Berkeley Lab User Facilities Prominent in SSURF Annual Meeting

Representatives from the Lab’s five national user facilities attended the Society for Science at User Research Facilities (SSURF) Annual Meeting in late June. JGI Director Nigel Mouncey presented, “How Facilities Can Partner With Industry to Strengthen the Scientific Infrastructure.” The Molecular Foundry’s Alison Hatt, who also serves on the SSURF Board of Directors, moderated a session.

3D Localization of Nanoscale Battery Reactions

What stands in the way of batteries that last a week or charge in five minutes? Part of the answer lies in the chemical and structural changes that happen deep inside a battery during use. At the Advanced Light Source, a new tool combines ptychography, tomography, and spectroscopy, enabling scientists to pinpoint the locations of chemical reactions inside batteries in three dimensions at the nanoscale.

From Moon Rocks to Space Dust: Berkeley Lab’s Extraterrestrial Research

From moon rocks to meteorites, and from space dust to a dinosaur-destroying impact, the Department of Energy’s Berkeley Lab has a well-storied expertise in exploring samples of extraterrestrial origin. More>

Meet Leda: Mother of Light Is Also New ALS Insertion Device

In Greek mythology, Leda is a Spartan queen and mother of the twins Castor and Pollux. In reference to the myth, Leda is also the name of the ALS’s recently delivered insertion device — an in-vacuum undulator. For the next eight months, Leda is taking up residence in the Building 15 high bay, awaiting installation during the January 2019 shutdown. More>

Tracing Interstellar Dust Back to Solar System’s Formation

Experiments conducted at Berkeley Lab helped to confirm that samples of interplanetary particles – collected from Earth’s upper atmosphere and believed to originate from comets – contain dust leftover from the initial formation of the solar system. Scientists from the University of Hawaii at Manoa used the Advanced Light Source and the Molecular Foundry for their research. More>

Rational Optimization of Organic Solar-Cell Materials

With help from the Advanced Light Source, researchers have established a new quantitative model that connects molecular interactions in organic solar-cell materials to device performance. The work suggests a way to quickly identify ideal material mixtures and processing methods, bypassing trial-and-error strategies and minimizing labor-intensive synthesis. More>

Non-Crystal Clarity: Scientists Find Ordered Magnetic Patterns in Disordered Magnetic Material

A team of scientists working at Berkeley Lab has confirmed a special property known as “chirality” — which potentially could be exploited to transmit and store data in a new way — in nanometers-thick samples of multilayer materials that have a disordered structure. More>

Respiratory Virus Study Points to Vaccine Target

Respiratory syncytial virus (RSV) causes serious respiratory disease in infants and older adults, but no vaccine is yet available. At the Advanced Light Source, researchers have now determined the molecular structures of human antibodies bound to an RSV surface protein, providing a promising route for designing a vaccine effective against a broad range of RSV strains.

Steve Kevan Named Director of Berkeley Lab’s Advanced Light Source

After an international search, Stephen “Steve” Kevan has been named the new director of the Advanced Light Source. Kevan, a condensed matter physicist, had served as ALS director in an interim capacity since January, when the preceding director, Roger Falcone, stepped down after more than 11 years in the role. Previously, Kevan was the ALS division deputy for science for more than five years. More>

Berkeley Lab Paves the Way for Real-Time Ptychographic Data Streaming

Real-time streaming of data produced by ptychographic imaging — which combines scanning microscopy with diffraction measurements to characterize the structure and properties of matter and materials — is changing the way scientists run experiments at the Advanced Light Source and, eventually, other light sources across the DOE complex.
