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 Bacterial Jigsaw Puzzle Is Solved

Bacterial microcompartments (BMCs) are hollow protein shells that encapsulate enzymes involved in bacterial metabolism. Crystallography studies have provided atomic-resolution views of a fully assembled BMC, revealing basic principles of shell construction for fighting pathogens or bioengineering applications. ...

In Situ Electrical Resistance and X-Ray Tomography Study of Copper–Tin Polymer Composites during Thermal Annealing

In situ electrical conductivity and x-ray tomography experiments were conducted on a conductive polymer composite containing polyvinylidene fluoride (PVDF) copolymer, copper (Cu), and tin (Sn) during thermal annealing. This study provides detailed insight into the morphological origins of the beneficial effect of thermal annealing on the electrical properties of conductive composites containing low melting metal fillers. ...

Hybrid LED Phosphors Combine Performance and Durability

Light-emitting diodes (LEDs) last a long time and are very energy efficient. However, white LEDs currently rely on phosphor materials doped with rare-earth elements (REEs) that are increasingly costly and in short supply. A new class of hybrid phosphor materials shows promise as REE-free alternatives. ... 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 ... Read more »
