Rice researchers spin pure batches of nanotubes species In two new papers, Rice University researchers report using ultracentrifugation (UCF) to create highly purified samples of carbon nanotube species. One team, led by Rice Professor Junichiro Kono and graduate students Erik Haroz and William Rice, has made a small but significant step toward the dream of an efficient nationwide electrical grid that depends on highly conductive quantum nanowire. The other, led by Rice Professor Bruce...

Team of more than 20 researchers directed white blood cells containing the oxidizing enzyme "myeloperoxidase" to attack nanotubes, reducing their unhealthful effects and prompting natural biodegradation, says report in "Nature Nanotechnology" An international study based at the University of Pittsburgh provides the first identification of a human enzyme that can biodegrade carbon nanotubes-the superstrong materials found in products from electronics to plastics-and in laboratory tests offset...

A team of Swedish and American scientists has shown for the first time that carbon nanotubes can be broken down by an enzyme - myeloperoxidase (MPO) - found in white blood cells. Their discoveries are presented in Nature Nanotechnology and contradict what was previously believed, that carbon nanotubes are not broken down in the body or in nature. The scientists hope that this new understanding of how MPO converts carbon nanotubes into water and carbon dioxide can be of significance to...

A closer look at a promising nanotube coating that might one day improve solar cells has turned up a few unexpected wrinkles, according to new research* conducted at the National Institute of Standards and Technology (NIST) and North Dakota State University (NDSU)"”research that also may help scientists iron out a solution. The scientists have found that coatings made of single-walled carbon nanotubes (SWCNTs) are not quite as deformable as hoped, implying that they are not an easy...

Current body protheses do not last more than 10-15 years. After this time, the operation has to be repeated in order to change prothesis. It is usually problematic as, in general, it is elderly people that use the procedure. Researcher Nere Garmendia, based in the Basque city of Donostia-San Sebastián, has just published her PhD, a thesis which may well mean the first step to solving this problem. According to Ms Garmendia, using a ceramic material called zirconia (Zr02), carbon...

Phase transitions "“ changes of matter from one state to another without altering its chemical makeup "“ are an important part of life in our three-dimensional world. Water falls to the ground as snow, melts to a liquid and eventually vaporizes back to the clouds to begin the cycle anew. Now a team of scientists has devised a new way to explore how such phase transitions function in less than three dimensions and at the level of just a few atoms. They hope the technique will be...

Dry printing of nanotube patterns to any surface could revolutionize microelectronics and more Watch a gecko walk up a wall. It defies gravity as it sticks to the surface no matter how smooth it appears to be. What's happening isn't magic. The gecko stays put because of the electrical attraction "“ the van der Waals force "“ between millions of microscopic hairs on its feet and the surface. The principle applies to new research at Rice University reported this week in the online...

Most people would like to be able to charge their cell phones and other personal electronics quickly and not too often. A recent discovery made by UC San Diego engineers could lead to carbon nanotube-based supercapacitors that could do just this. In recent research, published in Applied Physics Letters, Prabhakar Bandaru, a professor in the UCSD Department of Mechanical and Aerospace Engineering, along with graduate student Mark Hoefer, have found that artificially introduced defects in...

Rice University scientists yesterday unveiled a method for the industrial-scale processing of pure carbon-nanotube fibers that could lead to revolutionary advances in materials science, power distribution and nanoelectronics. The result of a nine-year program, the method builds upon tried-and-true processes that chemical firms have used for decades to produce plastics. The research is available online in the journal Nature Nanotechnology. "Plastics is a $300 billion U.S. industry because of...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
