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…
Self-powered space and water heating systems operate entirely on fuel combustion with no need for externally generated electricity. Excess power can be used to charge batteries or be fed into the household grid to provide electricity for other electrical loads. Self-powered heating systems have the potential for high…
The mechanism of UV and EB cure processes for porous low-k SiCOH materials was investigated by using experimental results obtained using PECVD and SOD films as well as simulated results. Both UV and EB cures induced dielectric constant change and Young's modulus improvement because Si-OH elimination (moisture removal)…
High production machining at high cutting velocity and feed generates large amount of heat and high cutting temperature, which shortens the tool life and deteriorates the job quality. This problem becomes more acute when the jobs are difficult to machine and are to be used under dynamic loading. The conventional cutti…
We have monitored the physical processes linked to electrochemical processes in situ occurring at MmNi 3.6 Mn 0.4 Al 0.3 Co 0.7 alloy negative electrodes using an acoustic emission (AE) technique in terms of waveforms, power spectra, and time history of the AE signals. Hydrogen evolution was characterized by an AE wav…
Abstract We describe the experiments on a magnetically-induced drift of the easy axis on a soft surface of photoaligning material fluoro-polyvinyl-cinnamate. We found unexpected partial relaxation of the drift of the easy axis after switching the magnetic field off. This relaxation cannot be explained in a framework o…
Magnetic properties of palladium and palladium-platinum alloy (Pd-Pt) of different hydrogen content were measured in a hydrogen atmosphere at ambient temperature using a superconducting quantum interference device (SQUID) magnetometer. It was found that the magnetic susceptibility of Pd and Pd-Pt alloy decreased with…
