Abstract The depreciation of assets and safety threats because corrosion has forced to develop eco-friendly smarter protection strategies. In this study, natural Gum Arabic (GA) was used as a inhibitor loaded into cerium oxide nanoparticles (CONPs) an environment-friendly additive for coated steel in the marine environment. This uniformly dispersed epoxy formulation that protect plates. Epoxy c...

Abstract At present, no effective treatment exists for the clinical toxicity of cobalt nanoparticles (CoNPs, 30 nm) after metal-on-metal (MOM) artificial joint replacement. As such, a better understanding CoNPs-toxicity mechanism is necessary and urgent development safe detoxification drugs. Our purpose was to explore role bioactive nano-selenium (BNS, > 97%) in antagonizing CoNPs its throug...

Background: The present study aimed to evaluate the effects of different concentrations of cerium oxide nanoparticles (CONPs) on the oxidative stress (OS) status in kidney, lung, and serum of rats. Methods: Male Wistar Rats were treated intraperitoneally with 15, 30, and 60 mg/kg/day of CONPs. The biochemical parameters, including total antioxidant capacity (TAC), total thiol group (TTG), malon...

We report the synthesis of cobalt nanoparticles supported on nitrogen-doped carbon (CoNPs@N/C), which can reduce O2 into H2O2 with high selectivity (up to 93%) in 0.1 M KOH electrolyte and retains ...

Covalent organic frameworks (COFs) are a new class of porous crystalline polymers, which considered to be excellent supports for metal nanoparticles (MNPs) due their highly ordered structure, chemical tunability, and porosity. In this work, two novel ultra-microporous COFs, JUC−624 JUC−625, with narrow pore size distribution have been synthesized used the confined growth ultrafine Co (CoNPs) hi...

Cervical carcinoma is one of the main causes of women's cancer, and substantial side effects from standard treatment including platinum-based chemotherapy limit the options for escalation. In this paper, using cervical cancer cell lines and tumor-bearing mice as models, we report that CONPs could inhibit the proliferation of cancer cells in vitro and in vivo. Especially CONPs could inhibit tumo...

The paper reports on the charge transport in sandwich-like graphene / Co nanoparticles structure (G/CoNPs/G). It is fabricated by combining electrochemical deposition of onto a single layer CVD and their capping with another layer. isolated semi-spherical, surface oxidized NPs 250 nm diameter serve as support for top provide its suspended state confirmed atomic force microscopy revealing period...

For the synthesis of Cobalt Nanoparticles (CoNPs), prudent wet phase reduction process was applied by employing urea as an effective oxidizing agent. The requirement analogous precipitation executed method fulfilled taking advantage sufficiently slow hydrolysis in water at acceptable temperature. experiment carried out mixing cobalt nitrate and (1:2) distilled water. reaction mass then subjecte...

Introduction: Recently Cerium oxide nanoparticles (CONPs) are being checked as interventional treatments in biological systems. The scavenging of free radicals by nanoparticles performance is the inhibition of Reactive Oxygen Species (ROS). Ionizing radiations can prevent the proliferation and differentiation of cells and even cause apoptosis. CONPs, as radioprotection, can pro...

A series of small and well defined cobalt nanoparticles were synthesized by the chemical reduction of cobalt salts in water using NaBH4 as a reducing agent and using various polymeric stabilizers. The obtained nanocatalysts of similar mean diameters (ca. 2.6 nm) were fully characterized and tested in the aqueous phase Fischer-Tropsch Synthesis (AFTS). Interestingly, the nature and structure of ...
