Super low altitude satellite to operate at 180 kilometers which is over two times closer than the Space Station

Japan Tsubame, Super Low Altitude Test Satellite, is a JAXA satellite intended to demonstrate operations in very low Earth orbit (below 200 km), using ion engines to cancel out aerodynamic drag and equipped with sensors to determine atomic oxygen density, an exposure facility to measure material degradation in the 200 km orbit, and a small …

Los Alamos quantum dots will make cost effective double-pane solar windows

Using two types of “designer” quantum dots, researchers are creating double-pane solar windows that generate electricity with greater efficiency and create shading and insulation for good measure. It’s all made possible by a new window architecture which utilizes two different layers of low-cost quantum dots tuned to absorb different parts of the solar spectrum. Above …

Yttrium hydrogen compound should be room temperature superconductor when under extreme pressure

The hunt for high temperature superconductivity has been reinvigorated by the experimental discovery that compressed H2S exhibits a Tc of up to 203K at megabar pressures (1Mbar=100GPa). A collaboration between the University of Cambridge and Jilin University has published the results of a computational search for materials that might superconduct at even higher temperatures. An …

US Army improving the regrowth of bone, muscle and skin

US Army researchers are using fillers to bridge the gap in damaged bones, hoping to figuratively bridge the gap between current regenerative techniques and the ideal: people regrowing lost limbs. Stephanie Shiels with the U.S. Army Institute of Surgical Research, Fort Sam Houston, Texas, talked about her research to develop a synthetic bone gap filler …

Lithium niobate could enable a photonics revolution the way silicon enabled computer revolution

The birthplace of the photonics revolution may well be named after lithium niobate. While, Lithium Niobate Valley doesn’t have the same ring as Silicon Valley, this material could be for optics what silicon was for electronics. Lithium niobate is already one of the most widely used optical materials, well-known for its electro-optic properties, meaning it …

Single thin lens able to focus the entire visible spectrum will transform augmented and virtual reality

The Harvard School of Engineering and Applied Sciences (SEAS) has developed the first single lens that can focus the entire visible spectrum of light — including white light — in the same spot and in high resolution. This has only ever been achieved in conventional lenses by stacking multiple lenses. * Metalenses are thin, easy …
