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...

Intelligent Textiles Prepared from Nanofiber Yarns and Polymer Fiber Actuators

While there has always been a desire for smart textiles, including fabrics which adapt depending on environmental stimuli, it has yet to be effectively accomplished due to the lack of suitable materials. These polymer fiber actuators have enabled the creation of fabrics that can reversibly change properties such as porosity, shape, color and texture....

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...

Biscrolling Nanopowders and Carbon Nanotube Sheets into Fibers, Yarns and Textiles

Non-Confidential Description:The technology is the first known method to spin biscrolled fibers/yarns from nanopowder materials using carbon nanotube (CNT) sheets as the host. Nanopowder materials (nanoparticles, nanofibers) are loaded onto the CNT sheets to form bi-layered sheets, which are then scrolled into fibers. A key advantage of this technology...
