    Phase structure of polyetherpolyol-4,4′-diphenylmethane diisocyanate-based reaction injection molded (RIM) polyurethanesThis paper was presented in part at the annual meeting of the Society of Polymer Science in Japan in 1981 (1986)

    Notes: A series of polyetherpolyol-4,4/-diphenylmethane diisocyanate based polyurethanes were prepared by reaction injection molding (RIM). The degree of phase separation and morphology, which govern the mechanical properties, was investigated by X-ray scattering, dynamic mechanical spectroscopy, and electron microscopy. The phase reversion occurred at just a 70 weight percent concentration of the based reagent. The degree of phase separation increased with the molecular weight of polypropyleneglycol and decreased with the ethyleneoxide capping content. Morphology was influenced by injection rates.

    Absorption of sulfur dioxide into aqueous double slurries containing limestone and magnesium hydroxide (1983)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 29 (1983), S. 60-65

    Notes: The absorption of dilute SO2 into aqueous double slurries containing CaCO3 and Mg(OH)2 was carried out using a stirred tank with a plane gas-liquid interface. The absorption rate increased and finally reached that under the completely gas-film controlled conditions as the absorption process proceeded. The desulfurization process using the double slurry was formulated by a two-reaction-plane model in which there are no particles suspended in-between the interface and the primary reaction plane. It was suggested from comparison of the experimental absorption rates with the theoretical predictions that 40 to 60% of the absorbed sulfur dioxide may be present as an effective magnesium sulfite ion pair.

    New simultaneous modular method for calculating multistage multicomponent separation processes (1983)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 29 (1983), S. 538-544 
    Details
    ISSN: 0001-1541

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A new flexible method has been developed for modelling multistage multicomponent separation processes. The method is based on the simultaneous modular approach and can be referred to as a quasilinear two-level modelling. The network is solved within each iteration as a linear one, and after each network solution the split streams are updated modularly using nonlinear submodels. The method is suited for modelling the most important separation processes with arbitrary structure and permits to use different models for the subunits or processing units. Illustrative examples and computational results are presented showing the efficiency, flexibility and capability of the method.

    Elastic scattering and vibrational excitation of CO2 by 4, 10, 20 and 50 eV electrons (1980)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: Elastic and vibrationally inelastic differential, integral and momentum-transfer cross sections for electrons scattered by CO2 molecules are reported at 4, 10, 20 and 50 eV impact energies. The elastic cross sections are placed on an absolute scale by means of a relative flow technique. The inelastic cross sections are normalised to the elastic ones by using the inelastic to elastic intensity ratios. Data are reported for up to ten features in the 0.0 to 0.4 eV energy-loss region.

    Electron energy-loss spectra in molecular fluorine (1979)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: Electron energy-loss spectra in molecular fluorine, for energy losses from 0 to 17.0 eV, have been taken at incident electron energies of 30, 50, and 90 eV and scattering angles from 5 to 140 deg. Features in the spectra above 11.5 eV energy loss agree well with the assignments recently made from optical spectroscopy. Excitations of many of the eleven repulsive valence excited electronic states are observed and their location correlates reasonably well with recent theoretical results. Several of these excitations have been observed for the first time and four features, for which there are no identifications, appear in the spectra.
