A consistency between the Darken method and the Onsager representation for cross diffusion in multicomponent system is shown. The justification is made by defining new sets of forces and fluxes linearly interrelated by a symmetric matrix of phenomenological coefficients. For the first time, the system of the component…
In Textile industry, production is mostly key concern for Industry owner. This always has attracted researchers and machines manufacturers to make new developments in process and machines. Air-jet is one of the leading and successful highest productive weaving machines. However, it is now well established that due to…

It is shown that impedance measurements can be used to quantify transmission line damage. A device design is given for detecting the complex impedance of a transmission line at high frequencies without disrupting regular service. A complementary device is presented that simulates an open circuit at the excitation freq…
The influence of reduction on the distribution of axial, tangential, and radial residual stress over the cross section of cold-finished steel rods is experimentally studied. Computer modeling of the flexural rigidity of the rods indicates that, with 5–34% reduction, which is the range used in practice, the rigidity of…
Solar and wind energy are becoming the fundament of the power supply system. However, the increasingly significant amount of renewable electrical power associated with natural intermittency due to varying weather conditions requires flexible storage options. One promising path is the solid oxide electrolysis cells (SO…
Six types of high-permittivity and low-loss electromagnetic (EM) composites based on a polydimethylsiloxane (PDMS) or cyclo-olefin polymer (COP) host matrix, reinforced by Ba0.55Sr0.45TiO3 or MgCaTiO2 microparticle fillers with volume loading concentration up to 49 vol. %, have been prepared and characterized up to 20…
The crystal structure and paramagnetism in the pyrazinamide containing copper(II) 2-nitrobenzoate single crystal were investigated using X-ray diffraction, Fourier-transform infrared spectroscopy, and electron paramagnetic resonance techniques. X-ray diffraction analysis shows that the complex crystallizes in monoclin…
This study sets out to explore the space charge characteristics of high voltage direct current (HVDC) cable grade crosslinked polyethylene (XLPE) using different electrode materials and configurations, ranging from sputtered gold to thermally bonded semi-conducting materials. The existence of both homo and hetero char…
We evaluate the dielectric characteristic of polymeric materials for spacecraft irradiated by a high energy proton using results of space charge distribution and conduction current measurement under DC. From the results, we observed that space charge polarization was produced in the irradiated bulk and the conductivit…
[FeLX 2 ]Y [L = N,N '-ethylenebis(salicylimine) (salen), N,N '-ethylenebis(acetylacetonylimine) (acen), or N,N '-ethylenebis(3-methyloxysalicylimine) (vanen); X = imidazole or N -methylimidazole; Y = BF 4 , ClO 4 , or BPh 4 ] compounds have been prepared and studied by means of EPR and magnetic susceptibility measurem…
Polyaniline (PANI) was successfully deposited by means of cyclic voltammetry technique from 0.10 M aniline containing 0.30 M oxalic acid and 1 g/l H3BO3 solution on AISI 4140 steel electrode. In this investigation nominate scan rates 25, 50, 75, and 100 mV/s have been examined. PANI film was characterized using optica…
In carbon nanotube (CNT) arrays, unequal current contribution from each emitter to the overall emission current would lead to non-uniform field emission (FE) performance and emitter failure. Therefore, we propose a novel field emission microscopy (FEM) method that allows us to visualize and record the FE performance o…
TiO2, B2O3, H3BO3, B4C and carbon black were used as the raw materials to prepare TiB2 powders by carbothermal reduction method. The influence of different content of carbon black (13.6~14.8 wt%) on products was discussed. The effects of different boron sources and holding time (10~50 min) on the microstructure of TiB…
Adsorption of influenza A viruses and their antibodies on golden surfaces, thin films of polyaniline and polyaniline complex with polysulfonic acids, has been studied. The composition of interpolymer complexes was found to influence both the surface relief of synthesized films and the adsorption efficiency. Moreover,…
Duplex stainless steels when subjected to temperatures above 600 ° C have its tenacity decreased by the formation of sigma phase. This phase has high hardness and is rich in chromium and reduces the matrix of this element. In this study, field line density measurements, obtained in the reversibility region of magnetic…
Based on the coherent potential approximation, the method of calculating the electronic structure of nonstoichiometric and hyperstoichiometric compounds with strong electron correlations and spin-orbit coupling has been developed. This method can be used to study both substitutional and interstitial impurities, which…
The influence of the holding time upon annealing on the temperature of the viscous–brittle transition (temperature of embrittlement) T f in a cobalt-based amorphous alloy of the composition Co69Fe3.7Cr3.8Si12.5B11 with a very low saturation magnetostriction λs (<10–7) has been studied. It has been established that the…
Polymeric nonionic surfactant pluronic P123 significantly increases the distribution ratio of nanodiamonds in the aqueous-organic liquid systems.
H. Xu, J. Zhang, and co-workers synthesize anisotropic 2D-layered rhenium disulfide with high crystal quality and uniform monolayer thickness. As described on page 5019, tellurium-assisted epitaxial growth on a mica substrate is chosen to generate such structures.
