Biomass chemical looping gasification (CLG) is a novel technology for hydrogen production, where the oxygen carrier (OC) transfers lattice to catalytically oxidize fuel into syngas. However, OC gradually reduced, showing different reaction activities in CLG process. Fully understanding mechanism of molecules on perfect and reduced surfaces necessary, which ethanol using Fe2O3 as was introduced ...

The modeling and simulation of methane-oxygen combustion at high pressure requires a dedicated kinetic mechanism to obtain precise description the fuel decomposition. However, using detailed mechanisms literature in high-fidelity simulations, like direct numerical is not possible due cost. Accordingly, reduced chemical required, one proposed this study contains 17 species 44 reactions encompass...

in this paper, dynamical behavior of the delay mechanism of a special projectile controller is studied, using 3d finite element simulation. the controller considered here is among of high-acceleration mechanical controllers. due to high linear and angular accelerations of the projectile and also explosion risk, experimental investigation is very limited and almost impossible. so, numerical simu...

pioglitazone (pg) is one of thiazolidinediones used for the treatment of type ii diabetes mellitus. some reports of its hepatotoxicity exist, but the mechanism of its hepatotoxicity is not well known. in the present study, the protective effect of some atp suppliers are investigated against mitochondrial toxicity of pg in isolated rat mitochondria. mitochondrial viability was investigated by mt...
