PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids

The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

Enhanced Water Splitting with Protic Buffer/Electrolyte Cocatalysts

This invention is a protic co-catalyst used to increase the rate of electrolysis for splitting water to hydrogen and oxygen in a hydrogen evolving reaction. The co-catalyst is present in the electrolyte and is not consumed during the reaction. The co-catalyst may enhance the efficiency of water-splitting in systems that use a heterogenous catalyst,...
