Toyota has been working at the ALS for a few years now to gain deeper insight into the chemistry of electrolytes for use in magnesium-ion batteries. The hope is that the research eventually leads to a fully developed magnesium-based battery technology that would replace lithium-ion batteries with essentially twice the energy in the same volume. Toyota hopes to move toward this goal more quickly through a new collaborative research project at the ALS and the Molecular Foundry. Read more »
ALS Work Using XAS
In x-ray absorption spectroscopy (XAS), the incident x-ray energy is tuned over a range that will excite core-level electrons. Sharp increases in absorption occur at specific energies, characteristic of the absorbing element. The resulting spectra probe the elemental composition as well as the chemical and electronic structure of the material.
IBM Probes Material Capabilities at the ALS
Vanadium dioxide, one of the few known materials that acts like an insulator at low temperatures but like a metal at warmer temperatures, is a somewhat futuristic material that could yield faster and much more energy-efficient electronic devices. Researchers from IBM’s forward-thinking Spintronic Science and Applications Center (SpinAps) recently used the ALS to gain greater insight into vanadium dioxide’s unusual phase transition.

Particles from Comet 81P/Wild 2 Viewed by ALS Microscopes
NASA’s $200-million, seven-year-long Stardust mission returned to Earth thousands of tiny particles snagged from the coma of comet 81P/Wild 2. Four ALS beamlines and the researchers using them were among the hundreds of scientists and dozens of experimental techniques in facilities around the world that contributed to the preliminary examination of the first samples.
