Experiments retrace the steps leading to the creation of complex hydrocarbons in space, showing pathways to forming 2D carbon-based nanostructures in a mix of heated gases. The study could help explain the presence of pyrene, a polycyclic aromatic hydrocarbon, and similar compounds in some meteorites. Read more »

Scientists have discovered a novel chemical state of the element manganese. This chemical state, first proposed about 90 years ago, enables a high-performance, low-cost sodium-ion battery that could quickly and efficiently store and distribute energy produced by solar panels and wind turbines across the electrical grid.

Join the ALS Users’ Executive Committee, ALS staff, and the ALS-U project team for the next online user forum, Thursday, March 1 at 10 a.m. PT. The agenda will include a UEC welcome and updates, opportunities for magnetism, spintronics, and quantum materials research, and an update on COSMIC microscopy. Questions from the virtual audience are welcome. Read more »
X-ray absorption spectroscopy and other techniques were used to measure the organic chemical components in a pair of meteorites that crashed to Earth in 1998. The study treads new ground in solar system history and asteroid geology, surfacing exciting possibilities for the existence of life elsewhere in Earth’s neighborhood.

Researchers directly observed the formation of highly oxygenated molecules—the elusive products of auto-oxidation reactions relevant to combustion and atmospheric chemistry. A better understanding of auto-oxidation mechanisms could lead to better engines, less air pollution, and improved climate models.

After 18 years working in various divisions at Berkeley Lab, Jeremy Coyne recently returned to the ALS, where his Lab career first started. Jeremy has taken on the role of senior business manager at the ALS, overseeing and managing the ALS Business Support Team and the division’s entire financial portfolio. Read more »
Researchers designed and fabricated a nanomagnet array in which competing (“frustrated”) magnetic interactions can be directly tuned. Frustrated interactions are key to a wide range of phenomena, from protein folding and magnetic memory to fundamental studies of emergent exotic states.

Parrotfish chew on coral, producing hundreds of pounds of sand each year. Mapping the microstructure of parrotfish teeth, scientists found bundles of crystals interwoven like chain mail. The results provide a blueprint for creating ultra-durable materials for mechanical components that undergo repetitive contact, movement, and abrasion. Read more »
On January 22, the third in a series of online ALS user forums was held on the Advanced Light Source Upgrade (ALS-U) project. Presentations included an overview of the project, an update on the ALS-U beamline selection process, and ideas for the future of soft matter research at the ALS. The next forum will be held Thursday, March 1, at 10 a.m. PT. Read more »
Beamline 12.2.1, the successor to Beamline 11.3.1, achieved first light on December 21, 2017. This new small-molecule crystallography beamline, which will take over the scientific program of 11.3.1, features a number of improvements that will significantly expand the capabilities available to users.
