Some of the planet´s tiniest inhabitants may help address two of society´s biggest environmental challenges:  how to deal with the vast quantities of organic waste produced and where to find clean, renewable energy. According to César Torres and Sudeep Popat, researchers at Arizona State University´s Biodesign Institute, certain kinds of bacteria are adept at converting waste into useful energy.  These microorganisms are presently being applied to the...

The Elsevier journal Reinforced Plastics reported that Zyvex Technologies' Piranha, a 54 ft unmanned boat built using carbon nanotube strengthened prepreg, has completed sea trials which demonstrate record fuel efficiency. Piranha is an unmanned surface vessel (USV) designed to enable a broad range of operations at sea with reduced operational costs and risks to sailors. The ground-breaking research that make such advances possible are reviewed in new and forthcoming books from Elsevier's...

Stretching could improve efficiency of material used in batteries, fuel cells and water purification Researchers at Virginia Tech in Blacksburg, Va. recently found a way to improve electricity generating fuel cells, potentially making them more efficient, powerful and less expensive. Specifically, they discovered a way to speed up the flow and filtering of water or ions, which are necessary for fuel cells to operate. Simply put, the researchers stretched Nafion, a polymer electrolyte...

Designing new materials depends upon understanding the properties of today's materials. One such material, Nafion ©, is a polymer that efficiently conducts ions (a polymer electrolyte) and water through its nanostructure, making it important for many energy-related industrial applications, including in fuel cells, organic batteries, and reverse-osmosis water purification. But since Nafion was invented 50 years ago, scientists have only been able to speculate about how to...

Composite materials generate electricity, reveal impact forces As athletes strive for perfection, sports scientists need to exploit every technological advance to help them achieve that goal. Researchers in New Zealand have now developed a new type of wearable impact sensor based that can provide much needed information about the stresses and strains on limbs for rugby players, high jumpers, and runners. Writing in the International Journal of Biomechatronics and Biomedical Robotics, Kean Aw...

A new type of membrane based on tiny iron particles appears to address one of the major limitations exhibited by current power-generating fuel cell technology.While there are many types of fuel cells, in general they generate electricity as the result of chemical reactions between an external fuel -- most commonly hydrogen -- and an agent that reacts with it. The membrane that separates the two parts of the cell and facilitates the reaction is a key factor in determining the efficiency of the...
