would cause the S:C ratios for rapid sulfurization to be underestimates of the effective carbon preservation per sulfur atom. Using observed sulfur and carbon fluxes from Cariaco Basin and randomly picked values within our assigned ranges of sinking/burial times within each box and S:C ratios (...
2e), which suggests the oxidation valence of Zn atom as +2 in PcCu-O8-Zn42. Figure 2f displays the radial structure functions of PcCu-O8-Zn and clearly demonstrates the characteristic Zn-O coordination in PcCu-O8-Zn with intensive peak at around 1.55 Å. The absence of obvious ...
Carbon dioxide is a chemical compound made up of a carbon atom and two oxygen atoms. Each of the oxygen atoms is attached to the central carbon atom by a double covalent bond. The C-O bond has a length of 116.3 pm. The configuration of the compound is linear and centrosymmetric. Its ...

[146] used a custom-built large-area [Cs0.05(FA0.85MA0.15)0.95]Pb0.9(I0.85Br0.15)3 (CsFAMA)-based perovskite solar cell (Vop = 4.6 V, Isc = 4.3 mA), single-atom Co anchored on Zr6-cluster-porphyrin framework hollow nanocapsules (Co-SAs/Zr-CPF) as low-cost catalyst for CO2RR, an...
mass%, a carbonaceous material of 1 to 10 mass%, Al or an Al-containing alloy of 0.5 to 12 mass%, nitride having standard generated Gibbs energy per 1 molar of a nitrogen atom in nitride at a maximum temperature during a heat treatment which is larger than standard generated Gibbs energy...
preferably C1-C3-alkyl group or a C6-C10-, preferably C6-C8-aryl group or in the case of Si- or P-containing radicals can also be a halogen atom, preferably a chlorine atom, or two adjacent radicals R5, R6, R7, R8, R9 or R10 together with the carbon atoms connecting them form a...
Preferably, alkyl groups have from one to eight carbon atoms, alternatively from one to four carbon atoms, alternatively one or two carbon atoms, alternatively one carbon atom. The alcohol used in the ethylene carbonylation reaction corresponds to an alkyl group, as defined above, substituted with...
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
