Ab initio MO calculations were carried out using the density functional method for the reaction intermediate of methanol synthesis by CO 2 hydrogenation. The energy change of the bridging-formate due to changing the Cu-Cu interatomic distance showed that the formate intermediate was formed at the ...

CO2hydrogenation to methanol is very promising [[2], [3], [4]]. It can be applied for the conversion of carbon dioxide in a large scale. The product, methanol, can be extensively used as chemical intermediate, solvent, fuel, and others. A ‘Methanol economy’ was even proposed by Prof...
In the case of PDMAEMA-PU, the coloured polymer was washed from acidified methanol and further passed through neutral aluminium oxide column after which pure white polymer was separated. Characterization of the synthesized polymers. The 1H-NMR spectra of the synthesized tri-block co-polymers ...
It was found that the rate constants for the reactions in weakly polar diethyl ether (ε = 4.34, ΕΤ(30) = 34.7) is equal to 0.7 × 10−2 L mol−1 s−1, whereas in the case of the same reaction in strongly polar methanol, the value is 9.34 × 10−2 L mol−1 s−...
Dynamic Modeling of a Reformed Methanol Fuel Cell System using Empirical Data and Adaptive Neuro-Fuzzy Inference System Models In this work, a dynamic MATLAB Simulink model of a H3-350 Reformed Methanol Fuel Cell (RMFC) standalone battery charger produced by Serenergy is developed... KK Justesen...
These values remained unchanged as the proportion of methanol increased. The saturated CD value was solvent dependent, which suggests that the a-helix conformation may be dependent on the solvent. The s0 values reported by Scholtz et al.12 are lower than those obtained in this study. ...
BH[sub 3]NH[sub 3] dimer and BH[sub 3]NH[sub 3] complexes of methane, hydrogen cyanide, ammonia, water, methanol, and hydrogen fluoride, are studied using the Møller–Plesset second-order perturbation theory and the 6-31++G** basis set to understand the features of dihydrogen bond. ...
