Electric current is deflected by a magnetic field - this leads to the so-called Hall effect. A surprising discovery has now been made at TU Wien: an exotic metal was examined and a giant Hall effect was found to be produced by the material, in the total absence of any magnetic field.

Lithium-sulfur batteries, given their light weight and theoretical high capacities, are a promising alternative to conventional lithium-ion batteries for large-scale energy storage systems, drones, electric vehicles, etc. But at present, they suffer from poor battery life, limiting their applicability. Now, scientists from Gwangju Institute of Science and Technology, Korea, have discovered a new catalyst materials ability to significantly improve lithium-sulfur battery life, opening doors to the...

 E-Mail A POSTECH-KAIST joint research team has successfully developed a technique to reach near-unity efficiency of SHEL by using an artificially-designed metasurface. Professor Junsuk Rho of POSTECHs departments of mechanical engineering and chemical engineering, and Ph.D. candidate Minkyung Kim and Dr. Dasol Lee of Department of Mechanical Engineering in collaboration with Professor Bumki Min and Hyukjoon Cho of the Department of Mechanical Engineering at KAIST have together proposed a tech...

High energy storage batteries for EVs need high capacity battery cathodes. New lithium-excess magnesium-rich cathodes are expected to replace existing nickel-rich cathodes but understanding how the magnesium and oxygen accommodate charge storage at high voltages is critical for their successful adaption. Research led by WMG, University of Warwick in collaboration with US researchers employed a range of X-ray studies to determine that the oxygen ions are facilitating the charge storage rather tha...

 E-Mail Some of the planets rarest metals - used in the manufacture of smartphones and other electrical equipment - are increasingly being found in everyday consumer plastics, according to new research. Scientists from the University of Plymouth and University of Illinois at Urbana-Champaign tested a range of new and used products including childrens toys, office equipment and cosmetic containers. Through a number of detailed assessments, they examined levels of rare earth elements (REEs) but ...

 E-Mail Scientists from the National Renewable Energy Laboratory (NREL) have developed a simple way to better evaluate the potential of novel materials to store or release heat on demand in your home, office, or other building in a way that more efficiently manages the buildings energy use. Their work, featured in Nature Energy, proposes a new design method that could make the process of heating and cooling buildings more manageable, less expensive, more efficient, and better prepared to flex...

Credit: Microwave Nano-Electronics Lab, UC Riverside. RIVERSIDE, Calif. -- Materials having excess electrons are typically conductors. However, moiré patterns -- interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern -- can suppress electrical conductivity, a study led by physicists at the University of California, Riverside, has found. In the lab, the researchers overlaid a single monolayer of tungsten disulfide (WS 2...
