Epitaxial BaTiO3 thin films grown on MgO-buffered R-plane-cut Al2O3 substrates show a non-uniform distribution of planar defects. Transmission electron microscopy allows the determination of the distributions of planar defects with respect to the Al2O3 substrate. The BaTiO3 film, the MgO buffer and the Al2O3 substrate…

Abstract Polysulphide sealants are now widely used to ensure the integrity of fuel tanks on both civil and military aircraft. The consequences of failure of such sealants are severe both in terms of the length of time that the aircraft will be removed from service and the nature of the remedial work that must be carri…
A new class of polyphenylated phthalocyanine derivatives containing near-planar aromatic rings attached to the phthalocyanine core has been synthesized. The aromatic rings contributed to a significant red shift of the Q-band absorption. Linear optical and electrochemical properties of these derivatives are described.
Abstract Thin Co/ZrO 2 and Co/S‐ZrO 2 catalytic films for hydrocarbon‐selective catalytic reduction (HC‐SCR) of NO x were prepared and characterized by means of XPS, SEM and scanning Auger microscopy (SAM). Zirconia was deposited on a fibrous inconel support (Bekaert) by the sol–gel method. Cobalt was deposited on pur…
The structure and thermo emf of nanotubular and fractal carbon layers deposited from an electric discharge plasma were studied. The thermo emf of such nanotubular and fractal deposits is almost tenfold higher as compared to that of polycrystalline carbon, which is explained by the nanostructural state of carbon in the…

Ladder-knit fancy yams are produced using a range of take-up ratios and component yams on a knitting machine that produces fancy yams. The effect of the properties of the component yarns on the final count, tenacity at break, and appearance of ladder-knit fancy yams is studied, and an expression is derived to determin…
Environmentally assisted cracking involves synergistic interactions between corrosion and deformation processes. This study focused on providing insight into the influence of the environment on the time-dependent deformation behavior of an ultra-high-purity Ni-16Cr-9Fe alloy in argon, dissociated hydrogen, and water e…

Abstract To investigate the misorientation dependence of fracture behavior and Sb segregation level for different [001] symmetric tilt boundaries in Cu–2.0 mass% Sb alloy bicrystals, tensile tests at several temperatures from 77 to 743 K and energy-dispersed X-ray spectroscopy analyses were performed. The degree of em…
The paper describes the electric field behavior near a contact point in various arrangements with a zero contact angle when surface conductivity is present on a solid surface. Electric field distributions are calculated for arrangements with three contact conditions: point, line, and surface contact. We focus on the e…
To detect subtle depletion of nonexchangeable K occurring in the rhizosphere, extraction with a much weaker acid solution (0.01 m HCl) than that conventionally used (1 m HNO3, 1 m HCl) was attempted. Soils sampled from the rhizoboxes in which maize (Zea mays L.) had been growing for 17 d was sequentially extracted, fi…

Abstract We have explored the possibility of obtaining information about the surface nanostructure (i.e., how a given phase of material is distributed near to the surface region) from the analysis of loss plasmons that appear in the lower kinetic energy side of photoelectron and Auger peaks. First, we show an example…
The present article reviews the feasibility of electrochemical noise (ECN) measurements as a corrosion probe for monitoring corrosion changes on stainless steel 304L (UNS 30403). Controlled tests for ECN and weight lossmeasurements were conducted in 10% NaCI solution for stainless steel 304L (UNS 30403). Corrosion beh…
Abstract The oxidation of (Pb,Ge)Te crystal surfaces at ambient temperature and humidity was studied by means of XPS in a time range from minutes to months. Vacuum‐cleaved crystal was used for the experiment. It was found that Ge in a PbTe lattice occupies two different positions. At one of them, donor behaviour is re…
Temperature dependences of the dielectric permittivity of betaine phosphite crystals are studied both without and under application of an electric bias. It is shown that, in view of the fact that the high-temperature improper ferroelastic (antiferrodistorsive) phase transition at T c 1 =355 K is nearly tricritical, th…

The crystal structure of priceite, data and refined to Rwp = 0.042 and Rp = 0.030 using the Rietveld method. The monoclinic structure was refined in space group P21/c, a 11.623(1), b 6.976(1), c 12.350(1) Å, β 110.70(1)°, V936.72(1) Å3, Z = 4. The structure consists of infinite chains of pairs of borate rings that ext…
