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.

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.

Berkeley Lab Study Finds Moving Select Computer Services to the Cloud Promises Significant Energy Savings

June 11, 2013

A six-month study led by Berkeley Laboratory, with funding from Google, has found that moving common software applications used by 86 million U.S. workers to the cloud could save enough electricity annually to power Los Angeles for a year.

Meeting the Computing Challenges of Next-Generation Climate Models

March 26, 2013

Berkeley Lab recently hosted an international workshop that brought together top climatologists, computer scientists and engineers from Japan and the United States to exchange ideas for the next generation of climate models as well as the hyper-performance computing environments that will be needed to process the data from those models. It was the 15th in a series of such workshops that have been taking place around the world since 1999.

Computer Simulations Yield Clues to How Cells Interact With Surroundings

March 21, 2013

Berkeley Lab scientists have developed a computer model of a protein that helps cells interact with their surroundings. Like its biological counterpart, the virtual integrin snippet is about twenty nanometers long. It also responds to changes in energy and other stimuli just as integrins do in real life. The result is a new way to explore how the protein connects a cell’s inner and outer environments.

ESnet’s New Map Gives Up-to-the-Minute Network Data

January 17, 2013

A new interactive map developed by the Department of Energy’s ESnet (Energy Sciences Network) provides a detailed, up-to-the-minute look at the level of traffic traversing the various sections of the network as it connects 40 research sites around the country.
ESnet is currently the world’s fastest coast-to-coast science network with a national backbone with 100 gigabit-per-second [...]

How Computers Push on the Molecules They Simulate

January 3, 2013

Computer simulations are essential to test theories and explore what’s inaccessible to direct experiment. Digital computers can’t use exact, continuous equations of motion and have to slice time into chunks, so persistent errors are introduced in the form of “shadow work” that distorts the result. Berkeley Lab and UC Berkeley scientists have learned to separate the physically realistic aspects of the simulation from the artifacts of the computer method.
