Study of the polydispersity of grafted poly(dimethylsiloxane) surfaces using single-molecule atomic force microscopy
Article Abstract:
Atomic Force Microscopy has great scope to analyze contour lengths of polymers/macromolecules at surfaces. The values of persistence, lengths and other parameters obtained from filling the force-distance profiles indicate that the measurements typically involved stretching single PDMS molecules grafted to the underlying surfaces.

Molecule corrals as templates for the formation of metal and silicon nanostructures
Article Abstract:
Gold and silicon nanostructures are produced by condensing vacuum-evaporated materials onto nanometer-sized etch-pit templates performed on the surface of highly oriented pyrolytic graphite. Scanning tunneling spectroscopy is used to further investigate the electronic properties of multilayered silicon nanostructures.

Perturbations of the fully resolved eletronic spectra of large molecules by the internal rotation of attached methyl groups: influence of complex formation
Article Abstract:
The barrier to internal rotation of a methyl group attached to an unsaturated linkage in an organic molecule is changed by complex formation with a weakly bound argon atom. This is a result of a dispersion interaction between the argon and pie-electrons of the molecule in the vicinity of the methyl group.
