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 Multifunctional Material with Electric-Field Control

Three distinct crystalline phases with different electronic, magnetic, and optical properties were reversibly induced in a material through the insertion and extraction of ions by an electric field at room temperature. Such multifunctional materials are desirable for many applications, from smart windows to spintronics. ... Read more »

Jinghua Guo, Senior Scientist

Jinghua Guo has been a part of the ALS since the early days. His original research focus is still one of his top interests now—studies of in situ capabilities of catalysts in gases and liquids and chemical processes. Guo also studies nanostructured materials, energy materials, and water and environmental sciences at Beamline 8.0.1 and also at 6.3.1.2. ... Read more »

The Ancient Roman Secret to Concrete Resilience in Seawater

Researchers used x-ray microdiffraction to trace the complex sequences of crystal growth in concrete from ancient Roman pier and breakwater sites. The results indicate that minerals continue to form over millennia as seawater percolates through, reinforcing the cementing matrix in a kind of regenerative process. ... Read more »

ALS Gives Intel a Closer Look at Microelectronic Packages

Intel, the world’s largest semiconductor chip maker, has been using the tomography capabilities at ALS Beamline 8.3.2 to image their microelectronic packages in 3D at high resolution with short throughput time, providing valuable information for both failure analysis and product development and proving to the industry as a whole that synchrotrons are an insightful tool for this type of imaging. ...
