A team of Brown University researchers has found a way to double the toughness of a ceramic material used to make solid-state lithium ion batteries. The strategy, described in the journal Matter, could be useful in bringing solid-state batteries to the mass market. "There's huge interest in replacing the liquid electrolytes in current batteries with ceramic materials because … [Read more...] about Researchers make next-generation, high-toughness battery component

Electrification of the transportation sector -- one of the largest consumers of energy in the world -- is critical to future energy and environmental resilience. Electrification of this sector will require high-power fuel cells (either stand alone or in conjunction with batteries) to facilitate the transition to electric vehicles, from cars and trucks to boats and … [Read more...] about Engineers develop new fuel cells with twice the operating voltage as hydrogen

A research group from the RIKEN Center for Emergent Matter Science have managed to manipulate and track the movement of individual magnetic vortices called skyrmions, which have been touted as strong candidates to act as information carriers in next-generation storage devices and as synapses for neuromorphic computing, They were able to move and measure skyrmions of 80 … [Read more...] about Manipulating tiny skyrmions with small electric currents

All efforts to replicate in tokamak fusion facilities the fusion energy that powers the sun and stars must cope with a constant problem -- transient heat bursts that can halt fusion reactions and damage the doughnut-shaped tokamaks. These bursts, called edge localized modes (ELMs), occur at the edge of hot, charged plasma gas when it kicks into high gear to fuel fusion … [Read more...] about A proven method for stabilizing efforts to bring fusion power to Earth

Scientists at Laboratory of Organic Electronics, Linköping University, have developed an organic electrochemical transistor that they can use to measure and study in fine detail a phenomenon known as extracellular electron transfer in which bacteria release electrons. The study of bacteria and their significance for the natural world, and for human society and health, is a … [Read more...] about Using tiny electrodes to measure electrical activity in bacteria
