N.E. Chemcat Corporation has licensed electrocatalysts developed by scientists at Brookhaven National Laboratory that can reduce the use of costly platinum and increase the effectiveness of fuel cells for use in electric vehicles. In addition, the license includes innovative methods for making the catalysts and an apparatus design used in manufacturing them.
Two experiments at the Large Hadron Collider have nearly eliminated the space in which the Higgs boson could dwell, scientists announced Tuesday. However, the ATLAS and CMS experiments see modest excesses in their data that could soon uncover the famous missing piece of the physics puzzle.
Researchers at Brookhaven National Laboratory and in Ecuador have found that, at just the right temperatures, nanoclusters form and improve the flow of electrical current through certain oxide materials. This work could be used in a number of industrial applications including spintronics, which exploit electrical and magnetic properties for use in solid-state electronics.
When a skier rushes down a ski slope or a skater glides across an ice rink, a very thin melted layer of liquid water forms on the surface of the ice crystals, which allows for a smooth glide instead of a rough skid. In a recent experiment, scientists have discovered that the interface between the surface and bulk electronic structures of certain crystalline materials can act in much the same way.
In terms of emissions, just one pound of sulfur hexafluoride, a nontoxic gas used in electric insulation, is equivalent to about 11 tons of carbon dioxide. Energy Department experts are hunting down this and other fugitive carbon emissions and have already prevented the release of 600,000 metric tons of carbon equivalent.
Increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in dry regions or seasons, while increasing rain, snowfall, and the intensity of severe storms in wet regions or seasons, says a new study by a University of Maryland-led team of researchers.
Not all quantum dots are created equal, however—some, called simply "bad" quantum dots, blink in an irregular, unreliable way. This unreliability makes them problematic to work with. Researchers at Brookhaven National Laboratory's Center for Functional Nanomaterials have just figured out why bad dots are so unreliable.
After years of forefront calculations that shed light on much breakthrough physics at the Relativistic Heavy Ion Collider and other vital physics, the retired giant supercomputer QCDOC, for quantum chromodynamics (QCD) on a chip, regenerates in the newest, more powerful pioneering supercomputer, QCDCQ (QCD with chiral quarks).
Among the complex molecular processes involved in the development of bacteria-borne disease is quorum sensing, the way bacteria communicate and coordinate collective behaviors. By studying how to inhibit quorum sensing, scientists may be able create antibacterial pharmaceuticals for a variety of ailments.
Heavy-ion fusion, a special approach to creating fusion for electrical power production, has long been the choice of Lawrence Berkeley National Laboratory accelerator physicists. Now the near prospect of "burn and gain" at the National Ignition Facility, plus a forthcoming National Academies report on inertial confinement fusion energy, have spurred new interest in heavy-ion fusion.
Brookhaven National Laboratory scientists reveal how substituting just a few atoms can cause widespread disruption of the delicate electron interactions that give a particular "heavy fermion" material its unique properties, including superconductivity.
A team of Brookhaven National Laboratory researchers has fabricated a transparent chemical reactor vessel that may give scientists in many fields a window into real-time chemistry. Scientists in the Lab's Energy Storage Group recently used the transparent reactor to study the synthesis of lithium iron phosphate for rechargeable batteries.
By studying three layers of graphene stacked in a particular way, scientists at Brookhaven National Laboratory have discovered a “little universe” populated by a new kind of “quasiparticles”—particle-like excitations of electric charge. Unlike massless photon-like quasiparticles in single-layer graphene, these new quasiparticles have mass, which depends on their energy, and would become infinitely massive at rest.
Scientists at Brookhaven National Laboratory and collaborators at the Karolinska Institute in Sweden have discovered how an enzyme "knows" where to insert a double bond when desaturating plant fatty acids. Understanding the mechanism—which relies on a single amino acid far from the enzyme's active site—solves a 40-year mystery of how these enzymes exert such location-specific control.
As scientists attempt to improve the performance of organic photovoltaic devices they’ve discovered that how the molecules stack up can make a big difference. Scientists at Brookhaven National Laboratory have shown nanoimprinting imparts a sense of order among the polymer chains, orienting them in a preferred configuration that should improve solar cell performance.
Scientists working at the National Synchrotron Light Source have discovered an unusually fragile, unstable magnetic state in a member of a class of materials known for its robust magnetic behaviors. Their discovery could lead to applications in the emerging field of spintronics.
On Monday, scientists collaborating on the ATLAS and CMS experiments at CERN’s Large Hadron Collider said their research excluded with 95% certainty the existence of a Higgs boson over most of the mass region from 145 to 466 GeV. This significantly narrows the mass region in which the Higgs boson could be hiding.
The Daya Bay Reactor Neutrino Experiment has begun its quest to answer some of the most puzzling questions about the elusive elementary particles known as neutrinos. The experiment's first completed set of twin detectors is now recording interactions of antineutrinos as they travel away from the powerful reactors of the China Guangdong Nuclear Power Group in southern China.
Brookhaven National Laboratory and Nanofactory Instruments AB have solved the major engineering challenge necessary to integrate optoelectronic and imaging capabilities within the confined space of a high-resolution TEM, adding a variety of new capabilities.
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a computational model for analyzing the metabolic processes in rapeseed plants—particularly those related to the production of oils in their seeds. Their goal is to find ways to optimize the production of plant oils that have widespread potential as renewable resources for fuel and industrial chemicals.
Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have observed a new way that magnetic and electric properties can coexist in a special class of metals. These materials, known as multiferroics, could serve as the basis for the next generation of faster and energy-efficient logic, memory, and sensing technology.
A team of scientists studying the parent compound of a cuprate (copper-oxide) superconductor has discovered a link between two different states, or phases, of that matter—and written a mathematical theory to describe the relationship. This work is expected to help scientists predict the material's behavior under varying conditions, and may help explain how it’s transformed into a superconductor able to carry current with no energy loss.
A multi-institutional team has been awarded government funding to create out of many separate streams of biological information a single, integrated cyber-"knowledgebase" (called Kbase) focused specifically on two fundamentally important forms of life.
Researchers at Columbia University’s Engineering School have built optical nanostructures that enable them to slow photons down and fully control light dispersion. They have shown that it is possible for light (electromagnetic waves) to propagate from point A to point B without accumulating any phase, spreading through the artificial medium as if the medium is completely missing in space.
Brookhaven National Laboratory researchers are using high-frequency sound waves in conjunction with extremely bright X-rays to get a look at the atomic structures of the complex biological molecules that make our bodies work.
