1. Purified Single-Walled Carbon NanotubesMarcus D. Lay, University of Georgia Research Foundation Inc, DMR 0906564 The development of new methods for the processing of single-walled carbon nanotubes (SWNT) soot is critical to the use of these nanometer sized wires for a wide variety of new materials. We have developed a new method for separating high aspect ratio SWNTs from the many impurities that result from their growth. We have also developed several new methods that allow control over the density, and electrical properties while depositing networks of unbundled SWNTs that can be used in electronic applications N.

Sci., 47, (2012), 3233 Unbundled SWNTs are separated in suspension and then deposited using methods developed by this research group.

2. Purified Single-Walled Carbon NanotubesMarcus D. Lay, University of Georgia Research Foundation Inc, DMR 0906564 This award was used to support the work published in 12 journal articles and 1 book chapter. These manuscripts include 5 undergraduate coauthors, all of whom are from groups that are underrepresented in the sciences. Further, the development of new methods for the control of the physical properties of single-walled carbon nanotubes (SWNTs) in suspensions is critical to the use of these nanometer sized wires for a wide variety of new electronic materials. Professor Lay’s research related to this grant has led to the development of separate undergraduate and graduate courses that rely on recent literature reports to teach the fundamental properties, and potential of electronic nanomaterials. Human resource development has included underrepresented groups at all levels (top) and integration of research and teaching (bottom)
