Used tires are first placed in a pyrolysis reactor where they are decomposed into pyrolytic carbon black, heavy oils, and scrap steel. This technology has been successful in removing impurities by further refining the pyrolytic carbon black into carbon black. This carbon black is processed using a unique combustion technology, developed independently by Klean Industries, with CNTs and fullerenes as the end products, 1 kg of CNTs can be produced from 10 kg of carbon black. Reportedly the entire processing line from pyrolysis tire recycling to nanocarbon production systems will be installed at all their facilities in the near future.

Current reports state that Klean Industries has dedicated to process 250,000 tires per year directly for the production of nanocarbons, producing 500t of carbon black and 10t of CNTs. Klean Industries will begin full nano production operations in October 2007.

It featured a half-hour interview with a “big thinker” in science, technology, and other fields. Interviews were filmed in a 16:9 format and intercut with public domain material from the Prelinger Archives. This archival footage (mostly film clips from the 1940′s and 50′s) was used to create visual metaphors highlighting the speaker’s points. This episode features Ralph Merkle. He is a pioneer in public key cryptography, and more recently a researcher and speaker on molecular nanotechnology and cryonics. Merkle graduated from Livermore High School in 1970 and proceeded to study Computer Science at the University of California, Berkeley, obtaining his B.A. in 1974, and his M.S. in 1977. In 1979, he was awarded a Ph.D. in Electrical Engineering at Stanford University, with a thesis titled Secrecy, authentication and public key systems. He was a distinguished professor in the College of Computing at the Georgia Institute of Technology. In addition to his work at Georgia Tech, Merkle is also a director of the Alcor Life Extension Foundation, of Arizona. In industry, Ralph C. Merkle was the manager of compiler development at Elxsi from 1980. In 1988, he became a research scientist at Xerox PARC, until 1999. Subsequently he worked as a nanotechnology theorist for Zyvex, returning to academia in 2003 as a Distinguished Professor at Georgia Tech. www.nanocarbontechnology.com

Fujitsu Laboratories has made a breakthrough in carbon nanotube research.

The company has combined carbon nanotubes and graphene, both of which are nano-scale carbon structures, to self-form a new nano-scale carbon composite, at the relatively low temperature of 510 degrees Celsius.

Graphene is a honeycomb crystal lattice of carbon atoms.

In experiments using chemical vapor deposition, a technique to synthesize thin films and structures on a substrate by thermally decomposing a feedstock gas in a vacuum chamber, Fujitsu Labs discovered that several to dozens of layers of graphene were formed self-organizingly on the vertically aligned multi-walled carbon nanotubes in such a way that they are connected perpendicularly.

It is known that carbon nanotubes are linear, one-dimensional structures, and therefore they nearly lack thermal or electrical conductivity between tubes in the two-dimensional directions perpendicular to the tube axis.

As attention has been paid to heat, how to increase heat radiation is becoming an important issue. The carbon nanotube composite is expected to be a material with high heat radiation capability. Since graphite flows electrons very smoothly, it can also function as a semiconductor.

As an electronics company, Fujitsu Labs aims to use the new structure to improve today’s LSI performance by applying it to dealing with LSI heat radiation and using it in transistors.

While just a test, it’s still an interesting simulation to watch. Three carbon nanotubes are anchored at their ends, and a diamondoid carbon “knife” is pushed down on the nanotubes with a 5 nanonewton force. Will the knife cut through the nanotubes? Watch the video for some nanotube-fu.

The technique lends itself to the creation of new antibacterial and antimicrobial films to help curb the spread of germs, and also holds promise for new methods of seeking out and killing tumors in the human body.
