Doping of simple oxide materials can give rise to new exciting physical and chemical properties and open new perspectives for a variety of possible applications. Here we use density functional theory calculations to investigate the B-, C- and N-doped MgO(001) surfaces. We have found that the investigated dopants induce magnetization of the system amounting to 3, 2 and 1 μB for B, C and N, respe...

In order to improve the corrosion resistance of aluminosilicate refractories by molten aluminum, alkaline fluoride NaF and cryolite Na3AlF6 powders were studied. Both physical and chemical properties are known to influence wetting and corrosion behavior. This paper devoted to determine the influence of alkaline fluoride and cryolite added to andalusite based castable on the reaction with a...

objective(s): our previous studies have shown that mgo nanoparticles (mgo nps) could improve anxiety and reduce pain in animals. in this study, the effect of co administration mgo nps and vitamin c on anxiety like behavior and nociception in postpartum depression (ppd) model were investigated.materials and methods:  female mice (27 ± 3 g) were divided into groups: two control groups, ppd groups...

The effect of aging temperature on discharge characteristics of the MgO film of alternating currentplasma display panels (AC-PDPs) has been investigated from the point of view of surface contamination on the MgO protective layer. AC-PDP front panel samples were tested with Ne-Xe (4%) gas discharge after aging at elevated substrate temperatures. Real time analysis of the plasma composition near ...

Ferroelectric Bi4Ti3012 thin films have been grown on MgO ( 100) and MgO( 110) substrates by the pulsed laser deposition. X-ray diffraction studies show that the films on both substrates have preferential crystallographic orientation such that most of their c axes are close to the substrate normal direction. The film on MgO( 110) shows quadratic and hysteretic electro-optic characteristics with...

The kinetics of conversion of dihydroxyacetone (DHA) to methylglyoxal (MGO) were investigated in mānuka honeys and DHA-doped clover honeys stored between 4 and 37°C. Both the disappearance of DHA and appearance of MGO were confirmed as overall, first order reactions, albeit probably composites of multiple reactions. Increasing the storage temperature accelerated the rate of DHA loss and the ini...

We have studied the magnetic properties of Au (2 nm)/Co50Pt50 (3 nm)/Au (2 nm) multilayer films prepared on amorphous Al2O3/Si and (0 0 1) MgO substrates. The as-deposited films on both substrates are magnetically soft with an FCC structure and exhibit a perpendicular anisotropy. After annealing at 500 °C, the sample on the Al2O3/Si substrate has become magnetically isotropic but the sample on ...

This new method which is worked out in Isfahan University of Technology, makes it possible to analyze the phases quantitatively in minerals and powdered materials by X Ray Diffraction and without any reference material. To identify n unknown phases, n different combinations of phases, from fine and coarse fractions, or etc., must be obtained. Amorphous phases should not exist. Intensity ratios ...
