We describe a design methodology for synthesizing cubic-phase optical elements using two-dimensional subwavelength microstructures. We combined a numerical and experimental approach to demonstrate that by spatially varying the geometric properties of binary subwavelength gratings it is possible to produce a diffractiv…
This work reports the effect of the heater electrode of a bilayer structure on phase-change memory (PCM) devices. The large amount of Joule heat generated from the high-resistive single-layer heater degraded the PCM device, whereas the bilayer heater composed of two kinds of different materials improved the device rel…
This is a study on the field emission (FE) from carbon submicron-tube multiwall covered with carbon nanotubes (MWCNTs), which forms a dendrite structure as a field-emitter array, by chemical vapor deposition method. To improve the FE luminescence uniformity, the bamboo carbon submicron tubes are grown on a reactive cu…
Systems of silty sand-water and clayey rock-water were simulated under open-system conditions with respect to CO 2 and oxygen at 25°C. It was shown that the dawsonite(+ quartz)+kaolinite assemblage at the Zaozernyi deposit was formed by interaction of terrigenous sediments with chloride-sodium solutions containing NaC…

V 2 O 5 thin films were prepared by pulsed laser deposition (PLD). Ag-doped V 2 O 5 thin films were prepared by the reaction between V 2 O 5 thin films and 1 M AgNO 3 solution for 3 min. Photochromism and photoelectrochromism in V 2 O 5 and Ag-doped V 2 O 5 thin films were investigated. Absorption spectra measurement…
Here, we theoretically predict antiaromatic double-decked compounds [DMB(6)](q-) (D = B(6)(2-), Cp(-); M = Li, Na, K, Be, Mg, Ca) as well as the triple-decked sandwich-like species. Being energetically higher than the fusion isomers, the homo-decked assembly species [B(6)MB(6)](q-) without and with counterions are les…
The doping effects of Al2O3 on SiO2 (α-cristobalite) have been studied by first principles calculations, with emphasis on the structural, electronic and optical properties. Compared to pure SiO2 crystal, the electronic density of states (DOS) of the Al2O3 doped SiO2 show significant changes. The electron energy states…
There are some fatigue damage estimation methods of an austenitic stainless steel that uses martensitic transformation. For instance, those are the remanent magnetization method, the excitation method, and so on. Those two methods are researched also in our laboratory now. In the remanent magnetization method, it is w…

Poly(butylene adipate-co-terphthalate) (PBAT) is a biodegradable polymer with high ultimate elongation but low modulus. This paper demonstrates that the addition of nano-sized clay can improve the modulus without significantly decreasing the tensile strength and biodegradability of the PBAT , while offering enhanced b…
The interior design of motor vehicles depends mostly on the appearance and properties of fabric with prevailing woven articles. When upholstering motor vehicle seats and interiors fabrics mostly constitute the exterior part of these interiors, as so-colled original covers. These fabrics belong to the group of technica…
A theoretical model is introduced to derive the ME voltage coefficients of bilayer in free state according to the constitutive equations of magnetostrictive and piezoelectric phases. Using this model, the ME voltage coefficients of La07Sr03MnO3(LSMO)-PZT and Tb1-xDyxFe2-y (TDF)-PZT bilayers have been calculated and…
The work is devoted to increase of foundry properties of secondary silumins. The influence of a chip contents in charge, quantities of iron in an alloy and the modifier used for processing of liquid metal, on fluidity, linear shrinkage, crack resistance and a porosity number of silumin AlSi9Cu2 is considered.
This study investigated the effects of nano TiO 2 in self-cleaning leathers. Nano TiO 2 was applied as a top coat to white goat leathers at 25%, 50%, 75% and 100% ratios, based on the amount of lacquer emulsion. To observe the self cleaning effect, the leather samples to which nano TiO 2 had been applied and control s…
Well aligned ZnO nanorod arrays on Si substrate previously coated with a thin buffer layer of ZnO seeds via radio-frequency magnetron sputtering, which were synthesized by the aqueous solution method. The sample was characterized by scanning electron microscopy, X-ray diffraction, high-resolution transmission electron…
The mathematical models of the strength of fancy yarns with continuous effects (plied twoand three-component yarns and loop yarn) were developed on the basis of the mechanical rules, phenomena occurring between the staple fibres in the component yarns and the final structure of fancy yarns. Three types of distribution…
Under DC current biasing the additional losses of power transformer increase significantly, as a result the loss of iron core can not be identified from the no-load loss correctly. It is necessary to establish an accurate model of the iron core to evaluate its possible overheating problem. Based on the Jiles-Atherton…
Using 1,4-butanediol as initiator,boron trifluoride etherate as catalyst and CH2Cl2 as solvent,poly(3-nitratomethyl-3-methyl oxetane)(PNIMMO) was prepared by 3-nitratomethyl-3-methyloxetane via cationic ring-opening polymerization.The effect of molar ratio for catalyst and initiator,reaction temperature and the droppi…
In order to explore the relationship between parameters of UHF signals and discharge magnitude of pulse current in partial discharge(PD)detection in oil-paper insulating power equipment,the differences of principle between current pulse measurement and UHF measurement in PD is introduced.Four typical PD models are con…
