Postdocs Sinead Griffin (Materials Sciences) and Ruimin Qiao (Advanced Light Source) represented the Lab at Uncharted: The Berkeley Festival of Ideas. Griffen discussed exploring science from high-energy physics to condensed matter, while Qiao talked about researching materials for energy applications. The event features on-stage conversations, music, dance, and workshops.
President Obama hosted the White House Frontiers Conference on Oct. 13, which brought together top innovators to discuss advances in science and technology. Lab researchers Etosha Cave and Peidong Yang participated in the panel on Global Frontiers to discuss climate change and the clean energy revolution.
A team led by Ali Javey of the Materials Sciences Division has created a transistor with a working 1-nanometer gate. For comparison, a strand of human hair is about 50,000 nanometers thick. The key was to use carbon nanotubes and molybdenum disulfide (MoS2), an engine lubricant commonly sold in auto parts shops. More>
Researchers have observed, for the first time, an exotic 3-D racetrack for electrons in ultrathin slices of a tiny crystal they made at Berkeley Lab. The team witnessed a unique behavior in which electrons rotate around one surface, then through the bulk of the material to its opposite surface and back. More>
Scientists at Berkeley Lab and Cornell University have successfully paired ferroelectric and ferrimagnetic materials so that their alignment can be controlled with a small electric field at near room temperatures. The achievement could open doors to ultra low-power microprocessors, storage devices and next-generation electronics. More>
Light-emitting, four-armed nanocrystals could someday form the basis of an early warning system in structural materials by revealing microscopic cracks that portend failure. The approach could be a big step towards self-healing materials, and the tetrapods could potentially be used to detect the presence of cancer cells in tissue samples. More>
“Makers” is a word that evokes tinkerers and hobbyists, yet many scientists have begun to embrace the build-it-yourself ethos to advance their research in a variety of fields, including energy, transportation, neuroscience and consumer electronics. Scientists at national labs — such as Berkeley Lab’s Ron Zuckermann (left) — are also getting creative with maker technologies. More>
Materials scientist Gerbrand Ceder has been awarded the Materials Theory Award from the Materials Research Society. Ceder was recognized for developments in creating the field of computationally guided materials design, including the prediction of functional, thermodynamic and kinetic properties, their integration with experiments, and the field of high-throughput computation.
Researchers have created a sort of nanoscale display case that enables new atomic-scale views of hard-to-study chemical and biological samples. Their work could help to reveal new structural details for a range of challenging molecules, such as complex chemical compounds and potentially new drugs, by stabilizing them inside metal-organic frameworks (MOFs).
