Retracted: Study of the wettability of ZnO nanofilms

This article was mistakenly published twice. For this reason this duplicate article has now been retracted. For citation purposes please cite the original:http://​www.​inljournal.​com/​?​_​action=​articleInfo&​article=​21 Abstract Al-doped and un-doped ZnO thin films deposited on quartz substrates by the nebulized spray pyrolysis method were studied to investigate the wettability...

Retracted: Optimization of radiation modes in asymmetric planar slab optical waveguides

This article was mistakenly published twice. For this reason this duplicate article has now been retracted. For citation purposes please cite the original:http://​www.​inljournal.​com/​?​_​action=​articleInfo&​article=​17 Abstract In this paper, we try to optimize the substrate-radiation/substrate-cladding (cover) radiation modes in terms of their performance parameters. It is...

Realistic confinement potential for a square-patterned two-dimensional semiconductor quantum dot and its approximated circular counterpart

Two-dimensional semiconductor quantum-dot systems are typical nanoscale structures in which a few number of electrons is confined in a small region of space by applying external electric gate potentials. While the detailed form of the confining potential depends on the specific experimental setup, the parabolic confinement model has commonly been used because of its simplicity...

Optimization of synthesis and characterization of nanosilica produced from rice husk (a common waste material)

Rice husk (RH), an inexpensive waste material, was used to produce nanosilica. Acid treatment of RH followed by thermal combustion under controlled conditions gave 22.50% ash of which 90.469% was silica. Various chemical treatments in varied conditions for controlled combustion were investigated in order to produce highly purified nanosilica. The structural properties (such as X...

Influence of Cr3+ substitution on the electrical and magnetic properties of Ni0.4Cu0.4Zn0.2Fe2O4 nanoparticles

The Ni0.4Cu0.2Zn0.4 ferrites with different concentrations of Cr3+ were synthesized at a low temperature (450°C) using sol–gel auto-combustion method. The X-ray diffraction analysis of the samples confirms the formation of a single-phase cubic spinel structure. The lattice constant decreases from 8.331 to 8.253 Å with an increase in Cr3+ substitution. Bulk density decreases from...

Unsteady MHD free convection boundary-layer flow of a nanofluid along a stretching sheet with thermal radiation and viscous dissipation effects

In this work, we study the unsteady free convection boundary-layer flow of a nanofluid along a stretching sheet with thermal radiation in the presence of magnetic field. To obtain non-similar equations, continuity, momentum, energy, and concentration equations have been non-dimensionalized by usual transformation. The non-similar solutions are considered here which depend on the...

Geometrical parameters measurement of surface functionalized micromachined micro-cantilever using optical method

Micro-cantilever arrays with different dimensions are fabricated by micromachining technique onto silicon <1 0 0> substrate. These sputtered gold-coated micro-cantilevers were later surface-functionalized. Scanning electron microscopy (SEM), atomic force microscopy (AFM), and optical diffraction with laser source are employed to characterize the morphology and image measurement...

Study of bactericidal properties of carbohydrate-stabilized platinum oxide nanoparticles

Platinum oxide nanoparticles were prepared by a simple hydrothermal route and chemical reduction using carbohydrates (fructose and sucrose) as the reducing and stabilizing agents. In comparison with other metals, platinum oxide has less environmental pollution. Therefore, Pt is considered an appropriate candidate to deal with environmental pathogens. The crystallite size of these...

Tailored hybrid hyperbranched polyglycidol-silica nanocomposites with high third-order nonlinearity

One of the most convenient techniques for optical material fabrication is the sol–gel processing. It can be performed at low temperature that enables one to entrap even relatively unstable organic substances into silica matrix at the nanometer scale, thus developing homogeneous hybrid organic–inorganic nanocomposite materials of various functionalities. Here, novel hybrid organic...

Retracted: Structural, electrical, and optical properties of ATO thin films fabricated by dip coating method

Antimony-doped tin oxide (ATO) thin films were prepared by dip coating method. The effect of antimony doping on the structural, electrical, and optical properties of tin oxide thin films were investigated. Tin(II) chloride dehydrate (SnCl2·4H2O) and antimony(III) chloride (SbCl3) were used as a host and a dopant precursor, respectively. X-ray diffraction analysis showed that the...

Bismuth(III) salophen as a new catalyst has been synthesized. Structural properties of this complex have been studied by Fourier transform infrared spectroscopy, X-ray diffraction, differential scanning calorimetry, and thermal gravimetric analyses. The average crystalline size of Bi-salophen particles was 86 nm. Thermal analyses show that the complex is stable over 300°C...

Retracted: Effect of sintering temperature on apparent density and transport properties of NiFe2O4: synthesized from nanosize powder of NiO and Fe2O3

Polycrystalline NiFe2O4 was prepared by solid-state reaction from nanosize powders of NiO and Fe2O3 which were synthesized by wet chemical method. Enhancement of apparent density of the sample has been observed with the increase in sintering temperature and has great influence on the transport properties of NiFe2O4. Decrease in resistivity with increasing temperature confirms the...
