Physical Review Letters Nickel-78 is a 'doubly magic' isotope, supercomputing calculations confirm
'Doubly magic' atomic nuclei have greater stability than their neighbors thanks to having shells that are fully occupied by both protons and neutrons. Theoretical physicists at Oak Ridge National Laboratory recently used Titan, America's most powerful supercomputer, to compute the nuclear structure of nickel-78 and found that this neutron-rich nucleus is indeed doubly magic. The results may improve understanding of the origin, organization and interactions of stable matter.

Journal of the American Chemical Society Unraveling the science behind biomass breakdown
Using the Titan supercomputer, an ORNL team created models of up to 330,000 atoms that led to the discovery of a THF-water cosolvent phase separation on the faces of crystalline cellulose fiber.

Physical Review A Sensors -- quantum leap
By exploiting some exotic quantum states, researchers have conceptually designed a sensor that features unparalleled sensitivity. In a paper published in Physical Review A, Ali Passian of Oak Ridge National Laboratory and George Siopsis of the University of Tennessee describe a photon-sensing scheme for a detector that would behave much like a miniature trampoline.
Public Release: 5-Oct-2016 Samsung licenses ORNL transparent superhydrophobic glass coatings for electronic devices
Samsung Electronics has exclusively licensed optically clear superhydrophobic film technology from the Department of Energy's Oak Ridge National Laboratory to improve the performance of glass displays on smartphones, tablets and other electronic devices.
ORNL's development of a transparent coating that repels water that carries away dust and dirt, reduces light reflection and resists fingerprints and smudges resulted from approximately three years of superhydrophobic research on glass-based coatings.
Public Release: 4-Oct-2016 GreenWood Resources licenses ORNL invention to boost biofuel yield
GreenWood Resources has licensed an Oak Ridge National Laboratory technology based on the discovery of a gene in poplar (Populus trichocarpa) that makes it easier to convert poplar trees into biofuels. GreenWood, a global timberland investment and asset management company based in Oregon, plans to commercialize the technology to select and breed better varieties of poplar with less lignin content, which simplifies the conversion process and ultimately lowers the overall costs of biofuel production.

Advanced Electronic Materials Complex materials can self-organize into circuits, may form basis for multifunction chips
Researchers studying the behavior of nanoscale materials at the Department of Energy's Oak Ridge National Laboratory have uncovered remarkable behavior that could advance microprocessors beyond today's silicon-based chips.
The study, featured on the cover of Advanced Electronic Materials, shows that a single crystal complex oxide material, when confined to micro- and nanoscales, can act like a multi-component electrical circuit.
Public Release: 4-Oct-2016 ORNL licenses rare earth magnet recycling process to Momentum Technologies
The Department of Energy's Oak Ridge National Laboratory and Momentum Technologies have signed a non-exclusive licensing agreement for an ORNL process designed to recover rare earth magnets from used computer hard drives.
The patent-pending process developed as part of DOE's Critical Materials Institute is designed to economically recover large amounts of magnets made using neodymium--a rare earth element that is mined outside the United States.

Nanoscale Electron beam microscope directly writes nanoscale features in liquid with metal ink
Scientists at the Department of Energy's Oak Ridge National Laboratory are the first to harness a scanning transmission electron microscope to directly write tiny patterns in metallic 'ink,' forming features in liquid that are finer than half the width of a human hair. The automated process is controlled by weaving a STEM instrument's electron beam through a liquid-filled cell to spur deposition of metal onto a silicon microchip. The patterns created are nanoscale.

Science Advances Study yields new knowledge about materials for ultrasound and other applications
Scientists at the Department of Energy's Oak Ridge National Laboratory and their research partners have used neutron scattering to discover the key to piezoelectric excellence in the newer materials, which are called relaxor-based ferroelectrics. (A ferroelectric material has electrical polarization that is reversed by application of an electric field.) Their findings, published online in the journal Science Advances, may provide knowledge needed to accelerate the design of functional materials for diverse applications.

SC16: The International Conference for High Performance Computing, Networking, Storage and Analysis Streamlining accelerated computing for industry
In an effort to modernize CFD, a group of Imperial College researchers has developed new open-source software called PyFR, a Python-based application that combines highly accurate numerical methods with a highly flexible, portable, and scalable code implementation that makes efficient use of accelerators. Industry adoption of the code could allow companies to better exploit petascale computing to understand long-standing fluid flow problems, unsteady turbulence in particular.
Public Release: 16-Aug-2016 Energy Department to invest $16 million in computer design of materials
The US Department of Energy announced today that it will invest $16 million over the next four years to accelerate the design of new materials through use of supercomputers.
Two four-year projects -- one team led by DOE's Oak Ridge National Laboratory, the other team led by DOE's Lawrence Berkeley National Laboratory -- will take advantage of superfast computers at DOE national laboratories by developing software to design fundamentally new functional materials.
