    Complexes of Calcium-Montmorillonite with Polymers (1960)
    [s.l.] : Nature Publishing Group
    Nature 186 (1960), S. 573-574 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] A neutral suspension of calcium-rnontmorillonite in 2 x 10"3 M calcium chloride was prepared from the 〈 2^JL fraction of Wyoming bentonite (Volelay). To an aliquot of this suspension a known amount of organic material was added as a neutral solution. The calcium chloride present ensured that ...

    Stability of Soil Crumbs (1959)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] It is now suggested that both soil organic matter and soil conditioners increase the stability of soil crumbs by linking together the principal constituents of the crumbs, the domains of orientated clay and the quartz particles. The linkages will be from the surfaces of the quartz to either the ...

    Notes: [Auszug] Up to the present, peripheral complexes have been formed only from carboxylated polymers containing no positively charged groups along the chains, such as sodium alginate, carboxymethylcellulose and poly-acrylic acid. The complexes were prepared by adding a known amount of polymer to an aliquot of ...

    Notes: [Auszug] Fig. 1. (a) Methanol on montmorillonite; (6) higher alcohols on montmorillonite To account for the observed thickness of the intercalated molecules on this hypothesis, some shortening of the van der Waals contact between the organic molecule and the clay surface is still necessary. It seemed ...

    Notes: [Auszug] Sections about 0.3 mm. thick were cut with a scalpel from the prepared flakes, placed on a glass slide and a few drops of N/30 sodium chloride added. The swelling was observed with the flake on its side, that is, with the c-axis of the crystallites perpendicular to the axis of the microscope. The ...

    Notes: [Auszug] The present work was undertaken to determine, first, whether there is a difference in the ease of dispersion of a sheared surface soil when saturated with Mg rather than Ca ions; second, to show directly, by the addition of organic compounds to the oxidized clay fraction extracted from the surface ...
