Using neutron imaging to improve energy efficiency

(Physorg.com) Neutron scientists at Oak Ridge National Laboratory are partnering with industry to enhance engine and commercial cooling technologies in hopes of making improvements that will optimize fuel and energy efficiency. Hassina Bilheux, a physicist and a neutron imaging scientist at ORNL, uses beam line CG-1D at the High Flux Isotope Reactor (HFIR) to image automobile engine system components, two-phase fluid components in commercial cooling systems, and electrodes used for lithium batteries...1/14

Blood-flow research at the petascale

(Physorg.com) A group of Brown University researchers is attempting to create its own three-dimensional innovation in navigation, but instead of mapping interstates and city blocks, the team is charting the vascular highway of the human body—the arterial tree..."High-performance computing makes realistic modeling of vascular and hematological diseases, from a whole organ down to protein-level representation of red blood cells, a possibility," said [George] Karniadakis, discussing the research conducted on the Cray XT5 system Kraken, the world's fastest academic supercomputer, located at the National Institute for Computational Sciences, a National Science Foundation-funded supercomputing center managed by the University of Tennessee and located at Oak Ridge National Laboratory...1/14

Neighbor lends a hand: Spallation Neutron Source's tool to probe ITER's superconducting cable

(R&D) Scientists and engineers at the Spallation Neutron Source at Oak Ridge National Laboratory are working with the U.S. ITER Project Office at ORNL, the Japanese Atomic Energy Agency and the ITER Organization to resolve issues with a critical component of the experimental fusion energy facility ITER. The VULCAN Engineering Diffractometer at SNS is being used to examine superconducting cables for ITER's central solenoid magnet, which induces the electrical current needed to confine and shape the plasma inside the reactor...1/14


87-year-old retired Oak Ridge chemist honored

(AP) A man described as "the face of Oak Ridge" has become the East Tennessee Economic Council's latest "Muddy Boot" inductee. Eighty-seven-year-old William Jenkins Wilcox Jr., also known as Bill, is a retired chemist at the Y-12 National Security Complex. Wilcox is now the official historian for the city and has devoted his last 10 years to helping tell the story of Oak Ridge and its role in World War II. The Muddy Boot Award is named after the sea of mud that was Oak Ridge in its very early construction years from 1942 to 1945...1/18
