La connaissance du diagramme de phase d’un alliage est essentielle lorsqu’on élabore un matériau à la recherche de propriétés spécifiques (tenue mécanique, résistance à la chaleur, à l’oxydation, propriétés électriques, magnétiques, etc.). Il est important de connaître la stabilité des différentes phases qui peuvent s…
To evaluate a bootstrap-current-profile quickly, a simple method has been developed with a novel approximation. This results in that all of the neoclassical diffusion coefficients for the gradient become the polynominals only in variables of inverse aspect-ratio, ε, effective charge, Zeff and collisionality, ν*, in th…
Experimental investigations aimed to determine the effects of phenomena proceeding in an interface during the process of sintering the microcrystalline cBN with two types of binders i.e. fusible amorphous and glass-crystalline silicate materials were carried out. Strength of these materials is mainly bounded up with p…
The role of the alloying element has been analyzed during the oxidation process of stainless steels in the flowing lead bismuth eutectic (LBE) environment. The growth of the protective oxide film of steels has been studied at a mesoscopic scale. The influence of chrome has been studied using the developed stochastic c…
一般廃棄物最終処分コストを，全国123施設に対するアンケート調査に基づいて分析した。調査対象は立地，規模，水処理方法，被覆の有無などの条件に偏りのないよう抽出し，調査票は費目別の詳細を尋ねるものとした。イニシャルコスト，ランニングコストともに，埋立容量，水処理量，年間埋立量などに対してスケールメリットがあり，おおよそ規模の0.5～0.6乗に比例する。イニシャルコストの中では，用地取得費が大きな割合を占める場合がある。ランニングコストのうち，唯一モニタリング費は測定数が一定であり，規模に依存しない。各費用項目をすべてモデル化することで，費目間の相対的な比較が可能となった。最後に埋立コストをさまざまな条件の下で計算し，費目別の割合，お…
Managing the removal of Radioactive Materials found in public locations. In January 2006 the Environment Agency for England and Wales requested assistance in preparing a project to plan, collect and safely dispose of radium painted aluminium aircraft hatches, discovered in 3 separate business premises in the UK. These…
Real time, time-dependent density functional theory (RTTDDFT) and pseudo-atomistic Monte Carlo/molecular dynamics (PAMCMD) computational methods are used to guide the dramatic improvement in the electro-optic activity of organic materials, which are integrated with silicon nanophotonics circuitry, plasmonic circuitry…
Conductive polyaniline(PAn-_M and PAn-_O) doped with dodecylbenzene sulfonic acid(DBSA) was synthesized by using emulsion polymerization method in the presence of a constant magnetic field(0.4 T) and the absence of magnetic field, respectively.The effects of magnetic field on the microscopic morphology and orientation…
A novel structure for a composite right/left-handed (CRLH) corrugated waveguide in the millimeter-wave band is proposed. The CRLH waveguide is composed of a rectangular waveguide with tilted corrugations on its bottom broad wall. By operating above and below the cutoff frequency of the dominant mode of the rectangular…
Dynamics of nano-meter-scale liquid film on nanowire is investigated through classical molecular dynamics simulation. Liquid film of argon with 12-6 Lennard-Jones potential on the solid surface with harmonic potential breaks up into several droplets in a relaxation process to make the total surface energy smaller. Ins…
ポリアミド 6 の m-クレゾール溶液に，非溶媒としてメタノール水溶液を添加することにより，ポリアミド 6 の溶媒への溶解度を急激に下げた過飽和状態からポリアミド 6 を析出させた．ポリアミド 6 と溶媒の固-液相分離線近傍では軸晶的な構造が形成され，非溶媒組成を制御することで，軸晶の先端が扇状に広がったダンベル形状や球状の形態を有する多孔質かつ単独微粒子の形成が確認できた．この多孔質球状微粒子について，偏光光散乱(Hv 散乱)測定を実施した結果，バルク球晶と同様のバタフライパターンを示したことから，溶液から析出した球状微粒子が単独の球晶に対応する構造物であること，また小角 X 線散乱(SAXS)測定から，ラメラ厚はバルク球晶と同…
Corantes e pigmentos são incorporados aos polímeros principalmente para melhorar suas propriedades estéticas. Porém, estes aditivos podem afetar a estabilidade térmica e fotoquímica do material. Este trabalho teve como objetivo estudar a influência de diferentes classes de colorantes sobre a estabilidade termo-oxidati…
Type 304 and 316L stainless steels (SS) were irradiated at ambient temperature in the U.S. Advanced Test Reactor up to 2×1025n/m2 (E>1MeV). Weldings were performed under various weld heat-input levels from 1 to 10 kJ/cm for specimens containing up to 29 appm helium (He). After the welding, cross-sectional observation…
In the ongoing global warming it is required for the world to develop the new energy systems for adapting or mitigating the impacts of climate change and sustaining our prosperous society. Innovation of material science would be a crucial path for realizing the new energy systems. For innovation, large-scale simulatio…
This study investigates the effects of the flooding of the gas diffusion layer (GDL), as a result of liquid water accumulation, on the performance of a proton exchange membrane fuel cell (PEMFC). The transient profiles of the current generated by the cell are obtained using the numerical resolution of the transport eq…
Computational and experimental investigations of thermochemical resistance of carbon-ceramic composites in the combustion products of liquid rocket engine (LRE) are presented. The tests with model extensions made of the composite material (CM) were performed. The test time was about 200 s. The maximal temperature of t…
Offshore industry has evolved to meet numerous challenges, e.g. deep water, high currents, high pressure and high temperature (HPHT), and sour reservoirs, facing deepwater exploration. The trend in flowline specifications for deepwater offshore fields is a consequence of complex oil-gas field conditions, such as HPHT…
