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...

Internal Vibration Isolation for A Cryogen-free Cryostat to Operate Scanning Tunneling Microscopes
Invention Summary: Cryogen-free cryostats have attracted attention due to their significant reduction in cost and labor to cool systems to cryogenic temperatures. With cryogen-free cryostats helium does not need to be refilled, which allows experiments to run indefinitely without interruption. This also means that the costly drawing from the worlds...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
