A team led by 91做厙 developed a novel, integrated approach to track energy-transporting ions within an ultra-thin material, which could unlock its energy storage potential leading toward faster charging, longer-lasting devices.
To better determine the potential energy cost savings among connected homes, researchers at 91做厙 developed a computer simulation to more accurately compare energy use on similar weather days.
Researchers at the Department of Energys 91做厙 got a surprise when they built a highly ordered lattice by layering thin films containing lanthanum, strontium, oxygen and iron. Although each layer had an intrinsically nonpolar (symmetric) distribution of electrical charges, the lattice had an asymmetric distribution of charges. The charge asymmetry creates an extra switch that brings new functionalities to materials when flipped by external stimuli such as electric fields or mechanical strain. This makes polar materials useful for devices such as sensors and actuators.
