Opis:: Structure and dynamics of suspensions of charged colloidal spheres in water were studied by means of small-angle X-ray scattering and X-ray photon correlation spectroscopy using synchrotron radiation. Experimentally obtained dependences on the scattering vector q of the structure factor S(q), short-time collective diffusion coefficient D(q) and hydrodynamic function H(q) were in good agreement with theoretical predictions. No effect of screening of the hydrodynamic interactions, suggested in the literature, was found. The conditions are discussed at which the maximum of the hydrodynamic function peak value H(q_m) can be obtained experimentally.

Opis:: Novel simulation procedure of self-diffusion through model porous media is presented. The procedure is based on extensive use of molecular dynamic method. The introduced diffusion simulations have a potential to become a valuable design and development tool applications involving transport in porous media, e.g. filters or porous sensors. The porous membranes are created using phase-separating model with high surface tension and its properties are characterized and compared with existing porosimetry measurements and small angle scattering experiments. These membranes are then filled with a gas of diffusing particles. Relations between transport coefficients and material structure are discussed.

Opis:: Dielectric relaxation studies for mixtures of strongly polar and mesogenic n-heptylcyanobiphenyl with non-polar and non-mesogenic carbon tetrachloride (CCl$\text{}_{4}$) were performed. The absorption band broadening due to fractional diffusion was observed. A correlation between the non-mesogenic admixture concentration and the anomalous diffusion exponent was found.
