Abstract Ag 9 I 3 (SeO 4 ) 2 (IO 3 ) 2 was obtained for the first time by reacting a stoichiometric mixture of Ag 2 O, AgI and SeO 2 at elevated oxygen pressure (255 MPa) and at a temperature of 500 °C. Ag 9 I 3 (SeO 4 ) 2 (IO 3 ) 2 was characterized by X‐ray powder diffraction, differential scanning calorimetry, impe…
Abstract The new class of quasi‐2D superlattices based on graphene with periodically adsorbed hydrogen pairs was proposed. The ab initio DFT method was used for optimization of the atomic geometry and electronic structure of proposed structures. It was found that the superlattices band gap decreases nonmonotonically w…
In electron energy-loss spectroscopy, the excitation of low energy transitions, such as the crystal-field transitions in $3d$ transition-metal oxides, takes place via two scattering mechanism, namely, direct scattering and exchange scattering. The angular cross sections of both scattering mechanisms have been investig…
The main attempt of this investigation is to establish a model for evaluating internal geometry of woven fabric. A new concept about packing density of yarns inside of fabric is putted in forward and then internal geometry of fabric before deformation is predicted by common data of a fabric. A numerical analysis has b…
Heterotrimeric arylboroxines can be favorably formed by designing one of the arylboronic acid monomers to contain a pendant Lewis base. Using density functional theory (B3LYP//6-311+G*) calculations including Poisson-Boltzmann implicit solvent, we found that AB2 trimeric arylboroxines were thermodynamically favored ov…
The thermal conductivity of AlN ceramics with different amounts of Y 2 O 3 as sintering additive has been calculated at low, intermediate and high temperatures by applying the Callaway theory and using a detailed account of three-phonon scattering processes. By making a quantitative analysis of the results, it is foun…
An experimental evidence of the effects of iron on the magnetic and local electronic properties of ${\text{TiO}}_{2}$ single crystals is provided. When ferromagnetic rutile ${\text{TiO}}_{2}$ single crystals are doped with Fe ions, an enhancement of the saturation magnetic moment is observed, along with a transfer of…
The temperature-induced phase transition between the chiral smectic phases, antiferroelectric (smectic-C(A)*) and ferroelectric (smectic-C*), is found to occur through solitary wave propagation. We measure the free energy, which shows a double well shape in the entire SmC(A)* temperature range and the global minimum i…
The anhydrous crystalline phase of chloroquine bis-(dihydrogen phosphate) is obtained by dehydration of the corresponding hydrate phase, but in common with many solid-state dehydration processes, the product is obtained as a polycrystalline powder, thus limiting the opportunity to carry out structural characterization…
Systematic research works were carried out to clarify the effects of weave density, yarn twist, and yarn count on fabric handle of polyester fabrics made for the purpose, and quantitative influence was clearly shown. “Kosh” and “hari” increase with weft yarn density and “shinayakasa” and “shari” decrease with the dens…
Transformation and distribution of sulfur compounds in fossil fuel thermal processing depends on the bonding forms of sulfur in the specific feed-stock, thermal processing conditions and the technology used. This paper is focused on oil shale semicoking in a pilot-scale solid heat carrier retort (Galoter process) wher…
The molecular structures of chloro(phthalocyaninato)aluminum(III) (ClPcAl) and chloro(phthalocyaninato)gallium(III) (ClPcGa) have been determined by using the gas electron diffraction (GED) method and augmented by quantum chemical calculations. The molecular structures of fluoro(phthalocyaninato)aluminum(III) (FPcAl),…
Abstract A single‐source approach using mild temperatures was applied to prepare morphological well‐defined and coupled TiO 2 /metal–sulfide nanocomposites. Metal N ‐alkyldithiocarbamates were used as the precursors to the metal–sulfide nanophases and, in particular, Ag 2 S nanostructures were investigated in more det…

Density functional theory has been applied to a series of unsubstituted planar metalloporphyrins (MPs) to elucidate how geometry and frequencies correlate with the metal-nitrogen distance, referred to as the core size. Different transition metals can invoke expansion or contraction of the porphyrin core due to electro…
Abstract In this paper we discuss the environmental effects on the radial breathing mode (RBM) spectra of Single Wall Carbon Nanotubes (SWNTs). We have shown that the environmental effect on the radial breathing mode frequencies can be explained by Van‐der‐Waals interactions. We here explore these interactions concern…
This paper reports the transmission characteristics, i.e. air permeability, thermal conductivity and moisture vapour transmission, of needle-punched non-woven fabrics made from shrinkable and non-shrinkable acrylic blends. The basic idea of this work is to explore the possibility of structural changes in needle-punche…
As deep ultra-violet (DUV) wavelength optical systems progress towards higher numerical aperture (NA), at least some of the lens surfaces in the system approach almost complete hemispherical shape and some of the lens surfaces have very high angle of incidence (AOI) requirements. The antireflection (AR) coating design…

Abstract Thin films of functionalized carbon nanotubes were deposited on silicon chips by drop‐coating and inkjet printing. These sensors were exposed to 50 ppm N 2 O, CO, H 2 S and H 2 O vapour in dry synthetic air. We have found relatively small changes in the electrical resistance of the films exposed to the differ…
