Low-Temperature Welding of Copper Nanoporous Powders for High Surface Area Electrodes
Background Nanoporous metals, especially copper, are critical in fields like hydrogen production, battery technology, and energy storage due to their high surface area and conductivity. However, traditional sintering methods require high temperatures, which often reduce porosity and compromise performance. Additionally, the mechanical instability of...

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...

Polymeric Mac-Imprint Stamp Materials for High-Density Defect-Free Patterning of Semiconductors
Metal-assisted chemical imprinting (Mac-Imprint) is a contact-based wet etching process that combines metal-assisted chemical etching (MACE) and nanoimprint lithography (NIL). Mac-Imprint processes have been used for semiconductor patterning with arbitrary and complex 3D micro- and nano-structures. While porous catalytic metal thin-films can be used...

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...
