Creativity provides Tour with nano car


09/01/2006







It’s not surprising that the world’s first nanocar would be invented by the Tour group. Jim Tour’s single-molecule nanocar made headlines late last year, not only in Nano Letters, where “Directional Control in Thermally Driven Single-Molecule Nanocars” was the single most-accessed paper in all American Chemical Society journals for the entire year, but in publications as diverse as The New York Times and Popular Mechanics.

For a dubious public, a cool and easily understood gadget like the nanocar is just the thing to help explain why nanotechnology is potentially so useful. And the nanocar is a terrific test object for figuring out how to make molecules do what scientists and engineers want.


The nanocar earned Tour, the Chao Professor of Chemistry at Rice University and the director of the Smalley Institute for Nanoscale Science and Technology, an Innovation Award from Honda in 2005, as well as a Southern Chemist of the Year Award from the American Chemical Society.


The Tour group spent eight years perfecting the techniques used to make the nanocar, which has a chassis and freely rotating axles made of well-defined organic groups, with wheels made of Buckyballs. The entire car measures three to four nanometers across, and 30,000 of them could park in the width of that ubiquitous human hair. The trickiest part was attaching the wheels without destroying the rest of the car.


The group has already followed up the nanocar paper with another describing a light-driven motorized nanocar. Their objective is the eventual development of nanomachines for bottom-up manufacturing, in much the same way that nature uses enzymes.

Tour also has made it his mission to demystify nanotechnology for kids His NanoKids educational outreach program expresses complex chemical and physical concepts in accessible, videogame-style tools, for grades 6 through 12. The idea came to him when his six-year-old started doodling arms and legs onto a sketch of an organic molecule. The units are being tested this year with 9,000 students in 28 middle schools.

Pradeep Haldar, professor of nanoengineering at the College of Nanoscale Science and Engineering at the State University of New York at Albany, has made it his mission to produce “industry-ready” graduates for the nanotech sector. He established his school’s Nanotechnology Management Program, nicknamed “Nano+MBA,” which enrolled its first students this year.
