    Notes: [Auszug] Polystyrene latices may be grown in the absence of emulsi-fier1,2 (Table 1); however, the ultimate size of the latex produced is limited. In an effort to obtain larger particles, using an emulsifier-free technique, we used a two-stage process whereby a latex of selected size was utilised as the ...

    Notes: [Auszug] Pieces of lung, fixed in 2% glutaraldehyde and 1 % osmium tetroxide, were further fixed and stained in a mixture of 10 vol M/40 lead nitrate and 10.5 vol M/60 potassium ferricyanide solutions. They were embedded for electron microscopy in 'Araldite' with acetone as dehydrator and thinner and a ...

    Notes: Résumé On a étudié le poumon au microscope électronique par des méthodes speciales pour ménager les inclusions lamellaries osmiophiliques. On a conclu que la substance tensioactive n'est pas produite par la membrane superficielle des cellules alvéolaires, mais par les inclusions lamellaires des cellules du second type.

    Notes: Résumé Les inclusions lamellaires des cellules du second type du poumon sont la source de la substance tensioactive. Chez l'homme et les singes de l'ancient et du nouveau monde, ces inclusions sont de forme concentrique et peuvent provenir du réticulum endoplasmique. Chez d'autres mammifères, y compris un lémurien, elles ont, pour la plupart, des barres rectilignes ou arguées et proviennent des corps multivesiculaires.

    Study of the anomalous particles formed during the surfactant-free emulsion polymerization of styrene (1977)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 15 (1977), S. 2311-2319

    Notes: The presence of anomalous regions within polystyrene latex particles prepared in the absence of added emulsifier has been investigated. It appears that they arise through loss of monomer from particles consisting of a discrete monomer-rich region surrounded by a polymer shell. It is likely that in most cases, monomer is lost from the region on evacuation prior to electron microscope examination, although there is some evidence from γ-irradiated samples (prior to electron microscopy) that loss of monomer can also occur during storage and/or dilution of the sample. Scanning electron microscopy and carbon replication techniques have been used to determine the shapes of the voids. Gas adsorption studies and carbon replication have also served to illustrate that the presence of the regions was not due to electron-beam damage. The presence of extrusions on some samples has been attributed to incomplete loss of monomer on evacuation due to the thickness of the surrounding polymer shell.
