The century-old challenge of storing and transporting acetylene safely may have been solved in principle by a team of scientists working at NIST.
Engineers at Ohio State University have found a way to double the production of the biofuel butanol, which might someday replace gasoline in automobiles.
Renewable Energies Will Benefit US Workers; Shifting to Wind & Solar Could Eliminate 130 Deaths Annually
Expansion of renewable energies should appreciably improve the health status of the 700,000 US workers employed in the energy sector, according to a commentary by Medical College of Wisconsin researchers, in Milwaukee. Their review is published in the August 19, 2009, issue of JAMA.
NIST and the American National Standards Institute (ANSI) have published a report on the inaugural meeting of the Nuclear Energy Standards Coordination Collaborative (NESCC), a new ANSI Standards Panel, co-chaired by NIST and ANSI, to address the current and future standards needs of the nuclear energy industry.
A highly efficient system for generating and distributing energy is lean, mean and green "" and could be as close as the nearest farm, according to a University of Connecticut professor.
University of Washington researchers have found a way to measure exactly how much electrical current is carried by tiny bubbles and channels that form inside nanoscale solar cells, paving the way for development of more efficient materials.
Diesel and gasoline fuel sources both bring unique assets and liabilities to powering internal combustion engines. But what if an engine could be programmed to harvest the best properties of both fuel sources at once, on the fly, by blending the fuels within the combustion chamber?
For the first time in the history of scientific ocean drilling, researchers aboard the riser-equipped drilling vessel CHIKYU successfully drilled down to a depth of 1,603.7 meters beneath the sea floor into an earthquake-generating zone off the coast of Japan.
A new class of economically viable solar power cells""cheap, flexible and easy to make""has come a step closer to reality as a result of recent work at the National Institute of Standards and Technology (NIST), where scientists have deepened their understanding of the complex organic films at the heart of the devices.
Burning coal and biomass to generate power while reducing emissions at the same time, Circulating Fluidized Bed (CFB) technology uses fluidization to mix and circulate fuel particles with limestone as they burn in a low-temperature combustion process. Unlike conventional steam generators that burn the fuel in a massive high-temperature flame, CFB technology does not have burners or a flame within its furnace.
It's called a Plug-in Hybrid Retrofit Kit. It could double the average mileage per gallon. If 50 percent of the automobiles in America used it, it could save 120 million gallons of fuel per day""globally, as much as 600 million gallons per day. It will reduce our dependence on oil. It will reduce carbon emissions and could create 2,000 new manufacturing jobs. A potential foreign market is growing daily.
A group of Virginia Tech students have produced more than 200 gallons of biodiesel as part of a senior design project. They are using it in two pickup trucks.
Solid oxide fuel cells (SOFCs) have great potential for stationary and mobile applications. But SOFCs have had a flaw "" the integrity of the seals within and between power-producing units. A materials science professor has invented a self-healing seal that will provide strength and long-term stability.
Acquiring cheap genome sequence data can improve the quality of feedstocks used to create biofuels, according to a new study published in The Plant Genome.
Trees positioned to shade the west and south sides of a house may decrease summertime electric bills by 5 percent on average, according to a recent study of California homes by researchers from NIST and the U.S. Department of Agriculture.
PNNL's Smart Charger Controller simplifies electric vehicle recharging, protects the grid and saves consumers money; device automatically activates the vehicle's battery to recharge at times of least stress on the grid.
Federal requirements to increase the production of ethanol has developed into a "drink-or-drive issue" in the Midwest as a result of biofuel production's impact on water supplies and water quality, says an environmental engineering researcher at Missouri University of Science and Technology in the latest issue of the journal Environmental Science & Technology.
A research team from Northeastern University and NIST has discovered, serendipitously, that a residue of a process used to build arrays of titania nanotubes--a residue that wasn't even noticed before this--plays an important role in improving the performance of the nanotubes in solar cells that produce hydrogen gas from water.
Roughly 20 percent of the electricity consumed worldwide is used to light homes, businesses, and other private and public spaces. Though this consumption represents a large drain on resources, it also presents a tremendous opportunity for savings. Improving the efficiency of commercially available light bulbs -- even a little -- could translate into dramatically lower energy usage if implemented widely.
Weizmann Institute scientists have identified a new mode of bond generation between oxygen atoms. This work is a step toward development of an efficient artificial catalyst for solar-driven splitting of water into oxygen and hydrogen, which is a major goal of renewable, clean energy research.
Chemists are reporting development of what they termed the first economical, eco-friendly process to convert algae oil into biodiesel fuel "" a discovery they predict could one day lead to U.S. independence from petroleum as a fuel. The study is scheduled for presentation in March at the 237th National Meeting of the American Chemical Society.
