By designing a solid electrolyte that is rigid on one side and soft on the other, researchers have fabricated a lithium-metal battery that completely suppresses dendrite formation—a major safety hazard that can cause fires and shorten battery lifetime. This design also overcomes a tradeoff that is typically present in these batteries, by simultaneously eliminating dendrite […]

Hard-To-Stretch Silicon Becomes Superelastic
As a hard and brittle material, silicon has practically no natural elasticity. But in a new study, researchers have demonstrated that amorphous silicon can be grown into superelastic horseshoe-shaped nanowires that can undergo stretching of more than twice their original length, and still maintain their excellent electric properties. The results are exciting news for the […]
Light-Erasable Memory Promising For System-On-Panel Displays
Researchers have designed a memory device based on atomically thin semiconductors and demonstrated that, in addition to exhibiting a good performance in general, the memory can also be fully erased with light, without any electrical assistance. The new memory has potential applications for system-on-panel technology, in which all of the components of an electronic device […]
