Since its discovery just a few years ago, graphene has climbed to the top of the heap of new super-materials poised to transform the electronics and nanotechnology landscape. As N.J. Tao, a researcher at the Biodesign Institute of Arizona State University explains, this two-dimensional honeycomb structure of carbon atoms is exceptionally strong and versatile. Its unusual properties make it ideal for applications that are pushing the existing limits of microchips, chemical sensing instruments,...

The motor functions as a nanotransporter by moving and rotating cargo from one end of the carbon nanotube to the otherResearchers from the UAB Research Park have created the first nanomotor that is propelled by changes in temperature. A carbon nanotube is capable of transporting cargo and rotating like a conventional motor, but is a million times smaller than the head of a needle. This research opens the door to the creation of new nanometric devices designed to carry out mechanical tasks and...

ARGONNE, Ill. (August 30, 2005) "“ Researchers at the U.S. Department of Energy's Argonne National Laboratory have combined the world's hardest known material "“ diamond "“ with the world's strongest structural form "“ carbon nanotubes. This new process for "growing" diamond and carbon nanotubes together opens the way for its use in a number of energy-related applications. The technique is the first successful synthesis of a diamond-nanotube nanocomposite, which means...

EVANSTON, Ill. --- Since the invention of the atomic force microscope (AFM) in 1986 by Nobel laureate Gerd Binnig, the tool has been employed to advance the science of materials in many ways, from nanopatterning (dip-pen nanolithography) to the imaging of surfaces and nano-objects such as carbon nanotubes, DNA, proteins and cells. In all these applications, the quality and integrity of the tip used to obtain the images or interrogate materials is paramount. A common problem in atomic force...
