In a rechargeable battery, the electrolyte transports lithium ions from the negative to the positive electrode during discharging. The path of ionic flow reverses during recharging. The organic liquid electrolytes in commercial lithium-ion batteries are flammable and su...

Discarded tires can provide material useful for lower-cost sodium-ion batteries for energy storage.
Hard carbon materials recycled from tires continue to show great promise as anodes in sodium-ion batteries for large-scale energy storage, according to an Oak Ridge National Laboratory study led by Yunchao Li. The carbons, captured by pyrolyzing, or baking in the absence of oxygen, tir...

Radioactive materials have long been a part of American history—from the Manhattan Project to the development of nuclear power. The materials central to these innovations are actinides, or elements 89–103 on the periodic table that release large amounts of energy when atoms are spli...
Light drives the migration of charge carriers (electrons and holes) at the juncture between semiconductors with mismatched crystal lattices. These heterostructures hold promise for advancing optoelectronics and exploring new physics.

Epitaxy, or growing crystalline film layers that are templated by a crystalline substrate, is a mainstay of manufacturing transistors and semiconductors. If the material in one deposited layer is the same as the material in the next layer, it can be energetically fav...

Oak Ridge National Laboratory scientists combined imaging techniques to measure crystallization kinetics of perovskite films following exposure to a mixed halide vapor.

Researchers at the Department of Energy’s Oak Ridge National Laboratory have found a potential path to further improve solar cell efficiency by understanding the competition among halogen atoms during the synthesis of sunlight-absorbing crystals. 

In unbound calyx[4]pyrrole, two pyrrole “petals” are flipped up and two, down.

Atomic charges in chemical solutions are like Switzerland—they strive for neutrality. The tendency to balance charges drives dynamics when charged atoms or molecules, called ions, are present in solutions. Recently, researchers at the Department of Energy’s Oak Ridge National Laborat...

Lipid molecules have split personalities—one part loves water, whereas the other avoids it at all costs. Lipids make up cell membranes, the frontline defense in preventing cellular access to bacterial and viral invaders. Many researchers believe that the membrane is not just a scaf...
