In this work, magnetic graphene oxide (MGO) was prepared by in situ synthesis of magnetite nanoparticles in the presence of graphene oxide (GO). The prepared nanocomposite was characterized by applying scanning electron microscopy (SEM), X-ray diffraction (XRD, Fourier transform infrared spectroscopy (FTIR) and vibrating sample magnetometer (VSM). MGO was applied as an ...

Carbon-phenolic ablators are very efficient heat shields for atmospheric reentry vehicles: they able to protect a capsule from hyper thermal environments characterized by intense fluxes (>1 MW/m2) and high temperature (also exceeding 300°C). Ablative materials can be modified the addition of nano-fillers in order improve their performance: small amounts (in 2–5 wt%) enhance matrix material prop...

This study investigated the ultrathin Cu(002) capping nano-island effects on magnetic characterizations and microstructure of epitaxial FePt(001) films directly fabricated MgO(001) substrates at relatively low temperature 300 °C via electron-beam deposition. The enhancement coercivity is attributed to lowered exchange coupling FePt grains that begun from Cu atom behavior spreading in many direc...

A novel MgO-patched TiO2 microsphere photocatalyst demonstrated 10 times higher activity toward CO production from CO2 photoreduction with H2O vapor, when the reaction temperature increased from 50 to 150 °C. The catalytic performance of hybrid MgO-TiO2 was much more stable than TiO2, particularly at a higher temperature, likely due to easier desorption of reaction intermediates and the enhance...

In this study, Boron carbide was synthesized using Mesoporous Carbon CMK-1, Boron oxide, and magnesiothermic reduction process. The Effects of temperature and magnesium grain size on the formation of boron carbide were studied using nano composite precurser containg mesoporous carbon. Samples were leached in 2M Hydrochloric acid to separate Mg, MgO and magnesium-borat phases. SEM, XRD and Xray ...

The influence of several nootropic drugs (piracetam, pyritinol, meclofenoxat, methylglucamine orotate (MGO) and dihydroergotoxine (DHET) on both the ethanol preference and the enhanced seizure susceptibility after a single dose of ethanol was studied. Piracetam, MGO and DHET reduce the ethanol drinking in ethanol-preferring mice. The enhanced seizure susceptibility after a single dose of ethano...

backgrounds and aims: methylglyoxal (mgo) is an –α, β dicarbonyl aldehyde inevitably produced from triose-phosphate intermediates of glycolysis, and amino acid. increased mgo in blood leads to alterations in coagulation, clot permeability and thus, atherosclerosis in children with diabetes; however, the precise mechanism is not clear. the present study aimed to compare different concentrations ...

The geometric structure of MgO deposited on Fe(001) in ultrahigh vacuum by electron evaporation was determined in detail by using surface x-ray diffraction. In contrast to the common belief that MgO grows in direct contact on the Fe(001) substrate, we find an FeO interface layer between the substrate and the growing MgO structure which has not been considered thus far. This result opens new per...
