Scientists make first detailed measurements of key factors related to high-temperature superconductivity
In independent studies reported in Science and Nature, scientists from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University report two important advances: They measured collective vibrations of electrons for the first time and showed how collective interactions of the electrons with other factors appear to boost superconductivity.
In an effort to improve American competitiveness in high-intensity laser research, the Department of Energy has established LaserNetUS, a $6.8 million initiative that involves the University of Michigan--one of the field's pioneers.
Moss evolved after algae but before vascular land plants, such as ferns and trees, making them an interesting target for scientists studying photosynthesis, the process by which plants convert sunlight to fuel. Now researchers at the Department of Energy's Lawrence Berkeley National Laboratory have made a discovery that could shed light on how plants evolved to move from the ocean to land.
Manganese could advance one of the most promising sources of renewable energy: hydrogen fuel cells. In a study published today (Oct. 29, 2018) in Nature Catalysis, a University at Buffalo-led research team reports on catalysts made from the widely available and inexpensive metal. The advancement could eventually help solve hydrogen fuel cells' most frustrating problem: namely, they're not affordable because most catalysts are made with platinum, which is both rare and expensive.
Either exorbitantly expensive fuel or insanely hot temperatures have made fuel cells a boutique proposition, but now there's one that runs on cheap methane and at much lower temperatures. This is a practical, affordable fuel cell and a "sensation in our world," the engineers say.
Researchers at Lawrence Berkeley National Laboratory and the Joint Center for Artificial Photosynthesis have developed an artificial photosynthesis device called a "hybrid photoelectrochemical and voltaic cell" that turns sunlight and water into two types of energy - hydrogen fuel and electricity.
Climate scientists have not been properly accounting for what plants do at night, and that, it turns out, is a mistake. A new study from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has found that plant nutrient uptake in the absence of photosynthesis affects greenhouse gas emissions to the atmosphere.
New driverless car technologies developed at a University of Delaware lab could lead to a world without traffic lights and speeding tickets. Researchers hope the innovations will bring about the development of driverless cars that use 19 to 22 percent less fuel.
A novel new way to keep oil from clogging filters and equipment
Researchers at Washington University in St. Louis take a closer look at lithium metal plating and make some surprising findings that might lead to the next generation of batteries.
Fuel cell efficiency of hydrogen fuel cells decreases as the Nafion membrane, used to separate the anode and cathode within a fuel cell, swells as it interacts with water. Russian and Australian researchers have now shown that this Nafion separator membrane partially unwinds some of its constituent fibers, which then protrude away from the surface into the bulk water phase for hundreds of microns. Their results were published in this week's Journal of Chemical Physics.
Oak Ridge National Laboratory scientists used neutrons, isotopes and simulations to "see" the atomic structure of a saturated solution and found evidence supporting one of two competing hypotheses about how ions come together to form minerals.
Researchers have developed a new class of molecular layer deposition chemistry that paves the way for a new photoactivated molecular layer deposition technique. They report that their new method will expand the tool kit for forming covalently bound organic multilayers at surfaces. These emerging deposition techniques have enabled engineers to produce organic thin films with improved conformality. Richard Closser, Stanford University, will present the findings at the AVS 65th International Symposium and Exhibition, Oct. 21-26, 2018.
Aspergillus fungi play roles in fields including bioenergy, health, and biotechnology. In Nature Genetics, a team led by scientists at the Technical University of Denmark, the DOE Joint Genome Institute, and the Joint Bioenergy Institute, present the first large analysis of an Aspergillus fungal subgroup, section Nigri.
Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the Massachusetts Institute of Technology have demonstrated a surprisingly simple way of flipping a material from one state into another, and then back again, with single flashes of laser light.
Two researchers with personal experience of hurricanes set out to investigate the role of an underestimated factor in storm's strength - salinity. They found that salinity plays a larger role than anyone thought, including them.
Feature describes unexpected discovery of a role the process that seeds magnetic fields plays in mediating a phenomenon that occurs throughout the universe and can disrupt cell phone service and knock out power grids on Earth.
Scientists studying a valuable, but vulnerable, species of poplar have identified the genetic mechanism responsible for the species' inability to resist a pervasive and deadly disease. Their finding could lead to more successful hybrid poplar varieties for increased biofuels and forestry production and protect native trees against infection.
Ames Laboratory has developed a method to measure magnetic properties of superconducting and magnetic materials that exhibit unusual quantum behavior at very low temperatures in high magnetic fields.
Argonne scientists have identified a new class of topological materials made by inserting transition metal atoms into the atomic lattice of a well-known two-dimensional material.
New research reveals an unexpected benefit of large-scale offshore wind farms: the ability to lessen precipitation from hurricanes.
PPPL scientists have found evidence suggesting that a process could remove the unwanted ash produced during fusion reactions and make the fusion processes more efficient within a type of fusion facility known as a field-reversed configuration device.
A new study shows how animals use their tails to keep mosquitoes at bay by combining a swish that blows away most of the biting bugs and a swat that kills the ones that get through.
Scientists, including researchers from the Department of Energy's SLAC National Accelerator Laboratory, have compiled the most detailed catalog of such blobs using eight years of data collected with the Large Area Telescope (LAT) on NASA's Fermi Gamma-Ray Space Telescope. The blobs, including 19 gamma-ray sources that weren't known to be extended before, provide crucial information on how stars are born, how they die, and how galaxies spew out matter trillions of miles into space.
Applying Auto Industry's Fuel-Efficiency Standards to Agriculture Could Net Billions in Corn Sector, Researchers Conclude
Adopting benchmarks similar to the fuel-efficiency standards used by the auto industry in the production of fertilizer could yield $5-8 billion in economic benefits for the U.S. corn sector alone, researchers have concluded in a new analysis.
