TL;DR: In this article, a biofilm reactor, the moving bed reactor, was studied for nitrification purposes and the experimental results showed that when alkalinity was in excess and there was no organic load, either the ammonium or the oxygen concentration would be limiting for the nitrification rate.

TL;DR: In this article, the authors present an overview of progress made in preparing oxygen defective metal oxide nanostructures and probing the role of oxygen vacancies on the performance of metal oxides.

TL;DR: In this article, the authors examined the relationship between the two parameters measured by the 18O/16O Isotope Exchange Depth Profile (IEDP) method, the oxygen surface exchange coefficient, k*, and the oxygen tracer diffusion coefficient, D*, and interpreted the strong correlation observed between k* and D* in terms of oxygen vacancies playing a major role in the surface exchange process for these materials.

TL;DR: In this paper, a CeO 2 thin film has been subjected to Ar + bombardment at 298 K to induce the reduction of its outmost layers by preferential removal of oxygen, and an XPS study of the altered layer at normal and grazing angle has been carried out.

TL;DR: A mixed-conducting perovskite-type Ba0:5Sr 0:5Co0:8Fe0:2O3 (BSCFO) membrane reactor with high oxygen permeability was applied for the activation of methane as mentioned in this paper.
