Tiny, individual crystals on the underside of a Mexican butterfly's wings give the insect a distinctive green color that allows it to hide from predators. Researchers now have shown for the first time how these crystals might grow.
Physicists have offered a way to mathematically describe a particular physics phenomenon called a phase transition in a system out of equilibrium. Such phenomena are central in physics, and understanding how they occur has been a long-held and vexing goal; their behavior and related effects are key to unlocking possibilities for new electronics and other next-generation technologies.
Lithium-oxygen fuel cells boast energy density levels comparable to fossil fuels and are thus seen as a promising candidate for future transportation-related energy needs. Several roadblocks stand in the way of realizing that vision. An engineering lab has focused on one of those roadblocks - the loss of battery power, also known as capacity fade.
Physicists have fabricated new two-dimensional quantum materials with breakthrough electrical and magnetic attributes that could make them building blocks of future quantum computers and other advanced electronics.
