Newswise: Survey Delivers on Dark Energy with Multiple Probes
Released: 6-Sep-2019 1:05 PM EDT
Survey Delivers on Dark Energy with Multiple Probes
Department of Energy, Office of Science

The Dark Energy Survey has combined its four primary cosmological probes for the first time in order to constrain the properties of dark energy.

Newswise: Crossing the Great Divide Between Model Studies and Applied Reactors in Catalysis
Released: 5-Sep-2019 12:05 PM EDT
Crossing the Great Divide Between Model Studies and Applied Reactors in Catalysis
Department of Energy, Office of Science

A team devised a way to bridge the gap between two extremes. Using their approach, they can predict catalyst performance across a wider range of temperatures and pressures.

Newswise: Tiny, Sugar-Coated Sheets Selectively Target Pathogens

Getting Metal Under Graphite’s Skin
Department of Energy, Office of Science

Some metals need to be protected from the atmosphere. Exposure leads to damage that ruins their unique properties. Controllably forming metal islands just under the surface of graphite protects the metals. This allows these metals to take on new roles in ultrafast quantum computers. It also means new roles in magnetic, catalytic, or plasmonic materials.

Newswise: Atomically Packed Boundaries Resist Cracking
Released: 29-Aug-2019 1:05 PM EDT
Atomically Packed Boundaries Resist Cracking
Department of Energy, Office of Science

Scientists devised specialized X-ray mapping techniques. They determined that boundaries associated with regions where atoms are closely packed together most readily resist cracking. This analysis revealed that when a crack encounters such a boundary, it’s deflected to a less direct path and crack growth is slowed.

Newswise: End-run Spreads Lithium Throughout Battery Electrodes
Released: 28-Aug-2019 1:05 PM EDT
End-run Spreads Lithium Throughout Battery Electrodes
Department of Energy, Office of Science

Scientists used chemically sensitive X-ray microscopy to map lithium transport during battery operation.

Newswise: Knowledgebase Is Power for Nuclear Reactor Developers
Released: 27-Aug-2019 10:05 AM EDT
Knowledgebase Is Power for Nuclear Reactor Developers
Oak Ridge National Laboratory

Six new nuclear reactor technologies are planned to commercially deploy between 2030 and 2040. ORNL’s Weiju Ren heads a project managing structural materials information. This conversation explores challenges and opportunities in sharing nuclear materials knowledge internationally.

Newswise: Excited Atoms Rush Independently to New Positions
Released: 26-Aug-2019 1:05 PM EDT
Excited Atoms Rush Independently to New Positions
Department of Energy, Office of Science

How atoms react to a sudden burst of light shows scientists how the larger material might act in sensors, data storage devices, and more.

Newswise: Chaos Ensues When Lasers and Plasma Meet
Released: 23-Aug-2019 1:05 PM EDT
Chaos Ensues When Lasers and Plasma Meet
Department of Energy, Office of Science

Warp+PXR dramatically improves the accuracy of the simulations compared to those typically used in plasma research. Now, researchers can simulate lasers’ interactions with plasma with much higher precision.

Newswise: This Superconductor Does Not Take Light Lightly
Released: 22-Aug-2019 1:05 PM EDT
This Superconductor Does Not Take Light Lightly
Department of Energy, Office of Science

Superconductors are materials that show no resistance to electrical current when cooled. Recently, scientists discovered a new superconducting material. Now, scientists have found that when exposed to low-energy ultraviolet light, the material acts as a superconductor at higher temperatures.
