Photo-oxidation (in the presence of eosin Y as a sensitizer) of isohemagglutinating sera destroyed their agglutinating activity gradually, but did not seem to convert any of the agglutinins studied into inhibiting ("incomplete" or "blocking") antibody.

Differential activity of Frizzled in the R3/R4 photo-receptors of Drosophila regulates the orientation of ommatidia. New evidence suggests that the cadherins Dachsous and Fat act upstream of Frizzled in this process.

Mn doped ZnO nanocomposite thin film coated on glass by a simple spin-coating method was used to degrade an azo textile dye from aqueous environment. Mn doped ZnO nanocomposite thin film was characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The photo-reduction activity of photocatalyst was evaluated using an azo textile dye as organic contaminant irradiat...

Porous nanocomposites based on PrFeO3-TiO2 were synthesized using the glycine-nitrate combustion method with different values of mass content TiO2 (0–7.5 %) and subsequent heat treatment in air. The results X-ray phase analysis Raman spectroscopy confirmed presence ultradispersed TiO2, structurally close to that anatase. morphology, specific surface area, porous structure obtained powders chara...

A composite material based on polyvinylidene fluoride (PVDF) nanofibers modified with cetyltrimethylammonium bromide (CTAB) was synthesized by coaxial electrospinning. The morphology and structure of the were studied SEM, FTIR spectroscopy, X-ray diffraction analysis, XPS, piezo-photo- piezo-photocatalytic activity during decomposition organic dye Methylene blue (MB) studied. It is shown that a...

Background & Aims of the Study: Phenolic compounds have been extensively used in industries for applications such as petrochemical, oil refineries, papers, plastics, steel, pharmaceuticals, textiles, coal conversion, and so on. Specified amounts of Phenolic compounds are lost in the process of their manufacturing and utilization and often cause environmental pollution problems....

Nickel-manganese oxides with variable Ni : Mn ratios, synthesised from heterobimetallic single-source precursors, turned out to be efficient water oxidation catalysts. They were subjected to oxidant-driven, photo- and electro-catalytic water oxidation showing superior activity and remarkable stability. In addition, a structure-activity relation could be established.

The development of the photo-catalysis field is limited by a deficient quantitative assessment photo-activity. interplay between mass and momentum transport together with radiative transfer phenomena taking place at any photo-catalytic reaction or process makes complex such assessment. To reach this goal, review studies measurement, meaning, analysis three types observables. first family observ...
