After a first-year ramp-up for testing and tuning components, COSMIC is now operating at the ALS. The beamline brings together unique capabilities to measure the properties of materials at the nanoscale, and scientific results from its earliest experiments are expected to be published later this year. ...

The electronic structure of a stacked 2D material was tuned by in situ electron doping, resulting in a large increase in the splitting of two valence bands. Stacked 2D materials possess an array of tunable properties that are expected to be important for future applications in electronics and optics. ... Read more »
A new study suggests that water may be more common than expected at extreme depths approaching 400 miles and possibly beyond—within Earth’s lower mantle. The study explored microscopic pockets of a trapped form of crystallized water molecules in a sampling of diamonds from around the world. ... Read more »
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. ... Read more »
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.
