72. Diffusion and dynamic scaling in concentrated charge-stabilized colloidal suspensions

Gerhard Naegele (Forschungszentrum Jülich, ICS-3)

oral

We present a joint theory, simulation and experimental study of collective and self-diffusion in concentrated suspensions of charged colloidal particles. The study is based on the generalized Smoluchowski diffusion equation accounting both for direct and solvent-mediated hydrodynamic interactions, and it spans the range from the colloidal short-time to the long-time regime. Owing to the large...

87. Exact solution for a $1+1$ etching model.

Fernando Oliveira (Universidade de Brasília)

oral

We present a method to derive analytically the growths exponents of a eroded surface whose dynamics is ruled by cellular automata. Starting from the automata, we write down the time evolution for the height's average and height's variance (roughness). We apply the method to the etching model[1,2] of $1+1$ dimensions, than we obtain the dynamical exponents, which perfectly match the...

23. Subdiffusion in a system consisting of two different media

Tadeusz Kosztolowicz (Institute of Physics, Jan Kochanowski University in Kielce)

oral

We consider subdiffusion in a system which consists of two homogeneous media joined together; subdiffusion parameters can be different in both media [1,2]. We also consider subdiffusion with absorption in a composite system. The application of the theoretical model to describe a real diffusion processes in the considered system is also presented. Confronting the theoretical formulas with the...

3. Random dynamics in a trap: killing vs survival

Piotr Garbaczewski (University of Opole)

oral

We consider the random dynamics in a bounded domain, while concentrating on somewhat unexplored links between the absorbing and inaccessible boundarz data impact upon random motion. Both Brownian and Levy-stable dynamics will be discussed , with a focus on tyhe long term surival, and the permanent trapping scenarios.
