In this article, a novel chromium-free passivation agent contained sodium molybdate, sodium citrate, sodium phosphate, tannin, 1-hydroxyethylidene-1, 1-diphosphonic acid (HEDP) and cobalt nitrate was prepared. The component content of the chromium-free passivation agent was firstly determined by using the single varia…
Solvent-free polyurethane (SFPU) has a fast curing film-forming speed, making the foam and coating layer very dense. Therefore, this film structure has poor hygienic properties. Here, we propose a strategy for introducing double-shell hollow TiO 2 microspheres (S@S-TiO 2 ) having a large specific surface area and a sp…
Foam fractionation is one of the novel techniques used nowadays for the wastewater treatment. The present paper discusses the removal of methylene blue dye by using a surfactant, sodium dodecyl sulfate, as a collector, by semi-batch foam fractionation technique. The influence of operating variables like aeration rate…
We present a general nonequilibrium Green's function formalism for modeling heat transfer in systems characterized by linear response that establishes the formal algebraic relationships between phonon and radiative conduction, and reveals how upper bounds for the former can also be applied to the latter. We also propo…
Carbon fiber–reinforced polymers (CFRPs) are often exposed to solid particle erosion wear due to small particles moving freely in the atmosphere or in the environment and their impact on aircraft bodies. In this study, fiber weaves of CFRP composite materials of the following types were produced: unidirectional (U), p…
A series of 5-(pyren-1-yl)penta-2,4-diyn-1-yl N -phenylcarbamates and N -benzylcarbamates were synthesized. Phenyl groups in the N -phenyl and N -benzyl moieties were unsubstituted ( H-0 and H-1, respectively) and 3,4,5-trialkoxy substituted ( C m O-0 and C m O-1, respectively), in which the alkyl groups introduced we…
We develop the combinatorics of edge symmetry and edge colorings under the action of the edge group for icosahedral giant fullerenes from C80 to C240. We use computational symmetry techniques that employ Sheehan’s modification of Pόlya’s theorem and the Möbius inversion method together with generalized character cycle…
Over the past 60 years, the use of crystals to define structures of complexes using X-ray analysis has contributed to the discovery of new medicines in a very significant way. This has been in understanding not only small-molecule inhibitors of proteins, such as enzymes, but also protein or peptide hormones or growth…
Abstract Phosphorescent dopants are promising candidates for organic light‐emitting diodes (OLEDs). Although it has been established that the out‐coupling efficiency and overall performances of vacuum‐deposited OLEDs can be significantly improved by a horizontal orientation of the dopants, no horizontally oriented gol…
Purpose: This study aimed to evaluate the role of magnetic liposome nanoparticles (ML NPs) as a carrier for paclitaxel (PTX) for the treatment of ovarian cancer in vitro. Methods: Magnetic NPs (MNPs) were synthesized by chemical co-precipitation method. The resulting NPs were characterized in terms of size, size distr…
In this study, pre-deformation followed by heat treatment for enhancing the formability of AZ31-0.5Ca magnesium alloy was investigated. For this purpose, alloy samples were subjected to tensile deformation at various amounts of strains (5%, 10%, and 15%) followed by heat treatment at 260°C for 30 min. The results show…
This article deals with the effect of residual stresses on the fatigue behaviour of torsion bars exposed to cyclic torsional loading with different effective loading ratios, R. The residual compressive stresses on the surface were induced during technological processes by cold surface rolling and torsional overloading…
We measure the birefringence of the nonlinear optical (NLO) properties of cadmium silicon phosphide via the Z-scan technique at near and mid-infrared wavelengths. We discuss the implications of the NLO properties on optical parametric amplifier performance. We find that the nonlinear absorption does reduce the convers…
Lenses with two or more foci along the longitudinal direction exhibit immense potential in several optical applications. In this study, we propose an approach for generating subdiffraction longitudinal bifoci by binary-phase bifocal super-oscillatory lenses (SOLs), which are realized by simple AND operation between tw…
Abstract The binary alloy Mn 0.5+x Bi 0.5−x , x ⩽ 0.05, is a promising rare-earth-free magnetic material, with high-energy-density (a critical characteristic for electric motors and power electronics), low cost, and significant magnetic properties for multiple uses at room temperature. In this article, we report how a…
Abstract This report demonstrates the visible photo response of gold nanoparticles (AuNPs) embedded ZnO nanocomposite (AuNPs-ZnO) thin films. The AuNPs-ZnO films were prepared by sandwiching DC sputtered AuNPs in between two RF sputtered ZnO layers deposited on p-Si. Crystal phase purity and surface morphology were ch…
In this work, the structural, electronic and absorption properties of 2-methyl-2H-naphtho-[1,8-de]triazine in the pressure ranges of 0–250[Formula: see text]GPa are studied in detail (hereinafter referred to as 2-methyl crystal). Density functional theory (DFT) is used to calculate the lattice constants, bond lengths…
The effects of an axial static magnetic field on surface and bulk plasmons of a cylindrical electric-gyrotropic (or ε -anisotropic) wire are investigated. Solving a modified Laplace’s equation in conjunction with the appropriate boundary conditions, the dispersion relations, power flows, energy densities, and group ve…
Abstract To recapitulate the heterogeneous complexity of tissues in the human body with synthetic mimics of the extracellular matrix (ECM), it is important to develop methods that can easily allow the selective functionalization of defined spatial domains. Here, a facile method is introduced to functionalize microfibr…
AISI D2 steels are an interesting family of tool steels that generally have applications in knife blades, shaper blades, and forging and punching dies due to its optimum toughness, lower wear rate, and relatively high hardness. The present research work aims to design a new heat treatment cycle consisting of single te…
