First Detailed Look at How Charge Transfer Distorts a Molecule’s Structure

When light hits certain molecules, it dislodges electrons and creates areas of positive and negative charge. An X-ray free-electron laser study has directly observed how this charge transfer affects a molecule's structure for the first time.

Scientists uncover surprising behavior of a fatty acid enzyme with potential biofuel applications

Although many organisms capture and respond to sunlight, enzymes – proteins that catalyze biochemical reactions – are rarely driven by light. A new study captures the full cycle of complex structural changes in an light-driven enzyme called FAP...

Scientists glimpse signs of a puzzling state of matter in a superconductor

High-temperature superconductors conduct electricity with no loss, but no one knows how they do it. SLAC scientists observed the signature of an exotic state of matter called “pair density waves” in a cuprate superconductor and confirmed that it...

Scientists uncover a process that stands in the way of making quantum dots brighter

Bright semiconductor nanocrystals known as quantum dots give QLED TV screens their vibrant colors. But attempts to increase the intensity of that light generate heat instead, reducing the dots’ light-producing efficiency. A new study explains why,...

First closeups of how a lithium-metal electrode ages

They discovered that the nature of the battery electrolyte, which carries charge between the electrodes, has a big impact on aging – a factor that needs to be taken into account when developing electrolytes that maximize a battery’s performance.
