ALS Work Using Scattering/Diffraction
These techniques make use of the patterns of light produced when x-rays are deflected by the closely spaced lattice of atoms in solids and are commonly used to determine the structures of crystals and large molecules such as proteins.
Full Energy Range Resonant Inelastic X-ray Scattering of O2 and CO2: Direct Comparison with Oxygen Redox State in Batteries
The evolving oxygen state plays key roles in the performance and stability of high-energy batteries involving oxygen redox reactions. Comparison of the mRIXS profiles of four different oxygen states reveals that oxygen redox states in batteries have distinct widths and positions along the excitation energy. Read more »
Survival of T. rex Microvascular Structures from Deep Time
Researchers used several analytical techniques at the ALS to demonstrate how soft-tissue structures may be preserved in dinosaur bones, countering long-standing scientific dogma that protein-based body parts cannot survive more than one million years. Read more »
How a New Electrocatalyst Enables Ultrafast Reactions
With key data from the ALS, researchers discovered how a new, low-cost electrocatalyst enables an important oxygen reaction to proceed at an ultrafast rate. The work provides rational guidance for the development of better electrocatalysts for applications such as hydrogen-fuel production and long-range batteries for electric vehicles. Read more »
Blending Ionic and Coordinate Bonds in Hybrid Semiconductor Materials: A General Approach toward Robust and Solution-Processable Covalent/Coordinate Network Structures
Blending ionic and coordinate bonds in copper iodide based hybrid semiconductor materials with extended covalent/coordinate network structures leads to greatly enhanced solubility and solution processability, making it possible to form high-quality films for device fabrication. Read more »
X-ray Crystal Structures of the Influenza M2 Proton Channel Drug-Resistant V27A Mutant Bound to a Spiro-Adamantyl Amine Inhibitor Reveal the Mechanism of Adamantane Resistance
The M2 proton channel, shown with front and back monomer helices removed, is an anti-influenza drug target. Here, a bound inhibitor blocks the transport of protons through the V27A mutant channel. Read more »
Highly Permeable Perfluorinated Sulfonic Acid Ionomers for Improved Electrochemical Devices: Insights into Structure-Property Relationships
Perfluorinated sulfonic acid ionomers (PFSAs) induce significant mass-transport limitations in proton exchange membrane fuel cell catalyst layers due to their semicrystalline PTFE-based matrix. We present a novel PFSA with an amorphous perfluorinated matrix, which vastly improves gas permeability, reduces transport resistance, and improves catalyst utilization in functional catalyst layers.

Can Minerals in the Earth’s Lower Mantle Store Water?
Earth is considered a watery planet, simply by virtue of the fact that 71% of its surface is covered by oceans. But researchers have discovered that, in the massive volume of material in Earth’s interior, minerals can serve as an important water reservoir, providing a new perspective on our planet’s water budget.

Water Improves Material’s Ability to Capture CO2
With the help of the ALS, researchers from UC Berkeley and ExxonMobil fine-tuned a material to capture CO2 in the presence of water. The parties have applied for a patent on the material, which was developed for use on the relatively humid flue gases emitted by certain natural gas power plants, a cleaner-burning alternative to coal.

ALS Reveals Vulnerability in Cancer-Causing Protein
A promising anticancer drug, AMG 510, was developed by Amgen Inc. with the help of novel structural insights gained from protein structures solved at the ALS. AMG 510, which is currently in phase II clinical trials for efficacy, targets tumors caused by mutations in the KRAS protein, one of the most common causes of cancer. Read more »
