In this paper, graphene oxide decorated with cerium oxide (CeO2) nanoparticles was prepared and used as anticorrosive pigments in epoxy nanocomposite coatings. The synthesized nanoparticle was characterized by FTIR, XRD, SEM, and EDX analyses. Graphene oxide decorated with CeO2 nanoparticles was dispersed in epoxy resin by sonication. The optimum nanoparticle content of th...
Abstract Rare earth metal cerium-doped titania nanoparticles (titanium dioxide [TiO 2 ]) were produced utilizing a low-cost and straightforward sol–gel technique, its enhanced photodynamic anticancer activity was tested on Y79 retinoblastoma cancer cells. The structural, optical, morphological, activity, cytotoxicity of pure TiO (Ce-doped ) investigated. In X-ray diffraction (XRD) measurements,...
More than 100 million tonnes of municipal solid waste are incinerated worldwide every year. However, little is known about the fate of nanomaterials during incineration, even though the presence of engineered nanoparticles in waste is expected to grow. Here, we show that cerium oxide nanoparticles introduced into a full-scale waste incineration plant bind loosely to solid residues from the comb...
In the present work, we have investigated synthesis of cerium oxide nanoparticles (CeO2 NPs) using Curvularia lunata culture filtrate. The synthesized CeO2 NPs were characterized by TG/DTA, XRD, Raman, PL, FTIR, UV-visible spectroscopy and TEM analyses. The synthesized nanoparticles retained the cubic structure, which was confirmed by X-ray diffraction studies. UV-visible spectrum exhibited a w...
This paper investigates a nano-enhanced wireless sensing framework for dissolved oxygen (DO). The system integrates a nanosensor that employs cerium oxide (ceria) nanoparticles to monitor the concentration of DO in aqueous media via optical fluorescence quenching. We propose a comprehensive sensing framework with the nanosensor equipped with a digital interface where the sensor output is digiti...
Cerium dioxide (CeO2) and silicon dioxide (SiO2) nanoparticles are of widespread use in modern life. This means that human beings are markedly exposed to them in their everyday life. Once passing biological barriers, these nanoparticles are expected to interact with endothelial cells, leading to systemic alterations with distinct influences on human health. In the present study we observed the ...
Background Cerium oxide (CeO2) is a technologically important material due to its properties and applications in several areas that range from engineering to biological sciences. Despite the hydrothermal microwave method versatility, its crystallization kinetics has low speed when the processing temperatures are below 300°C which are the desired conditions for soft chemistry processes [1,2]. At...
