Fast Volumetric Imaging of Fluorescent Tissue Structures and Activities
Researchers at the University of Arizona have developed a novel microscope imaging technique that generates high-resolution large-volume 3D images of tissue at subcellular resolution, and captures transient activities within the volume at 100 volume frames per second (vps). The invention breaks away from the traditional plane-scanning approach and implements...

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...

Functional Nanoglues for Stable Metal Single-Atom and Cluster Catalysts
Background Recent advances in catalysis by single-atom catalysts (SACs) and cluster catalysts have highlighted the unique catalytic properties of highly dispersed metal species. The use of single metal atoms or small clusters for catalysis is not only cost-effective but also significantly enhances the selectivity of a targeted reaction, resulting in...

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...
