The ACR-1000™ design has evolved from AECL’s in depth knowledge of CANDU® systems, components and materials based on the CANDU 6 design, as well as the experience and feedback received from owners and operators of CANDU plants. The ACR® design retains the proven strengths and features of CANDU reactors, while incorpor…
The today's determination of residual power of nuclear fuel in containers bases on differential equations, which describe the creation and the destruction of nuclides in the fuel. The Nuclear Regulatory of Slovak Republic requires the verification of present methodology alternatively. The new methodology and achieved…
The effects of high nitrogen (N2) pressure and thermal treatment on the adhesion between a silicon film and a polyethersulfone (PES) substrate during crystallization by excimer laser annealing (ELA) were investigated using silicon nitride (SiNx) as the barrier film for the fabrication of polycrystalline silicon (poly-…
First-Principles Study of Electron Transport in Single-Walled Carbon Nanotubesthat are 2 to 22 nm in Length.
Substituted polythiophenes and polycarbazoles are materials of great interest as charge-carrier transport materials and have been utilized in PLED and FET applications. The layer-by-layer (LbL) self assembly has been used to fabricate polymer thin films on any substrates. The multilayer polymer thin films are construc…
The modified Drucker‐Prager Cap elasto‐plastic constitutive model is used for the calculation that performed using the finite element code ABAQUS 6.4 to simulate densification of alumina powder of complex shaped sample. Four‐node axisymmetric elements were used for the powder compact and two‐node axisymmetric rigid su…
Residual and interface stress of SiO2 and Nb2O5 films on glass, PC, and PET have been investigated. When Nb2O5 was coated on SiO2, the interface stress was tensile. While coated films reversely, it was compressive.
Intermetallic alloys of Ni-Al have important applications in high temperature anti-corrosive coatings, engine and turbine related materials, and shape memory devices. Predicting failure behavior of these materials is difficult using purely continuum model, since several of the material constants are complicated functi…
A vacuum‐ultraviolet bending‐magnet beamline for circular dichroism (CD) experiments has been designed. To maximize the photon flux and minimize the focused beam size, a cylindrical mirror and a cylindrical grating with independent optical functions are utilized. The beamline can collect a 30 mrad horizontal by 7 mrad…
Fuji Electric had developed the low pressure oxygen plasma technology for mild decomposition and mineralization of an organic material such as ion exchange resin. This method is suitable for radioactive spent resin volume/weight reduction and stabilization for final disposal. On this process, the ion-exchange resins a…
We experimentally demonstrate significantly enhanced second harmonic generation using nanoengineered plasmonic nanocavities of core-shell structures (BaTiO3/Au). An enhancement factor of over 500 is measured in the second harmonic scattering efficiency compared to the bare core.
Recent advances in pressure-induced superconductivity were reviewed about 3d-metal oxides including high-Tc cuprates, spin-ladders, and Fe-based pnictides. The dome-shaped pressure dependence of critical temperature (Tc) was focused on as a key word throughout this article. The origin of the Tc domes was investigated…
有機無機層状ペロブスカイト化合物は，分子式(H3N-CnH2n-NH3)PbX4(X=I, Br)で表され，構成成分である有機物(XH3N-CnH2n-NH3X)と無機物(PbX2)が自己組織的に超格子構造を形成する興味深い物質である．有機バリアー層と無機井戸層が交互に積層し，層間のバンドギャップ差により無機層領域に安定な励起子を形成することから，優れた非線形光学特性や発光特性を示すことが明らかとなっている．本研究では，種々の π 共役系オリゴマーを層状ペロブスカイト化合物の有機層に導入した有機・無機半導体超格子の作製を検討し，構造解析，および光学特性評価を行い，π 共役系オリゴマーの導入が特性に与える影響を調べた．チオフェン/フ…
We report here an effective method for the fabrication of a large number of carbon nanotube (CNT) triode-type micro-cathodes. Our technique combines composite electroplating and micromachining, avoiding the tedious direct growth and the screen-printing procedures conventionally used to fabricate such structures. The e…

Bi-Sb alloy is a promising thermoelectric material that has a good thermoelectric performance at temperature below the freezing point. This material is useful for Peltier refrigeration and/or thermoelectric power generation recovering cold potential from LNG. We attempted to synthesize nanoparticles of the Bi-Sb alloy…
The two Units of TianWan Nuclear Power Station (phase 1) are in their third fuel cycle operation now. China Nuclear Power Engineering Co., Ltd. (CNPE) has finished the reload design of Unit 1 and the check on Russia’s computation of Unit 2 in the third cycle. From the forth cycle on, the in-core reload design will be…
The computational window of photonic crystals is modeled by a staircase approximation to compute band structures with methods based on finite differences. Particularly, the treatment of discretization points outside the computational window is described.
We present bulk synthesis of anatase titania atomic wires with uniform diameters of approximately ~4-5 A¿ which are as thin as about two to three Ti-O bonds across. The synthesis was realized by a nonhydrolytic approach, which carefully controls the formation of a titanium-containing precursor from the reactions of ti…
