    Notes: Transmission Mössbauer spectroscopy has been used to obtain information on structural and chemical conversions in the surface layers during preparation of finely dispersed iron powders by high-temperature reduction of α-FeOOH. The two-stage technique of preparing 56Fe-based particles with an 57Fe surface layer makes it possible to obtain high-quality Mössbauer spectra from surface layers 4-5 nm thick on different reduction stages. The investigations performed allowed us to consider the possibility of studying physicochemical processes in ultrathin surface layers by means of transmission Mössbauer spectroscopy. © 1998 John Wiley & Sons, Ltd.

    Notes: The process of modifying the surface of particles of dispersed polymer fillers, using tensides, has been studied. The main principles were established with regard to the effect of modification of titanium dioxide and kaolin on the structure formation in solutions and block formations of chlorinated poly(vinyl chloride) resin and rubber, depending on the nature and concentration of the modifier. The decisive part played by chemisorption of the tenside in lyophilization (water-repellency treatment) of the surface of the filler and its activation, as a structure former, has been elucidated.
