Based on the analysis of the K 2 O-P 2 O 5 -D 2 O solubility phase diagram, the optimum conditions of KD 2 PO 4 crystallization—the compositions of mother solutions and the temperature range of crystallization—in the KH 2 PO 4 -D 2 O system have been determined. The technique of K(D x H 1 − x ) 2 PO 4 growth is develo…
We have investigated an effect of vanadium or aluminum into titanium alloys on the formation of Kirkendall voids in titanium region in diffusion bonds between titanium and molybdenum. The influence of bonding conditions on the joint stregnth has been also investigated. The bondings were performed under bonding tempera…
アミロペクチンからなるワキシコーンスターチを用いてアクリル酸デンプンを合成し，さらに架橋することによりデンプンの機能化を検討した．高置換度のアクリル酸デンプンは，ピリジン中でデンプンにアクリル酸無水物を作用させることによって得られた．高置換度アクリル酸デンプンを用いた重合では，分枝構造による立体障害などによって架橋ポリマーを得ることができなかったが，高置換度アクリル酸デンプンとアクリル酸とを共重合すると，架橋反応物が得られた．この共重合体の架橋部分は重合度の低いアクリル酸重合体であり，生分解性ポリマーの原料として用いることができると思われる．一方，低置換度アクリル酸デンプンとアクリル酸との共重合では，架橋デンプンは得られなかった．

A small amount of LaAlO3 added to a La2O3:3TiO2 starting oxide mixture stabilizes the A-deficient La2/3TiO3 perovskite structure. According to XRD and microstructural investigations of samples prepared in the ternary system at 1400?C, only the solid solution along the La2/3TiO3-LaAlO3 tie-line extends from at least 4…
The functional properties of liquid crystal (LC) thin films are correlated to their structure and microstructure. Moreover, not only phase and order of LC are important parameters influencing these properties, but also thickness, density, and roughness of the film. In this paper a study of multilayer systems LC/ITO/gl…
The crystal structure and the dielectric properties of the antiferroelectric solid solution of (1 m x )Pb(Yb 1/2 Nb 1/2 )O 3 m x Ba(Yb 1/2 Nb 1/2 )O 3 (Pb 1 m x Ba x YN) (0 h x h 0.30) have been studied. The crystal structure is shown to become pseudocubic from the PYN's orthorhombic structure on solutionizing for x >…
The interest in ultra-high-purity (UHP) metals and alloys (including single crystals and bicrystals) in studying damage mechanisms is presented through three practical cases of environment or precipitation-induced damages in nuclear power plants. First, stress corrosion cracking mechanisms are assessed by direct measu…
We carried out a complex spectroscopic study of CaTiO 3 . The dielectric, submillimeter, infrared and Raman measurements in broad spectral and temperatures ranges were performed. We found in all experiments similar behavior of the soft mode, whose frequency varies from 110 to 70 cm m 1 on cooling from room temperature…
Comparative lifetime analysis of the ITER divertor Plasma Facing Components (PFCs) - Carbon Fiber Composite (CFC) monoblock with a cooling tube made from CuCrZr has been performed. The aim of this analysis was to evaluate acceptable mechanical properties of the CuCrZr cooling tube, such as ultimate tensile strength (U…
We studied the electronic band structure of isolated and bundled single‐walled nanotubes by ab initio calculations. Curvature effects on the electronic states depend on the chirality of the nanotube; the strongest deviations from the zone‐folding approximation are found in zig‐zag tubes. Bundling of the tubes to ropes…

A theoretical method for the estimation of mechanical characteristics of polymeric structures is proposed. This method uses the statistical polymer method for modeling branched/crosslinked structures. The proposed method is utilized for the estimation of mechanical resistance and stability of microporous polymeric mat…
It's proved that a reaction exists in poor grade carbonatite and modified water glass system at ambient temperature. The reaction products are identified as hydrated calcium (magnesium) silicate by SEM, XRD and EDX and the reaction mechanism is discussed.
The corrosion of Al (99.99% in mass) in deaerated methanol with and without H2O, NaCl, and HCOOH as contaminants was investigated using immersion corrosion tests, potentiodynamic polarization tests, electrochemical impedance spectroscopy (EIS), and X-ray photoelectron spectroscopy (XPS). The content of H2O in deaerate…
Beta-cyclodextrin can act as an efficient inhibitor of the photosensitized dimerization of thymine by para-aminobenzoic acid (PABA) in aqueous solution. This can be explained by considering the formation of an inclusion complex between PABA and beta-cyclodextrin.
The adsorption characteristics were investigated with differently sized agglomerates of zeolite particles for moving-bed applications. As a result, the saturation amount of NO gas adsorbed on the agglomerates was almost the same as that of the primary particles, and thus the negligible influence of binder was confirme…
Two new homologous series of 4-cyano- and 4-nitro-N-(4-alkoxysalicylidene) anilines were synthesized. The phase transitions of these homologues were determined by using a differential scanning calorimeter and an ordinary polarizing microscope. It is shown that all the homologues having a terminal cyano group exhibit a…
Flux-cored are welding (FCAW) has increased recently because of high welding efficiency. However, a small amount of bismuth in the weld metals was a residue from the flux component that was added for improving slag detachability. The effect of small amount of bismuth in austenitic stainless steel weld metal on corrosi…
Three-dimensional simulations of bidisperse bubble swarms rising in a liquid have been carried out. This article describes the microstructure of a swarm of mostly spherical bubbles representing 6% void fraction. The swarm consists of an equal number of large and small bubbles with volume ratio 2. While the behavior of…
