Tracking the Elusive QOOH Radical

For the first time, researchers directly observed QOOH molecules, a class of highly reactive molecules at the center of the web of ignition chemistry reactions. The data generated will improve the fidelity of combustion models used to create cleaner and more efficient cars and trucks. More>

Enhanced Microscopic Resolution for Improved Diagnostics

Simple, low-cost techniques developed by ALS affiliate Laura Waller are giving standard optical microscopes — and even smartphones — powerful new ways to see the minuscule. LED lights in a custom-built device boost resolution by making several microphotographs of a cell sample while changing only the angle of the lighting. More>

Investigating Buried Interfaces in Ferroelectric Materials

Researchers at Berkeley Lab and the Soleil Synchrotron in Paris have developed a new technique for investigating buried interfaces in ferroelectric materials. The new technique provides key information that should advance the exploitation of the unique properties of ferroelectric materials for encoding information. More>

ALS X-Rays Shine a New Light on Catalysis

Electrocatalysts are responsible for expediting reactions in many promising renewable energy technologies. A team of Berkeley Lab and Stanford researchers used x-rays at the ALS in a novel way to observe the behavior of electrons in metal oxide electrocatalysts. What they learned has upended long-held scientific understanding of how these catalysts work. More>

What Goes Up, Must Come Down (and Sometimes Gets Stuck)

High-pressure experiments at Beamline 12.2.2 on ferropericlase—the presumed weakest mineral found in the Earth’s lower mantle—help explain why subducted slabs of Earth’s crust stall at a depth of around 1000 km.

On-Demand X-Rays at Synchrotron Light Sources

The technique allows ALS users to access to the X-ray beams they want without affecting beams
for other users. The technique displaces and routes a single electron bunch from the multi-bunch electron beam in the ALS’s storage ring so that only X-ray light from this displaced bunch reaches the experiment. More>

$2.4 Million From Moore Foundation For New Technique Developed at ALS

A novel X-ray scattering concept by researchers at the Advanced Light Source is receiving support from the Gordon and Betty Moore Foundation in the amount of $2.4 million. The lead investigator is ALS Division Deputy Zahid Hussain, with ALS Director Roger Falcone acting as co-PI on the project. More>

A Fullerene That Breaks the Rules

Scientists used small-molecule x-ray crystallography to verify and characterize the first non-functionalized fullerene with a heptagonal ring in the cage. This new molecule changes the definition of a classical fullerene and expands the range of structural possibilities for endohedral fullerenes. More>
