The first “unambiguous demonstration” of the coherent transport of phonons – atomic-scale sound waves – opens the door to improved thermoelectrics and possibly even phonon lasers.
E-Whiskers: Berkeley Researchers Develop Highly Sensitive Tactile Sensors for Robotics and Other Applications
Researchers with Berkeley Lab and UC Berkeley have created e-whiskers – highly sensitive tactile sensors made from carbon nanotubes and silver nanoparticles that should have a wide range of applications including advanced robotics, human-machine interfaces, and biological and environmental sensors.
President Obama named four Berkeley Lab-affiliated researchers as recipients of the Presidential Early Career Awards for Scientists and Engineers, the highest honor bestowed by the United States Government on science and engineering professionals in the early stages of their independent research careers.
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.”
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 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.
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.
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.
