TL;DR: Oxygen transport and surface reaction measurements have been obtained for La0.6Sr0.4Co0.2Fe0.8O3−δ using the conductivity relaxation technique as discussed by the authors.

TL;DR: In this paper, the authors examined the catalytic combustion of methane by supported palladium oxide catalysts (2 wt.-% Pd/La2O3·11A12O3) for several oxygen partial pressure levels over the temperature range from 40-900°C using temperature-programmed reaction and slow ramp and hold temperature-time transient techniques.

TL;DR: The electrical properties and defect structure of selected compositions in the SrTi1−xFexO3−y system (x = 0-0.8) have been studied using van der Pauw 4-point conductivity measurements and electron energy loss spectroscopy (EELS) as mentioned in this paper.

TL;DR: In this paper, a detailed study of the potential physical mechanisms of microbial inactivation by cold atmospheric plasmas is presented, with the Bacillus subtilis spores as a model microorganism and an atmospheric-plasma plume in helium flow, optical emission spectroscopy and inactivation kinetics are used to demonstrate the dominating role played by reactive oxygen species (e.g., atomic oxygen and OH) as well as the minor contributions of the UV photons, heat, charged particles, and electric fields.
Abstract: This paper presents a detailed study of the potential physical mechanisms of the microbial inactivation by cold atmospheric plasmas. With the Bacillus subtilis spores as a model microorganism and an atmospheric-plasma plume in helium flow, optical emission spectroscopy and inactivation kinetics are used to demonstrate the dominating role played by the reactive oxygen species (e.g., atomic oxygen and OH) as well as the minor contributions of the UV photons, heat, charged particles, and electric fields. To differentiate the concentrations of the reactive oxygen species, an atmospheric helium-oxygen plasma is also used for the spore inactivation. Results with the helium and the helium-oxygen plasmas are contrasted to highlight how the production of the spore-killing oxygen species may be enhanced

TL;DR: A comparison of oxygen isotope analyses of natural and synthetic phosphates using three methods in current use and Ag3PO4 as the analyte was made by as discussed by the authors, who concluded that conventional fluorination using BrF5 provides the most precise and accurate measurements.
