“…We believe that the effect can take place due to the photoinduced ordering of MR molecules under the action of non-polarized light in such a way that their transition dipole moments become parallel to the direction of light propagation. Similar effect of the photo-induced molecular ordering was found in some photochemically stable azo dyes in polymer matrix [35], amorphous film of azo dyes formed by vacuum evaporation [36] or spincoating [37] and Langmuir-Blodgett films [38]. Liquid Crystals and their Application.…”

A photo-induced anisotropy (PIA) of Methyl Red (MR) azo dye embedded in PMMA polymer solid films was investigated by studying dichroic spectra and photo-induced birefringence. The reversible PIA of MR dye was measured in situ during photoactive irradiation process. Photoinduced order increases with the rise of exposure power. It is shown that PIA dark relaxation slows down at higher exposure energy. The MR rotational diffusion was evaluated at different exposure modes. These data are useful for the characterization of Methyl Red azo dye as a liquid crystal photo-aligning material.

The composite scintillators from inorganic scintillators and organic phosphors provide unique combination of high light yield and nanosecond temporal resolution. Preparation of microfibers of these composites by means of centrifugation resulted in forming of axial nanosplitting and transverse micromodulation of their structure and optical properties, These modulations result in essential improvement of scintillation parameters of the composite providing the development of relatively simple and cheap X-Ray microscope. Ball rolling of inorganic solids provides superfast introduction of organic and inorganic components into subsurface layers for the special modifications of their properties. The superfast introduction is explained by propagation of nanocracks involving necessary dopants into the solid.

The recovery of copper by iron in copper sulfate aqueous solutions was studies as a function of the external magnetic field and morphologies of iron containing steel samples. Essential retardation of the recovery by the magnetic field was found as well as decrease of iron sulfate solubility in water induced by the field. The retardation is explained by the active participation of inter-domain walls in the recovery and decreasing of their length in the magnetic field. When steel filings were used for the recovery instead of the volume samples the magnetic retardation was not notices. Applications of these results are developed for new methods of lithography of microschemes and restoration of electrical contact wires.
