Berkeley Lab
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-ray and infrared light, for scientific research and technology development in a wide range of disciplines.

A New Way to Determine the 3D Structure of Molecules

Researchers have created a sort of nanoscale display case that enables new atomic-scale views of hard-to-study chemical and biological samples. The work could help to reveal new structural details for a range of challenging molecules by stabilizing them inside sturdy structures known as metal-organic frameworks (MOFs). ... Read more »


New UEC Members

The results of the ALS Users’ Executive Committee (UEC) election are in, and six new members have been chosen, including a new student representative. They will each serve on the committee for three years (two years for the student representative), starting on January 1, 2017.

Exploring the Structure of Aqueous Solutions with SALSA

Researchers have published a series of papers that open up the possibility of probing hydrogen bonds in aqueous solutions by combining x-ray emission spectroscopy and resonant inelastic soft x-ray scattering, using the specialized Solid and Liquid Spectroscopic Analysis (SALSA) endstation at Beamline 8.0.1. ...

X-Rays Help Evaluate Quality of 3D-Printed Repairs

Laser 3D printing is a promising way to repair machine parts (such as jet-engine turbine blades) made of single-crystal superalloys. But microstructural inhomogeneities created by the high-power laser are a major reliability concern, so researchers employed x-ray Laue microdiffraction to probe the microstructure. ... Read more »

Fernando Sannibale, Division Deputy for Accelerator Operations and Development 

Fernando Sannibale, previously the principal investigator of the Advanced Photoinjector Experiment (APEX) at LBNL, has recently taken on a new role as leader of the ongoing ALS Accelerator Physics program in the Accelerator Technology and Applied Physics Division and will also serve as the ALS Division Deputy for Accelerator Operations and Development. We recently sat down with Sannibale to talk about his years at the ALS and what he hopes to accomplish in his new role. ... Read more »

3D Visualization of the Behavior of Grease Additives

Lubricants help keep civilization running smoothly, but is there room for improvement? With the goal of increasing the life span and lowering the costs of all kinds of mechanical and biological systems, researchers used x-ray microtomography to visualize the behavior of grease additives under working conditions. ...
