In the present study, fine dispersed I-phase particles and deformation grains in the bimodal microstructure with strong texture can strengthen the alloy, while fine and complete dynamic recrystallization grains with weak texture can enhance ductility [60]. In conclusion, nanoscale I-phase particles' ...
This manifests the late origin of serpentine as a consequence of forsterite replacement according to: 4Mg2(SiO4) + 6H2O = Mg6(Si4O10)(OH)8 + 2Mg(OH)2 (9) The acid stage is poorly represented due to the almost complete lack of sulfides. Some schoenfliesite grains have been locally ...
The main reason for the poor corrosion resistance of magnesium alloys is that Mg(OH)2, the main component of the surface film, is not stable in acidic, neutral, and weak alkaline solutions [17,22]. In particular, when the solution contains highly corrosive ions, such as Cl− which can...
STRONG ACID–WEAK BASE TITRATION(强酸弱碱):Only the pH range of methyl orange falls within the steep section of the curve.——只有甲基橙的pH范围落在曲线的陡峭部分内。 WEAK ACID–WEAK BASE TITRATION(弱酸弱碱):no prominent steep ...
Still, these skyships are effective in dropping solid missiles (or such things as acid or flaming oil) upon hostile forces. The buoyancy of such a vessel is greatest close to the ground, where the air is thickest. The maximum height at which a skyship may be con- trolled is 3600, ...
More importantly, in Mg-ZnO QDs the weak 439 cm–1 peak is involved in a broad band, reflecting the diminution of crystallinity induced by Mg incorporation. The presence of oleic acid (OA) attached on the surface of QDs is unambiguously evidenced by the intense and well resolved peaks at ...
to form carbonic acid:(10)[Math Processing Error]CO2(aq)+H2O→H2CO3(aq) This is a relatively slow, activated process that becomes faster at high temperature, promoting carbonatization. The absence of a clear temperature dependence of the corrosion of Mg and the strong positive temperature effe...
As used herein, “pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic gr...
