As one of the most important characteristics of structural steels, toughness is assessed by the Charpy V-notch impact test. The absorbed impact energy and the transition temperature defined at a given Charpy impact energy level are regarded as the common criteria for toughness assessment. This paper aims at establishi…
The oxygen adsorption on Au (111) surface has been studied systematically using density function theory (DFT). The adsorption energies, adsorption structures, work functions, density of electrons and projected density of states have been calculated in wide ranges of coverage. It is found that the fcc-hollow site is th…
Iron undergoes a polymorphic phase transformation from alpha phase (bcc) to the epsilon phase (hcp) when compressed to stresses exceeding 130 kbar. Because the epsilon phase is denser than the alpha phase, a single shock wave is unstable and breaks up into an elastic wave, a plastic wave, and a phase transition wave k…
Tests were carried out in order to determine the bending strength with compression and tension force with and without glue in addition to screws on furniture corner joints in a construction case. The specimens were prepared with particleboard and medium density fiberboard (MDF) surfaced with a synthetic resin sheet. I…
Oxide fiber-reinforced Ni-base composites have long been considered as attractive heat-resistant materials. After several decades of active research, however, interest in these materials began to decline around mid-1990’s due chiefly to 1) a lack of manufacturing technology to grow inexpensive single-crystal oxide fib…
Mud bricks where commonly used in ancient Egypt by the time of the First Dynasty (Old Kingdom) c. 3000 years BCE. Ancient mud bricks were fabricated by mixing mud, sand, water and plant material followed by sun drying. Algae, and in particular diatoms, are commonly associated with mud and water and consequently diatom…
Fuel Assemblies designed and fabricated by Westinghouse Electric Sweden (WSE) to reach high burnup have been operated in the Leibstadt nuclear power plant (KKL) for seven cycles attaining an assembly average burnup above 60 MWd/kgU. The irradiation conditions in KKL featured linear heat generation rates ranging from 2…
Degassed processing (DG) is used for decreasing cast defects such as porosities or micro shrinkage. So it is very excellent method for improvement of fatigue property on casting aluminum alloy. In this study, for the aim of more fatigue property improvement of the casting aluminum alloy AC4CH, the laser peening treatm…
Свойства обратных электромагнитных волн Рё возникновение отрицательного отражения РІ ферритовых пленках, Вашковский Рђ.Р’., Локк Р.Р“.
The nuclear industry strives to reduce the fuel cycle cost, enhance flexibility and improve the reliability of operation. This can be done by both increasing the fuel weight and optimizing rod internal properties that affect operational margins. Further, there is focus on reducing the consequences of fuel failures. To…
Le carbonate de calcium precipite usuellement sous 3 formes cristallines anhydres, la calcite, la vaterite et l'aragonite. Dans des conditions de forte sursatuaration, 3 autres varietes hydratees ainsi que des associations moleculaires peuvent se former. Les conditions d'equilibre des differentes varietes ont ete calc…
Fe-Ni-BaTiO3 three-phase composites with super high dielectric constant were successfully prepared by sintering BaTiO3 with various amount of metal (Ni and Fe with a fixed mol ratio of 78∶22) in nitrogen atmosphere at 1250℃ for 2h. The impedance and the dielectric properties were measured by an Agilent 4294A precision…
Titanium dioxide nanocrystalline mesoporous thin films were prepared by the evaporation induced self assembly process onto a SnO2–F (FTO) electrode and post-functionalized by ferrocenylphosphonic acid as a grafted electrochemical probe. We showed that the pseudo-diffusive electron hopping between the redox species is…
A technique to precisely measure the efficiency of thermoelectric modules has been developed within the framework of the Japanese project "The Development for Advanced Thermoelectric Conversion Systems" supported by the New Energy and Industrial Technology Development Organization (NEDO). For modules operating in the…
Dense TiSi2–SiC and TiSi2–SiC–Ti3SiC2 composites in which SiC particles in 200–300 nm disperse, were reactively synthesized through spark plasma sintering (SPS) technique using TiC, Si, and C powders in micrometer as starting reactants. The phase constituents and microstructures of the samples were analyzed by X-ray d…
Local field-induced optical properties of Ag-coated CdS quantum dot structures are investigated. We experimentally observe a clear exciton peak due to the quantum confinement effect in uncoated CdS quantum dots, and surface plasmon resonance and red-shifted exciton peak in Ag-coated CdS composite quantum dot structure…
This paper demonstrates the reverse Doppler effect associated with wave propagation in left-handed materials using a simple circuit configuration. Virtual source motion within a left-handed medium is electrically realized using sequential switching of transmission-line taps along a left-handed transmission line consis…
Angular scatterometry, which has the advantage of good measurement precision, is an optical measurement technology based on the analysis of light scattered from periodic features, such as a linear grating, and is proposed as an alternative solution for overlay metrology. We present overlay measurements using an angula…
We have developed novel adhesion molecule-targeted double-shelled microspheres which encapsulate nitrogen. We report in vitro targeting studies utilizing these microspheres conjugated to target-specific antibodies directed towards ICAM-1 and VCAM-1. In static adherence experiments, the adherence patterns of microspher…
The formation and breakdown of the passive film are mainly controlled by ionic and electronic transport processes; processes that are in turn controlled by the electronic properties of the film. Consequently a comprehensive understanding of mechanisms behind passivity and localised corrosion require a detailed percept…
