Discovery of New Semiconductor Holds Promise for 2D Physics and Electronics

March 20, 2014

Researchers at Berkeley Lab’s Molecular Foundry have discovered a unique new two-dimensional semiconductor, rhenium disulfide, that behaves electronically as if it were a 2D monolayer even as a 3D bulk material. This not only opens the door to 2D electronic applications with a 3D material, it also makes it possible to study 2D physics with easy-to-make 3D crystals.

Bright Future for Protein Nanoprobes

March 17, 2014

Berkeley Lab researchers at the Molecular Foundry have discovered surprising new rules for creating ultra-bright light-emitting crystals that are less than 10 nanometers in diameter. These ultra-tiny but ultra-bright nanoprobes should be a big asset for biological imaging, especially deep-tissue optical imaging of neurons in the brain.

Five Berkeley Lab Researchers are 2013 APS Fellows

January 6, 2014

This year’s recently announced American Physical Society (APS) Fellows includes five scientists from Berkeley Lab, two from the Materials Sciences Division and one each from the Accelerator and Fusion Research, Nuclear Science, and Engineering divisions. APS Fellows are elected by their peers for “exceptional contributions to the physics enterprise; e.g., outstanding physics research, important applications of physics, leadership in or service to physics, or significant contributions to physics education.”

A Micro-Muscular Break Through

December 19, 2013

Berkeley Lab researchers have demonstrated a micro-sized robotic torsional muscle/motor made from vanadium dioxide that for its size is a thousand times more powerful than a human muscle, able to catapult objects 50 times heavier than itself over a distance five times its length faster than the blink of an eye.

Roots of the Lithium Battery Problem: Berkeley Lab Researchers Find Dendrites Start Below the Surface

December 17, 2013

Berkeley Lab researchers have discovered that the dendrite problem that can cause lithium-ion batteries to short-circuit, overheat and possibly catch fire originates below the surface of the lithium electrode and not at the surface as has been widely believed.
