Migrant Workers from Central Asia in Moscow: Adaptation Issues
The article is based on the results of the survey of migrant workers from Central Asia in Moscow and Moscow region. One of the key issues of the study was the degree of adaptation of migrants to life in the capital. The article discusses the issue both from the point of view of experts on labor migration and of the migrants themselves
Influence of modifying additives on formation of supported copper nanoparticles
The influence of modifying additives of Ce, Zr, La and Cs
oxides on changes of electronic state of supported copper during the
catalytic reaction of butane complete oxidation has been studied by the
methods of IR-spectroscopy of adsorbed CO, XPS, EXAFS and XRD. The modifying
additions of cerium and zirconium oxides stabilize the ionic state of
copper, while lanthanum and cesium oxides decrease the effective charge of
copper ions. The observed effects are caused by variation in metal
dispersivity in the modified samples and by electron donor-acceptor
interaction of the surface atoms and ions of copper with the modifier
