Opis:: The mobility of the 100 nm $Fe_2O_3$ particles in dense water solutions of sugar (sucrose) was determined from the analysis of the resonance absorption line shape of the Mössbauer spectra recorded in the -5°C to 40°C temperature range for different sugar concentrations. The discrepancy between the experimental data and the prediction of the classical theory of Brownian movement are interpreted in the term of the short observation time and the interaction between the solid particles in fluids, which extends in water up to 300 nm. The sedimentation process in the studied colloids was observed.

Opis:: The 100 nm particles of $Fe_{2}O_{3}$ and metallic Fe sedimented jointly with $Al_{2}O_{3}$ powder from their suspension in oleic acid exhibit distinguished mobility which depends on the concentration of aluminum oxide. This observation is interpreted as the result of the interparticle Fe-Fe magnetic interactions which lead to the formation of the rigid network of magnetic metallic iron nanoparticles.

Opis:: In order to survive the competition, the processing cycle time and the energy consumption of the rotational foam molding process must be reduced to a fraction of its current levels without compromising product quality. This paper introduces a novel extrusion-assisted rotational foam molding process for the manufacture of rotational moldings having adjacent, but clearly distinct, layers of an integrated solid (non-cellular) skin boundary layer encapsulating a cellular core structure, consisting of identical or compatible polyolefin grades, that achieves significant savings in processing cycle time duration and energy consumption. It introduces non-chilled extruded foam as a foamed core-forming material, in real time, directly into a uni-axially rotating hot mold through a dedicated mold "injection" port onto the already formed un-foamed soft skin layer.
