Our density function theory calculations reveal that the catalytic activity of the main-group metals (Mg, Al and Ca) in oxygen reduction reaction is severely hampered by the tight-bonding of active centers with hydroxyl group intermediate, while the Mg atom coordinated to two nitrogen atoms has ...
Intracellular reactive oxygen species (ROS) detection Intracellular ROS were detected by DCFH-DA which could be oxidized by ROS to fluorescent 2,7-dichlorofluorescein. In detail, RAW264.7 cells were seeded in 24-well plates at a density of 2 × 104cells per well, followed by incubation for...
These RE elements typically react with oxygen to form a protective film on the alloy surface, preventing the formation of porous MgO films and thereby inhibiting further oxidation [18]. However, RE elements, particularly the heavy ones, are expensive, and automakers generally avoid using alloys ...
Magnesium and magnesium alloys are one of the lightest metallic materials. Their low density of 1.73 g/cm3and the resulting high specific strength make them a perfect alternative to slightly heavier aluminium alloys. The use of light alloys in aviation will result in reduced aircraft weight, which...
The effect of magnesium hydroxide on the flame retardant properties and mechanical properties of EVA/MH composites was studied through the limiting oxygen index (LOI), cone calorimeter test (CCT) and tensile test. The fire safety performance of the composites after MH introduction was systematically ...
As a result, understanding the interactions between MgONPs and plants is critical. The underlying mechanism of metal nanoparticles against bacterial infections appears to be the accumulation of reactive oxygen species (ROS) in cells, especially because the created ROS directly impair the cell’s ...
2.3.2. Scanning Electron Microscopy (SEM) To try to better characterize the two families of materials, with or without measurable SBET, highlighted by N2-physisorption, SEM has been performed in order to reveal the morphology and the texture of the samples. SEM images obtained for two samples ...
The analysis area of the rolled coarse grain sample was 1.46 mm × 1.1 mm and the analysis step was 5 μm. The analysis area of the extruded fine-grained sample was 0.146 mm × 0.110 mm, and the analysis step was 0.4 μm. Figure 2. Electron backscattered diffraction (EBSD) maps for ...
Magnesium has a strong affinity with oxygen and sulfur, which can effectively reduce the content of O and S in steel, and improve the quantity and morphology of inclusions in steel; moreover, it has an obvious modification effect on oxide inclusions and plays a role in purifying molten steel...
