain high charge selectivity in high salinity environments. Controlled synthesis parameters are used optimize the performance of the ion-exchange membranes (IEMs). Such membranes are suitable for applications in electrodialysis desalination and other electromembrane processes.
The polymer composition also compromises the effectiveness of nanoparticles often added to these membranes to enhance their biological functions, causing these membranes to perform sub-optimally in certain biomedical applications. These nanospiky particles’ spikes can exert mechanical forces on bioparticles, enhancing the biological functionality of the membrane. This technology is a tunable nanoporous membrane assembled from layers of polymer films and nanospiky particles to filter, capture, and manipulate ultrasmall biological particles.
