To improve a void drift model incorporated in a subchannel analysis code, experimental data have been obtained for vertical air-water two-phase flows in several test channels of two- and multi-subchannel systems. In order to know the effects of the lattice of fuel rods on the void drift, the channels made up of two su…
Coffee foaming fractions (total and its sub-fractions: proteins/melanoidins fraction and polysaccharides fraction) were extracted from defatted and raw commercial roasted ground coffee. All the extracted fractions were analyzed using an interfacial rheometer CIR 100 (FTA) operating in time sweep mode, in order to stud…
Left handed (LH) ferrite circulators composed of the nonreciprocal LH microstrip lines using perpendicularly magnetized ferrite substrate and operating at the negative permeability frequency are studied. Following three types of circulators are proposed: a disk shaped circulator having broadband characteristics and hi…
The thermal quenching of 3.0-eV photoluminescence (PL) in oxygen-deficient α-Al 2 O 3 single crystals upon preliminary UV irradiation has been studied. It is established that the parameters of the PL quenching kinetics vary within broad limits depending on the duration of UV pretreatment. The compensation effect relat…
The NIR-FT Raman, FT-IR spectral analysis of potential NLO material P-Amino Acetanilide is carried out by density functional computations. The optimized geometry shows that NH2 and NHCOCH3 groups substituted in para position of phenyl ring are non-planar which predicts maximum conjugation of molecule with donor and ac…
OFHC Cu samples were subjected to shock loading using plane wave HE lenses to produce a uniaxial Taylor wave profile (shock followed by immediate release). Upon arrival of the shock wave at the free surface of the sample, the wave is reflected and propagates back into the sample as a release wave. It is the interactio…

Pure ceria and ceria-yttria solid solution powders with formula Ce1–xYxO2, where 0 < x < 0.30 were prepared by the coprecipitation-calcination method. The samples were sintered at 1250–1600 °C for 2 hours. The XRD method was used to determine cell parameters of the samples. Their electrical properties were investigate…
The dynamical stability of carbon nanotubes embedded in an elastic matrix under timedependent axial loading is studied in this paper. Efiects of van der Waals interaction forces between the inner and outer walls of nanotubes are taken into account. Using continuum mechanics an elastic beam model is applied to solve th…
Abstract The Li –Sn system was critically assessed by means of the CALculation of the PHAse Diagram (CALPHAD) technique. The solution phases (liquid, body-centered cubic (αLi), body-centered tetragonal (βSn), hexagonal close-packed (βLi) and diamond (αSn)) were modeled with the Redlich-Kister equation. The intermetall…

Density and surface tension of liquid Ni-Cu-Fe alloys have been measured over a wide temperature range, including the undercooled regime. A non-contact technique was used, consisting of an electrom ...
High strength steels have been developed in order to improve fuel economy as well as to increase safety. The conventional Si-Mn bearing high strength steels have the drawback of poor galvanisability due to the presence of complex Si-Mn oxides on their surface. In order to improve the galvanisability of Si-Mn steels, t…
Magnetic fluids mainly consist of nano sized iron oxide particles (Fe3O4 or γ- Fe2O3) that are suspended in carrier liquid. In recent years, substantial progress has been made in developing technologies in the field of magnetic nanoparticles, microspheres, magnetic nanospheres and ferrofluids. Techniques based on usin…
Polyurethane-based composites have become an accepted alternative in the pultrusion industry, especially for applications requiring high strength and durability. Pultruded composites based on two-component polyurethanes are now widely known to exhibit superior strength and toughness compared to traditional pultrusion…
This work investigates the effect of warp and weft density on the bending properties of polyester viscose woven fabrics. 25 lightweight woven fabrics of different densities were produced and evaluated with three methods; KES, extraction, and a newly-suggested method. The test results of the three methods were compared…
A new method of pipe joining using shape memory alloys (SMAs) is proposed in this study to obtain the maximum and uniform joining stress. Fe-based SMAs, regarded as potential alloys for pipe couplings, is not so widely industrialized as anticipated. The major obstacle is error of pipe size, which causes a gap between…
Abstract In this article, we review the possibility of combining conjugated polymers with nanometer-scale devices (nanodevices), in order to introduce the properties associated with conjugated polymers into such nanodevices. This approach envisages combining the highly topical disciplines of polymer electronics and na…
The square-planar AuIII complex of the unsymmetrical tfadt dithiolate ligand (tfadt: 2-(trifluoromethyl)acrylonitrile-1,2-dithiolate) is found to exhibit conformational polymorphism in its n-Bu4N+ salt, as both cis and trans isomers were found to crystallize separately in the same crystallization batch. Electrocrystal…
The dependence of electron field emission (FE) characteristics of porous silicon (por-Si) prepared by anodisation at low current density without external bias is investigated. Effective electron FE from por-Si on p-Si flat surface was revealed. With growth of anodisation current (from 1 mA/cm² to 5 mA/cm²) the electro…
