    Gas adsorption by a crystalline silicic acid (1989)
    Springer
    Colloid & polymer science 267 (1989), S. 844-852 
    Details
    ISSN: 1435-1536
    Keywords: Crystalline silicic acid ; gas adsorption ; microporosity ; silica ; surface area
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Crystalline silicic acids are prepared from alkali layer silicates by exchanging protons for the alkali ions. The acid H2Si20O41 · xH2O (parent material K2Si20O41 · xH2O) exhibits some outstanding gas adsorption properties which are related to the layer structure and the interlamellar microporosity. The external surface, about 20 m2 g−1, is estimated from nitrogen adsorption data after blocking the micropores. Slit-shaped ultramicropores (with diameters similiar to that of the nitrogen molecule) between the layers are widened to supermicropores near the crystal edges. During an adsorption run the nitrogen molecules penetrate more deeply into the ultramicropores. Nitrogen molecules strongly adsorbed in the ultramicropores are not desorbed at 77 K. Additional amounts of nitrogen are adsorbed by widening of the slit-shaped micropores at the crystal edges when pressure increases. This process proceeds slowly and is reversible.

    Some aspects of polymer colloids I. Preparation and properties of different types of latex particles (1990)
    Springer

    ISSN: 1435-1536

    Notes: Abstract The boundary region separating a latex particle from the surrounding medium has a great influence on the properties of latex dispersions. Four types of polystyrene and polystyrene/comonomer latices differing greatly in the structure of the boundary region were prepared. The first part of a series of papers reports on the preparation of the various latex dispersions. Mean particle sizes were obtained from simple turbidity measurements, quasi-elastic light scattering, and electron micrographs. The behavior of the particles in the centrifugal force field is a simple tool for detecting aggregation tendencies that are not directly related to salt stability. The BET-surface area agrees with the area calculated from the mean particle size when a sharp boundary and smooth surface is developed between the particle and the surrounding medium. In the case of particles with extended boundary regions (core/shell particles or particles with hairy envelopes), film formation reduces the specific surface area. Removal of soluble oligomers and polymers from the boundary region during subsequent treatments (purification and centrifugation before freeze-drying) can increase the surface area considerably.

    Intercalation and exchange reactions of clay minerals and non-clay layer compounds (1991)
    Springer
    Colloid & polymer science 269 (1991), S. 1198-1211 
    Details
    ISSN: 1435-1536
    Keywords: Alkylammonium lions ; cation exchange ; clay minerals ; intercalation ; layered materials ; silicic acids ; surfactants

    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Presently, a large variety of layered materials are synthesized that are able to intercalate neutral guest molecules or to exchange inorganic and organic ions for interlayer ions. Several of these materials are also found as minerals. The intracrystalline reactivity of a few selected compounds will be described and compared to clay minerals: - intercalation into crystalline silicic acids; - reactions of phosphates, arsenates, and sulfates; - reactions of titanates, niobates, and molybdates with long chain alkylammonium ions, and - anion exchange properties of double hydroxides. A general conclusion is that the non-clay minerals in many ways behave like clay minerals, but there is no doubt that the reactivity of clay minerals and the variety of their reactions cannot be exceeded by any other material.

    Displacement processes on hydrophilic/hydrophobic surfaces in methanol-water mixtures (1992)
    Springer
    Colloid & polymer science 270 (1992), S. 1027-1034 
    Details
    ISSN: 1435-1536
    Keywords: Solid liquid interface ; multilayer ; adsorption ; enthalpy of displacement ; layer silicate
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract The adsorption from methanol/water and the enthalpy of displacement of methanol by water were studied on K-60 silica gel, on graphitized PRINTEX-80, and onn-alkylammonium vermiculites. The adsorption between the hydrophobized silicate layers was followed by x-ray measurements. The excess isotherms of alkylammonium vermiculites in methanol/water exhibit two maxima corresponding to the two steps of the individual isotherm. The equilibrium constant of the exchange of water by methanol is calculated. For calculating the adsorption capacities and molar adsorption potentials, a new equation is proposed which combines the adsorption excess quantities with free energy and enthalpy functions.
