Ultra-high-voltage Silcon Carbide Thyristor, submitted by Sandia researcher Stan Atcitty. This DOE Energy Storage Systems project, managed by Sandia in partnership with GeneSiC Semiconductor Inc., and the U.S. Army Armament Research, Development and Engineering Center (ARDEC), has developed an ultra-high-voltage silicon carbide thyristor. The semiconductor device allows next-generation "smart grid" power electronics system to be built up to 10 times smaller and lighter than current silicon-based technologies. These packaged-power devices are the world's first commercially available, high-voltage, high-frequency, high-current, high-temperature, single-chip SiC-based thyristors. Their performance advantages are expected to spur innovations in utility-scale power electronics hardware and to increase the accessibility and use of distributed energy resources.
Biomimetic Membranes for Water Purification, submitted by Sandia project lead Susan Rempe, jointly with Sandia Fellow and University of New Mexico professor Jeff Brinker and Jing-Bing Jiang of UNM's Earth and Planetary Sciences department. The new biomimetic membranes purify water through reverse osmosis (RO) technology. "We made a synthetic membrane that mimics the nanoscale design features of natural water purification channels," said Rempe. "By doing so, our initial membranes achieved a ten-fold improvement in water purification efficiency compared with state-of-the-art RO membranes." The selective, high-flux desalination membranes are formed of self-assembled nanopores tuned (with atomic-layer deposition) to mimic key structu
