Numerical analysis of reaction-diffusion effects on species mixing rates in turbulent premixed methane-air combustion [PDF]

, 2009
The scalar mixing time scale, a key quantity in many turbulent combustion models, is investigated for reactive scalars in premixed combustion. Direct numerical simulations (DNS) of three-dimensional, turbulent Bunsen flames with reduced methane-air ...

Vacuum‐Induced Surface Reconstruction of Mn–Ce Oxides for Low‐Temperature Coupled Redox Catalysis

Angewandte Chemie, EarlyView.
Near‐surface reconstruction enhances low‐temperature redox catalysis in Mn–Ce mixed oxides. Sequential vacuum annealing and reduced‐pressure O2 treatment enrich Mn near the surface while preserving the CeO2 fluorite framework, promoting interfacial electron redistribution, oxygen activation, and redox cycling.
