Researcher discovers new materials

11.07.2006
Nanostructured materials developed

A research team led by Carnegie Mellon University Materials Science and Biomedical Engineering Professor Prashant Kumta has discovered a nanocrystalline material that is cheaper, more stable and produces a higher quality energy storage capacity for use in a variety of industrial and portable consumer electronic products. Kumta said the discovery, published this summer in Advanced Materials Journal, has important implications for increasing the longevity of rechargeable car batteries, fuel cells and other battery-operated electronic devices.

"We have found that synthesis of nanostructured vanadium nitride and controlled oxidation of the surface at the nanoscale is key to creating the next generation of supercapacitors commonly used in everything from cars, camcorders and lawn mowers to industrial backup power systems at hospitals and airports," Kumta said.

Dramatic growth in computer use is making consumers require more from their electronic devices, which creates increased demand for a better power source than existing battery technology. Today's batteries are also powered by ruthenium, which sells for $100 per gram, compared with the more economical vanadium nitride at $50 a gram.

"Not only is vanadium nitride less expensive to use, it can also store energy much longer, giving users a greater burst of juice for the old finicky car battery or the hospital's backup power system," Kumta said.

As people use cell phones to do more than just communicate -- as they watch movies, listen to music and process family photos -- they need more power. And this new nanocrystalline will solve some of those challenges, according to Kumta.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
