Researchers have published a landmark study that used both crystallography and SAXS to validate computationally designed structures of novel proteins with repeated motifs. The results show that the protein-folding universe is far larger than realized, opening up a wide array of new possibilities for biomolecular engineering. Read more »

Direct Observation of Localized Radial Oxygen Migration in Functioning Tantalum Oxide Memristors
As information bits of 0s and 1s are stored in crosspoint tantalum oxide memristors, or resistive random access memory (RRAM) cells, nanoscale-resolution in operando x-ray transmission spectromicroscopy is used to directly observe oxygen migration and clustering, revealing an important operation and failure mechanism of RRAM, a frontrunner technology for next-generation computer memory.

Missing Oxygen Atoms Are Key to Robust Spintronic Material
Researchers studied In2O3:Fe, a promising spintronic material, to determine what leads to its surprisingly robust magnetic properties, how to optimize it, and what to look for in other candidate spintronics materials. Read more »
Superlattices Patterned by Polymers
Scientists have shown that self-assembled superlattices, made up of nanoparticles with polymer chains grafted onto their surfaces (“hairy nanoparticles,” or polymer “brushes”), can be tailored to exhibit desired characteristics for applications ranging from nano- to biotechnology. Read more »
On the Way to Unlimited Energy
With the help of four different ALS beamlines, scientists were able to understand and improve the morphology of the main device structure in organic photovoltaic cells. Read more »
Improving Anti-Influenza Medications
Protein crystallography at ALS Beamline 8.3.1 helped scientists understand the M2 proton-channel structure from the influenza A virus, an understanding that is needed to design better anti-influenza medications. Read more »
Cobber Lam, ALS Systems Administrator
Cobber Lam started working at Berkeley Lab 10 years ago as a student assistant, while attending college at Cal State East Bay. Within two months, he was assigned to the ALS and has stayed put ever since. He used to be matrixed via IT, but last year he became a direct ALS employee. ALS IT support is divided between Lam and Tim Kellogg, with Lam being more forward-facing, dealing with users and staff, and Kellogg working on the back-end mostly with controls and operations groups.

Manganese Reduction-Oxidation Drives Plant Debris Decomposition
ALS research has shown that manganese reduction-oxidation (redox) reactions are an important factor in controlling the rate of plant debris decomposition. Understanding the role of manganese will help build better models to predict how litter decomposition rates—and thus nutrient cycling and the ecosystem carbon balance—may behave in future climate scenarios.

Porous-Framework Electrocatalysts Are Key to Carbon Dioxide Conversion
Researchers have made significant headway in the quest to convert CO2 into valuable chemical products such as fuels, pharmaceuticals, and plastics. Recent work at the ALS has shown MOFs and COFs as a valuable new class of CO2 reduction catalysts. Read more »
Call for Proposals to Host Workshops at the 2016 ALS User Meeting
ALS users are invited to submit proposals to host workshops at the upcoming ALS User Meeting to be held October 3-5, 2016 at Berkeley Lab. Students are also encouraged to suggest workshop topics of particular interest to them.
