Fabrication of metal-insulator-semiconductor photoelectrodes

Background Photoelectrochemical (PEC) water splitting is a promising technology for converting solar energy into clean and storable chemical energy. In PEC cells, semiconductors play a key role in absorbing photons from the light source to create mobile charge carriers. Various semiconductor materials have been studied for the high-performance PEC cells,...

Amphiphilic macromolecules with novel hydrophobic segments

Invention Summary: Cardiovascular diseases are the leading cause of mortality in developed countries. Atherosclerosis, defined as the buildup of lipid rich plaques within the vascular intima, is the foremost pathology underlying these conditions. This causes irregular uptake of oxidized low-density lipoproteins (OxLDL) which leads...

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...
