Experiments confirm that structural defects at the periphery are key in catalyst function. The SINS study is an important step in chronicling how the atomic structure of nanoparticles impacts their function as catalysts in chemical reactions. Read more »
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 »

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 »
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.

Meet the 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. Read more »
Glowing Crystals Can Detect, Cleanse Contaminated Drinking Water
Tiny, glowing crystals designed to detect and capture heavy-metal toxins such as lead and mercury could prove to be a powerful new tool in locating and cleaning up contaminated water sources. The crystals function like miniature, reusable sensors and traps, and are known as luminescent metal-organic frameworks, or LMOFs. Read more »
Scientists Trace ‘Poisoning’ in Chemical Reactions to the Atomic Scale
A team of researchers has employed a combination of measurements, including x-ray experiments at the ALS, to gather the most detailed information yet on problematic carbon-based deposits called “coke,” and to find ways to prevent its formation or reduce its effects. Read more »
Understanding Barriers to Higher-Capacity Rechargeable Batteries
Vanadyl phosphate can theoretically accept twice the number of lithium ions as battery materials currently in use. In practice, however, it doesn’t live up to expectations. New research at Beamline 6.3.1 using a variety of hard and soft x-ray spectroscopies helps zero in on why. Read more »
