Lithium Ion Batteries Might Get Cheaper and Better
December 22, 2020 | Leave a Comment
Oak Ridge National Laboratory (ORNL) researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today’s lithium-ion batteries that power electric vehicles and consumer electronics. The new family class named NFA, which stands for nickel-, iron- and aluminum-based cathode, is a derivative of lithium nickelate […]

Buoyancy Drives Hydrogen Convection For Mass Production
December 15, 2020 | Leave a Comment
A Helmholtz-Zentrum Berlin team has now presented a method to visualize convection in the electrolyte and to reliably simulate it in advance with a multiphysics model. Hydrogen produced by using solar energy could contribute to a climate neutral energy system of the future. But there are hurdles on the way from laboratory scale to large-scale […]

A New State of Matter For High Temperature Superconductors
December 10, 2020 | Leave a Comment
University of Hamburg scientists have pointed out how to create a time crystal in an intriguing class of materials, the high-temperature superconductors. They propose to drive these superconducting materials into a time crystalline state by inducing Higgs excitations via light. When you cool down liquid water, it crystallizes into ice. Consider a bucket filled with […]
