Stanford and SLAC Professor Tony HeinzSLAC's Tony Heinz will lead work on novel nanoscale materials

Tony Heinz, a scientist known for exploring the properties of nanoscale materials and developing important new tools for that exploration, has joined DOE’s SLAC National Accelerator Laboratory as a professor of photon science and Stanford University as a professor of applied physics. He will also lead the SLAC Chemical Sciences Division.

While his position became official in January, he will spend the next few months wrapping up his research at Columbia University, where he has been the David Rickey Professor of Physics and Electrical Engineering, and moving operations into lab space being readied on the Stanford and SLAC campuses.

“As someone who grew up in Northern California and attended Stanford and Berkeley, I am really looking forward to being back in the Bay Area,” Heinz said. “It’s a beautiful part of the world, a very exciting one in terms of science and technology, and also one with family and friends. I am delighted to have the opportunity to join the research activities at SLAC and Stanford.”

The Large Synoptic Survey Telescope, whose construction is led by DOE’s SLAC National Accelerator Laboratory, is currently in the advanced design phase.  Placed in Cerro Pachon, Chile, it will enable the world's largest imaging survey, taking repeated images of the southern sky beginning in 2020.

"LSST will truly be a next-generation survey: It will surpass preceding surveys in terms of data size in its first few months of operation," said University of Pennsylvania astrophysicist Bhuvnesh Jain, spokesperson for the Dark Energy Science Collaboration of the LSST.

Innovative DESC software, developed at DOE’s Fermi National Accelerator Laboratory in collaboration with other institutions, will enable scientists to explore the many astronomical mysteries that the LSST will open up. At SC14, the supercomputing conference held in November, Fermilab scientists achieved a milestone with a successful demonstration run of the DESC analysis framework software.

  • NREL software tool a boon for wind industry

    In the Energy Systems Integration Facility (ESIF) Insight Center, NREL Senior Engineer Pat Moriarty, left, and NREL Senior Engineer Paul Fleming review velocity (blue) and turbulence (yellow) in a simulation of the Lillgrund Wind Farm in Denmark. Photo by Dennis Schroeder, NREL Wind energy is blowing away skeptics—it's so close to achieving cost parity with fossil fuels that just a little extra efficiency is all that is likely needed to push it into the mainstream and past the Energy Department's goal of 20% wind energy by 2030.

    That extra efficiency may be realized with the help of a software tool built by the Energy Department's National Renewable Energy Laboratory (NREL). It's called Simulator for Wind Farm Applications (SOWFA), and it can calculate how undulating ground, whipping blades, surface temperatures, and other variables alter the air flow and energy production at wind farms.

  • DARPA taps LLNL to restore touch to amputees

    Lawrence Livermore National Laboratory Engineer Sat Pannu and his Neural Tech Group research team are developing wireless electronic packages for HAPTIX called smart packages. These packages would contain electronics that record and stimulate the peripheral nervous system to control movement and sensation in a patient’s prosthetic hand. The Defense Advanced Research Projects Agency (DARPA) recently selected Lawrence Livermore National Laboratory (LLNL) to join a collaborative research team that intends to build the world’s first neural system to enable naturalistic feeling and movements in prosthetic hands.

    Known as Hand Proprioception and Touch Interfaces (HAPTIX), the program seeks to provide wounded service members with dexterous control over advanced prosthetic devices that substitute for amputated hands. If successful, HAPTIX intends to give patients the psychological benefit of having natural sensation in their prosthetic hands and reduction of “phantom limb” pain, a sensation some amputees can feel despite the removal of a limb.

  • NETL invents improved oxygen carriers

    Oxygen carriers are similar in texture to sand. The oxygen carrier pictured here blends magnesium oxide and hematite. One of the keys to the successful deployment of chemical looping technologies is the development of affordable, high performance oxygen carriers. One potential solution is the naturally-occurring iron oxide, hematite. “Hematite is pretty cheap,” says Doug Straub, Technical Coordinator for the National Energy Technology Laboratory’s Chemical Looping Combustion (CLC) projects and the just-completed Industrial Carbon Management Initiative (ICMI). “You just dig it out of the ground and run it through a screen.” That affordability makes hematite attractive as an oxygen-carrier material, but high performance at the conditions imposed by the chemical looping process is also important. Researchers at the DOE lab are investigating how to enhance hematite-based oxygen carriers so they can stand up to high reactor temperatures. Oxygen carriers also need to be resilient in the face of frequent impacts with reactor walls, with each other, and (in coal-burning reactors) with coal particles. Researchers are also improving oxygen carriers so that they more completely combust the fuel.

    Their work has paid off. Dr. Ranjani Siriwardane (who leads the CLC oxygen carrier research) and Dr. Duane Miller (a chemical engineer at NETL) have invented an oxygen carrier that pairs magnesium oxide with hematite. During a pilot-scale run through NETL’s fluidized bed reactor last year, their carrier showed better performance than carriers that contained just natural hematite.

  • Brookhaven dedicates 'brightest beacon at the frontiers of discovery'

    U.S. Department of Energy Secretary Ernest Moniz (right) touring NSLS-II with Project Director Steve Dierker and Lab Director Doon Gibbs. From the floor to the rafters, the world's most advanced synchrotron light source was filled with hundreds of people—including U.S. Department of Energy (DOE) Secretary Ernest Moniz, U.S. Senator Chuck Schumer, U.S. Representatives Lee Zeldin and Kathleen Rice, and a number of other distinguished guests—who gathered as Secretary Moniz dedicated the National Synchrotron Light Source II (NSLS-II) at Brookhaven Lab on Feb. 6.

    NSLS-II is a $912-million DOE Office of Science User Facility that produces extremely bright beams of x-ray, ultraviolet, and infrared light. With x-rays 10,000 times brighter than its predecessor's, researchers at NSLS-II will examine a wide range of materials, including superconductors and catalysts, geological samples, and biological proteins to accelerate advances in energy, environmental science, and medicine.
