Five Berkeley Lab Researchers are 2013 APS Fellows

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

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

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.

Carolyn Bertozzi and George Smoot Elected to National Academy of Inventors

Carolyn Bertozzi and George Smoot are among 143 new Fellows of the fledgling National Academy of Inventors. The honor, for which they were nominated by their peers, is based on their history of outstanding inventions and discoveries.

Berkeley Lab Researchers Create a Nonlinear Light-generating Zero-Index MetaMaterial

Berkeley Lab researchers have used a unique optical metamaterial with zero-index refraction to generate phase mismatch–free nonlinear light, an important step towards efficient light generation for future quantum networks and light sources.

New Spectroscopic Technique Could Accelerate the Push for Better Batteries

A new technique developed at Berkeley Lab’s Advanced Light Source could help scientists better understand and improve the materials required for high-performance lithium-ion batteries that power EVs and other applications. The technique, which uses soft X-ray spectroscopy, measures something never seen before: the migration of ions and electrons in an integrated, operating battery electrode.

Remembrances of Things Past: Berkeley Lab Researchers Discover Nanoscale Shape-Memory Oxide

Berkeley Lab researchers have discovered a way to introduce a shape memory effect in bismuth ferrite that is larger than any observed in a metal. This discovery opens the door to applications in a wide range of fields, including medical, energy and electronics.

Overcoming Brittleness: New Insights into Bulk Metallic Glass

Berkeley Lab researchers have found a bulk metallic glass based on palladium that’s as strong as the best composite bulk metallic glasses and comparable to steel, aluminum and titanium.

Taking a New Look at Carbon Nanotubes

Two of the biggest challenges in carbon nanotube research have been met with the development by Berkeley Lab researchers of a technique that can be used to identify the structure of an individual carbon nanotube and characterize its electronic and optical properties in a functional device.

Of Fish Scales and Adaptable Armor – The Things That X-Rays Can Tell You

X-ray beams from Berkeley Lab’s Advanced Light Source uncovered the secret behind the scales of a fish tough enough to withstand piranha bites.
