Superconductivity and Charge Density Waves Caught Intertwining at the Nanoscale
SLAC National Accelerator Laboratory

Scientists discover superconductivity and charge density waves are intrinsically interconnected at the nanoscopic level, a new understanding that could help lead to the next generation of electronics and computers.

Newswise: Oxygen Formation in the Light of Gamma Beams

Oxygen Formation in the Light of Gamma Beams
Department of Energy, Office of Science

Nuclear fusion reactions in stars consume carbon-12 to produce oxygen-16, and the resulting ratio of carbon to oxygen shapes a star’s evolution. Physicists have not been able to measure this ratio with precision using existing experimental methods. A new method shines gamma beams on an oxygen-16 target and captures images of the outgoing reaction products to obtain higher-quality data on this reaction.

Always adapting: Scientists use Argonne’s Advanced Photon Source to fight SARS-CoV-2 variants
Argonne National Laboratory

Knowing variants of concern can spike rates of illness and death around the globe, scientists using the APS are concentrating efforts on mutations of the virus that causes COVID-19.

Newswise: For Plasma with a Hot Core and Cool Edges, Super-H Mode Shows Promise

For Plasma with a Hot Core and Cool Edges, Super-H Mode Shows Promise
Department of Energy, Office of Science

Fusion reactors face a challenge called “core-edge integration,” which involves maintaining a plasma that is hot at the core but not too hot to damage reactor walls. New research finds that a previously identified operating regime called Super H-mode can leverage the use of impurities such as nitrogen to address this challenge. The research also indicates that Super-H mode can be scaled up to future fusion plants.

Scientists Nail Down 'Destination' for Protein That Delivers Zinc
Brookhaven National Laboratory

New research describes a “chaperone” protein that delivers zinc, a trace element essential for survival in all living things, to where it’s needed. The chaperone could be especially important when access to zinc is limited—for example in nutrient deficient diets and for growing crops on depleted soils.

New Silicon Nanowires Can Really Take the Heat
Lawrence Berkeley National Laboratory

A Berkeley Lab-led research team has demonstrated an ultrathin silicon nanowire that conducts heat 150% more efficiently than conventional materials used in advanced chip technologies. The device could enable smaller, faster, energy-efficient microelectronics.

Newswise: Researchers Stick Out Their Necks to Understand How Fusion Plasmas Fuel Up

Researchers Stick Out Their Necks to Understand How Fusion Plasmas Fuel Up
Department of Energy, Office of Science

The nuclei that smash together to produce fusion energy in a reactor originate from ionized neutral particles. The edges of fusion devices have large numbers of neutrals available to gain or lose electrons to become ions. These neutrals influence several important features of the plasma, including the rate at which the plasma fuels a reactor. A new pinhole camera system called Lyman-alpha Measurement Apparatus (LLAMA) on the DIII-D tokamak helped researchers better understand these neutrals.

Newswise: Artificial Intelligence Agents Argue to Enhance the Speed of Materials Discovery

Artificial Intelligence Agents Argue to Enhance the Speed of Materials Discovery
Department of Energy, Office of Science

Researchers have developed a new artificial intelligence (AI)-powered approach to analyzing X-ray diffraction (XRD) data. The X-ray Crystallography companion Agent (XCA) approach assembles a group of AIs that debate each other while analyzing live streaming X-ray data. Once the AIs cast their final votes, the XCA approach uses the vote tally to interpret what the most likely atomic structure is and to suggest how confident the researchers should be of the AI analysis. The AI analysis matches human effectiveness but takes just seconds.
