In the present work we explore via first-principles simulations whether the ligand/cluster/support catalytic complex generated by CO oxidation over silver trimers deposited on the regular MgO(100) surface - i.e. a Ag3/carbonate or Ag3(CO3)/MgO(100) species - can be used as a catalyst in a different reaction: the selective oxidation of NO to NO2 (or NOox). The Ag3(CO3)/MgO(100) complex is first ...

Mechanically robust alginate-based nanofibrous scaffolds were successfully fabricated by electrospinning method to mimic the natural extracellular matrix structure which benefits development and regeneration of tissues. Alginate-based nanofibres were electrospun from an alginate/poly(vinyl alcohol) (PVA) polyelectrolyte complex. SEM images revealed the spinnability of the complex composite nano...

The lower crust of the Mesozoic Sierra Nevada batholith was made up of high MgO, garnet-poor and low MgO, garnet-rich pyroxenites. Both groups are genetically linked and are collectively complementary to the mafic to intermediate Sierran plutons. High MgO pyroxenites represent high pressure cumulates from a mantle-derived hydrous basalt or basaltic andesite, resulting in derivative magmas havin...

Objective(s): In recent years, nanotechnology has produced new forms of materials that are more effective than their predecessors. Magnesium is an essential element in the human body and certain studies have proved that its deficiency can induce anxiety in animals. In this study, the effect of magnesium oxide nanoparticles (MgO NPs) on anxiety, related behaviors, and interaction between their e...

introduction: some studies show magnesium has anticonvulsive effect in some animal models. despite of the availability of well-studied anticonvulsant drugs, this evaluation was not carried on new kind of magnesium supplement, magnesium oxide nanoparticles (nmgo). according to the interaction between magnesium and convulsion, this study was designed to evaluate the effect of nmgo on strychnine-i...

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 ...

We prepared highly aligned, biaxially textured BaxPb1−xTiO3 (PBT) on amorphous Si3N4 by using an ion-beam-assisted deposited MgO as a template layer. PBT was deposited on a biaxially textured MgO using sol-gel synthesis, metal-organic chemical-vapor deposition, and molecular beam epitaxy. The biaxial texture of the PBT was inherited from the MgO template. The reflection high-energy electron dif...

The structure of metal nanoparticles embedded inside dielectric nanowires/nanotubes, namely nanopeapods, has been of increasing interest due to their unusual photoresponse and optical adsorption properties. This paper presents a type of new inorganic nanopeapod: faceted Au nanoparticles inside MgO nanowires. The Au self-assembles into a nanoparticle chain during the vapor-liquid-solid growth of...

Adsorption of DzO on the MgO(100)/Mo(100) surface has been studied using temperature programmed desorption (TPD), reflection absorption infrared spectroscopy (RAIRS) and low energy electron diffraction (LEED). The epitaxially grown MgO(100) films show virtually identical water TPD spectra as the single crystal MgO(100) surface. The first, chemisorbed layer is adsorbed with the plane of the mole...
