Me too, surprised it doesn't get more coverage.
Submission + - Step toward liberating electronic devices from their power cords (vanderbilt.edu)
Science_afficionado writes: A new type of supercapacitor that can hold a charge when it takes a lickin’ has been developed by engineers at Vanderbilt University. It is the first “multi-functional” energy storage device that can operate while subject to realistic static and dynamic loads – advancing the day when everything from cell phones to electric vehicles will no longer need separate batteries. These devices could make it possible to design electrical devices that are not limited by plugs and external power sources.
Submission + - Grad student makes nanowires just three atoms thick (vanderbilt.edu)
Science_afficionado writes: A Vanderbilt University graduate student, working at Oak Ridge National Laboratory, has discovered a way to create nanowires capable of linking transistors and other components made out of the monolayer material TMDC. His accomplishment is an important step toward creating monolayer microelectronic devices, which could be as thin and flexible as paper and extremely tough.
Submission + - Progress reported in creating "homo minutus" -- a benchtop human to test drugs (vanderbilt.edu)
Science_afficionado writes: Vanderbilt University scientists reported significant progress toward creating "homo minutus" — a benchtop human — at the Society of Toxicology meeting on Mar. 26 in Phoenix. The advance is the successful development and analysis of a human liver construct//organ-on-a-chip that responds to exposure to a toxic chemical much like a real liver. The achievement is the first result from a five-year, $19 million multi-institutional effort led by Los Alamos National Laboratory (LANL), to develop four interconnected human organ constructs — liver, heart, lung and kidney — that are based on a highly miniaturized platform nicknamed ATHENA (Advanced Tissue-engineered Human Ectypal Network Analyzer). The project is supported by the Defense Threat Reduction Agency. Similar programs to create smaller-scale organs-on-chips are underway at the Defense Advanced Research Projects Agency and the National Institutes of Health.
Submission + - Nanoscale terahertz optical switch breaks miniaturization barrier (vanderbilt.edu) 1
Science_afficionado writes: There is a general consensus that ultimately photons will replace electrons running through wires in most of our microelectronic devices. One of the current technical barriers to the spread of optoelectronics has been the difficulty in miniaturizing the ultrafast optical switches required. Now a team of physicists at Vanderbilt has made terahertz optical switches out of nanoparticles of vanadium dioxide, a material long known for its ability to rapidly change phase between metallic to semiconducting states. They report in the Mar. 12 issue of Nano Letters that they have created individually addressable switches that are 200 nm in diameter and can switch between transparent and opaque states at terahertz rates.
