Due to a significant increase in the demand for usable power, research focused on energy-material relations has garnered considerable attention. Fuel cells, characterized by their high efficiency, high energy density, quiet operation, and environmental friendliness, are regarded as a promising future power source that provides clean power at the point of use. The incorporation of […]
Chemical bath deposition (CBD) was used to prepare titanium dioxide (TiO2) nanocrystalline thin films on glass substrates. The TiO2 nanocrystalline thin films were created, and the Scanning Electron Microscope (SEM) images showed that they developed as nanoflowers and tiny semi-nanoplate bundles that grew vertically onto the surface of the substrates with uniform distribution. The nanoplate […]
A novel organic-inorganic hybrid magnetic nanomaterial, namely nano-[Fe3O4@SiO2@R-NMe2][FeCl4] (nano-[FSRN][FeCl4]) was prepared, and characterized by EDX, elemental mapping, FE-SEM, FT-IR, XRD, VSM, TG and DTG analyses. Then, it was applied as a highly efficient and magnetically recyclable catalyst for the solvent-free synthesis of bis-coumarins from 4-hydroxycoumarin (2 eq.) and arylaldehydes (1 eq.). NMe2 is a basic […]
A highly efficient, eco-friendly procedure has been proposed for the synthesis of 2-amino-3-phenylsulfonyl-4H-pyran derivatives via nano-cellulose-OSnCl4-x catalyst prepared from cotton as support treated with tin tetrachloride (SnCl4). This catalyst is characterized by FT-IR, FESEM, TEM, TGA, and EDX. The TEM results confirmed the size of the nano-cellulose-OSnCl4-x catalyst was below 30 nm. The efficiency of […]
This study investigates the effect of a combination of copper and magnesium oxide nanoparticles embedded in a Polyvinyl chloride (PVC) matrix on photocatalytic activity. A thin film of CuO/MgO/PVC nanocomposites (NCs) was synthesized using the sol-gel route. Different weight percentages of CuO/MgO nanocomposites (5% and 15%) incorporated in the PVC matrix were deposited on glass […]
In this study, we synthesized ethyl levulinate (EL) by alcoholysis of furfuryl alcohol (FAL) with ethanol using two catalysts, SBA-15-SO3H (SHS-15) and SBA-16-SO3H (SHS-16). The catalysts were prepared through the hydrothermal method, and their physical and chemical properties were assessed using various techniques such as small and wide-angle XRD, N2-sorption, SEM, TEM, FTIR, and Py-FTIR. […]
In this work, the Response Surface Methodology (RSM) was investigated by applying the Design of the Experiment in normal heptane isomerization. The design was guided to three surface responses on the dependency of normal heptane conversion, isomerization selectivity, and research octane number on the reaction temperature (200 – 350 °C), the weight percentage of protonated […]
The current research work was mainly focused on the antibacterial performance of Mn/Mg co-doped TiO2 nanoparticles in presence of Gemini surfactant (GS). Mn, Mg co-doped TiO2 nanoparticles were synthesized by sol-gel method and calcined at 450 0C. The characterization results reveal that among all the co-doped TiO2 and surfactant encapsulated TiO2 nanoparticles, the MMT5-GS2 Nano […]
ZnO nano particles and Cu modified ZnO nano composites have been prepared by simple, facile hydrothermal approach. The novelty of this work was the use of aqueous methanolic solution (50:50 ratio) as the solvent of reaction, while zinc chloride was used as the precursor of ZnO NPs and Cu- modified ZnO nano composites. XRD results […]
Densely functionalized 3,4-dihydropyridones were synthesized by a four-component reaction of Meldrumʼs acid, ethyl acetoacetate, ammonium acetate, and proper aromatic aldehydes in the presence of novel organic-inorganic cobalt incorporated magnetic nanocatalyst (γ-Fe2O3@HAp/Co(II)) using ethanol as a green solvent at reflux condition. This new synthetic method provided the target compounds in a high yield (70-95%) and lower […]
