Atomistic simulation of orientation of methyl groups and methylene bisectors, and surface segregation, in freely standing thin films of atactic poly(ethylene-co-propylene)
Article Abstract:
Atomistically detailed models of free-standing thin films of random poly(ethylene-co-propylene) are produced with the help of a method recently applied to atactic polystyrene. The findings indicate that the raw experimental data obtained with an increase in ethylene fraction can be explained by the changes in the number of methyl and methylene groups on the surface rather than the increase in surface excess of the methyl groups.

One-step preparation of single-crystalline beta-MnO2 nanotubes
Article Abstract:
Single-crystal beta-MnO2 nanotubes with diameters in the range 200-500 nm and lengths up to several micrometers were successfully prepared by a simple hydrothermal method through oxidizing MnSo4 with NaClO3 in the presence of poly(vinyl pyrrolidone) (PVP). The family of nanotubes offers a possible new, general route to one-dimensional single-crystalline nanotubes of other materials.

Orienting tetracene and pentacene thin films onto friction-transferred poly(tetrafluoroethylene) substrate
Article Abstract:
The mechanism of growth in oriented pentacene thin films deposited onto oriented poly(tetrafluoroethylene) (PTFE) and the effect of several deposition parameters on the morphology and structure of the pentacene thin films is investigated. Results show the possibility to control oriented nucleation via the ledges of a nanostructured and oriented polymer surface.
