18.94 ± 9.22% of electron in CH4was used to iron reduction, 28.81 ± 8.52% of electron in CO2was used to iron oxidation, and the remains were to produce biomass and other metabolites. Microbial aggregates were
The morphology and thickness of the membranes were investigated using a scanning electron microscope (SEM, FEI Magellan 400 field emission XHR-SEM) operated at an accelerating voltage of 3 kV and a probe current of 6.3 pA. No conductive coating was applied to the samples. The membranes were mo...
polymers of intrinsic microporosity (PIM), thermally rearranged (TR)) [11] (as shown in Fig. 1) materials have been constructed into high-quality membranes with the excellent gas separation performance. There is a growing interest on the number of studies investigating hydrogen separation potentials...
most of the reported single-atom catalysts tend to form two-electron-product CO rather than hydrocarbons due to the favorable energy barrier of CO production as well as the highly dispersed and low loaded catalytic sites25. In addition, most of the reported single-atom sites are nitrogen-coordin...
How many VSEPR electron groups are on the central atom in the Lewis structure for CH2O? In covalent bonds, how many pairs of electrons are shared in a single bond? What is the total number of lone pairs on the central atom in the 'correct' or 'best' Lewis structure of the following...
bElectron selectivity (Selelectron) of CH4: Selelectron(%) = (8 v(CH4))/(8 v(CH4) + 2 v(CO) + 2 v(H2) + 2 v(HCOOH)) × 100%; cProduct selectivity (Selproduct) of CH4: Selproduct(%) = (v(CH4))/(v(CH4) + v(CO) + v...
CH4and N2O emissions flux and cumulative were investigated according to the method described by Zhang et al. (2013) [10]. Briefly, N2O and CH4emissions flux of gas samples were investigated with a gas chromatograph equipped with an electron capture detector (ECD) and flame ionization detector (...
The cell morphology of the PLC films and control surfaces after 72 h was observed using a field emission scanning electron microscope (SEM; Regulus 8100, HITACHI Ltd., Kyoto, Japan). Regarding the SEM observation, freeze-drying was used to fix the cells on each sample surface, and cell morp...
