Researchers mimicked these extreme impacts in the lab and discovered new details about how they transform minerals in Earth’s crust.

High-speed X-ray free-electron lasers have unlocked the crystal structures of small molecules relevant to chemistry and materials science, proving a

SLAC Edward Hohenstein, Emma McBride and Caterina Vernieri study what happens to molecules hit by light, recreate extreme states of matter like those inside stars and planets, and search for new physics phenomena at the most fundamental level. Edward Hohenstein, Emma McBride and Caterina Vernieri from the Department of Energy’s SLAC National Accelerator Laboratory will receive prestigious Early Career Research Program awards for studies of light-induced chemical reactions and how to control them, matter in extreme conditions and the physics of fundamental particles and forces. Three SLAC sc...

SLAC Exploring and manipulating the behavior of polar vortices in materials may lead to new technology for faster data transfer and storage. Our high-speed, high-bandwidth world constantly requires new ways to process and store information. Semiconductors and magnetic materials have made up the bulk of data storage devices for decades. In recent years, however, researchers and engineers have turned to ferroelectric materials, a type of crystal that can be manipulated with electricity. In 2016, the study of ferroelectrics got more interesting with the discovery of polar vortices – essential...

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, and the results have broad implications for developing future quantum and photonics technologies where light replaces electrons in computers and fluids in refrigerators, for example. In a QLED TV screen, dots absorb blue light and turn it into green or red. At the ...
