ABSTRACT
Tubular shape formation of an ensemble of fine particles captured by a microscopic vortex in a gaseous or fluid medium is investigated. In the circulation flow of the eddy, both the deterministic forces of hydrodynamics and the random forces of Brownian motion drive the small particles. The conditions for dynamically/statistically stable tube formation and the resulting tube parameters are obtained by analytical calculations and computer simulations, respectively. The model answers several key questions of the formation of nanotubes, however, many open questions still remain. © 2000 American Institute of Physics.

    We study the first passage time (FPT) of a particle passing through a subdiffusive membrane; the membrane separates the media where normal diffusion occurs. The transport inside the membrane is described by the subdiffusion equation with fractional time derivative. Outside the membrane the...
