The paper is devoted to studying the effect of the specific surface area (SSA) of SiO2nanopowders (3 wt.%) added to BaSO4powders of a micron size on grain size distribution and diffuse reflectance spectra (ρλ) within the UV, visible, and near IR regions. Additionally, the authors have examined the spectra alteration (Δρλ) after irradiating with electrons (E=30 KeV). It has been established that mere mixing of the powders at a low concentration of nanoparticles leads to the post-irradiation decrease in the reflective power and to the subsequent increase in the reflectance coefficient stability.

The preparation of some new complexes of cobalt and 2-pyridinaldoxime are described. Magnetic and conductometric measurements are reported along with their infrared, ultraviolet and visible, and diffuse reflectance spectra. The possible structure of one of the complexes is postulated.
