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...

Scientists find new way to produce safer lithium-ion batteries

For the first time, researchers who explore the physical and chemical properties of electrical energy storage have found a new way to improve lithium-ion...

Flat-panel tech could transform antennas, wireless and phone communications

What goes in is not what comes out with a spatio-temporally modulated metasurface reflector. Researchers are reinventing the mirror, at least for microwaves, potentially replacing...

New material design has put artificial photosynthesis within reach

Scientist Heinz Frei has spent decades working toward building an artificial version of one of nature's most elegant and effective machines: The leaf. Researchers around the...

Scientists develop a safer, more durable lithium ion battery

The popular myth that a spider is never more than a few feet away is arguably more true of lithium-ion batteries than of arachnids. Powering...

New way to keep lithium metal batteries from catching fire

Nanoengineers at the University of California San Diego developed a safety feature that prevents lithium metal batteries from rapidly heating up and catching fire...

Fast-charging could damage electric car batteries

Just 25 industry-standard fast charging cycles can ruin a car’s batteries. Commercial fast-charging stations subject electric car batteries to high temperatures and high resistance that...

New electric car battery could last for 1 million miles

A new lithium-ion battery for electric cars is safe, has high power, and can last for a million miles. Electric car batteries typically require a...

World’s smelliest fruit could charge your smartphone

Imagine if we could use naturally-grown products, like plants and fruit, to store electricity that charges commonly used electronics like smartphones, tablets, laptops or...

Layered solar cells gain highest power-conversion efficiencies to date

The future's getting brighter for solar power. Researchers from CU Boulder have created a low-cost solar cell with one of the highest power-conversion efficiencies to...
