Latest carbon nanotubes Stories
 Carbon nanotubes "” tiny, rolled-up tubes of graphite "” promise to add speed to electronic circuits and strength to materials like carbon composites, used in airplanes and racecars. A major problem, however, is that the metals used to grow nanotubes react unfavorably with materials found in circuits and composites. But now, researchers at MIT have for the first time shown that nanotubes can grow without a metal catalyst. The researchers demonstrate that zirconium oxide, the same...
Rice scientists use nanomaterials to grow flying carpets, 'odako' kitesWith products that range from carpets to kites, you'd think Rice University chemist Bob Hauge was running a department store. What he's really running is a revolution in the world of carbon nanotechnology. In a paper published this month in Nano Research, Hauge's Rice University team describes a method for making "odako," bundles of single-walled carbon nanotubes (SWNT) named for the traditional Japanese kites they...
New video showing the atom-by-atom growth of carbon nanotubes reveals they rotate as they grow, much like the halting motion of a mechanical clock's second hand. FEM video from Université Lyon1/CNRS shows the rotation of the nanotube during growth. The observation helps confirm a new rotational theory of carbon nanotube growth offered by Rice researchers in February.Published online this month by researchers at France's Université Lyon1/CNRS and Houston's Rice University, the research...
Researchers at TU Delft have succeeded in measuring the influence of a single electron on a vibrating carbon nanotube. This research can be important for work such as the development of ultra-small measuring instruments. The scientists have published their results on Thursday 23 July in (the online version of) the scientific journal Science.The scientists of the Kavli Institute for Nanoscience at TU Delft based their project on a suspended vibrating carbon nanotube, comparable to an...
Physics professor at UH uses Air Force grants to create highly conductive nanocompositesIf one University of Houston professor has his way, the inexpensive plastic now used to manufacture CDs and DVDs will one day soon be put to use in improving the integrity of electronics in aircraft, computers and iPhones.Thanks to a pair of grants from the U.S. Air Force, Shay Curran, associate professor of physics at UH, and his research team have demonstrated ultra-high electrical conductive properties...
Researchers at UCLA have developed a new method for producing a hybrid graphene"“carbon nanotube, or G-CNT, for potential use as a transparent conductor in solar cells and consumer electronic devices. These G-CNTs could provide a cheaper and much more flexible alternative to materials currently used in these and similar applications.Yang Yang, a professor of materials science and engineering at the UCLA Henry Samueli School of Engineering and Applied Science and a member of UCLA's...
Researchers at Sandia National Laboratories have created the first carbon nanotube device that can detect the entire visible spectrum of light, a feat that could soon allow scientists to probe single molecule transformations, study how those molecules respond to light, observe how the molecules change shapes, and understand other fundamental interactions between molecules and nanotubes.Carbon nanotubes are long thin cylinders composed entirely of carbon atoms. While their diameters are in the...
CLEVELAND, March 11 /PRNewswire-FirstCall/ -- PolyOne Corporation (NYSE: POL), a premier provider of specialized polymer materials, services and solutions, and Zyvex Performance Materials, a recognized worldwide leader in carbon nanotube-enhanced applications, today announced a joint development agreement to provide carbon nanotube-filled polymer materials for structural and electrically conductive applications. PolyOne will compound the functionalized nanotubes with a variety of...
 New research from Rice University and the University of Oulu in Oulu, Finland, finds that carbon nanotubes could significantly improve the performance of electrical commutators that are common in electric motors and generators.The research, which appeared online this month in the journal Advanced Materials, finds that "brush contact" pads made of carbon nanotubes had 10 times less resistance than did the carbon-copper composite brushes commonly used today. Brush contacts are...
LONDON, Feb. 18 /PRNewswire/ -- Carbon nanotubes (CNTs) are the most popular and recognizable elements of present nanotechnology. Scientists and researchers now are discovering that carbon nanotubes could be more affordable and useful to many industrial areas, including flame retardant materials market. (Logo: http://www.newscom.com/cgi-bin/prnh/20081117/FSLOGO) The global flame retardant chemicals market is valued at just under $3 billion, with demand for non-flammable products ever...
