Scientists develop high-performance lithium-sulfur batteries
Scientists have developed Fe1-xS-decorated mesoporous carbon spheres as the nanoreactor, which can be applied as lithium-sulfur battery cathode. The nanoreactor showed excellent polysulfide catalytic activity...
New scavenger technology allows robots to ‘eat’ metal for energy
When electronics need their own power sources, there are two basic options: batteries and harvesters. Batteries store energy internally, but are therefore heavy and have...
Six-junction solar cell sets two world records for efficiency
Scientists at the National Renewable Energy Laboratory (NREL) have fabricated a solar cell with an efficiency of nearly 50%. The six-junction solar cell now holds...
Scientists develop a better redox flow battery
USC scientists have developed a new battery that could solve the electricity storage problem constraining widespread use of renewable energy. The technology is a new...
Scientists predict new state of matter
Three scientists from the University of Chicago have run the numbers, and they believe there may be a way to make a material that...
New AI technique could check battery health with 10x higher accuracy
Researchers have designed a machine learning method that can predict battery health with 10x higher accuracy than current industry standard. The new method could aid...
‘Zoombombers’ want to troll your online meetings. Here’s how to stop them
Zoombombing” in case you haven’t heard, is the unsavoury practice of posting distressing comments, pictures or videos after gatecrashing virtual meetings hosted by the...
Scientists tap unused energy source to power future smart sensor networks
The electricity that lights our homes and powers our appliances also creates small magnetic fields that are present all around us. Scientists have developed a...
On Mars or Earth, biohybrid can turn CO2 into new products
If humans ever hope to colonize Mars, the settlers will need to manufacture on-planet a huge range of organic compounds, from fuels to drugs,...
Double-walled nanotubes could be highly useful for solar panels, says new study
One nanotube could be great for electronics applications, but there's new evidence that two could be tops. Rice University engineers already knew that size matters...
