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

Researchers Confirm New 2D Topolgical Insulator

Researchers have established that a particularly stable form of WTe2 is a two-dimensional topological insulator, confirming recent predictions. The findings should provide new opportunities for fundamental studies of topological phenomena and for next-generation spintronic applications. ... Read more »

CO Adsorption on Pd(100) Studied by Multimodal Ambient Pressure X-Ray Photoelectron and Infrared Reflection Absorption Spectroscopies

The first combined infrared spectroscopy and ambient-pressure XPS study was demonstrated at Beamline 11.0.2. The in situ vibrational and core-level spectroscopies in the Torr pressure range offer complementary information on the properties of surfaces and adsorbates while closing the pressure gap between laboratory measurements and applications.  The multimodal spectroscopy also allowed the identification of the C 1s binding energy and quantification of an uncommon atop CO species on a Pd(100) surface. ...

Microbes Linked to Drier Human Skin

Genetic analyses and infrared studies have found that archaea, a type of microbe commonly found in extreme environments, are also found on human skin. The results suggest that an increase in archaea is linked to reduced skin moisture and that they are most abundant in subjects younger than 12 and older than 60. ... Read more »

Project Director’s Update on ALS-U

In the last year since ALS-U received approval of mission need (CD-0) from DOE, we’ve made a lot of progress. I’d like to share some updates with you as well as offer opportunities for our users to engage in the next phases of the project. ... Read more »
