Artificial Spin Ice Toggles Twist in X-Ray Beams on Demand

ALS studies helped scientists understand how a nanoscale magnetic lattice (an artificial spin ice) acts as a toggle switch for x-ray beams with spiral character. The findings represent an important step toward the development of a versatile new tool for probing or controlling exotic phenomena in electronic and magnetic systems.

Key to Cleaner Combustion? Look to the Stars

Researchers made the first real-time, lab-based measurement of free radicals reacting under cosmic conditions, prompting elementary carbon and hydrogen atoms to coalesce into primal benzene rings. The findings are key to understanding how the universe evolved with the growth of carbon compounds and could also help the car industry make cleaner combustion engines. Read more »

Angelic Lucero, Accelerator Operator Specialist

Working at the ALS started out as a summer job in college for Angelic Lucero—and then she never left. She gives us a glimpse into all the details our operators need to monitor and talks about efforts to help new people at the Lab access resources. Read more »

Scientists Uncover a Different Facet of Fuel-Cell Chemistry

Solid oxide fuel cells are a promising technology for cleanly converting chemical energy to electrical energy. To improve the efficiency of these devices, researchers studied a model electrode material in a new way—by exposing a different facet of its crystal structure to oxygen gas at operating pressures and temperatures.
