Resonant soft x-ray diffraction studies of a cuprate high-temperature superconductor revealed a 3D, long-range charge order—the first of its kind ever reported in a cuprate—that competes with superconductivity. A better understanding of such phenomena could help in the design of more robust superconductors with higher transition temperatures. Read more »

An Atomic-Level Understanding of Copper-Based Catalysts
Copper-based catalysts are widely used in chemical industries to convert water and carbon monoxide to hydrogen, carbon dioxide, and methanol. There are theoretical models used to explain this reaction, but a complete understanding of the process has been lacking. However, recent research at the ALS has shed light on the process, giving scientists key data about how copper-based catalysts function at the atomic level. Read more »
Reducing Plant Lignin for Cheaper Biofuels
Scientists have identified and validated a novel approach to reducing lignin in plants by tweaking a key lignin enzyme. Their technique could help lower the cost of converting biomass into carbon-neutral fuels to power cars and other sustainably developed bio-products. Read more »
Shutting Out Ebola and Other Viruses
Researchers have used protein crystallography at the ALS to understand how a drug molecule that has shown some efficacy against Ebola in mice inactivates a membrane protein, called TPC1, used by viruses to infect host cells. Read more »
Driving Skyrmions Along a Racetrack
Researchers have demonstrated the ability to generate stable skyrmion lattices and to drive trains of individual skyrmions by short current pulses along a magnetic racetrack at speeds exceeding 100 m/s, as required for spintronic applications. Read more »
A New Universal Parameter for Superconductivity
Scientists have been researching high-temperature (high-Tc) superconductors for decades with the goal of finding materials that express superconducting capabilities at room temperature, which would be a requirement for practical and cost-effective applications. The newest materials to gain scientific interest are iron-based superconductors, and the latest research from the ALS on these materials indicates a new factor that determines their superconductivity.
