The trees as raw material for elastic high-capacity battery

I never thought that is possible to make elastic high-capacity battery from wood pulp. Now it is obviously.  A very good team of researchers from KTH Royal Swedish Institute of Technology and Stanford University made this come true. They used nanocellulose broken down from tree fibre to produce a kind of elastic foam designed to […]

Bringing down the cost of fuel cells

Engineers at the University of Wisconsin-Milwaukee (UWM) have identified a catalyst that provides the same level of efficiency in microbial fuel cells (MFCs) as the currently used platinum catalyst, but at 5% of the cost.

Self-Assembling Nanocubes

Researchers at the University of California, San Diego Jacobs School of Engineering have developed a technique that enables metallic nanocrystals to self-assemble into larger, complex materials for next-generation antennas and lenses.

Researchers use nanotechnology to harness the power of fireflies

What do fireflies, nanorods, and Christmas lights have in common? Someday, consumers may be able to purchase multicolor strings of light that don’t need electricity or batteries to glow.

ORNL microscopy reveals workings behind promising inexpensive catalyst

A newly developed carbon nanotube material could help lower the cost of fuel cells, catalytic converters and similar energy-related technologies by delivering a substitute for expensive platinum catalysts.

‘Nanocable’ could be big boon for energy storage

Thanks to a little serendipity, researchers at Rice University have created a tiny coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors.

‘Unzipped’ carbon nanotubes could help energize fuel cells and batteries

Multi-walled carbon nanotubes riddled with defects and impurities on the outside could replace some of the expensive platinum catalysts used in fuel cells and metal-air batteries, according to scientists at Stanford University.

Tiny devices that harvest electrical energy from everyday tasks

Imagine charging your phone as you walk, thanks to a paper-thin generator embedded in the sole of your shoe. This futuristic scenario is now a little closer to reality.

Nanocrystal-coated fibers might reduce wasted energy

Researchers are developing a technique that uses nanotechnology to harvest energy from hot pipes or engine components to potentially recover energy wasted in factories, power plants and cars.

Power without the power cord

Cell phones and flashlights operate by battery without trouble. Yet because of the limited lifespan, battery power is not a feasible option for many applications in the fi elds of medicine or test engineering, such as implants or probes. Researchers have now developed a process that supplies these systems with power and without the power […]
