Building a Two-Dimensional Magnet One Atom at a Time
Researchers synthesized a new two-dimensional ferromagnet and measured how its electronic and magnetic properties evolve with increasing thickness and temperature. Such atomically thin magnetic materials with tunable magnetic properties would be very useful in next-generation microelectronic and spintronic applications. Read more »
Optical Properties of Individual Tar Balls in the Free Troposphere
Tar balls are found in biomass-burning smoke, and their sunlight-absorption properties are highly uncertain. This study investigates the optical properties of individual tar balls in the free troposphere to better understand their influence on climate. Read more »
Why Do Batteries Sometimes Catch Fire and Explode?
In order to better understand how a resting battery might undergo thermal runaway after fast charging, scientists are using a technique called “operando x-ray microtomography” to measure changes in the state of charge at the particle level inside a lithium-ion battery after it’s been charged.

2023 Summer Shutdown Recap
The ALS is back in user operations after a 12-week summer shutdown. Most of the shutdown work centered around ALS-U tasks, including installing a full arc sector of the accumulator ring. Read more »
Vote for New UEC Members: Term Starting in 2024
The Advanced Light Source Users’ Executive Committee (UEC) invites you to participate in the election of three new UEC members to represent the ALS community. The new members will take office for a three-year term beginning January 1, 2024. View candidate statements and submit your votes by 11:59 p.m. Pacific Time on Wednesday, Nov. 22. Read more »
Immune Response Spurs Growth of “Soft” Kidney Stones
Matrix stones are an unusual type of soft kidney stone closely associated with the presence of bacteria from unchecked urinary tract infections. Researchers conducted a comprehensive study of surgically extracted matrix stones, work that highlights how host defense mechanisms against microbes can simultaneously encourage harmful stone formation.

Dahlia An, User Safety Specialist
Dahlia An is new to the ALS but not to Berkeley Lab. Read about how she works with users and beamline scientists and how it connects to her past lives as a researcher and undergraduate student instructor. And, learn how her hobbies still allow her to experiment. Read more »
Internal Currents in Lithium Batteries after Fast Charging
In lithium batteries after fast charging, researchers measured the persistence of internal currents and found that large local currents continue even after charging has stopped. The work uses hard x-ray 3D imaging in a novel way and sheds light on the causes of thermal runaway and the catastrophic failure of lithium batteries at rest. Read more »
Improving Carbon Retention in Grassland Soil from Point Reyes
Soil organic carbon directly influences the life-supporting services provided by soils, including the production of food and the regulation of atmospheric carbon dioxide. To better understand how minerals such as calcium affect carbon accumulation in soil, researchers studied soils collected from Point Reyes National Seashore. Read more »
