Oligodeoxyribonucleotide Association with Single-Walled Carbon Nanotubes
Online Presentations | 02 Aug 2007 | Contributor(s):: Jennifer McDonald
Commercially available single-walled carbon nanotubes (SWCNTs) tend to aggregate as ropes and bundles during production making them of little use in many scientific and industrial applications. An effective technique for dispersing and solubilizing SWCNTs is required to fully utilize their unique...

From Research to Learning in Chemistry through Visualization and Computation
Online Presentations | 17 May 2007 | Contributor(s):: Eric Jakobsson
Modern chemistry research and high school chemistry education are separated by institutional and geographical boundaries. As such, much of secondary chemistry education is still based on the periodic table instead of the computational methods that drive current chemistry research. In this talk,...
