Reducing agents and bases were now oxygen poor species; oxidizing 还原剂和碱现在是贫氧物质;氧化性 figure 1 agents and acids wereoxygen-rich species. Oxidation-reduction was a complete transfer of oxygen from the oxygen-rich oxidizing agent to the oxygen-poor reducing agent; 剂和酸是富氧物质。氧...
While in the case of oxygen-rich, the positive formation energy of neutral oxygen vacancies is higher than the ones under oxygen-poor atmosphere. As a result, it is hard to generate a high concentration of oxygen vacancies under this atmosphere. These results indicate the oxygen vacancies are ...
However, the primary combustion by-product of carbon dioxide from the combustion of O2/RP-1 propellant has increased the average molecular mass of the exhaust gas (M) notably if compared to the by-products of mostly H2O, and unreacted H2 or O2 (depending on either fuel-rich or fuel-lean ...
Here, vanadium oxide nanobelts with sodium-poor and oxygen defect-rich were constructed by regulating the content of pre-embedded sodium ions to strike a balance between pre-embedded ions and structural stability. The introduction of trace sodium ions not only increases the spacing of vanadium oxide...
It must be avoided to bring too much Al in the steel as otherwise it leads to formation of Al2O3 rich nondeformable and hard inclusions. In Figure 1.7.3, the hypothetical aluminum activity, aAl, has been drawn higher in the slag than in the steel. It can be even opposite if Al2O3...
The nitrogen (N), phosphorus (P) and sulphur (S) ternary-doped metal-free porous carbon materials have been successfully synthesized using MOFs as templates (denoted as NPS-C-MOF-5) for oxygen reduction reaction (ORR) for the first time. The influences o
Rapid breathing (tachypnea):The body tries to compensate for low oxygen levels by increasing the rate of breathing, attempting to bring in more oxygen-rich air. Increased heart rate (tachycardia):Similar to rapid breathing, the heart rate increases to pump oxygen-deprived blood faster around the...
Note: Effluent recirculation (ER); hybrid constructed wetland (HCW); Wastewater type (WT); Piggery (P); Domestic (D); Oil-rich (O); Hydraulic loading rate (HLR); Organic loading rate (OLR); Recirculation flow ratio (RFR), recirculated volume to influent volume; Total suspended solids (TS...
Owing to the rich mesopores and the excellent performance of Pt itself, the catalyst had significant ORR electrocatalytic activity. The half-wave potential in 0.5 M H2SO4 solution was as high as 0.91 V, and the electrochemically active surface area was up to 95.3 m2 g−1....
of oxygen-containing intermediates in ORR and OER, which effectively boost the intrinsic activity of Co/CoFe@NC. The theoretical analysis also reveals the charge transfer from the metal layer to the NC layer, which can cause an electron-rich state on the latter and induce extra surface ...
