dehydration method by modifies the commercial MgO. The prepared MgO had been investigated as a heterogeneous base catalyst for transesterification process for biodiesel production using palm oil. TGA, FT-IR and XRD results obtained from this study lie each other and proved in the formation of nano MgO from decomposition of Mg(OH) 2. This study proved that the prepared nano MgO was a better base...

The perpendicular magnetic anisotropy (PMA) of Fe1-x Co x thin films on MgO(001) was investigated via first-principles density-functional calculations. Four different configurations were considered based on their ground states: Fe/MgO, Fe12Co4/MgO, Fe10Co6/MgO, and Fe8Co8/MgO. As the Co composition increases, the amplitude of PMA increases first from Fe/MgO to Fe12Co4/MgO, and then decreases in...

Aims: To study the effect of metal oxide nanoparticles (MgO, ZrO2, ZnO) on acrylic based soft liner surface properties and FTIR. Materials Methods: Acrylic-based soft-liner specimens were prepared by adding three different concentrations (0.5, 1, 2) %wt ZnO). A disk-shaped with 30mm diameter 3mm thickness for shore (A) hardness test to evaluate modified liner. The roughness samples (10X10X2mm) ...

Abstract The article explores the three-dimensional stream of silver (Ag), magnesium oxide (MgO), and motile microorganism water-based hybrid nanofluids as independent time through a circular cylinder with sinusoidal radius. goal this research is to optimize rate energy mass transfer having periodic phenomena are simulated system partial differential equations containing momentum, temperature, ...

A novel magnetic functionalized material based on graphene oxide and nanoparticles (MGO) was used to develop a solid phase extraction method (MSPE) enrich both, inorganic organic arsenic species in environmental waters biological samples. An automatic flow injection (FI) system preconcentrate the simultaneously, while ultra-trace separation determination of arsenobetaine (AsBet), cacodylate, As...

Preserved eggs are prone to lose water during storage, which causes the preserved shrink and have poor taste, bad flavor, reduced quality. By studying a degradable coating agent applying it eggs, we explored its effect on quality of storage. In this paper, structure performance gelatin film (GF), gelatin–bacterial cellulose (GBF), cellulose–MgO nanocomposite (GBMF) were by adding bacterial (BC)...

Abstract Nanofluid flooding has become one of the advantageous enhanced oil recovery (EOR) techniques due to transcendental property nanoparticle. Nanoparticles with various morphology presents different effects and mechanisms EOR. To provide some guidance on selection nanomaterials for flooding, 4 kinds nanomaterials, including silicon dioxide (SiO 2 ), magnesium oxide (MgO), graphene (GO) mol...

The aim of this study was to investigate the histopathological changes in zebrafish larvae following embryonic exposure to nanoparticles of magnesium oxide (MgONPs). The toxicity of metal oxide nanoparticles is attracting increasing attention. Among these nanomaterials, MgONPs are particularly interesting as a low cost and environmentally-friendly material. Histological investigations are used ...

The control of the magnetization inversion dynamics is one main challenges driving design new nanostructured magnetic materials for magnetoelectronic applications. Nanoparticles with onion-like architecture offer a unique opportunity to expand possibilities allowing combine different phases at nanoscale and also modulate coupling between by introducing spacers in same structure. Here we report ...

This work reveals a sol–gel approach for synthesis of silver doped magnesium oxide (Ag:MgO) incorporated in PVC matrix to give Ag:MgO/PVC nanocomposite. On glass substrate three different percentages (3,7, and 10%) were deposited by spin coating method. film nanocomposites characterized using AFM, UV–Vis, XRD FTIR analysis. The results revealed the formation Ag MgO nanoparticles with two phases...
