It is our great honor and privilege to present this Special Issue on ``Chemistry of Nanomaterials: Synthesis, Characterization and Applications'' in the Sultan Qaboos titled University Journal for Science (SQUJS). This thematic collection showcases research that highlights the important role of nanomaterials in addressing contemporary scientific, technological, environmental, and biomedical…
In recent times, investigators have conducted extensive studies on carbon nitride-based photocatalytic materials. Earlier research mainly concentrated on the poly-condensation technique and the uses of the produced materials, whereas less attention was given to the starting precursors, which were broadly classified as nitrogen-rich. This research offers a complete examination of the appropriate…
In this study, we report the successful synthesis of solid solution (SS) cerium bismuth oxide (CBO) photocatalysts via a facile combustion method using urea as starting materials at different calcination temperatures (300–900°C). The prepared CBO exhibited a nanocrystalline fluorite structure with a direct band gap of 3.02 eV, enabling efficient visible light driven photocatalytic water splitting.…
The rapid increase in anthropogenic carbon dioxide (CO2) emissions and the growing global energy demand have intensified the search for sustainable carbon mitigation and clean energy solutions. Nanomaterials have emerged as promising candidates for carbon capture, energy conversion, and storage technologies due to their high surface area, tunable physicochemical properties, and superior catalytic…
The growing demand for safe and controlled application of medicines in biological field has led to the development of using synthetic polymers. Essential oils have been used as green insecticides due to their non-toxic and eco-friendly nature. In this study, a green alternative insecticide based on PVA polymeric nanofibers and lemongrass was successfully prepared using electrospinning technique…
The interfacial adhesion between polymer coatings and oxide substrates is a critical issue to improve the durability of the protective systems used in aggressive environments. Despite extensive research on polymer coatings, the atomistic understanding of the temperature-dependent adhesion behavior of polyurea on silica (SiO2) surfaces remains limited. In this study, the adhesion behavior of…
Graphene offers tremendous potential for applications in biomedical and pharmaceutical areas, ranging from molecular diagnostics, biosensors, and prosthetics to implants and drug delivery. However, realising the full potential of graphene is blocked by a limited understanding of the nature and detail of its noncovalent interactions with biological molecules in aqueous dispersion, where such…
Serious health issues, including cancer, redness, skin irritation, and allergic reactions, have been linked to factories releasing Congo red dye into water supplies. Therefore, this study focused on the simple production of NiO/CoO (NCO) metal oxide nanocomposites using the reflux-assisted chemical precipitation method. Subsequently, these metal oxide nanocomposites were employed for effective…
Nanotechnology is essential in many scientific disciplines, particularly materials science, where titanium dioxide (TiO2) nanoparticles are widely studied for their stability and high photocatalytic performance in environmental applications. This study reports the green synthesis of TiO2 nanoparticles using Clitoria ternatea (butterfly pea) flower extract as a natural reducing and stabilizing…
Rising need for quality orthopedic plate implants requires more efficient and sustainable manufacturing techniques. Traditional manufacturing routes for these implants includes gravity casting, forging, and powder metallurgy. Such methods often suffer from limitations such as non-uniform microstructures, high energy consumption, prolonged processing times, and environmental concern.…
