oxygen/ equations of statehigh temperatureshigh pressuresEquations of state are constructed for He, Ar, H 2 , D 2 , N 2 ,O 2 , CO, CO 2 , and CH 4 in the temperature range of (1–20) × 10 3 K and at pressures up to 40 GPa on the basis of the model of canonical equation...
Oxygen-containing carbons are promising supports and metal-free catalysts for many reactions. However, distinguishing the role of various oxygen functional groups and quantifying and tuning each functionality is still difficult. Here we investigate the r
Activation Energy for Oxygen Chemisorption on Carbon at Low Temperatures The kinetics of oxygen chemisorption on resin chars were investigated in this study. The Elovich equation was employed to facilitate the interpretation of ... H Teng,CT Hsieh - 《Industrial & Engineering Chemistry Research》 被...
Mathematically, this is equivalent to evaluating Equation (3), which is used to compute the offline emergent dynamics (see Section “Model output and offline diagnostics”), except here, a standardized prey field is used instead of the emergent monthly mean biomass fields. By using a standardized...
• The synthesised CNFs possess excellent magnetic response and presence of oxygen containing functional group on the surface makes it a good colloidal solution. Wang et al. (2015) • The maximum adsorption of DOX at solution pH in 9.0. ...
(Fig.3band Supplementary Fig.25), suggesting the water molecules adsorption and the generation of phenolic -OH over PyC700. The synchronous peak intensity changes of phenolic -OH and H2Oadthroughout the gold recovery process implied that the H2Oadmolecules significantly contributed as oxygen sources...
Assuming that the overall process of oxidation is in the pseudo-steady state normally adopted for solid gas reactions, the kinetic equation can be derived as follows: The diffusion rate of oxygen in the decarbonized layer: (7-9)R1=−Deff×dC(x)dx(Fick's First Law) The reaction ...

dissolved oxygen concentrations obtained with the Winkler method (O2range = 230–330 µmol kg−1, slope = 0.94 ± 0.01,R2 = 0.98,P < 0.001). The total amount of dissolved oxygen consumed during incubation (ΔO2, mmolO2) was obtained by using the equation:...
Cao et al. (2011) established a regression equation based on limestone dissolution rate, precipitation, soil respiration rate and net primary productivity, and estimated that the karst carbon sink in the Pearl River Basin is 1.85 Tg C/a, considering the distribution of carbonate rock types as ...
