TL;DR: In this paper, an oxygen carrier consisting of 60% NiO and 40% NiAl2O4 was used in a 10 kW CLC reactor system for 160 h of operation with natural gas.

TL;DR: Calculations were made which show that the inner and outer shell membranes, if dry, are a negligible barrier to gas diffusion compared to the shell, which means that the egg shell is of prime importance in determining oxygen uptake and carbon dioxide and water vapor loss by the developing embryo.

TL;DR: In this paper, a fluorinated polyimide precursor for carbon molecular sieve (CMS) membranes was explored, and a strong correlation was found between the amount of oxygen available during pyrolysis and separation performances, thereby supporting the above hypothesis.

TL;DR: In this article, a solution process utilizing iron metal and fluorosilicic acid solutions as precursors was used to synthesize nanostructure iron oxyfluoride compounds of tunable oxygen content.
Abstract: Nanostructure iron oxyfluoride compounds of tunable oxygen content were fabricated by a solution process utilizing iron metal and fluorosilicic acid solutions as precursors. Simple adjustment of the synthesis atmosphere, temperature, and time enabled the fabrication of iron oxyfluoride materials with compositions spanning over the entire range from pure FeF 2 to FeOF. Nanocomposites were fabricated from iron oxyfluorides of various oxygen content and activated carbon in order, for the first time, to evaluate the impact of oxygen on the iron fluoride electrochemical performance. The introduction of oxygen proved beneficial to cycling stability but at the expense of reversible capacity. A combination of electrochemical and structural characterization analyses was performed to identify the iron oxyfluoride reaction mechanism.
