Texas, California Inventors Develop Single-Wall Carbon Nanotube Making Method

ALEXANDRIA, Va., March 21 -- Richard E. Smalley, Daniel T. Colbert, Andrew G. Rinzler, Pavel Nikolaev and Andreas Thess, all from Houston, and Ting Guo of San Diego, have developed a carbon nanotube making method.According to the U.S. Patent & Trademark Office: "This invention provides a method of making single-wall carbon nanotubes by laser vaporizing a mixture of carbon and one or more Group VIII transition metals. Single-wall carbon nanotubes preferentially form in the vapor and the one or more Group VIII transition metals catalyzed growth of the single-wall carbon nanotubes."

Laser scanning robot 3D-R1 used to map mines

A UK-based company, 3D Laser Mapping, has developed robots equipped with lasers to automatically scan mines. Its latest mission was to create a 3D map of the San Jose silver mine in Mexico. The remote survey vehicle (RSV) 3D-R1 weighs about 135 kilograms and is 0.6 meter high. It has a width of 0.9 meter and a length of 1.1 meter. For its Mexican mission, the RSV captured about 100 million data points in about 3 days. And it delivered a full 3D vision of the silver mine, including an accurate volumetric calculation of previously ‘worked’ areas. As wrote the 3D Laser Mapping’s owner in a previous document, ‘We already have laser scanners in aircraft, ground vehicles and even robots, what comes next could be down to you.’ But read more…

Carbon nanotube technology could su..

Just as silicon is the wonder material of the computer age, carbon nanotubes will most likely be the materials responsible for the next evolutionary step in electronics and computing. Their extraordinary properties have identified them as having the potential to revolutionize many technologies. In particular, it is widely believed that carbon nanotubes will take electronic devices to the next level. Many people expect the hugely popular LCD and plasma screens to be replaced by field emission flat screen displays (FED-TV). FED-TV's combine all the best aspects of CRT's, LCD's and plasma TV's into a single package. While the technology exists, manufacturers are at present unable to compete with LCD's and plasma displays on a cost basis. However, carbon nanotubes have the ability to change all that.

Nanomotor provides linear or rotary motion

Researchers from the Spanish National Research Council, Universitat Autònoma de Barcelona, and the Catalan Institute of Nanotechnology claim to have created the first nanomotor that is moved by changes in temperature. The 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 is said to open the door to the creation of new nano-scale devices designed to carry out mechanical tasks, which, in the future, could be applied to the fields of biomedicine or new materials. The 'nanotransporter' consists of a carbon nanotube - a cylindrical molecule formed by carbon atoms - covered with a shorter concentric nanotube that can move back and forth or act as a rotor.

Carbon nanotubes send electrons for a spin

The crystalline carbon family is the subject of a determined research effort because the unique bonding features of carbon give it some very special properties. For instance, diamond is an extremely rigid semiconductor with a large bandgap. This means that, if you can set the atomic state of a single carbon atom within a diamond crystal, it will remain that way for quite a while as the structural rigidity prevents the atoms from strongly interacting with each other. Another form of carbon, graphite, is a series of loosely connected sheets. Electrons can flow within each sheet, making it a conductor. In addition, a single sheet, called graphene, has the remarkable property that the angular momentum of an orbiting electron is independent of its spin.

Carbon nanotubes outperform copper nanowires as interconnects

14 March 2008 Researchers at Rensselaer Polytechnic Institute have created a road map that brings academia and the semiconductor industry one step closer to realizing carbon nanotube interconnects, and alleviating the current bottleneck of information flow that is limiting the potential of computer chips in everything from personal computers to portable music players. To better understand and more precisely measure the key characteristics of both copper nanowires and carbon nanotube bundles, the researchers used advanced quantum-mechanical computer modelling to run vast simulations on a high-powered supercomputer. It is the first such study to examine copper nanowire using quantum mechanics rather than empirical laws.

Levels of Carbon Dioxide in Atmosphere Increase

Atmospheric levels of carbon dioxide, the principal heat-trapping gas, are continuing to rise at an accelerating rate, the National Oceanic and Atmospheric Administration reported. And after a decade of stability, levels of an even more potent heat-trapper, methane, rose as well. The agency said atmospheric levels of carbon dioxide reached nearly 385 parts per million last year, up from 280 in 1850 and an increase of 2.6 parts per million from 2006, chiefly from the burning of fossil fuels. The methane situation is less clear. Methane is produced naturally by swamps but also by activities including burning fossil fuels. The issue is important because climate experts have long worried that if Arctic permafrost thaws, the process would release potentially catastrophic amounts of methane into the atmosphere.

Nanochemistry inside carbon nanotubes

(Nanowerk Spotlight) As far as test tubes go, it doesn't get any smaller than a single-walled carbon nanotube (SWCNT). Among the wide range of interesting properties exhibited by SWCNTs is their capacity to encapsulate molecules within their quasi one-dimensional cavity. The confinement offered by the nanotube could serve as a nanoscale test tube to constrain a chemical reaction. This was demonstrated in principle back in 1998, when the coalescence of adjacent fullerenes was observed by transmission electron microscopy ("Encapsulated C60 in carbon nanotubes"). In the following years, scientists have extensively experimented with filling nanotubes with other fullerenes, atoms, molecules and, very recently, with organic molecules. Owing to their large variety with diverse chemical properties, the incorporated organic molecules can tune the
