The NASA Goddard Space Flight Center has a team of scientists testing micro and nano technology to use on spacecraft. The goal is to reduce the reflection off the surface of the instruments so that the data does not get polluted by the scattered light. The carbon nanotubes that the team grows have proven to be 10 times better than the NASA Z306 paint, currently used on spacecraft instruments. The nanotubes are also very robust and can be grown on different materials. The team is really close to getting the carbon nanotubes approved for spaceflight.

Dmitri Tsyboulski performs single nanotube experiment with tunable Ti:Sapphire laser Trestles Finesse. More details on related research can be found on Professor Bruce Weisman website. Dr. R. Bruce Weisman and his group investigate the spectroscopy and photophysics of fullerenes and carbon nanotubes. All of these are closed nanoscopic structures formed from carbon atoms. Fullerenes, such as C60, C70, and their chemical derivatives, have unusual molecular properties that cause interesting behaviors following the absorption of light. Time-resolved absorption and emission methods are used to study radiationless decay, photochemical reactions, and energy transfer in fullerenes. Another major research topic is single-walled carbon nanotube spectroscopy. Following the discovery in Weisman?s lab of near-infrared nanotube fluorescence, the group has measured and unraveled the absorption and emission spectra of more than 30 semiconducting nanotube species. Follow-up projects include detailed elucidation of nanotube electronic structure, as well as applications in non-invasive biomedical imaging and analytical nanotechnology. Few publications and abstracts are cited below: Laurent Cognet, Dmitri A. Tsyboulski, John-David R. Rocha, Condell D. Doyle, James M. Tour and R. Bruce Weisman “Stepwise Quenching of Exciton Fluorescence in Carbon Nanotubes by Single Molecule Reactions.” Science, 316 (2007): 1465-1468.

A “nanohand” is a small gripper, small enough to manipulate nanotubes and nanofibres. This movie show how to pick and place nanofibres using a nanohand, to construct a nanodevice: a super-probe for atomic force microscopy. It takes a lot of work to get this far; and much more to get further: how about a virtual reality world where you can pick nanotubes with your own hands, while the nanogripper does it with 10000 times smaller fingers? How about an assembly line, a factory for building nanotube devices? Two big european projects, Nanorac and Nanohand, are now trying to make this reality. The video was filmed by Volkmar Eichhorn at Oldenburg University in their cool nanorobot-in-a-microscope system, using the new microgrippers from DTU, designed by Kenneth Carlson. The work was published here: Nanotechnology 18 2007, page 345501. Want to know more? Check nanosystemsengineering.dk/index_pages/nanogripper.htm

All about carbon Nanotubes!

Once again NanoDays introduced us to dozens of researchers studying the very small. We learned about nanotubes in space, the “magic” of quantum dots, and nano-biotechnology.
