Scientists have designed a conceptual spacecraft to deflect Earth-bound asteroids and evaluated whether it would be able to nudge a massive asteroid – which has a remote chance to hitting Earth in 2135 – off course.
Late last year, Sandia researchers completed an eight-month, 14,500-mile triathlon-like test to gather data on the bumps and jolts spent nuclear fuel experiences during transportation.
Physicists at PPPL have recently found that drifting particles in plasma can forestall instabilities that reduce the pressure crucial to high-performance fusion reactions inside these facilities.
Tracking atoms is crucial to improving the efficiency of next-generation perovskite solar cells.
Physicians have long used CT scans to get 3D imagery of the inner workings of the human body. Now, physicists are working toward getting their first CT scans of the inner workings of the nucleus. A measurement of quarks in helium nuclei published last fall in Physical Review Letters demonstrates that 3D imaging of the inner structure of the nucleus is now possible.
The CUORE experiment set the tightest limits yet on the rare decay of tellurium-130, providing insights into the nature of neutrinos.
The observation of an abnormal state of matter in a 2-D magnetic material is the latest development in the race to harness novel electronic properties for more robust and efficient next-generation devices. Neutron scattering at Oak Ridge National Laboratory helped researchers investigate a graphene-like strontium-manganese-antimony material that hosts what they suspect is a Weyl semimetal phase.
Researchers at the DIII-D National Fusion Facility used a “reduced physics” fluid model of plasma turbulence to explain unexpected properties of the density profile inside a tokamak experiment. Modeling plasma’s turbulent behavior could help scientists optimize the tokamak performance in future fusion reactors like ITER. They discuss their findings in this week’s Physics of Plasmas.
Article describes dissertation award for graduate of Princeton University Department of Astrophysical Sciences.
PPPL physicist Francesca Poli and coauthors recently published findings that describe an approach that for the first time simultaneously simulates the plasma, the magnetic islands, and the feedback control from waves that provide so-called electron cyclotron heating and current drive.
For the first time, scientists demonstrated a long-theorized nuclear effect called nuclear excitation by electron capture. This advance tests theoretical models that describe how nuclear and atomic realms interact and may also provide new insights into how star elements are created.
UPTON, NY — Elke-Caroline Aschenauer, a senior physicist at the U.S. Department of Energy's Brookhaven National Laboratory, has been awarded a Humboldt Research Award for her contributions to the field of experimental nuclear physics. This prestigious international award—issued by the Alexander von Humboldt Foundation in Bonn, Germany—comes with a prize of €60,000 (more than $70,000 U.
Berkeley Lab physicists and their collaborators have demonstrated that computers are ready to tackle the universe’s greatest mysteries – they used neural networks to perform a deep dive into data simulating the subatomic particle soup that may have existed just microseconds after the big bang.
The U.S. Department of Energy honors Argonne researchers in top 40 research-paper countdown.
Scientists map electrical currents emanating from the boundary of a tokamak plasma, providing new information for reactor design.
International collaborators advance physics basis for tokamak plasma confinement at low rotation, potentially benefiting a fusion reactor.
Large-scale simulations of quarks promise precise view of reactions of astrophysical importance.
Gravitational wave observations combined with optical and gamma-ray data confirm earlier predictions, offer insights into how the galaxy produces lead, mercury, and other elements.
Article describes development of deep learning neural network to predict disruptions of fusion plasma.
Researchers from Stanford University, two Department of Energy national labs and the battery manufacturer Samsung created a comprehensive picture of how the same chemical processes that give cathodes their high capacity are also linked to changes in atomic structure that sap performance.
