The interlamellar spacing as a function of the surfactant concentration in a lamellar monolayer system containing a ionic surfactant was studied. It is demonstrated that even at large interlamellar spacings (6-14 nm) relative to the Debye lengths (or

We studied the effect of non-adsorbing polymer on the crystallization phenomena of colloidal dispersions. The experiments have been performed on dispersions of monodisperse stearyl silica spheres in cyclohexane to which polystyrene or poly(dimethyl s

Fairly monodisperse colloidal boehmite fibrils with a high aspect ratio were synthesized by hydrothermal treatment at 150°C of an acidified aqueous alkoxide solution, prepared by adding an aqueous HCl solution to an aluminum alkoxide precursor. The

Dispersions of colloidal boehmite (γ-AlOOH) rods (of controllable length) are prepared from alkoxide precursors. A polyisobutene grafting procedure leads to sterically stabilized dispersions. In the organophilic system (L ≈ 200 nm ± 50%; D ≈ 10

The synthesis of colloidal boehmite (AlOOH) is studied by heating basic aluminum chloride solutions under constant stirring. The temperature and Al2O3: Cl molar ratio influence the product morphology. Synthesis at 140°C generates highly fibrous poly

We summarize and discuss the short time analogies between concentrated charged colloidal suspensions and dense atomic liquids known in the literature and introduce a new analogy between both systems which is valid for long times. This new analogy agr

The interfacial tension of a demixed colloid-polymer mixture is measured using the spinning drop technique. For a demixed system of colloidal silica (diameter 20 nm) and polydimethylsiloxane (M w =97000) in cyclohexane a value of 1.5× 10−2 mN/m is
