Berkeley Lab
Bringing Science Solutions to the World

ALS

The Advanced Light Source is a Department of Energy-funded synchrotron facility that provides users from around the world access to the brightest beams of soft x-rays, together with hard x-rays and infrared, for scientific research and technology development in a wide range of disciplines.

Announcement

COVID-19 Status Update

Berkeley Lab is gradually bringing staff back onto the Lab’s sites over the coming months, consistent with federal, state, and local guidance. These plans began on Monday, June 1, with a small on-site pilot group.

A number of the ALS-ENABLE crystallography beamlines, soft x-ray tomography (2.1), and the BioSAXS beamline (12.3.1), are available for remote collection and service operations in support of COVID-19 research. Please apply through the RAPIDD proposal process.

Department of Energy Basic Energy Sciences light sources want to ensure they are doing everything possible to enable research into the SARS-CoV-2 virus and the search for an effective vaccine or other treatment. The DOE supports research into structural biology in collaboration with the National Institutes of Health and other partners. This portal collects relevant structural biology resources in a single location, listing their basic characteristics and a point of contact for each. Read more

Unexpected Rise in Ferro-electricity as Material Thins

Researchers showed that hafnium oxide surprisingly exhibits enhanced ferroelectricity (reversible electric polarization) as it gets thinner. The work shifts the focus of ferroelectric studies from more complex, problematic compounds to a simpler class of materials and opens the door to novel ultrasmall, energy-efficient electronics.

Study Gains New Insight Into Bacterial DNA Packing

When bacteria are put in different environments, their genes start to adapt remarkably quickly because the proteins making up their chromosomes can pack and unpack rapidly. Researchers have now imaged this process at the molecular level, a discovery that could eventually enable scientists to develop strategies to control microbial behavior. Read more »

Will Hutcheson, Mechanical Engineering Group Leader

Will Hutcheson has been problem solving since childhood—a necessity growing up on a farm. Playing college football cemented his appreciation for cohesive teams, a mindset that has served him well at Berkeley Lab, the home of team science. Learn more about his vision for the ALS. Read more »

Long Chains Stabilize Higher-Efficiency Solar Cells

Perovskite thin films have many attractive properties for use in photovoltaics, but their assembly into practical devices has led to trade-offs between efficiency and stability. The addition of surfactant-type molecules with hydrophobic chains helped produce perovskite solar cells that are both efficient and stable. Read more »
