An MIT team has determined formulas to guide development of a promising new high-tech material, composed of insulating metal oxides known as alkaline-earth-metal binary oxides, that could lead to better computer memory chips, refrigeration systems, and other devices.
Researchers have quantified the astonishingly high speeds at which future solar cells would have to operate in order to stretch what are presently seen as natural limits on their energy conversion efficiency.
We must move faster towards a low-carbon world if we are to limit global warming to 2 degrees C this century, experts have warned.
A group of Drexel University researchers have created a fabric-like material electrode that could help make energy storage devices -- batteries and supercapacitors -- faster and less susceptible to leaks or disastrous meltdowns. Their design for a new supercapacitor, which looks something like a furry sponge infused with gelatin, offers a unique alternative to the flammable electrolyte solution that is a common component in these devices.
The UK has low oil and gas resources and limited prospects for fracking, according to a new analysis by scientists at the University of Edinburgh, who recommend a shift towards greater use of renewable, clean energy.
A research lab run by University of Central Florida Professor Yang Yang is developing energy storage technologies that are cheaper, safer and more efficient.
Could the flapping of a butterfly's wings in Costa Rica set off a hurricane in California? For most people, this hypothetical scenario may be difficult to imagine on Earth -- particularly when a real disaster strikes. Yet, in space, similarly small fluctuations in the solar wind as it streams toward the Earth's magnetic shield actually can affect the speed and strength of 'space hurricanes,' researcher Katariina Nykyri of Embry-Riddle Aeronautical University has reported in in the Journal of Geophysical Research - Space Physics.
An enzyme discovered at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) proves adept at breaking down cellulose fibers regardless of whether their crystalline structure is simple or highly complex. No other enzyme has shown that ability.
Next-generation concentrating solar power (CSP) plants require high-temperature fluids, like molten salts, in the range of 550-750 degrees Celsius to store heat and generate electricity. At those high temperatures, however, the molten salts eat away at common alloys used in the heat exchangers, piping, and storage vessels of CSP systems. New research at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) is aimed at mitigating corrosion levels in CSP plants with nickel-based coatings.
Berkeley Lab scientists have developed a new electrocatalyst that can directly convert carbon dioxide into multicarbon fuels and alcohols using record-low inputs of energy. The work is the latest in a round of studies coming out of Berkeley Lab tackling the challenge of a creating a clean chemical manufacturing system that can put carbon dioxide to good use.
