It all starts with a 'spark': Berkeley lab delivers injector that will drive X-ray laser upgrade

DOE/Lawrence Berkeley National Laboratory

A team at Berkeley Lab has designed, built, and delivered a unique version of a device, called an injector gun, that can produce a steady stream of these electron bunches. The gun will be used to produce brilliant X-ray laser pulses at a rapid-fire rate of up to 1 million per second.

Scientists discover material ideal for smart photovoltaic windows

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Researchers at Berkeley Lab discovered that a form of perovskite, one of the hottest materials in solar research currently due to its high conversion efficiency, works surprisingly well as a stable and photoactive semiconductor material that can be reversibly switched between a transparent state and a non-transparent state, without degrading its electronic properties.

Superconducting X-ray laser takes shape in Silicon Valley

DOE/SLAC National Accelerator Laboratory
Business Announcement

An area known for high-tech gadgets and innovation will soon be home to an advanced superconducting X-ray laser that stretches 3 miles in length, built by a collaboration of national laboratories. On Jan. 19, the first section of the machine's new accelerator arrived by truck at SLAC National Accelerator Laboratory in Menlo Park after a cross-country journey that began in Batavia, Ill., at Fermi National Accelerator Laboratory.

DOE under secretary for science Paul Dabbar visits SLAC

DOE/SLAC National Accelerator Laboratory

Paul Dabbar, the Department of Energy Under Secretary for Science, visited SLAC National Accelerator Laboratory Jan. 17 for a day of tours and discussions on how the lab is driving scientific innovation. His visit included meetings with SLAC and Stanford leadership, as well as researchers and scientists involved in the lab's X-ray science, particle physics and astrophysics, technology innovation and applied energy programs.

Coupling experiments to theory to build a better battery

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

A Berkeley Lab-led team of researchers has reported that a new lithium-sulfur battery component allows a doubling in capacity compared to a conventional lithium-sulfur battery, even after more than 100 charge cycles.

X-rays reveal 'handedness' in swirling electric vortices

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Scientists used spiraling X-rays at Berkeley Lab to observe, for the first time, a property that gives left- or right-handedness to swirling electric patterns -- dubbed polar vortices -- in a layered material called a superlattice.

All in the family: Focused genomic comparisons

DOE/Joint Genome Institute
Peer-Reviewed Publication

Aspergillus fungi are pathogens, decomposers, and important sources of biotechnologically-important enzymes. In the Proceedings of the National Academy of Sciences, a team led by researchers at the Technical University of Denmark, the DOE Joint Genome Institute and the Joint BioEnergy Institute report the first outcome from the large-scale sequencing of 300+ Aspergillus species. These findings are a proof of concept of novel methods to functionally annotate genomes to more quickly identify genes of interest.

Ingredients for life revealed in meteorites that fell to Earth

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

A detailed study of blue salt crystals found in two meteorites that crashed to Earth -- which included X-ray experiments at Berkeley Lab found that they contain both liquid water and a mix of complex organic compounds including hydrocarbons and amino acids.
