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...

Researchers have overcome a major obstacle in efforts to use tiny structures called carbon nanotubes to create a new class of electronics that would be faster and smaller than conventional silicon-based transistors. Carbon nanotubes, which were discovered in the early 1990s, could make possible more powerful, compact and energy-efficient computers, as well as ultra-thin "nanowires" for electronic circuits. The nanotubes might be ideal for future electronics because they conduct electricity...

How do you handle the tiny components needed for constructing nanoscale devices? A European consortium has built two micro-robotic demonstrators that can automatically pick up and install carbon nanotubes thousands of times thinner than a human hair.Carbon nanotubes, rolled up sheets of carbon only a few tens of nanometers in diameter, could become an essential part of the nanotechnologist's construction kit. But there is a problem: how can you handle objects which are so thin that they...

Massachusetts Institute of Technology researchers say they have created carbon nanotubes without using a metal catalyst. The scientists said their finding that oxides, as well as metals, can grow carbon nanotubes changes science's understanding of nanotube growth. Carbon nanotubes -- tiny tubes of graphite -- promise to add speed to electronic circuits and strength to materials such as carbon composites that are used in airplanes and race cars. But the MIT scientists said a major problem has...

 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...
