Getting the biggest bang out of plasma jets
Jun 27, 2017 (SPX)
Capillary discharge plasma jets are those that are created by a large current that passes through a low-density gas in what is called a capillary chamber. The g...
Illuminating a better way to calculate excitation energy
Jun 27, 2017 (SPX)
A glow stick's color offers a direct way to visualize excitation energy, the energy required to send a single electron into an excited state. But this phenomeno...

Rosatom Develops Radiation-Powered Electricity Source for Medicine, Outer Space
Jun 23, 2017 (Sputnik)
Russia's "Luch" enterprise, which is part of the scientific division of Rosatom, has created a small-scale power source based on the radioactive nickel-63 (Ni-6...
Deceleration of runaway electrons paves the way for fusion power
Jun 23, 2017 (SPX)
It takes high pressure and temperatures of about 150 million degrees to get atoms to combine. As if that was not enough, runaway electrons are wreaking havoc in...
New efficient, low-temperature catalyst for hydrogen production
Jun 23, 2017 (SPX)
"This catalyst produces a purer form of hydrogen to feed into the fuel cell," said Jose Rodriguez, a chemist at the U.S. Department of Energy's (DOE) Brookhaven...
Battery improvements spark HEV EV market breakthrough
Jun 20, 2017 (SPX)
"Aside from charging infrastructures, battery cost and life have proved the greatest obstacles to growth in the HEV/EV market so far. It's definitely not the el...
Clean energy stored in electric vehicles to power buildings
Jun 16, 2017 (SPX)
Dr Kotub Uddin, with colleagues from WMG's Energy and Electrical Systems group and Jaguar Land Rover, has demonstrated that vehicle-to-grid (V2G) technology can...
Making hydrogen fuel from humid air
Jun 16, 2017 (SPX)
Traditionally, hydrogen destined for industrial use has come from fossil fuels. But this approach creates carbon byproducts and other pollutants. In search of a...
Zig-zagging device focuses high-energy radiation emissions
Jun 16, 2017 (SPX)
To design devices that steadily emit a specific type of radiation, physicists use a special kind of crystal, referred to as a crystalline undulator. In a recent...
Liquified gas electrolytes power new lower-temperature battery
Jun 16, 2017 (UPI)
The technology could help make lithium ion batteries safer and more efficient, as well as boost the range of electric vehicles during cold winter months. The ne...
A seaweed derivative could be just what lithium-sulfur batteries need
Jun 16, 2017 (SPX)
In research led by Gao Liu, the team unexpectedly found that carrageenan, a seaweed derivative, acts as a stabilizer in lithium-sulfur batteries. Better stabili...
Batteries from scrap metal
Jun 12, 2017 (SPX)
As reported in the journal Angewandte Chemie, the rust is converted directly into a compact layer with a grid structure that can store potassium ions. A coating...

Low cost, scalable water-splitting fuels the future hydrogen economy
Jun 08, 2017 (SPX)
"Energy is the most important issue of our time, and for energy, fuel cells are crucially important, and then for fuel cells, hydrogen is most important," said ...
Scientists propose new method to correct common power problem in microgrids
Jun 08, 2017 (SPX)
Microgrids are island-like pods of power generation with bridges to the main power grid. If power supplied by the main grid stops, the microgrid can disconnect ...
