Mechanisms influencing levitation and the scaling laws in nanopores: Oscillator model theory
Article Abstract:
A detailed theoretical explanation of the floating molecule or levitation effect, for molecules diffusing through nanopores, using the oscillator model theory is described. It is shown that on reduction of pore size, the effect occurs due to decrease in frequency of wall collision of diffusing particles at a critical pore size and mass does not affect the existence of the levitation effect and there exists a scaling of the transport diffusivities with respect to mass, even in the presence of interactions.

Kinetics of oriented aggregation
Article Abstract:
Oriental aggregation is studied which is a special case of aggregation that provides an important route by which nanocrystals grow, defects are formed, and unique, often symmetry-defying, crystal morphologies are produced. The presence of passivating agents may have substantially altered both the association-dissociation of primary particles and the conversion from a complex to oriented aggregates.

Evidence for the monolayer assembly of poly(vinylpyrrolidone) on the surfaces of silver nanowires
Article Abstract:
The preparation of well-defined silver nanowires with five-twinned structure are detailed by polyol reduction in the presence of poly(vinylpyrrolidone). The probable spatial conformation of the PVP molecules is supposed to be that the CH skeleton chain of the PVP is close to the surface of the Ag nanowires.
