ANIMATION Berkeley Lab co-led collaboration with DESY and TU Freiberg brings us a step closer to more efficient photovoltaics and solar fuel systems. In the past 50 years, scientists have made great advances in photovoltaic technologies that convert sunlight into electricity, and artificial photosynthesis devices that convert sunlight and water into carbon-free […]

STEM (scanning transmission electron microscopy) image of a one-dimensional array of F4TCNQ molecules (yellow-orange) on a gate-tunable graphene device. Credit: Berkeley Lab Removing one charged molecule from a one-dimensional array causes the others to alternately turn ‘on’ or ‘off,’ paving the way for information transfer in tiny circuits. Small electronic […]

Quartz vial (9 mm diameter) containing ~300 micrograms of solid 253Es. The illumination produced is a result of the intense radiation from 253Es. Credit: Haire, R.

An artistic rendering of the XMM-Newton (X-ray multi-mirror mission) space telescope. A study of archival data from the XMM-Newton and the Chandra X-ray space telescopes found evidence of high levels of X-ray emission from the nearby Magnificent Seven neutron stars, which may arise from the hypothetical particles known as axions.
