TL;DR: In this paper, the results showed that both the iron ore and the oxide scale worked well as an oxygen carrier and both oxygen carriers increased their reactivity with time, and the results were carried out in a laboratory fluidized-bed reactor that was operating cyclically with alternating oxidation and reduction phases.

TL;DR: The oxygen kinetics of purified beef heart cytochrome c oxidase were investigated and the effect of addition of various fixed concentrations of the inhibitors CO, HN3, HCOOH, HCN and H2S on the double reciprocal plot of respiration rate against oxygen concentration was studied.

TL;DR: Oxygen self-diffusion coefficients have been determined for MgO crystals over the temperature range 1300 −1750°C as mentioned in this paper. But diffusion is probably extrinsic in nature, and the diffusion coefficient for oxygen in this material is about two orders of magnitude less than that reported in the literature for magnesium.
Abstract: Oxygen self‐diffusion coefficients have been determined for MgO crystals over the temperature range 1300–1750°C. Results can be represented by the equation D=2.5×10—6 exp (—62 400/RT). By comparison with data for alkali halides and previous measurements for aluminum oxide, diffusion is probably extrinsic in nature. The diffusion coefficient for oxygen in this material is about two orders of magnitude less than that reported in the literature for magnesium.

TL;DR: In this paper, the kinetics of the carbon monoxide oxidation on a clean Pt (110) crystal were investigated in an ultra-high vacuum system by utilizing Auger electron spectroscopy, low-energy electron diffraction and residual gas analysis.
