The characteristics of neutron diffraction applied to the study of Ferromagnetic Shape Memory Alloys are revised. Main studies refer to crystal structure, preferential site occupancy, variant reorientation and magnetic moment distribution in the alloys
In nature, free-ranging raccoons typically do not live longer than 2 y; most raccoons in the wild die young due to accidents and diseases. Therefore, few data are available regarding lesions associated with advancing age in raccoons. This communication documents the lesions present in raccoons (7 male; 3 female) that…
A much larger amount of bonded hydrogen was found in thick nanocrystalline diamond (NCD) films produced by only adding 0.24% N 2 into 4% CH 4 /H 2 plasma, as compared to the high quality transparent microcrystalline diamond (MCD) films, grown using the same growth parameters except for nitrogen. These experimental res…
Neutron Resonance Transmission Analysis (NRTA) is an analytical technique that uses neutrons to assay the isotopic content of bulk materials. The technique uses a pulsed accelerator to produce an intense, short pulse of neutrons in a time-of-flight configuration. These neutrons, traveling at different speeds according…
Fabrication of low resistivity ohmic contacts to N polarity gallium nitride crystal is an important issue for the construction of the vertical current flow devices like laser diodes and high brightness light emitting diodes. Gallium nitride is a challenging material because of the high metal work function required to…
Peritoneal adenomatoid tumours are rare benign neoplasms originating from mesothelial cells. We present a case of peritoneal adenomatoid tumour penetrating into the bowel wall and causing massive intra- and extraluminal bleeding.
The violent free-surface motions and the corresponding impact loads are numerically simulated by using the refined Moving Particle Simulation (MPS) method, which was originally proposed by Koshizuka and Oka (1996) for incompressible flows. In the present method, accuracy and efficiency are significantly improved compa…
Processes of aniline polymerization in perfluorinated polysulfonic acid MF-4SK solution are studied by UV-spectroscopy. Membranes with polyaniline-modified surface layer are synthesized. It is shown by voltammetry and potentiometry that the composite materials demonstrate asymmetric ion transfer with respect to proton…
The mineral fettelite, [Ag 6 As 2 S 7 ][Ag 10 HgAs 2 S 8 ], has been recently structurally characterized. On the whole, the structure can be described as a regular succession of two module layers stacked along the c-axis: a first module layer (labeled A) with composition [Ag 6 As 2 S 7 ] 2- and a second module layer (…
The interrelation between the transport properties of pervaporation membranes (used to separate toluene-n-heptane mixtures) and the structure of poly-γ-benzyl- L -glutamate diffusion layers has been studied. The decrease in the membrane selectivity while increasing the flux at the transition from 3 to 50 wt % toluene…
To form SiCH films with a high carbon content using plasma-enhanced chemical vapor deposition (CVD), isobutyl trimethylsilane (iBTMS) and diisobutyl dimethylsilane (DiBDMS) were examined as precursors for a low-k cap layer and Cu diffusion barrier at the top of Cu lines. We elucidated the relationship between the stru…
In this work new results about the influence of cathodic hydrogen on passivity and corrosion resistance of 2205 duplex stainless steel are described. The results were discussed by taking into account hydrogen charged samples and without hydrogen. The corrosion resistance to pitting was qualified with the polarization…
The problems of diffusion in solid are widely treated as those of numerical analyses such as mechanisms of hydrogen diffusion which causes embrittlement, boundary micro crack initiation and growth under high temperature creep condition and stress and electro-migration due to vacancy diffusion in LSI circuit. In this p…
The selective catalytic reduction (SCR) technology is well established and used worldwide to control the emissions of NOx from stationary sources: it can be broadly described as passing a hot exhaust gas over a catalyst in the presence of nitrogenous reductants, such as ammonia or urea. The SCR is also currently emplo…
The effects of sonication time, nitrogen, N2(g), increasing temperature, dissolved oxygen (DO) and titanium dioxide (TiO2) concentrations on the sonodegradation of polyaromatic hydrocarbons (PAHs) in petrochemical wastewaters were investigated. Sonication alone without N2(g), DO and TiO2 provided 80% maximum PAH yield…
Hexagonal barium ferrites have wide applications as anti radar filler in coatings and other composites. M type barium hexagonal ferrite (BaFe12O19) has been synthesized by citrate sol gel auto combustion method using barium nitrate and ferric nitrate as sources for cations and citric acid as fuel. The effect of cation…
Over the past few decades, the interest in magnetizable nanocolloids has steadily increased as a result of the growing number of applications which can be designed both in the field of biotechnology and biomedicine. To improve the colloidal stability the particles have to be wrapped in a cushion of adsorbing molecules…
Skin becomes wrinkled, saggy, thinner and lose elasticity with aging. Although various program delay skin aging, there were not many information about the effects of exercise to facial skin aging. PURPOSE: We investigated the effects of resistance training to skin elasticity of facial mimetic muscle in middle-aged wom…
Reliability of conductive joints manufactured using electrically conductive adhesives (ECAs) depends mainly on their internal homogeneity. During tests of the reliability of ECAs, a significant incidence of internal inhomogeneities was observed in the joints made by one and two-component adhesives. The reason for the…
A novel horizontal laminar flow (HLF) cleaning is proposed for removing contamination from highly integrated semiconductor devices with high pattern densities. The proposed HLF cleaner contains fluid flow plates that realize horizontal laminar flow in the cleaning bath. This configuration effectively reduces cross con…
