Warm Coat Drive at the ALS and Molecular Foundry
We are joining forces with the Molecular Foundry to collect clean, new or gently-worn coats for Alameda County Social Services. Now through December 19, you can donate your coats to boxes in the lobby of Building 6 or 67. Last year, we collected 93 coats! Contacts: Cindy Lee (ALS) and Suksham Barun (Molecular Foundry) Read more »
A High-Pressure Compound of Argon and Nickel: Noble Gas in the Earth’s Core?
Researchers demonstrated the synthesis of a thermodynamically stable compound of Ar and Ni at thermodynamic conditions representative of the Earth’s core. The results suggest that the abundance of Ar in the Earth’s core is beyond a simple solubility of Ar in molten Ni–Fe but in chemical reactions in nature. Read more »
The Beauty of Imperfections: Linking Atomic Defects to 2D Materials’ Electronic Properties
Two studies reveal surprising details on how some atomic defects emerge in transition metal dichalcogenides (TMDs), and how those defects shape the material’s electronic properties. The findings could provide a more platform for designing 2D materials for quantum information science and smaller, more powerful optoelectronics. Read more »
Machine Learning Helps Stabilize Synchrotron Light
Researchers showed that machine learning can predict noisy fluctuations in the size of beams generated by synchrotron light sources and correct them before they occur. The work solves a decades-old problem and will allow researchers to fully exploit the smaller beams made possible by recent advances in light source technology. Read more »
Scientists Explore Egyptian Mummy Bones With X-Rays and Infrared Light to Gain New Insight on Ancient Life
Researchers from Cairo University worked with teams at the ALS to study soil and bone samples dating back 4,000 years. The experiments are casting a new light on Egyptian soil and ancient mummified bone samples that could provide a richer understanding of daily life and environmental conditions thousands of years ago.

Machine Learning Enhances Light-Beam Performance at the Advanced Light Source
Researchers have successfully demonstrated how machine-learning tools can improve beam-size stability via adjustments that largely cancel out these fluctuations—reducing them from a level of a few percent down to 0.4 percent, with submicron precision. The demonstration shows that the technique could be viable for scientific light sources around the globe. Read more »
Go With the Flow: Scientists Design Better Batteries for a Renewable Energy Grid
Researchers developed a versatile yet affordable battery membrane—from a class of polymers known as AquaPIMs. This class of polymers makes long-lasting and low-cost grid batteries possible based solely on readily available materials such as zinc, iron, and water. Read more »
New MOF Can Take On Toxic Sulfur Dioxide Gas
An international team has developed a robust material that can selectively take in toxic sulfur dioxide gas at record concentrations and preserve it for use in chemical production. The researchers verified its performance using a combination of techniques that included x-ray experiments at the ALS. Read more »
Users’ Executive Committee Elections Begin November 4, 2019
Voting for new Users’ Executive Committee (UEC) members will begin on November 4, 2019 and continue through November 18, 2019. We are looking to elect five new members, including one ALS-based member. The newly elected members will take office for a three-year term beginning January 1, 2020. All active users are eligible to go to the UEC website, read about each of the candidates, and submit your votes. The election results will be posted on the site after the deadline. The outgoing committee members are Christine Beavers (Diamond, UK), Jennifer Ciezak-Jenkins (US Army Research Lab), Ethan Crumlin (Advanced Light Source, Berkeley Lab), Kelsey Stoerzinger (Pacific Northwest National Laboratory), and Francesca Toma (Chemical Sciences Division, Berkeley Lab).
