Researchers at Berkeley Lab have developed a graphene device that switches from a superconducting material that conducts electricity without losing any energy, to an insulator that resists the flow of electric current - all with a simple flip of a switch.
After blasting a molecule with light, researchers watch its structure vibrate and change in real time
A new study describes how a team of researchers watched a molecule vibrate after they excited it with ultraviolet light.
Now, a team of scientists has completed research into waves that travel through the magnetosphere, deepening understanding of the region and its interaction with our own planet, and opening up new ways to study other planets across the galaxy.
Light dark matter is a thousand times less likely to bump into regular matter than previous astrophysical analyses allowed
A team led by scientists from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University has narrowed down how strongly dark matter particles might interact with normal matter. Based on the number and distribution of small satellite galaxies seen orbiting our Milky Way, the team found this interaction to be at least a thousand times weaker than the strongest interaction allowed by previous astrophysical analyses.
An optical sensor developed at Berkeley Lab could speed up the time it takes to evaluate whether buildings are safe to occupy after a major earthquake. After four years of extensive peer-reviewed research and simulative testing at the University of Nevada's Earthquake Engineering Laboratory, the Discrete Diode Position Sensor (DDPS) will be deployed for the first time this summer in a multi-story building at Berkeley Lab - which sits adjacent to the Hayward Fault, considered one of the most dangerous faults in the United States.
Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory and Los Alamos National Laboratory, along with researchers at Clemson University and Fujitsu Laboratories of America, have developed hybrid algorithms to run on size-limited quantum machines and have demonstrated them for practical applications.
This research is a fundamental discovery of how to engineer proteins onto non-biological surfaces. Artificial proteins engineered from scratch have been assembled into nanorod arrays, designer filaments and honeycomb lattices on the surface of mica, demonstrating control over the way proteins interact with surfaces to form complex structures previously seen only in natural protein systems. The study provides a foundation for understanding how protein-crystal interactions can be systematically programmed and sets the stage for designing novel protein-inorganic hybrid materials.
Argonne National Laboratory played a critical role in the discovery of a DNA-like twisted crystal structure created with a germanium sulfide nanowire, also known as a "van der Waals material." Researchers can tailor these nanowires in many different ways -- twist periods from two to twenty micrometers, lengths up to hundreds of micrometers, and radial dimensions from several hundred nanometers to about ten micrometers. By this means, they can adjust the electrical and optical properties to optimize performance for different applications.
Nearly ten years ago, a group of Israeli clinical researchers emailed Berkeley Lab geneticist Len Pennacchio to ask for his team's help in solving the mystery of a rare inherited disease that caused extreme, and sometimes fatal, chronic diarrhea in children.
Feature reports discovery of an alternative method for measuring the stability of fusion plasma, a critical task for researchers seeking to bring the fusion that powers the sun to Earth.
A Berkeley Lab study modeled different types and ages of homes, retail stores, and office buildings and found that sunlight-reflecting "cool" exterior walls can save as much or more energy than sunlight-reflecting cool roofs in many places across the U.S.
The males of one species of butterfly are more attracted to females that are active, not necessarily what they look like, according to a recent research conducted at Augustana University.The paper, "Behaviour before beauty: Signal weighting during mate selection in the butterfly Papilio polytes," found that males of the species noticed the activity levels of potential female mates, not their markings.
Newly published research from a team of scientists led by the U.S. Department of Energy's Ames Laboratory sheds more light on the nature of high-temperature iron-based superconductivity.
A chemical surface treatment boosts the catalytic activity of the wire-looking nanostructures for a key reaction in solar fuel production.
Researchers at Lawrence Berkeley National Laboratory have shown that an algorithm with no training in materials science can scan the text of millions of papers and uncover new scientific knowledge. They collected 3.3 million abstracts of published materials science papers and fed them into an algorithm called Word2vec. By analyzing relationships between words the algorithm was able to predict discoveries of new thermoelectric materials years in advance and suggest as-yet unknown materials as candidates for thermoelectric materials.
If you chart the stability of atomic cores (nuclei), the trend is that adding more protons and neutrons makes the atom less stable. However, there's an island of stability that bucks this trend. If scientists can provide an easier way of producing elements predicted to be on that island of stability, they can fine-tune today's nuclear models. Such elements were difficult to produce, until a team built an apparatus that efficiently produces superheavy elements by transferring multiple nucleons (either protons or neutrons).
Physicists from PPPL and General Atomics have concluded that injecting tiny beryllium pellets into ITER could help stabilize the plasma that fuels fusion reactions.
Scientists have identified highly active yet stable catalysts for use in fuel cells that contain only a quarter of the platinum as compared to existing devices. Platinum is essential for promoting reactions in these fuel cells. However, the precious metal is rare and expensive. Interactions between platinum-cobalt particles and a precious metal-free support contribute to the improved performance.
Researchers from the University of Vermont, Boston University, and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have demonstrated a new experimental capability for watching thin film growth in real-time. Using the National Synchrotron Light Source II (NSLS-II)--a DOE Office of Science User Facility at Brookhaven--the researchers were able to produce a "movie" of thin film growth that depicts the process more accurately than traditional techniques can.

For decades, scientists have been intrigued by a class of electronic materials called relaxor ferroelectrics. These lead-based materials can convert mechanical energy to electrical energy and vice versa. The underlying mechanism for this behavior has been elusive. The challenge was getting a detailed view of the atomic structure, critical to resolve the debate concerning the role of local order. Now, novel neutron-based tools and methods have resolved this debate--revealing the relationship of local order motifs and how they affect the underlying properties.
Discovery of novel polymers with extreme stretching, vibration suppression, and self-healing.
Scientists at Harvard have developed a superconductor that is only one nanometer thick. By studying fluctuations in this ultra-thin material as it transitions into superconductivity, the scientists gained insight into the processes that drive superconductivity. They used the new technology to confirm a 23-year-old theory of superconductors developed by scientist Valerii Vinokur from the U.S. Department of Energy's (DOE) Argonne National Laboratory. Their work could have applications in virtually any technology that uses electricity.
To create materials that handle heat well, scientists are exploring how vibrations within the atomic structure carry heat. Atomic vibrations used to remove heat usually are limited by the speed of sound. A new observation may have shattered that limit. A team of scientists observed particles, called phasons, moving faster than the speed of sound that carry heat. The phasons use a pattern of motion in which atoms rearrange themselves, allowing heat to move faster.
