Manganese gallium oxide (MnGa 2 O 4 ) one-dimensional nanostructures were synthesized by the thermal evaporation of MnCl 2 /Ga/Zn. The single-crystalline spinel-structured MnGa 2 O 4 nanowires are preferentially grown in the [111] direction. In contrast, the Zn (10%)-doped MnGa 2 O 4 nanostructures adopt zigzag struct…

The structure and phase composition of La0.65Sr0.35Mn1 − x − y NixTiyO3 manganites (0 ≤ x ≤ 0.3; 0 ≤ x + y ≤ 0.3) obtained by solid-state reactions in air are studied by x-ray diffraction. All the samples are single-phase materials and have an orthorhombic or pseudocubic structure, depending on the chemical compositio…
Abstract A physical self-assembly process based on ac-dielectrophoretic deposition of single-walled carbon nanotubes between metallic electrodes and subsequent gate-voltage controlled elimination of the metallic nanotubes is reported that allows fabrication of multi-tube carbon nanotube field-effect transistors with e…
According to the request of the sensitive wave band of 0.38 mum-0.52 mum of the bionic micro-nano navigation sensor, the paper designed a wire-grid polarizer which can be effectively used in the region of blue-violet light spectrum based on rigorous coupled-wave theory. The difference between the designed wire-grid po…
The paper addresses the influence of diamond-containing mixture and detonation nanodiamonds on the physical-mechanical and physical-chemical properties of polymer composites based on foamed polyurethane, frost-resistant butadiene-nitrile rubbers, polycarbonates, rubbers resistant to explosive decompression, and gas pl…
The anisotropic diffusion in coiled pore systems of SBA-3-type microparticles has been studied by the release of guest molecules. The diffusion turns out as an example of the influence of hierarchical structuring on physical properties. Two modes of diffusion, associated with transport along and across the mesopores,…
The band structures of pure semiconductors CdGeAs2 and CuGaTe2, as well as magnetic semiconductors Cd1 − x Mn x GeAs2 and Cu1 − x Mn x GaTe2 (x = 0.0625), have been calculated by the density functional theory method. In both compounds, the Mn3d orbitals form a narrow band near the Fermi level. In the case of Cd1 − x M…
The conditions for the formation of CuInTe 2 nanoparticles in silicate matrices are studied by means of optical spectroscopy and electron microscopy. The formation of the particles of the semiconductor phase in size from 15 to 30 nm occurs at the stage of cooling of the melt and depends essentially on the composition…
Siliceous spicules of Baikal freshwater sponge Lubomirskia baicalensis contain several proteins, including silicateins. Analysis of a L. baicalensis cDNA library revealed four different mRNAs coding for proteins related to marine sponge silicatein α (α1, α2, α3, and α4). The intron-exon structure was determined forthe…
The effects of chirality and diameter on the electron transport properties of semiconducting, single wall, carbon nanotubes are explored by the Ensemble Monte Carlo method and an iterative solution of the Boltzmann’s transport equation. The results show that the effect of chirality is significant for small diameter tu…
Abstract Summary: A wide range of hyperbranched polymers (HBP) was synthesized and investigated as additives in cationic photopolymerization of epoxy systems. The HBP were inserted into the polymeric network either by a copolymerization or through a chain transfer reaction involving the phenolic hydroxyl groups. By va…

Various rare-earth-doped α-SiAlON powders with high purity were prepared to study mechanical and optical properties of SiAlON-based functional materials in connection with ionic radius and electronic structure of rare-earth elements. Single phase rare-earth-doped α-SiAlON powders were obtained at a temperature as low…
Abstract Summary: The structure‐directing effect of two amphiphilic dopants on the nucleation and growth mechanism during the formation of micro/ nanostructured polyaniline (PANI) and polyaniline‐clay nanocomposites (PANICNs) is described. PANIs and PANICNs were prepared by in‐situ intercalative emulsion polymerizatio…
The presented results of our galvanoluminescence (GL) measurements of oxide films formed by anodization of high purity aluminum samples annealed at 550 °C in inorganic electrolytes show that the sudden rise in the formation of γ alumina crystalline regions is strongly related to the appearance of GL. We have recorded…
Nanofibers have a large potential in air filtration applications, so this paper explores the performance of electrospun nanofiber membrane compared to traditional filtration fabrics. Poly (ethylene oxide) (PEO) and Polyvinyl Alcohol (PVA) were electrospun into nanofibrous membranes and analyzed their filtration attrib…
