    Notes: Abstract There has been a considerable improvement in the knowledge of stratospheric positive ion chemistry during the last decade. Results of several in-situ measurements of ion composition have been reported. Total ion density has also been measured with greater accuracy. In this work, theoretical study has been made to reproduce the main features of the above observations. Difficulties encountered in such studies are discussed. Finally models of total ion density and ion composition are given.

    Description / Table of Contents: Abstract РФЭС спектры LaCoO3 были сняты перед и после обработки in situ окисью углерода при комнатной температуре и 200°C. Доказано, что газовая CO реагирует с хемосорбированным кислородом, давая CO2.
    Notes: Abstract XPS spectra of LaCoO3 have been studied before and after in situ treatment with carbon monoxide at room temperature and at 470 K. It has been concluded that gaseous CO reacts with chemisorbed oxygen to form CO2.

    Carbon monoxide oxidation on cobaltites of the lanthanides: Effect of A-site substitution (1987)

    Description / Table of Contents: Abstract Каталитическое окисление CO исследовано на Nd1−xBaxCoO3 и LnCoO3 (Ln=La, Sm, Nd, Dy). Каталитическую активность сравнивали с изменением х, кхслородных дефектов и со структурнями изменениями. Найдено, что соединехия с кубической структурой дают максимальную активность, которая уменьшается в направлении от кубической структуры. Это объясняют лучшей делокализацией d-электронов кобальта кубических соединений.
    Notes: Abstract Catalytic oxidation of CO has been studied on Nd1−xBaxCoO3 and LnCoO3 (Ln=La, Sm, Nd, Dy). Catalytic activity was compared with changing x, oxygen defects and structural changes. It has been found that compounds with cubic structure show maximum activity, which decreases with deviation from cubic structure. This has been explained as due to better delocalization of the d-electrons of cobalt in the cubic compounds.
