Estuarine and marine sediments are a probable end point for many engineered nanoparticles (ENPs) due to enhanced aggregation and sedimentation in marine waters, as well as uptake and deposition by suspension-feeding organisms on the seafloor. Benthic infaunal organisms living in sediments encounter relatively high concentrations of pollutants and may also suffer toxic effects of ENPs. We tested...

Stable suspensions of NiO and Mn₃O₄ nanoparticles (NPs) with a mean (±s.d.) diameter of 16.7±8.2 and 18.4±5.4 nm, respectively, purposefully prepared by laser ablation of 99.99% pure nickel or manganese in de-ionized water, were repeatedly injected intraperitoneally (IP) to rats at a dose of 2.5 mg/kg 3 times a week up to 18 injections, either alone or in combination. A group of rats was inject...

Abstract Over the past several years, greener fabrication of metal oxide nanoparticles has attracted significant attention due to their simplicity, eco-friendliness, availability, and nontoxicity. This paper focused on nickel (NiO-NPs) using leaf extract Ziziphus spina-christi L. evaluating its potential biological activities. The characterization synthesized NiO-NPs was confirmed ultraviolet–v...

In this study, we synthesized a powder consisting of core-shell-structured Ni/NiO nanocluster-decorated graphene (Ni/NiO-graphene) by a simple process for use as an anodic material for lithium-ion batteries. First, a crumpled graphene powder consisting of uniformly distributed Ni nanoclusters was prepared by one-pot spray pyrolysis. This powder was subsequently transformed into the Ni/NiO-graph...

In this work, nickel oxide nanoparticles-modified multi-walled carbon nanotubes (CNTs) were prepared and used for H2O2 sensing application. Firstly, ex situ NiO nanoparticles (NPs) further to decorate polyethylenimine (PEI)-modified carboxylated CNTs. The obtained nanocomposite its precursors identified by using X-ray diffraction, thermal analysis, Raman spectroscopy SEM TEM images, N2 adsorpti...

Different concentrations of nickel oxide (NiO) nanoparticles were successfully inserted into polystyrene (PS) polymer matrix using the solution casting method. X-ray diffraction (XRD), Fourier transform infrared (FT-IR), High-resolution scanning electron microscope (HRSEM), and UV–Vis techniques are used to characterize nanocomposites. XRD, HRSEM, FT-IR results indicate that PS NiO have a good ...
