Density functional theory (DFT) approach was employed to investigate relaxation processes of each of pyrimidine nucleobases (NBs); cytosine (C), thymine (T) and uracil (U), at the Cubane Cluster Surface (CCS). The main idea was about providing a material for recognition of NBs, in which a nanostructure form of cubane (CCS) was first generated by optimization […]
In this work, the quantum mechanics calculations were carried out to elucidate the adsorption behavior of some corticosteroid drugs (clobetasol, beclometasone, prednisolone, and methylprednisolone) on the surface of C60 nano-fullerene using density functional theory (DFT) at B3LYP/6-31G (d,p) level. After optimization of the structures, various parameters such as HOMO and LUMO energies, energy gap, adsorption […]
In this study, an inverse trigonometric nanobeam theory is applied for the bending, buckling, and free vibration analysis of nanobeams using Eringen’s nonlocal theory. The present theory satisfies zero shear stress conditions at the top and bottom surfaces of the nanobeam using constitutive relations. Equations of motion are derived by applying Hamilton’s principle. The present […]
The seed extract of Spondia mombins was used in the biofabrication of silver nanoparticles (AgNPs) in this study. The biosynthesized AgNPs was characterised using UV-Vis Spectroscopy, FTIR, FESEM, TEM, XRD and EDX. The antimicrobial efficacy of the synthetized AgNPs was evaluated against certain pathogens. The absorption spectrum peaked at 425 nm when the UV analysis […]
Metallic nanoparticles synthesised via green synthetic route have been proved to be detrimental against pathogens. An attempt was made to synthesise copper nanoparticles (EcS-Cu NPs) using the root extract of Echinops sp., Ethiopian medicinal plant. The most advanced techniques were employed to characterize the NPs. The presence of absorbance maxima, λmax at 454 nm confirms […]
Thanks to their outstanding advantages, nanostructured lipid carriers (NLCs) have recognized in various fields these days. One way to discover extra useful products against typical bacteria (e.g., Staphylococcus epidermidis) is NLCs loaded with essential oils. This paper aims to provide NLCs to encapsulate MA oil and characterize and survey the obtained MA oil-loaded NLCs on […]
It was shown that the structure and particle size of zirconia nanoparticles has been controlled through the homogeneous precipitation process by using templates. Hexamine as the template led to ZrO2 nanoparticles with tetragonal structure, whereas coffee extract favored monoclinic structures. Field Emission Scanning electron microscopy (FeSEM), Transmission electron microscopy (TEM) measurements, Infrared and Raman analysis […]
In this paper, MgAl2O4 nanoparticles were synthesized by the Sol-gel auto combustion method and were doped with different concentrations of Ni2+ (x= 0, 0.1, 0.05, and 0.03). By this method, a novel photocatalyst which had better decolorization percentages of Congo redcompared to MgAl2O4 was produced. The MgAl2O4 samples were calcinated at 1000 0C. The samples […]
Tin oxide (SnO2)nanoparticles were synthesized by co-precipitation method and the synthesized nanoparticles were annealed at different temperatures for characterization. The powders were investigated with X-ray diffraction, scanning electron microscopy and optical spectroscopy. The structural characterization was carried out by X-ray diffraction which confirms the crystalline nature of the films with a tetragonal structure. SEM analysis […]
The design and optimization of nanostructure-based surface acoustic wave (SAW) gas sensor is analyzed based on TiO2 sensing layer and modified electrode dimensions. The sensitivity of the gas sensor depends upon the type of sensing layer used and active surface area obtained by varying the aspect ratio. The performance of the sensor is observed from […]
