10-Feb-2017 Exploring mysteries on the surface
Ames Laboratory scientists Pat Thiel and Michael Tringides are explorers, discovering the unique properties of two-dimensional (2-D) materials and metals grown on graphene, graphite, and other carbon coated surfaces.
6-Feb-2017 Fermilab achieves milestone beam power for neutrino experiments
The US Department of Energy's Fermi National Accelerator Laboratory has achieved a significant milestone for proton beam power. On Jan. 24, the laboratory's flagship particle accelerator delivered a 700-kilowatt proton beam over one hour at an energy of 120 billion electronvolts.
1-Feb-2017 Simulations reveal the invisible chaos of superluminous supernovae
To better understand the physical conditions that create superluminious supernova, astrophysicists are running 2-D simulations of these events using supercomputers at the Department of Energy's National Energy Research Scientific Computing Center and the Lawrence Berkeley National Laboratory (Berkeley Lab) developed CASTRO code.
24-Jan-2017 The contradictory catalyst
One reason we can't bottle summer sunshine and save the solar energy for rainy days is that we don't have an efficient way to store it. Nature stores energy in chemical bonds, like when plants photosynthesize our food. Researchers are trying to design catalysts based on inexpensive metals to store energy like nature does.
12-Jan-2017 Fast track control accelerates switching of quantum bits
An international collaboration among physicists at the University of Chicago, Argonne National Laboratory, McGill University and the University of Konstanz recently demonstrated a new framework for faster control of a quantum bit -- the basic unit of information in yet-to-be created quantum computers -- in findings published online Nov. 28 in Nature Physics. Their experiments on a single electron in a diamond chip could create quantum devices less prone to errors when operated at high speeds.
11-Jan-2017 Sketching out magnetism with electricity
In a proof-of-concept study published in Nature Physics, researchers drew magnetic squares in a nonmagnetic material with an electrified pen and then 'read' this magnetic doodle with X-rays.
11-Jan-2017 Brookhaven National Laboratory's top-10 science successes of 2016
From advances in accelerators and experiments exploring the building blocks of matter and making medical isotopes to new revelations about superconductors, nanomaterials, and biofuels, 2016 was a year of accomplishment at the US Department of Energy's Brookhaven National Laboratory. Here are our Top-10 highlights.
9-Jan-2017 Anything to declare?
Scientists at Fermilab and CERN considered several options to transport fragile components of the CMS detector to Geneva. Their answer? Buy seats for the components on commercial airline flights.
9-Jan-2017 CERN ramps up neutrino program
CERN is accelerating its neutrino program by participating for the first time in an experiment (the Deep Underground Neutrino Experiment, hosted by Fermilab) not based at CERN itself.
6-Jan-2017 New director named to lead US Department of Energy's Jefferson Lab
Jefferson Science Associates, LLC today announced that Stuart Henderson will become the new Director of the US Department of Energy's Thomas Jefferson National Accelerator Facility in Newport News, Virginia. Currently serving as the Director of the Advanced Photon Source Upgrade Project at DOE's Argonne National Laboratory, Henderson will assume his responsibilities at Jefferson Lab on April 3.
4-Jan-2017 SLAC study: Light can switch on topological materials
Theoretical physicists at the Department of Energy's SLAC National Accelerator Laboratory used computer simulations to show how special light pulses could create robust channels where electricity flows without resistance in an atomically thin semiconductor.
3-Jan-2017 Ceramic matrix composites take flight in LEAP jet engine
Ceramic matrix composite (CMC) materials are tough, lightweight and capable of withstanding temperatures 300-400 degrees F hotter than metal alloys can endure. A quarter-century ago, the US Department of Energy began a program, led by DOE's Oak Ridge National Laboratory, to support US development of CMC materials. This year, LEAP, a new aircraft engine, became the first widely deployed CMC-containing product. CFM International, a 50/50 joint venture of Safran and GE, manufactures LEAP.
22-Dec-2016 For critical marine low clouds, a research and observation plan
Marine low clouds hover in the lowest couple of kilometers above the world's oceans. They produce little but drizzle, and could never match their deeper mid-continent cousin clouds for dramatic weather and severe storms. But marine low clouds are vastly important to the world's climate and energy balance.
21-Dec-2016 Filling in the nuclear data gaps
Berkeley Lab's Nuclear Data Group is conducting new experiments to address common data needs in nuclear medicine, nuclear energy and fusion R&D, security, and counterproliferation work.
21-Dec-2016 Honey, I shrunk the circuit
Sandia National Laboratories researchers have shown it's possible to make transistors and diodes from advanced semiconductor materials that could perform much better than silicon, the workhorse of the modern electronics world.
Scientists have witnessed the birth of atmospheric ice clouds, creating ice cloud crystals in the laboratory and then taking images of the process through a microscope, essentially documenting the very first steps of cloud formation. The team took time-lapse movies of the first few seconds when a particle attracts water vapor, forming ice crystals that become the core of icy cirrus clouds - the high, wispy clouds that act much like a blanket for our planet.
15-Dec-2016 Data storage upgrades future-proof ARM field sites -- for now
Throughout 2016, Cory Stuart, ARM's Site Data System (SDS) and Cyber Security Manager, and his team at Argonne National Laboratory have been methodically visiting all ARM sites to upgrade the data systems, especially storage capacity.
15-Nov-2016 After the Nobel Prize, what do you do for an encore?
Brownian motion makes it difficult for scientists to examine single protein molecules. W.E. Moerner, who had previously won the Nobel prize in chemistry, started tackling this issue in 2004. He and his team developed the ABEL Trap, which allows researchers to corral single molecules for study. Since then, scientists have used the trap to study proteins involved in photosynthesis and other major biological systems.
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.
