The electronic structures and, optical and magneto‐optical properties of a newly found Zintl compound EuIn2P2 have been investigated within the density‐functional theory using the highly precise full‐potential linear‐augmented‐plane‐wave method. Results of detailed investigation of the electronic structure and related…

High-k insulator films of HfO2, Y2O3, and CeO2, were prepared on Nd2Ti2O7 (NT) ferroelectric to form metal-ferroelectric-insulator-semiconductor structures. The NT is a candidate ferroelectric material for use in a metal-ferroelectric-insulator-semiconductor field effect transistor (FET) with low permittivity and a hi…
The structure and the magnetic properties of -Fe(Si) phase precipitated in the Finemet alloy, and some factors influencing the magnetic properties of -Fe(Si) phase are investigated by first-principles calculation based on the density functional theory. From the angle of electron spin, the magnetic properties of -Fe(Si…
The results for the ac conductivity over temperature range (180–300 K) and frequency range (2–20 kHz) for the GexSe80−xPb20 glassy films deposited thermally in vacuum are presented. The temperature dependence of ac conductivity reveals the signature of correlated barrier hopping transport in the frame work of Meyer‐Ne…
Abstract: This paper considers cylindrical bending of the plate containing a crack parallel to plate’s faces. The analytical model of the problem is obtained using the improved theory of plates bending, which considers transverse deformation of the plate. Received analytical results are compared with the numerical dat…
The polycrystalline sample of tungsten bronze (TB) structured compound Na2Pb2Pr2W2Ti4V4O30, sample was prepared by a mixed‐oxide / solid state reaction technique. Preliminary structural studies with X‐ray diffraction data shows the formation of single phase compound. Electrical properties of the material have been stu…
The surface of welded joints in X70 steel pipeline was processed by laser shock wave, its mechanical behaviors of tension fracture were analyzed with tension test, and the fracture morphologies and the distributions of chemical element were observed with scanning electron microscope and energy dispersive spectrum, res…
Nitriding process of medium carbon ferromanganese was carried out in the solid state, on lab and bench scale at temperature range 1023-1323 K using different nitrogen and hydrogen pressures. The influence of H 2 /N 2 gas ratio, temperature and time on nitriding process of fine (-2 mm) medium carbon ferromanganese were…
The process of Мо-С multilayer coatings deposition by means of gas-phase method sedimentation with metal-organic compounds application is developed. The tribological test of Мо-С coatings revealed the perspectivity of developed coatings for mear resistance increase and friction coefficient decrease of friction pair sl…
The intent of this chapter is to highlight the contributions of large animal models including pigs, sheep, goats, dogs, and nonhuman primates. These species are crucial for clinical translation of new cell and tissue engineering approaches for the treatment of human diseases. Choice of species, age, and model validati…
The topic of chemical oxidative degradation in rotational molded polyethylene (high-density cross-linked) chemical (sodium hypochlorite) storage tanks is an industry problem that ranks at the top of current business issues for manufacturers of chemical storage tanks. The degradation of these tanks not only compromises…
In this article the seam slippage characteristics of unbalanced weave fabrics are analysed. The slippage resistance of yarns at a seam in woven fabrics is a very important factor, and strong claims have been made about this property. Preliminary investigations showed that balanced and unbalanced woven fabrics must be…
Detailed time-and-space-averaged structure of MgSO4 in the concentrated aqueous solutions was investigated via X-ray diffraction with an X’pert Pro θ-θ diffractometer at 298 K, yielding structural function and radial distribution function(RDF). The developed KURVLR program was employed for the theoretical investigatio…
Glass shells made from the pyrolysis of silicon-doped glow discharge polymers (Si-GDP) are particularly interesting for many noncryogenic target applications. We investigated the possibility of developing millimeter glass shells with >10-μm-thick walls to achieve a half-life of several months. Although previous studie…
Recently,there have been the increase of ship size and the development of oil and gas in arctic region.These trends have led to the requirements such as high strength,good toughness at low temperature and good weldability.The high performance structural steels for shipbuilding and arctic offshore structure have been d…
Sputter coating of beryllium on spherical mandrels has been used at Lawrence Livermore National Laboratory and at General Atomics to produce graded, copper doped beryllium shells. While these coatings have consistent microstructure and acceptable void content, different coaters produced different results with respect…
L’effet de l’extrait aqueux (100-1400 mg/kg) des racines de Dorstenia psilurus a ete etudie sur les ulceres gastriques induits (au melange HCl (150 mM)/EtOH(60%)) chez les rats mâles de la souche wistar. Pour ce fait, nous avons adopte une recherche experimentale avec un diagramme d’etude Cas-Temoin. Vingt-cinq rats m…
Epoxy composites consisting of sisal, glass fibers and Multi walled carbon nanotubes(MWCNTs) were fabricated by three different methods like Hand layup, unstretched fibers and stretched fibers methods. Test specimens prepared as per ASTM standards using Vinyl ester thermosetting resin as matrix and reinforced with dif…
The excitation threshold for subharmonic generation plays an important role in accurate prediction of various subharmonic scattering related observations. The classical understanding suggests that minimum subharmonic threshold occurs near twice the resonance frequency. We numerically show that for a number of models—N…
