In this study, atmospheric pressure plasma (APP) treatment was applied to polypropylene (PP) fabric with non‐polymerizing gases, such as air, argon, and nitrogen. Properties of the APP‐treated samples including low‐stress mechanical behavior, air permeability, water vapor permeability, and thermal characteristics were…
For many decades, Martindale’s theory on yarn unevenness has been widely used as a reference for staple yarn production and its quality control. With the yarn count becoming higher and higher and with the decrease in the yarn irregularity, the index of irregularity (I), defined on the basis of Martindale’s limit yarn…
Abstract Poly‐ N ‐vinylcarbazole–polyaniline (PANI) composites were synthesized using different loading concentration of aniline (0.025–0.1 M) for their microwave absorption characteristics. The obtained composites were studied by Fourier transform infrared spectroscopy, thermogravimetric analysis technique, and atomi…

The asymmetric unit of the title compound, C(16)H(17)ClNO(2)S(+)·HSO(4) (-), (I) [systematic name: (+)-(S)-5-[(2-chloro-phen-yl)(meth-oxy-carbon-yl)meth-yl]-4,5,6,7-tetra-hydro-thieno[3,2-c]pyridin-5-ium hydrogen sulfate], contains two independent cations of clopidogrel and two independent hydrogensulfate anions. The…
The present study describes design and development and use of an image processing system to characterize and visualize the configuration of fibers in yarn in extended mode. An especially dedicated instrument and software for data acquisition and analysis are the unique features of the system. It is capable of grabbing…
Arsenic-doped ZnMgO films were fabricated on SiO 2 by the radio frequency magnetron sputtering technique at different substrate temperatures during growth.The yielded films were characterized by room temperature Hall measurement, x-ray diffraction, x-ray photoelectron spectroscopy, scanning electron microscopy, second…
A noninvasive methodology to evaluate and classify electrical system failures is presented in this work. It is based on the electrical system magnetic signature recognition by using the wavelet signal decomposition and the resulting variance spectrum evaluation, respectively. The proposed methodology was validated by…
Single phase and epitaxial Cu 2 O thin films were synthesized by thermal oxidation of Cu films deposited on GaN/sapphire substrates using electron beam evaporation. A transition of the conduction type was observed when the vacuum annealing temperature was varied from 400 to 500 °C. Current–voltage characterization con…
Abstract Spherical indium tin oxide (ITO) nanoparticles were synthesized by combustion method using citric acid as fuel and nitrates as oxidizer. The obtained ITO nanoparticles were characterized by TG‐DSC, FT‐IR, XRD, BET, TEM, and SEM. The ITO nanoparticles grew steadily with the increase of heat treatment temperatu…
Abstract NiFe 2 O 4 nanorods have been successfully synthesized via thermal treatment of the rod‐like precursor fabricated by Ni‐doped α‐FeOOH, which was enwrapped by the complex of citric acid and Ni 2+ . The morphology evolution during the calcination of the precursor nanorods was investigated with transmission elec…
The quick and the dry: Fast-absorbing and quick-drying wool fabrics with good washing durability are fabricated by functionalizing reactive siloxane monolayer on wool fiber surface, followed by grafting an ultrathin silica nanoparticles layer using an in situ growth method. The new properties are maintained even after…
Expressions for the pre-exponential factor σ 3 and the thermal activation energy ε 3 of hopping electric conductivity of electrons via hydrogen-like donors in n-type gallium arsenide are obtained in the quasiclassical approximation. Crystals with the donor concentration N and the acceptor concentration KN at the inter…
We present the results of a combined experimental and theoretical investigation of rolling elastic ribbons. Particular attention is given to characterizing the steady shapes that arise in static and dynamic rolling configurations. In both cases, above a critical value of the forcing (either gravitational or centrifuga…
Abstract To obtain highly transparent isotactic polypropylene sheet by an industrial process, various factors contributing to transparency were analyzed. Two kinds of sheets were prepared for analysis. The one was extruded by a direct single belt process as the quick quenching system. And the other was extruded by a c…
Abstract A hierarchical model of heat transfer for the thermal analysis of electronic devices is presented. The integration of participating scales (from nanoscale to macroscales) is achieved by (i) estimating the input parameters and thermal properties to solve the Boltzmann transport equation (BTE) for phonons using…
2,4-Diamino-6-phenyl-1,3,5-triazines carrying one or two semiperfluorinated chains at the phenyl substituent have been investigated in binary mixtures with partially fluorinated benzoic acids by polarizing microscopy, differential scanning calorimetry, and X-ray diffraction. The number and positions of the fluorinated…
The paper explores the potential of a recently developed special front tracking method in the identification of the interface between columnar and equiaxed structures formed during a binary alloy solidification, driven by thermosolutal convection. The method, based on theoretical and experimental dendrite tip kinetics…
Reductive cleavage of C(6)F(5)SeSeC(6)F(5) with elemental M (M = Zn, Cd, and Hg) in pyridine results in the formation of (py)(2)Zn(SeC(6)F(5))(2), (py)(2)Cd(SeC(6)F(5))(2), and Hg(SeC(6)F(5))(2). Structural characterization of the Zn and Cd compounds reveals tetrahedral coordination environments, while the Hg compound…
This paper presents the adjoint variable method (AVM) for finite-element (FE) analysis of eddy current problems based on complex variables. In the sensitivity analysis based on FE analysis of time-harmonic eddy current fields, the functions for which sensitivity is evaluated are often real-valued, while unknown variab…
