Absorbed hydrogen can dramatically increase hydrogenation activity of Pd nanoparticles and was predicted to do so also for Pt. This calls for investigations of the energetic stability of absorbed H in Pd and Pt using nanoparticle models as realistic as possible, i.e., (i) sufficiently large, (ii) supported, and (iii) precovered by hydrogen. Herein, hydrogen absorption is studied in MgO(100)-sup...

Photocatalytic water splitting has greatly stimulated as an ideal technique for producing hydrogen (H$_{2}$) fuel by employing two renewable sources, i.e., and solar energy. Here, we have adopted a facile hydrothermal approach the successful synthesis of reduced graphene oxide (rGO) incorporated Fe/MgO nanocomposites followed thermal treatment at inert atmosphere to investigate their ability ph...

Effects of magnetic hydroethanolic extract Nigella sativa and magnesium oxide nanoparticles (MgO) on catalase gene expression in liver diabetic male rats

Extensive use of nanoparticles (NPs) in consumer and industrial products has led to concerns about their potential environmental impacts; however, the influences of different NPs (e.g., nZVI (nano zero-valent iron), Ag NPs, Fe2O3 NPs and MgO NPs) on the anaerobic digestion of sludge have not yet been studied in depth. Additionally, a new guideline or the use of different NPs in the anaerobic di...

Nanotechnology is a rapidly growing field of science and technology that deals with the development new solutions by understanding controlling matter at nanoscale. Since last decade, magnesium oxide nanoparticles (MgO-NPs) have gained tremendous attention because their unique characteristics diverse applications in materials sciences they are non-toxic relatively cheaply available materials. Mg...

introduction: our previous study has showed that chronic administration of magnesium oxide nanoparticles (mgo np) can reduce anxiety in adult male rat. in this study the effects of mgo np on anxiety induced by morphine withdrawal were investigated in adult male mice. methods: adult male nmri mice (weighing 27 ± 3 g) divided into groups: control, receiving intraperitoneal (i.p.) injection of mgo...

Abstract Magnesium oxide (MgO) nanoparticles' biocompatibility and degraded by-products are the two most important factors that make this material preferable in dental care. Their specific characteristics, such as antibacterial action against cariogenic microbes, potential agents for applications. This paper investigates properties of MgO dentistry sets groundwork future research. Electronic da...

conclusions according to the results, cop is an efficient and rapid method for removing of toluene from aqueous solutions. results the analysis of variance (anova) of the toluene degradation by cop/mgo nanoparticles showed f-value of 19.53 for the quadratic model indicating that the prepared model is significant. the predicted result showed that maximum degradation of toluene (~99.99%) could be...

This work described one pot syntheses of polysubstituted 2,6- dicyanoaniline and 2-(3-Oxo-1,3-diarylpropyl) malononitrile derivatives in the presence of MgO nanoparticles (NPs) under grinding conditions and microwave irradiation, respectively. The simple experimental procedure includes shorter reaction times, higher yields, lower cost and environmental friendliness. Other remarkable features ar...

We use ev GW /BSE calculations to demonstrate that the optical and electronic properties of MgO nanoparticles are governed by low-coordinated atoms on their surfaces.
