Nanochemists Discover Novel, Semi-Conducting Nanotube

A UALR chemistry professor working with colleagues at Stanford University has developed a technique that could break through the bottleneck that so far has stymied the scientific quest to create a new generation of electronic systems on the nano-scale.

Dr. Wei Zhao, professor in UALR’s Department of Chemistry in the College of Science and Mathematics, and his graduate student Xiaomin Tu, now a postdoctoral fellow at DuPont Central Research and Development, Wilmington, Del., are co-authors of an article in the latest edition of the Journal of the American Chemistry Society on the ability to achieve near single type purity nanotube production.

The availability of pure single-wall nanotubes will greatly enhance the creation of new products useful for the consumer, said Dr. Michael Gealt, dean of the College of Science and Mathematics at UALR.

The UALR-Stanford discovery has generated major buzz in chemical and nanotechnology circles.

“The day of being able to pick and choose single-walled nanotubes with defined electrical properties may soon be upon us,” said science writer Jon Evans, reviewing the discovery in the Ion Chromatography, an online science magazine.

The paper is published online at the website for the American Chemical Society.
