16-Nov-2015 X-ray microscope reveals 'solitons,' a special type of magnetic wave
Researchers used a powerful, custom-built X-ray microscope at the Department of Energy's SLAC National Accelerator Laboratory to directly observe the magnetic version of a soliton, a type of wave that can travel without resistance. Scientists are exploring whether such magnetic waves can be used to carry and store information in a new, more efficient form of computer memory that requires less energy and generates less heat.

3-Nov-2015 A record-setting way to make transparent conductors: Spread them like butter on toast
Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have shown they can make flexible, transparent electrical conductors with record-high performance for use in solar cells, displays and other devices by spreading polymers on a clear surface with a tiny blade, like a knife spreading butter on toast.
2-Nov-2015 Cold electronics help scientists spot elusive 'ghost' particles
Nestled inside the massive MicroBooNE detector, part of a new neutrino experiment just getting underway at the US Department of Energy's (DOE) Fermi National Accelerator Laboratory, lie 50 circuit boards packed with custom-built microelectronics. These circuits were designed by engineers at DOE's Brookhaven National Laboratory to operate while immersed in liquid argon, a cryogenic liquid that boils at a biting -186 degrees Celsius or -303 degrees Fahrenheit.
29-Oct-2015 Scientists get first glimpse of conductivity that could break size barriers for memory
Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have made the first direct images showing that electrical currents can flow along the boundaries between tiny magnetic regions of a material that normally doesn't conduct electricity. The results could have major implications for magnetic memory storage.
26-Oct-2015 Nanoscale, multidimensional artificial magnet created
Scientists from Los Alamos National Laboratory, in collaboration with a group at the University of Illinois at Urbana-Champaign, the Lawrence Berkeley National Laboratory's Advanced Light Source and with other researchers nationwide, have realized a nanoscale, artificial magnet by arranging an array of magnetic nano-islands along a geometry that is not found in natural magnets. Their paper 'Emergent reduced dimensionality by vertex frustration in artificial spin ice' appears on the journal Nature Physics' website today.
22-Oct-2015 Stanford and SLAC celebrate Arthur Bienenstock
Arthur 'Artie' Bienenstock, professor emeritus at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory, was honored with an all-day symposium in recognition of his outstanding contributions to science, academia, graduate student education and US science policy.
15-Oct-2015 W80-4: Sandia California works on nuclear weapon Life Extension Program
Sandia National Laboratories is performing a Life Extension Program on the W80-4 nuclear weapon. The Life Extension Program is refurbishing the W80 warhead with replacement components for aging technology and components that have limited lifespans. Much of the work is being done at Sandia's California site.
13-Oct-2015 Ming Yi awarded L'Oréal USA For Women in Science Fellowship
Former Stanford University graduate student Ming Yi has been awarded the $60,000 L'Oréal USA For Women in Science Fellowship, which is given to five US-based women each year as part of an effort to raise awareness of women's contributions to science and identify exceptional female researchers to serve as role models.
7-Oct-2015 Laser spectroscopy of ultrathin semiconductor reveals rise of 'trion' quasiparticles
Scientists at the Department of Energy's Oak Ridge National Laboratory used ultrafast laser spectroscopy at the Center for Nanophase Materials Sciences to demystify the dynamics of the negative trions. They explored the behavior of the charged quasiparticle in a two-dimensional semiconductor that is an excellent absorber of sunlight. Their insights, published in the journal Physical Review B, may prove important for advancing technologies for solar energy and quantum computing.
5-Oct-2015 DOE announces funding for new center for computational materials sciences at Brookhaven Lab
The US Department of Energy (DOE) has announced $12 million in funding over the next four years for a new Center for Computational Design of Functional Strongly Correlated Materials and Theoretical Spectroscopy at Brookhaven National Laboratory and Rutgers University. Center scientists will develop next-generation methods and software to accurately describe electronic properties in complex strongly correlated materials, as well as a companion database to predict targeted properties with energy-related application to thermoelectric materials.
25-Sep-2015 Feng Lin wins Spicer Award for smart window, battery research
Feng Lin, a former postdoctoral researcher at Lawrence Berkeley National Laboratory, has been selected to receive the annual William E. and Diane M. Spicer Young Investigator Award for X-ray experiments at the Department of Energy's SLAC National Accelerator Laboratory that led to new approaches in the design of energy-efficient, color-changing 'smart' windows and high-capacity lithium-ion batteries.
23-Sep-2015 Techniques could create better material, design in high-consequence uses
Sandia National Laboratories is studying additive manufacturing and its potential for high-consequence applications. Two aspects of that effort are to understand both the properties of newly formed materials and how to design to get just what's needed without over-designing.
14-Sep-2015 Scientists use lasers to simulate shock effects of meteorite impact on silica
Scientists used high-power laser beams at the Department of Energy's SLAC National Accelerator Laboratory to simulate the shock effects of a meteorite impact in silica, one of the most abundant materials in the Earth's crust. They observed, for the first time, its shockingly fast transformation into the mineral stishovite -- a rare, extremely hard and dense form of silica.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
