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 »PPT-icon-35

HyMARC Aims to Hit Targets for Hydrogen Storage Using X-Ray Science

Understanding how materials absorb and release hydrogen is the focus of the Hydrogen Materials Advanced Research Consortium (HyMARC). At the ALS, the HyMARC Approved Program was recently renewed, underscoring the key role that soft x-ray techniques have played in addressing the challenges of hydrogen storage. Read more »

ALS at 30

October 5, 2023, marks 30 years since first light at the ALS. Over this time, the number of beamlines grew to more than 40, as many as 2,100 users have come to the facility each year, and over 16,000 publications have resulted from work here. Watch this space for special anniversary tidbits throughout the year. We’d also love to hear from you—please share your memories and see community submissions at this link! Read more »

Accelerating Sustainable Semiconductors With ‘Multielement Ink’

Scientists have developed “multielement ink”—the first “high-entropy” semiconductor that can be processed at low temperature or room temperature. The new semiconducting material could accelerate the sustainable production of next-gen microelectronics, photovoltaics, solid state lighting, and display devices. Read more »

Haris Mahic, Accelerator and Floor Operator

As an accelerator and floor operator, Haris’s work takes him all over the ALS. But, it is his photography hobby that has left an indelible mark on the ALS homepage. Let’s take a closer look at how he helps keep the ALS running and what brought him here in the first place. Read more »
