On the swelling of monoolein liquid-crystalline aqueous phases in the presence of distearoylphosphats that the C. phase is favoured and expands on the expense of the C. phase. Furthermore, at a high DSPG content (about 5 wt%) the C. phase can take about 60% water. This cubic phase is transformed into a highly swollen lamellar phase, which exists from just below 70 wt% water and up to about 80 wt%

Environmentally benign nonionic surfactant systems for use in highly alkaline mediarfactant named alkyl glucoside, which has a polyhydroxyl functionality as its hydrophilic part arising from natural sources such as carbohydrates, offers better solubility as well as strong surface activity. When combining these two categories of surfactants good solubility in, for instance, alkali,

Sorption and catalytic properties of Latvian clay powdersctite) ex hibit a characteristic shoulder at the closure of the hysteresis loop of the sorption isotherms. This corresponds to the maximum on the curve of pore size distribution which was due to the presence of slit-shaped pores. Increasing the treatment temperature decreases the magnitude of the sp

Effect of reaction variables on the formation of silica particles by hydrolysis of tetraethyl orthos, the conversion of TEOS to silica was low; however, the amount of silica formed increased in proportion to the concentration of NaOH. Our interpretation is that hydroxyl ions are consumed during the hydrolysis reaction, leading to the formation of charged intermediates. When most of the hydroxyl io

Interactions between surfaces coated with cationic hydrophobically modified polyelectrolyte in the purfactant is incorporated in the adsorbed layer even at very low bulk concentrations. As the surfactant concentration is increased stepwise the layer first swells and relaxes very slowly during compression. At higher SDS concentrations, desorption occurs. The interfacial properties of the hydrophobi

Ideal (Langmuir-type surface and electric properties of ,- isopropylphosphine oxide at the air/water are mainly due to the ellipsoidal hard-sphere-like structure of the molecule delimited by the isopropyl chain, which determines the closest packing density of the adsorbate. This is justified by the minimum cross-sectional area of about 80 Å./molecule adsorbed, which corresponds to a sphere delimit
