Star, Branched, and Graft Polymers in Binders for Inkjet Additive Manufacturing for Personalized Dosage Tablets
THE CHALLENGE A major problem posed by the pharmaceutical industry is giving effective dosages while not giving excessive amounts of a particular drug. An estimated 80% of side effects in humans and animals are a direct result of inaccurate dosing because varying weights in patients. Additive manufacturing has emerged as a very promising method to...

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...

Wound Closure Devices 2019-816, 2020-867
BACKGROUNDWound closure devices for internal luminal repair have historically been limited to staples (nondegradable, commonly titanium), sutures, and/or adhesives. The urinary tract in particular is an area in which sutured repairs with bioabsorbable sutures remain the standard closure mechanism due to the risk of stones and UTIs with staples and the...

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...
