Engineered Sorbents and Process for Selective Removal of Perfluorinated Organics Species from Water
This technology represents a new chemical process for selective removal of greater than 90% of the PFAS from contaminated water per pass through a sorption stage. The separation media comprises a selective surface modifier, with tunable properties, incorporated on an inexpensive material, which may be a cellulose sponge, fiber, or powder.
Background:
Perfluorinated...

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...
