New root canal sealer can more thoroughly fill gaps during root canal treatment compared to commercial sealants. Invention Summary: Root canal sealers are essential for filling gaps during treatment, but shrink upon setting, leaving undesirable gaps that promote infections. Rutgers University researchers have developed Elastomeric Polyurethane...

Low-Damage of Steel Members by Premising Buckling Deformation

Design specifications to prevent building collapse when exposed to a seismic event may be effective in preventing building failure; however, after such an event, the structure may be damaged, requiring repair or replacement. Use of various lateral force-resisting systems, moment-resisting frames, and concentrically braced frames (CBF) have been...

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...

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...
