Power-free system harnesses evaporation to keep items cool
Nov 12, 2020 (SPX)
Most people wouldn't think of wearing a camel-hair coat on a hot summer's day, but in fact many desert-dwelling people do tend to wear heavy outer garments, for...
Improving high-energy lithium-ion batteries with carbon filler
Nov 11, 2020 (SPX)
The optimum battery design involves thick electrode structures. This enhances the energy density, but the design suffers from poor lithium-ion transport, a key ...
New kind of superconductivity discovered
Nov 09, 2020 (SPX)
If you're like most people, there are three states of matter in your everyday life: solid, liquid and gas. You might be familiar with a fourth state of matter c...
Pushing the envelope with fusion magnets
Nov 09, 2020 (SPX)
David Fischer remembers growing up in Vienna, Austria, imagining how best to cool the furnace used to contain the hot soup of ions known as plasma in a fusion d...
Boosting the capacity of supercapacitors
Nov 03, 2020 (SPX)
Supercapacitors use technology that is significantly different from the reversible chemical reactions used in rechargeable batteries. They store electrical ener...
Predictive model reveals function of promising energy harvester device
Nov 02, 2020 (SPX)
In research recently published online in the Journal of Micromechanics and Microengineering, engineers at Rensselaer Polytechnic Institute developed a predictiv...
Infrared light antenna powers molecular motor
Oct 29, 2020 (SPX)
For biological applications, this requires the motors to be driven by low-energy, low-intensity light that penetrates tissue. Chemists at the University of Gron...
Realistic simulation of plasma edge instabilities in tokamaks
Oct 23, 2020 (SPX)
Typically, one tenth of the total energy content can thus be ejected abruptly. While the present generation of medium-sized fusion devices can cope with this, l...
Highview Power and Enlasa to develop giga-scale cryogenic energy storage projects in Latin America
Oct 23, 2020 (SPX)
"We are excited to work with Enlasa to bring Highview's technology to Chile," said Javier Cavada, CEO and President of Highview Power. "Together, our two compan...
Good vibrations for new energy
Oct 22, 2020 (SPX)
Australian researchers led by Flinders University are picking up the challenge of 'scavenging' invisible power from low-frequency vibrations in the surrounding ...
LiU researchers first to develop an organic battery
Oct 16, 2020 (SPX)
Redox flow batteries are stationary batteries in which the energy is located in the electrolyte, outside of the cell itself, as in a fuel cell. They are often m...
A new approach boosts lithium-ion battery efficiency and puts out fires, too
Oct 16, 2020 (SPX)
If adopted, the researchers said, this technology could address two major goals of battery research: extending the driving range of electric vehicles and reduci...
How impurities enhance a thermoelectric material at the atomic level
Oct 16, 2020 (SPX)
This phenomenon can be exploited to produce electricity using the enormous amount of waste heat that human activity generates, such as that from automobiles and...
UNLV and University of Rochester physicists observe room-temperature superconductivity
Oct 15, 2020 (SPX)
The research team led by University of Rochester physicist Ranga Dias in collaboration with Ashkan Salamat, assistant professor of physics and astronomy at UNLV...
The perfect angle for e-skin energy storage
Oct 14, 2020 (SPX)
Lee says "Demand for remote diagnosis and wearable devices is rapidly increasing and thus, many scientists are focusing their research efforts on developing var...
Record high values of peak power with picosecond generators
Oct 14, 2020 (SPX)
They also have applications in high-power microwave electronics, but researchers are constantly striving to obtain shorter and more powerful pulses. In Review o...
Superconductor technology for smaller, sooner fusion
Oct 14, 2020 (SPX)
A key technical challenge to realizing this vision, though, has been getting HTS superconductors to work in an integrated way in the development of new, high-pe...
Could megatesla magnetic fields be realized on Earth?
Oct 07, 2020 (SPX)
Geomagnetism is 0.3-0.5 gauss (G) and magnetic tomography (MRI) used in hospitals is about 1 tesla (T = 104 G). By contrast, future magnetic fusion and maglev t...
Energy-harvesting plastics pass the acid test
Oct 07, 2020 (SPX)
When two sides of a semiconductor are at different temperatures, electron migration from hot to cool areas can generate a current. This phenomenon, known as the...
