Green chemistry is the pragmatism of a set of principles, which eliminate the use or production of hazardous substances in the design, development, synthesis and applications of chemical harvest. Accordingly, green synthetic techniques aim at hazard reduction as the recital criteria, whilst designing new chemical processes/methods. Catalysis lies at the heart of all chemical processes […]
In this article, the high-k gate dielectric effect on the operation of complementary metal oxide semiconductor (CMOS) inverter build using conventional (CL) double-gate (DG) metal oxide semiconductor field effect transistor (MOSFET) and junctionless (JL) double-gate (DG) MOSFET has been explored. It is found that the improvement in inverter performance is more pronounced in CL-DG-MOSFET based […]
This article reports an experimental study of heat transfer characteristics of multi-walled carbon nanotubes (MWCNTs). These nanofluids, consisting of water with different weight concentrations of nanofluid (0.0.1–0.145% wt.), have flown in counter flow plate heat exchanger under turbulent conditions (the range of Reynolds numbers 2500-6500) for cooling applications. The nanofluid was prepared by dispersing MWCNT […]
In this study, a new and effective catalyst was prepared by supporting the α-Fe2O3 nanoparticles on a metal-organic framework (MOF). The synthesis of nano α-Fe2O3 photocatalyst was performed according to the reflux condensation method. The MOF was synthesized using cadmium nitrate and terephthalic acid. The nano α-Fe2O3 stabilized on the MOF by the solid-state distribution […]
This study investigates the possible effects of iron oxide nanoparticles (FeNPs) on plant growth, expression of bZIP, DREB, and WRKY1, and biofortification efficacy in wheat (Triticum aestivum). The seedlings were treated with bulk iron oxide (bulk-Fe) or FeNPs at 100, 200, 300, and 400 mgL-1. FeNPs significantly improved the fresh and dry weights of shoot […]
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 […]
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 […]
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 […]
