August 13, 2014Raloxifene, a treatment for decreasing fracture risk in osteoporosis, works only partially by suppressing bone loss. Studies at the U.S. Department of Energy′s Advanced Photon Source revealed an additional mechanism underlying raloxifene action, providing an explanation for how this drug can achieve equivalent clinical benefit. These data, together with complementary techniques, help define a novel mechanism by which raloxifene increases inherent bone toughness.
August 5, 2014Measurements carried out at the U.S. Department of Energy′s Advanced Photon Source, coupled with state-of-the-art density functional theory simulations reveal that strong acids, such as hydrochloric acid, form counter-ion pairs in solution across all concentration, a result that had not been seen in gas-phase studies. The discovery suggests that it is not simply the release of protons — hydrogen ions — that is important for the properties of acids.
July 10, 2014Perovskites entice materials scientists with their ferroelectricity, ferromagnetism, catalytic activity, and oxygen-ion conductivity. Perovskites could be vastly improved by assembling them into thin films, but no one understood why thin films beat out bulk materials. Researchers working the U.S. Department of Energy′s Advanced Photon Source at Argonne National Laboratory used a groundbreaking approach to tease apart the thin-film structure and chemistry layer by layer and found that, instead of having a uniform distribution of elements, there were drastic differences in composition between the thin-film layers, an observation may help researchers design thin-film perovskites with enhanced activity and stability.
July 9, 2014Scientists using the U.S. Department of Energy′s Advanced Photon Source have demonstrated a conceptually new ultra-high-resolution inelastic x-ray scattering spectrometer able to provide valuable insight into how a material transforms from liquid to glass, one of the great mysteries of condensed matter physics. Understanding this process could shed new light on condensed matter theory and have practical applications such as the design of new drugs.
July 7, 2014Researchers working at the U.S. Department of Energy′s Advanced Photon Source at Argonne National Laboratory applied intense pressure to a compound of gadolinium and silicon, collecting information about a material well-suited to computer memory and magnetic sensors, and opening a new window into the complex lives of electrons under stress.
May 27, 2014Multiferroics are materials that exhibit a ferroelectric and magnetic order simultaneously. These orders have been the building blocks for technologically and economically important applications such as ferroelectric memory and spintronics, and present opportunities for efficient electric-field control of magnetism on ultrafast time scales. New research at the Universität Potsdam and at the U.S. Department of Energy Office of Science′s Advanced Photon Source is providing a better understanding of how these new properties come about and how best to harness them.
January 7, 2014Kwang-Je Kim of the Advanced Photon Source has been named the recipient of the 2014 Robert R. Wilson Prize for Achievement in the Physics of Particle Accelerators,
December 18, 2013Katherine Harkay of the Accelerator Systems Division has been elected to Fellowship in the American Physical Society for “significant contributions to the understanding of the physics of electron cloud effects and the experimental investigation and understanding of collective effects, as well as for playing leading roles in development of photocathodes and superconducting undulator technology."
December 9, 2013Peter Chupas of the Advanced Photon Source has been named one of the Chicago “40 Under 40: 2013” by Crain’s Chicago Business.
