High school and undergraduate students don’t usually get a lot of real-world programming and hardware development experience, especially not with things like neural networks and synchrotron light source beamline components. Eighteen students got thrown into the deep end with these topics during their internships at the ALS. Read more »

Facility News and Shutdown Recap: Summer 2019
It’s been a busy summer at the ALS, with developments ranging from the delivery of a new prototype magnet for testing, to the refurbishing of the Building 80 cubicle farm and lounge area. A five-week shutdown checked off several important upgrades and installations, while other Building 6–related projects proceeded in parallel. Read more »
Infrared Nano-Mapping of Local Strain in 2D Materials
Researchers have demonstrated an infrared technique to map and analyze strain in atomically thin crystals of hexagonal boron nitride (hBN) at the nanoscale. This ultrasensitive strain-imaging method could be a promising tool for the examination of low-dimensional materials of interest for electronic and photonic devices. Read more »
Fundamental Property of Arginine Revealed Through Solvation
Just 20 amino acids act as building blocks for all our proteins, but their chemical properties have been difficult to study at the most fundamental level. Combining experiments and theory at the ALS, researchers have now determined the ionization energy of arginine, an amino acid with over 100 isomers. Read more »
Newly Discovered Minerals Reveal Anomalous Origins
Researchers characterized two highly unusual nickel-containing minerals, both unearthed in an ancient geological site in southern central Siberia. The findings extend our understanding of naturally occurring mineral species and varieties and provide useful insights into the environments leading to the formation of potentially valuable mineral ores.

Renewed Prospects for Rechargeable Mg Batteries
Contrary to previous reports, it’s possible to create a rechargeable battery using magnesium ions if the electrode material is first conditioned at high temperature. With twice the charge of lithium ions, magnesium ions hold great promise as the basis for high-energy-density batteries suitable for use in electric vehicles. Read more »
In Memoriam: Charles Fadley, Pioneer in X-Ray Photoelectron Spectroscopy
Charles “Chuck” Fadley, a pioneer in x-ray photoelectron spectroscopy, died at his home in Berkeley on August 1 after several years of treatment for cancer. He held the positions of distinguished professor emeritus of physics at UC Davis, and Advanced Light Source professor and senior faculty scientist at Berkeley Lab. He was 77. Read more »
Sulfur-linked cyanobiphenyl-based liquid crystal dimers and the twist-bend nematic phase
The synthesis and characterization of cyanobiphenyl-based liquid crystal dimers containing sulfur links between the spacer and mesogenic units are described. Resonant x-ray scattering studies of the twist-bend nematic phase at both the carbon and sulfur absorption edges were performed to determine the critical behaviour of the helical pitch at the transition to the nematic phase.

New Quick Start Guide for Users
The ALS Quick Start Guide provides contact information, maps, and other useful tips to ensure your time at the ALS goes smoothly. Check out the electronic version online or pick up a paper copy from the User Office. Read more »
Advanced Light Source Five-Year Strategic Plan
The updated ALS Strategic Plan for the next five years is now available online. It provides an introduction to the ALS, explains strategic priorities for science thrusts and instrumentation, and covers the ALS Upgrade. The document also discusses the user program, workforce development, safety, accelerator projects, and initiatives. Read more »
