Scientists seeking to understand the mechanism underlying superconductivity in "stripe-ordered" cuprates--copper-oxide materials with alternating areas of electric charge and magnetism--discovered an unusual metallic state when attempting to turn superconductivity off. They found that under the conditions of their experiment, even after the material loses its ability to carry electrical current with no energy loss, it retains some conductivity--and possibly the electron (or hole) pairs required for its superconducting superpower.
Beam chopper cuts accelerator-generated ion beams under highly demanding conditions.
Successful models of the fraught dynamics of two particle beams in close contact lead to smoother sailing in an area of particle acceleration.
Energy is transferred through the structure in a way that boosts its response to light, showing promise for solar cell applications.
Researchers at Berkeley Lab have developed a pulsed electron beam technique that enables high-resolution imaging of magnesium chloride without damage. This approach could apply to a vast range of beam-sensitive materials, and help to create a path toward sustainable plastics.

Particles act in a way that justifies extrapolating simulation results to astrophysical scales.
PNNL's Dr. Svitlana Volkova and her the team analyzed three years worth of discussions on Reddit from January 2015 to January 2018 measuring the speed and scale of discussion spread related to Bitcoin, Ethereum, and Monero cryptocurrencies.
Theorized dark matter particles haven't yet shown up where scientists had expected them. So Berkeley Lab researchers are now designing new and nimble experiments that can look for dark matter in previously unexplored ranges of particle mass and energy, and using previously untested methods.
Scientists at Brookhaven Lab and the University of Arkansas have developed a highly efficient catalyst for extracting electrical energy from ethanol, an easy-to-store liquid fuel that can be generated from renewable resources. The catalyst steers the electro-oxidation of ethanol down an ideal chemical pathway that releases the liquid fuel's full potential of stored energy.
Release proposes explanation for failure to focus accelerator-fired ion beams.
For years, routine testing has shown that watersheds of the Mahaulepu Valley and Waikomo Stream in southeast Kauai frequently contain high counts of potentially pathogenic fecal indicator bacteria (FIB). To better understand the cause of the high FIB counts, the DOH commissioned a study by Berkeley Lab microbial ecologists Gary Andersen and Eric Dubinsky. After using a powerful microbial detection tool called the PhyloChip, the scientists concluded that most of the past monitoring results were false positives.
A first-of-its-kind computer simulation reveals self-healing cement for geothermal and oil and gas wells performs better than originally thought.
Researchers use advanced nuclear models to explain 50-year mystery surrounding the process stars use to transform elements.
Researchers at Lawrence Berkeley National Laboratory have developed a new chemical separation method that is vastly more efficient than conventional processes, opening the door to faster discovery of new elements, easier nuclear fuel reprocessing, and, most tantalizing, a better way to attain actinium-225, a promising therapeutic isotope for cancer treatment.
A team led by scientists at Oak Ridge National Laboratory explored how atomically thin two-dimensional (2D) crystals can grow over 3D objects and how the curvature of those objects can stretch and strain the crystals.
A multi-institute team of researchers has developed the most comprehensive view yet of how repeated charging damages lithium-ion battery electrodes. Manufacturers could potentially use this information to design more reliable and longer-lasting batteries for smartphones and cars, the researchers say.
ORNL story tips: Tiny test fuels by ORNL explore new reactor fuels more rapidly; ORNL-developed computing method detects, reports bugs in VA's healthcare data system; new heat transport study in thermoelectric materials may lead to better heat-to-electricity conversion.
A team of scientists has for the first time created a particular form of coherent and magnetized plasma jet that could deepen the understanding of the workings of much larger jets that stream from newborn stars and possibly black holes.
Researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed a new, organic cathode material for lithium batteries. With sulfur at its core, the material is more energy-dense, cost-effective, and environmentally friendly than traditional cathode materials in lithium batteries.
In a study that combines groundbreaking experimental work and theoretical calculations, researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory, in collaboration with scientists in Germany and Poland, have determined the nuclear geometry of two isotopes of boron. The result could help open a path to precise calculations of the structure of other nuclei that scientists could experimentally validate.
The radii of three proton-rich calcium isotopes are smaller than previously predicted because models didn't account for two nuclear interactions.
