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...

Photovoltaic Devices with Very High Breakdown Voltages

Background When a solar cell is operated in reverse bias in dark conditions, a very small drift current, called leakage current, flows due to minority carriers. Breakdown voltage for solar cell refers to the minimum applied reverse dark voltage that results in an exponential increase in leakage current. When solar cells are connected in series...

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...

Flexible Silicon Infrared Emitter

Effectively passivating a silicon cell leads to higher open circuit voltages and high efficiencies necessary for various electronic applications. Surface passivation is relevant for thinner wafers where recombination at the surface dominates total recombination. Thinner wafers are necessary as the voltage increases as a function of the excess carrier...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers

Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

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...
