ALS

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-rays and infrared, for scientific research and technology development in a wide range of disciplines.

A New Path to Carbon Dioxide Transformation

Combining ALS experiments with quantum-mechanical calculations, scientists found dramatic differences in how carbon dioxide (CO2) reactions begin on silver as opposed to copper. Both metals help transform CO2—a greenhouse gas—into more useful forms, and this new atomic-level data could help make the process more efficient. Read more »

Chiral Crystals Give Rise to Topological Conductors

Researchers have discovered materials whose chiral crystal structures produce chirality in their electronic behavior. These topological conductors retain their unique electronic properties regardless of defects and open new possibilities in materials research. Read more »

Infrared Light Reveals Microstripes at Insulator-Metal Transition

In this study of a current-driven insulator-to-metal transition, a distinctive stripe pattern develops between the insulating and metallic phases. The work reveals remarkable new features of electrically induced insulator-to-metal transitions in materials with potential applications in energy-efficient memory and transistor devices.

Electric Skyrmions Charge Ahead for Next-Generation Data Storage

Researchers have observed chirality for the first time in polar skyrmions in a material with reversible electrical properties. The combination of polar skyrmions and these electrical properties could one day lead to applications such as more powerful data storage devices that hold information even after a device has been powered off.
