Importance of Methane Chemical Potential for Its Conversion to Methanol on Cu-Exchanged Mordenite

Copper-oxo clusters exchanged in zeolite mordenite are active in the stoichiometric conversion of methane to methanol at low temperatures. Here, we show an unprecedented methanol yield per Cu of 0.6, with a 90–95 % selectivity, on a MOR solely containing [Cu₃(μ-O)₃]²⁺ active sites. DFT calculations,...

Numerical analysis of heating rate effect on spalling of high-performance concrete under high temperature conditions

High-performance concrete (HPC) is vulnerable to spalling under high temperature conditions and it has been found that the heating rate can exert a tremendous effect on spalling of HPC. To prevent HPC from spalling, the heating rate effect should be understood. However, quantitative analyses are still lacking and the heating rate effect has...
