The surface excess concentration of the surfactant (Γcmc) and the minimum surface area per surfactant molecule (Acmc) were calculated as follows (Tang et al., 2018):(3)Γcmc=−12.303nRT(∂γ∂logC)T(4)Amin=1NAΓcmcwhere the value of n stands for the number of species at the ...
摘要: In this chapter, we will explain why plasma is promising for CO2 conversion. First, we will give a brief introduction on plasma technology (Sect. 8.1), and highlight its unique feature for CO2...DOI: 10.1515/9783110665147-028 年份: 2019 ...

b stands for catalyst. Color codes: C, brown; N, silver; Ti, light blue; O, red; H, white. is more inclined to generate C1 species via the eight PCET steps, where the barriers of RDS are 1.51 eV for CO, 2.26 eV for HCHO, 1.59 eV for CH3OH and 0.70 eV for CH4, respectively...
Comparing these synthesis methods, CVD stands out as the most effective for synthesizing well-structured MWCNTs due to several advantages it offers. These advantages include better control over the geometry of nanotubes, lower process temperatures that minimize defects, precise control over growth paramete...
In Eq. (1) above, t, i and μ refer to the time period, cross-section unit (here, country) and the residual term respectively. The term ‘ln’ stands for natural logarithm. CO2refers to carbon dioxide (a greenhouse gas) emissions measured in metric tons per capita used as a proxy fo...
Environmental Chemistry Introduction Mineral waters are usually related to specific geological conditions, a rather limited rate of recharge, and often an increased gas flux. There are not many groundwaters in the world that are as highly enriched in magnesium and sulphate as the mineral waters discu...
Among absorbents stands lithium orthosilicate (Li4SiO4) for its high absorption capacity and thermal stability. Therefore, the present research aims to study and model the kinetics of CO2 absorption by Li4SiO4 in a temperature range of 550-650 degrees C. Results were consistent with a first ...
with V symbolizing the sandstone reservoir volume in m3 (under the flysch cap rock); ϕ denoting the effective porosity (%); ρ is the CO2 specific gravity property (in kg/m3); whereas ε stands for the sCO2 storage efficiency factor. In the context of the present study, the proposed...
The bonding electrons (EL): The number of electrons taking part in a bond. C=O bond is covalent, and Carbon and Oxygen share two electrons each. So, C and O have 4 bonding electrons. EN stands for electronegativity. Following the general formula [37,38] δ(a) = V(a) − [ENL...
