Palladium Nanoparticle Electrodeposition on Nanotubes Results in New Flexible Hydrogen Sensors

(Phys.org) —Researchers at Yale University have taken another step toward the development of low-temperature, lower-cost alkaline fuel cells, which are battery-like devices that convert oxygen and hydrogen ...

A team of Northern Illinois University scientists, with a major role played by NIU Ph.D. students, has discovered a new, convenient and inexpensive way to make high performance hydrogen sensors using palladium nanowires.

(Phys.org)—Band-​​aid tech­nology has made incre­mental improve­ments in the years since its com­mer­cial intro­duc­tion in the late 1960s, the most impor­tant of which has been the incor­po­ra­tion ...

(PhysOrg.com) -- Such highly coveted technical capabilities as the observation of single catalytic processes in nanoreactors, or the optical detection of low concentrations of biochemical agents and gases ...

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed new ways to make or modify nanorods and nanotubes of titanium oxide, a material used in a variety of industrial and ...

In recent years, Americans have been intrigued by the promise of hydrogen-powered vehicles. But experts have judged that several technology problems must be resolved before they are more than a novelty.

(Phys.org) —Graphene has dazzled scientists, ever since its discovery more than a decade ago, with its unequalled electronic properties, its strength and its light weight. But one long-sought goal has proved ...

(Phys.org) —In the wake of the sobering news that atmospheric carbon dioxide is now at its highest level in at least three million years, an important advance in the race to develop carbon-neutral renewable ...

Nanotechnology draws on the fabrication of nanostructures. Scientists have now succeeded in growing a unique carbon structure at the nanoscale that resembles a tiny twirled mustache. Their method might lead ...

A team of researchers from Columbia University, City University of New York, the University of Central Florida (UCF), and Tohoku University and the National Institute for Materials Science in Japan, have ...

Whether in vehicle transmissions, hip replacements, or tiny sensors for triggering airbags: The respective components must slide against each other with minimum friction to prevent loss of energy and material ...

Nanotubes are stronger than steel and smaller than any element of silicon-based electronics. They can potentially process information faster while using less energy. The challenge has been figuring out how ...
