Cheap hybrid outperforms rare metal as fuel-cell catalyst

Graphene quantum dots created at Rice University grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, making them better than platinum catalysts for certain reactions within fuel cells.

Greener low-cost transistor heralds advance in flexible electronics

Researchers report a new, inexpensive and simple way to make transparent, flexible transistors that could help bring roll-up smartphones with see-through displays and other bendable gadgets to consumers in just a few years.

Toward making lithium-sulfur batteries a commercial reality

Scientists are now reporting they have overcome key obstacles toward making lithium-sulfur batteries, which have the potential to leave today's lithium-ion technology in the dust.

Tattoo biobatteries produce power from sweat

Researchers reported that they have designed a sensor in the form of a temporary tattoo that can both monitor a person's progress during exercise and produce power from their perspiration.

Copper shines as flexible conductor

A new way of working with copper nanowires and a PVA "nano glue" could be a game-changer.

Could hemp nanosheets topple graphene for making supercapacitors?

Scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors.

ABB and Volvo global partnership for electric, hybrid bus fast charge

ABB has announced a partnership with Volvo Buses, one of the world's leading bus manufacturers, to co-develop and commercialize electric and hybrid buses with open standards-based direct current (DC) fast charging systems.
