In the present paper, a refined trigonometric higher-order shear deformation theory has been presented with conjunction of nonlocal for vibrational response functionally graded (FG) porous nanoplate. The displacement field is chosen based on assumptions that out plane consists bending and components whereas transverse shear-strain nonlinear variation along thickness direction. number unknown variables four, as against five in other renowned theories. governing equations have derived using...
Rapid industrialization and untreated industrial effluents loaded with toxic carcinogenic contaminants, especially dyes that discharge into environmental waters, have led to a rise in water pollution, substantial adverse impact on marine life humankind. Photocatalytic techniques are one of the most successful methods help degradation and/or removal such contaminants. In recent years, semiconductor quantum dots being substituted by carbon (CDs) as photocatalysts, due ease formation,...
In this paper, systematic study of structural, vibrational, and optical properties undoped 1-10 at.% Fe doped ZnO nanostructures, synthesized adopting chemical precipitation route, has been reported. Prepared nanostructures were characterized employing an assortment microscopic spectroscopic techniques, namely Scanning Electron Microscopy (SEM), Transmission (TEM), Energy Dispersive X-ray (EDX) Spectroscopy, Diffraction (XRD), Fourier Transform Infrared (FTIR), Micro-Raman Spectroscopy...
Introduction: Stroke is the third-leading cause of death. Carotid artery stenosis (CAS) accounts for 8%–37% strokes. Landmark carotid trials have shown endarterectomy (CEA) superior to best medical therapy (BMT) symptomatic moderate and asymptomatic high-grade stenosis. This study aims correlate imaging characteristics vulnerable plaque (VP) with clinical histopathological features assess ability artificial intelligence (AI) techniques identify VP disease burden using duplex ultrasound (DU)...
Preliminary results on the fabrication of a memristive device made zinc oxide (ZnO) over mesoporous silicon substrate have been reported. Porous (PS) is employed as template to increase formation oxygen vacancies in ZnO layer and promote suitable grain size conditions for memristance. Morphological optical properties are investigated using scanning electron microscopy (SEM) photoluminescence (PL) spectroscopy. The proposed exhibits zero-crossing pinched hysteresis current-voltage (I-V) curve...
Abstract Morphological and optical characteristics of radio frequency-sputtered zinc aluminum oxide over porous silicon (PS) substrates were studied before after irradiating composite films with 130 MeV nickel ions at different fluences varying from 1 × 10 12 to 3 13 ions/cm 2 . The effect irradiation on the structure was investigated by scanning electron microscopy, X-ray diffraction (XRD), photoluminescence (PL), cathodoluminescence spectroscopy. Current–voltage ZnO-PS heterojunctions also...
Eu doping concentration driven effect on the morphological, electrical, and optical properties of ZnO films prepared by sol gel method have been studied systematically. The were using various experimental tools such as XRD, AFM, XPS, photoconductivity, UV–vis spectroscopy, photoluminescence (PL), photocatalytic activity. incorporation into lattice was confirmed XPS analysis. A decrease in crystallite size with increasing observed. PL spectra showed that Eu‐ related light emission intensity...
Abstract The increasing use of nanomaterials in consumer products is expected to lead environmental contamination sometime soon. As water pollution a pressing issue that threatens human survival and impedes the promotion health, search for adsorbents removing newly identified contaminants from has become topic intensive research. challenges recyclability contaminated continue campaign development highly reusable catalysts. Although exfoliated 2D MXene sheets have demonstrated capability...
