Researchers designed and fabricated a nanomagnet array in which competing (“frustrated”) magnetic interactions can be directly tuned. Frustrated interactions are key to a wide range of phenomena, from protein folding and magnetic memory to fundamental studies of emergent exotic states. ... Read more »

On January 22, the third in a series of online ALS user forums was held on the Advanced Light Source Upgrade (ALS-U) project. Presentations included an overview of the project, an update on the ALS-U beamline selection process, and ideas for the future of soft matter research at the ALS. The next forum will be held Thursday, March 1, at 10 a.m. PT. ... Read more »
The User Office is accepting new General User Proposals (GUPs) from scientists who wish to conduct research at the ALS in the 2018-2 (August–December) cycle. The deadline for submissions is March 7, 2018. Applicants are reminded that they may request joint access to the Molecular Foundry, a nanoscience user facility at Berkeley Lab, to support their ALS activities. ... Read more »
I am delighted to serve as interim ALS division director in the wake of Roger Falcone’s departure. I want first to thank Roger for his wonderful leadership. Over my 35 years of service, it has been exhilarating to see the ALS develop into a powerhouse facility that has attracted an exceptional staff and user community, and I look forward to working with staff and users on all ALS and ALS-U activities. ...

This year’s ALS User Meeting, which celebrates 25 years of light at the ALS, will feature special keynotes focused on the ALS’s past, present, and future. UEC members Jennifer Ciezak-Jenkins, Alex Frañó, and Michael Jacobs are also revamping the format to include a new “tutorial day” featuring introductory and advanced sessions. Stay tuned for more details! ... Read more »
Using the new MAESTRO platform at the ALS, scientists found that the exotic behavior of electrons in the 2D semiconductor, WS2, may be highly tunable, with possible applications for electronics and other forms of information storage, processing, and transfer. ... Read more »
An antibody was modified to activate a specific pathway of the immune system, demonstrating its value in killing tumor cells. The work provides a platform for disentangling different immune-system pathways and could lead to the design of improved immunotherapies.

Postdoc researcher Sergey Nikitin has been at the ALS since February 2017, working in the X-Ray Optics Laboratory (XROL), where he’s researching and developing new optical metrology tools and methods. ... Read more »
The mechanisms limiting the performance of hematite electrodes—potentially key components in producing fuel from the sun—have been clarified in interface-specific studies under realistic operating conditions, bringing us a step closer to storing solar energy in chemical fuels.

If you add more lithium to the positive electrode of a lithium-ion battery, it can store much more charge in the same amount of space, theoretically powering an electric car 30 to 50 percent farther between charges. But these lithium-rich cathodes quickly lose voltage, and years of research have not been able to pin down why—until now.
