Molecular beam-controlled nucleation and growth of vertically aligned single-wall carbon nanotube arrays
Article Abstract:
A growth method for single-wall carbon nanotubes that uses molecular beams of precursor gases that impinge on a heated substrate coated with a catalyst thin film is described. It is observed that the incidence rate of acetylene molecules plays a critical role in the formation of single-wall carbon nanotubes and that the growth rate, the diameter and the number of walls of the nanotubes are systematically correlated with the acetylene incidence rate and the substrate temperature.

Theory of structure-based carbon nanotube separations by ion-exchange chromatography of DNA/CNT hybrids
Article Abstract:
A DNA/carbon nanotube (CNT) hybrid elutes at an ionic strength that depends on the electronic character and diameter of the core nanotube provides a mechanism for separating nanotubes by chirality. A theoretical model for this separation process that explains all the salient features observed experimentally and provides accurate predictions for critical elution salt concentration is presented.

Deformation of a sheet with coupling between elasticity and concentration
Article Abstract:
A simple model is developed and examined for equilibrium deformation of a sheet with concentration-dependent elasticity. It is shown that the sheet has responded to imposed distortion by rearranging its constituents and can be done in a small and stable manner only for small distortion.
