ALS COVID status update. Visit this link for user-related information. See here for staff-only information.

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.

Experimental Drug Targets HIV in a Novel Way

Researchers from Gilead Sciences Inc. solved the structure of an experimental HIV drug bound to a novel target: the capsid protein that forms a shield around the viral RNA. The work could lead to a long-lasting HIV treatment that overcomes the problem of drug resistance and avoids the need for burdensome daily pill-taking. Read more »PPT-icon-35 PDF-icon-35

Yang Ha, Chemistry and Materials Postdoc

Synchrotron science is in Yang Ha’s DNA. After getting his PhD from Stanford/SSRL, he joined the ALS in 2018 to study batteries and has branched out to theoretical computation and machine learning. He has also learned useful skills for sharing cutting-edge research with a broader audience. Read more »

Detecting Phonon Overtones in Correlated Materials

Resonant inelastic x-ray scattering (RIXS) has recently been shown to be a promising technique for studying electron–phonon coupling in correlated materials. When a photoexcited electron interacts with phonons during decay, it shows up in the RIXS spectra as clear phonon overtones: higher-order excitations that appear as ripples in intensity. Read more »

Stress-Induced Structural Transformations in Gold Nanocrystals

Metallic nanocrystals are widely used in catalysis, electronics, photonics, and sensing applications, but our understanding of their stability under operational stresses is limited. These studies of gold nanocrystals at high pressures found that large-scale structural transformation is possible and must be considered at the nanoscale. Read more »
