Hydrated lime (Ca(OH)2)- and reactive magnesia (MgO)-activated ground granulated blast-furnace slag (GGBS) have shown advantages in geotechnical applications compared with Portland cement (PC). To apply these two novel binders slurry form to field applications, the properties of their grouts need be investigated, which is objective this study. The heat hydration, bleeding, viscosity, setting be...

Using a novel experimental procedure in the field of ceramics/materials science that is based on the precise microanalysis (scanning electron microscopy, coupled with wavelength-dispersive spectroscopy) of the phases that are present in equilibrated specimens, the solid-state compatibility relations in the subsystem MgAl2O4–CaAl4O7–CaO– MgO and the melting relationships in the subsystems MgAl2O...

Bioactive glass with composition SiO2, Na2O, CaO, P2O5 with MgO additive were synthesized through a quick alkali mediated sol–gel method. MgO was substituted for SiO2 in glass formula up to 5 wt% and in-vitro bioactivity of the samples (precipitation behavior of carbonated apatite likely bone layer) was evaluated by soaking them in simulated body fluid (SBF). The characterizations were carried ...

Biologically derived hydroxyapatite from calcinated (at 850 degrees C) bovine bones (BHA) was doped with 5 wt% and 10 wt% of SiO(2), MgO, Al(2)O(3) and ZrO(2) (stabilized with 8% Y(2)O(3)). The aim was to improve the sintering ability and the mechanical properties (compression strength and hardness) of the resultant BHA-composites. Cylindrical samples were sintered at several temperatures betwe...

B1–NaCl-structure CrN~001! layers were grown on MgO~001! at 600 °C by ultrahigh vacuum reactive magnetron sputter deposition in pure N2 discharges. X-ray diffraction analyses establish the epitaxial relationship as cube-on-cube, (001)CrNi(001)MgO with @100#CrNi@100#MgO , while temperature-dependent measurements show that the previously reported phase transition to the orthorhombic Pnma structur...

A kinetic model for the conversion of dihydroxyacetone (DHA) to methylglyoxal (MGO) in honey is proposed; a building block approach was used to create the model. Artificial honeys doped with DHA and individual perturbants were fitted first, then multiple perturbants (alanine, proline and iron, and combinations of these) were fitted before comparing the simulation to real honey samples (doped cl...

− Plasma display panel(PDP) uses the mixture of inert gases to generate a discharge inside display pixels. Inside of PDP, there exists highly reactive conditions in the gap between two glass panels. Chemical properties of MgO layer and phosphor have been investigated as a function of discharge and thermal process. Impurities such as CO, CO2, OH and H2O in discharge region may deteriorate the ch...

Diabetes is associated with elevated plasma glucose, increased reactive aldehyde formation, oxidative damage, and glycation/glycoxidation of biomolecules. Cellular detoxification of, or protection against, such modifications commonly requires NADPH-dependent reducing equivalents (e.g. GSH). We hypothesised that reactive aldehydes may modulate cellular redox status via the inhibition of NADPH-ge...

A 2.5 monolayer (ML) thick graphene film grown by chemical vapor deposition of thermally dissociated C(2)H(4) on MgO(111), displays a significant band gap. The apparent six-fold low energy electron diffraction (LEED) pattern actually consists of two three-fold patterns with different 'A' and 'B' site diffraction intensities. Similar effects are observed for the LEED patterns of a 1 ML carbon fi...

OBJECTIVES/HYPOTHESIS Low pH, hydrogen peroxide generation, and the hyperosmolarity mechanisms of antimicrobial action are ubiquitous for all honeys. In addition, manuka honey has been shown to contain high concentrations of methylglyoxal (MGO), contributing the relatively superior antimicrobial activity of manuka honey compared to non-MGO honeys. In high concentrations, manuka honey is effecti...
