electricity
Much like humans, materials are capable of some pretty remarkable things when they're placed under pressure. In fact, under the right conditions, materials can even produce electricity.
RIVERSIDE, Calif. -- Graphene is nature's thinnest elastic material and displays exceptional mechanical and electronic properties. Its one-atom thickness, planar geometry, high current-carrying capacity and thermal conductivity make it ideally suited for further miniaturizing electronics through ultra-small devices and components for semiconductor circuits and computers.
Concerns about dwindling fossil fuel resources, current levels of petroleum consumption, and growing pressure to shift to more sustainable energy sources are among the many factors prompting the transition from our current energy infrastructure to one that uses less carbon and requires the efficient conversion of energy.
DOVER, Del. -- Hydrogen fuel-cell vehicles (FCVs) can be an important part of the solution to America's energy crisis, says Dr. Andrew Goudy of Delaware State University. He is leading a research team striving to solve a key technical FCV puzzle.
The air in Beijing during the 2008 Olympics was cleaner than the previous year's, due to aggressive efforts by the Chinese government to curtail traffic, increase emissions standards and halt construction in preparation for the games, according to a Cornell study.
LIVERMORE, Calif. - Americans used more solar, nuclear, biomass and wind energy in 2008 than they did in 2007, according to the most recent energy flow charts released by the Lawrence Livermore National Laboratory. The nation used less coal and petroleum during the same time frame and only slightly increased its natural gas consumption. Geothermal energy use remained the same.
For the fourth consecutive year, the U.S. was home to the fastest-growing wind power market in the world in 2008, according to a report released by the U.S. Department of Energy and prepared by Lawrence Berkeley National Laboratory (Berkeley Lab). Specifically, U.S. wind power capacity additions increased by 60 percent in 2008, representing a $16 billion investment in new wind projects.
RICHLAND, Wash. -- A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating virtually pollution-free electrical energy.
Drugs that block a growth factor receptor on brain cells may prevent epilepsy after brain damage, according to a new study appearing in the July 15 issue of the Journal of Neuroscience.
BEER-SHEVA, ISRAEL JULY, 15 2009 -- Dr. Alon Friedman, a neurosurgeon, professor and researcher at Ben-Gurion University of the Negev, working with researchers from UC Berkeley, California have identified a TGF Beta Blocker that when given to rats prevents epilepsy after brain damage, according to a new study appearing in the July 15 issue of the Journal of Neuroscience.
A team of Yale University researchers has discovered a “repulsive” light force that can be used to manipulate components on silicon microchips, meaning future nanodevices could be controlled by light rather than electricity.
New Haven, Conn. -- A team of Yale University researchers has discovered a "repulsive" light force that can be used to control components on silicon microchips, meaning future nanodevices could be controlled by light rather than electricity.
CORVALLIS, Ore. -- Widely sought efforts to reduce fuels that increase catastrophic fire in Pacific Northwest forests will be counterproductive to another important societal goal of sequestering carbon to help offset global warming, forestry researchers at Oregon State University conclude in a new report.
BERKELEY, CA -- Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have demonstrated a way to fabricate efficient solar cells from low-cost and flexible materials.
Advanced composite materials are playing a vital role in improved design and reduced operating costs for renewable energy technologies. Research presented today [Tuesday 30 June] will highlight how wind, marine and solar power could address these challenges within the renewable energy industry.
