Low Cost Flame Retardant Polymers from Low Cost Olefinic Comonomers
This technology is an approach to using sulfenyl-halide polymerization with olefinic comonomers to prepare a new class of intrinsically flame-retardant polymers for the production of a wide range of thermoplastics, thermoplastic elastomers, and thermoset materials. Materials prepared with this technology have afforded a V0 UL-94V flame retardancy rating...

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...
