Les alliages de zirconium sont utilises comme materiaux de gainage dans les Reacteurs a Eau Pressurisee. Or, en fonctionnement, la corrosion et l’hydruration sont des facteurs limitant l’utilisation des alliages Zircaloy-4 et sont a l’origine du developpement de l’alliage Zr-1Nb. Afin d’ameliorer notre comprehension d…

Conjugation of synthetic materials with cell-responsive biologically-active molecules, in addition to providing structural support and release of biomolecules in the regenerating region, can provide the signaling factors required to initiate the cascade of cell migration, adhesion, differentiation, maturation, growth…
The reaction of cerium chloride heptahydrate with salicylic acid and thioproline produced [Ce(Hsal) 2 ·(tch)]·2H 2 O [Hsal = salicylate (C 7 H 5 O 3 − ), tch = thioprolinate (C 4 H 6 NO 2 S − ))], which was isolated and characterized by IR, elemental, chemical, and thermogravimetric analysis. The standard molar enthal…
We describe an improved reaction rate equation for simulating ignition and growth of reaction in high explosives. It has been implemented into CALE and ALE3D as an alternate to the baseline the Lee-Tarver reactive flow model. The reactive flow model treats the explosive in two phases (unreacted/reactants and reacted/p…
Energia nuclear consiste no uso controlado das reações nucleares para a obtenção de energia, tais núcleos, quando sofrem essa modificação, liberam uma quantidade expressiva de energia. Nos reatores nucleares, essa energia é aproveitada para gerar calor e na sequência energia elétrica pela movimentação de turbogeradore…
The hot band of a commercial continuous cast (CC) Al–Mg–Mn alloy was annealed at different temperatures ranging from room temperature to 510°C for 3 h. The evolution of microstructure and crystallographic texture was investigated during the annealing treatment. It was found that the recrystallised alloy exhibited a se…
We propose Kondo fluctuation mechanism of superconductivity, differentiated from the spin-fluctuation theory as the standard model for unconventional superconductivity in the weak-coupling approach. Based on the U(1) slave-fermion representation of an effective Anderson lattice model, where localized spins are describ…
Misprints in Eqs. (6), (9) and (13) of the article by Dmitry Pozdnyakov, Phys. Status Solidi B 247, 134 (2010), are corrected. Equation (6): Equation (9): Equation (13):
Abstract Helium‐aided sintering of porous unsintered glass is a complex multiscale process, characterised by three different timescales, namely, that of helium diffusion, heat conduction, and radial shrinkage of the glass core. This work presents a multiscale model for quantifying heat and helium diffusion in a shrink…
DNA markers used in assisting selection method is a safe method in breeding process, due to deletion of environmental conditions, and it is an important tool in preparing linkage map and QTLs mapping. In mulberry silkworm that is, foundation of world sericulture, its major production- economic characteristics are poly…
The adsorption of a novel pyrene-based carbon nanotube surfactant is depicted on the cover. The aromatic pyrene unit adsorbs on the nanotube sidewall by π–π-stacking interactions. Water solubility is then provided by a Newkome-type dendrimer on the periphery of the anchoring group. Interestingly, the dispersing agent…
Effect of Sn addition on the self-propagating high temperature synthesis reaction has been investigated. The results show that Sn serves not only as a diluent but also as a reactant and reacts with Ti to form Ti6Sn5 phase. As the Sn content ranges from 6 to 15 wt-%, the combustion temperature of the system decreases a…
The crystal-field energy level calculation of the 4f(7) ion Gd(3+) in the crystal Cs(2)NaGdCl(6) has fitted 45 levels with standard deviation 12 cm(-1), with the energy parameters being consistent with those from other studies. The resulting eigenvectors have been employed in the calculation of two-photon absorption (…
Abstract A detailed study on the influence of an InGaN interlayer between the GaN buffer and InN epilayer on the microstructural properties of the InN layer is reported. Using high‐resolution X‐ray diffraction measurements the mosaicity of MOVPE grown InN epilayers deposited directly on c‐plane sapphire, on GaN buffer…
IN THE MID-1970S, one of my first jobs out of college was with a global engineering and construction firm. When attending meetings in the chief engineer’s office, I was struck by a 4- × 4-foot photograph that covered most of one wall. It showed, in sharp black and white, a nuclear power plant under construction. The e…
This paper describes a robust and accurate black-box macromodeling technique, in which the constitutive equations combine both closed-form delay operators and low-order rational coefficients. These models describe efficiently electrically long interconnect links. The algorithm is based on an iterative weighted least-s…
An RF-assisted closed-field dual magnetron sputtering system was developed to characterize the plasma and the ionization fraction of sputtered material to provide a suitable system for depositing optical thin films on large-area substrates at low temperatures (<130 °C). The 'prototype' system consists of dual 76 mm dc…
Abstract First irradiation experiments on the cyclotron ion accelerator DC‐60 are presented. LiF crystals were irradiated with 147 MeV Kr+14 ions in the fluence (Φ) range 8 × 1010–3 × 1012 ions/cm2 at a beam current 20 nA/cm2 (corresponding to a flux ϕ ≈ 9 × 109 ions/cm2 s). The main electron microdefects (F‐type colo…
Low carbon steel strip was heat treated to generate four different starting microstructures (fine and coarse polygonal ferrite, acicular ferrite and bainite) for investigating their influence on texture development during cold rolling and annealing. The starting materials were cold rolled to 50–90% reduction and annea…
