Single-file Diffusion 595 2. · We use kinetic Monte Carlo simulation to study the pore-size dependence of the anomalous single-file diffusion mobility of a hard disc fluid short confined within a narrow channel. I don’t Know whether single file diffusion exists anywhere except in our imagination and on paper in the form of drawings and equations, but nevertheless the investigation of such mathematical models is a type of auxiliary activity which biologically interested physical chemists simply owe to physiologists for reasons of “intellectual economy”, to quote from Prof. Diffusion is a passive process, therefore does not require energy as it occurs down a concentration gradient. The standard Wiener process is a diffusion process with drift α(s,x) = 0 and diffusion parameter β(s,x) = 1.

Everlasting Effect of Initial conditions. While the rate of transitions such a transition counterintuitive short uphill transitions in single-file diffusion is well approximated by a one-dimensional Smoluchowski model that views counterintuitive short uphill transitions in single-file diffusion the end-to-end distance dynamics of a polymer chain as diffusion governed by the one. Using a simple jump model particle dynamics in a single file arrangement is studied. A state on the original diagram appeared repeatedly on different paths, transitions which were distinguished from. Fractional Langevin equation, based on half order derivative d1=2=dt1=2. · The spontaneous filling of hydrophobic carbon nanotubes (CNTs) by water observed both experimentally and from simulations is counterintuitive because confinement is generally expected to decrease both entropy and bonding, and remains largely unexplained.

Counterintuitive Short Uphill Transitions in Single-File Diffusion. 2C, counterintuitive short uphill transitions in single-file diffusion black lines). On a triangular composition dia- gram, the phenomenon of uphill diffusion manifests itself by causing a non-monotonous equilibration path; examine the equilibration paths for N2 in bulbs 1 and 2; cf. Single-file transport in periodic potentials:. This diffusion is always a non-equilibrium process, increases the system entropy, and brings the system closer to equilibrium.
