Rational Optimization of Organic Solar-Cell Materials

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.

Respiratory Virus Study Points to Likely Vaccine Target

Respiratory syncytial virus (RSV) causes serious respiratory disease in infants and older adults, but no vaccine is yet available. 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.

U.S. Energy Secretary Rick Perry Visits the ALS

Secretary Perry visited the ALS and other locations at Berkeley Lab on March 27. Guided by ALS Interim Director Steve Kevan and Berkeley Lab Director Mike Witherell, he talked with users and staff about microtomography work on ceramic-matrix composites, battery research using STXM, and the Center for X-Ray Optics’ EUV lithography work. See photographs from the tour. Read more »

ALS Hosts “Five-Way” Meeting of DOE Light Sources

On April 23, the ALS hosted a meeting of the five DOE-funded light sources (ALS, SSRL, LCLS, APS, and NSLS-II). These “five-way” meetings, held biannually, bring together representatives from each facility to discuss common interests and issues. Topics of discussion included open data policies, business software, optics and detector development, workforce and career development, and diversity. Read more »

Share Your Photos to Celebrate the International Day of Light

Lightsources.org, an international collaboration of light sources, is participating in the International Day of Light (May 16) with a photo wall on its website. Users of any of the member facilities, including the ALS, are invited to share a picture of their work, research, or day-to-day life in science on the theme of “light in science.” Read more »

ALS Doctoral Fellowship Applications Due June 30

ALS Doctoral Fellowships in Residence allow early-career researchers to spend a year at the ALS working at the frontier of synchrotron radiation research and helping advance state-of-the-art techniques and applications. Applications will be accepted from June 1–June 30. Read more »

Users’ Executive Committee (UEC) Update

The UEC has elected Fanny Rodolakis (APS, Argonne National Laboratory) as vice chair. She will serve as UEC chair in 2019. Planning for the User Meeting, to be held October 2–4, is now in full swing, and the UEC is pleased to announce a new, full-day tutorial session on October 4 geared towards introducing new users and young scientists to a broad range of ALS techniques.

Monovalent Manganese for High-Performance Batteries

Scientists have detected a novel chemical state of the element manganese that was first proposed about 90 years ago. The discovery enables the design of a high-performance, low-cost battery that, according to its developers, outperforms Department of Energy goals on cost and cycle life for grid-scale energy storage.

Toward Control of Spin States for Molecular Electronics

Researchers demonstrated, via x-ray absorption spectroscopy, that a molecule’s spin state can be reversibly switched at constant room temperature by magnetism. The results represent a major step toward the goal of programmable, nanoscale molecular electronics for high-speed, low-power, logic and memory applications. Read more »PPT-icon-35 PDF-icon-35
