Sentence examples for fast oxygen from inspiring English sources
Fast relaxations proceed by fast oxygen movement around cations, while slow relaxations require slow cation diffusion.
Previous DRIFTS and TPR/TPO studies had shown that the monomeric vanadyl species are able to adsorb toluene dissociatively, and that in the absence of gas-phase oxygen the desorption of oxygenated products from these species cannot occur, since the capability of fast oxygen insertion into toluene and desorption of oxygenates is associated with polymeric and crystalline vanadia species.
As it was shown, detectable weight loss due to the fast oxygen desorption begins in these ferrites above 573 K.
Oxygen isotope heteroexchange and conductivity/weight relaxation studies demonstrated that these interfaces provide a path for fast oxygen diffusion.
But in our case, the fast oxygen diffusion is provided by the loading-dependent reduction of the activation energy inherent for single-file diffusion [23].
Here we report our results on a computational study to achieve rational design of SOFC cathodes with fast oxygen reduction kinetics and rapid ionic transport.
Considering the response time of the other oxygen probes, it seems that the reported molecular probe can be implemented in design of faster oxygen sensors.
The MnOx has higher oxygen storage capacity, and faster oxygen absorption and oxide reduction rates than the present commercial ceria-stabilized alumina support materials.
Many studies concentrate on improving the cathode part for better oxygen dissociation and reducing the electrolyte thickness for faster oxygen transfer.
I U polarization and impedance analysis indicated that the faster oxygen reduction reaction at the open cathode is responsible for the power density improvement.
As cofactor supply is critical for the cascade reaction, various set-ups were tested: increasing concentrations of the recycling enzyme, different initial NAD+ concentrations, as well as the use of a bubble reactor for faster oxygen diffusion.
