Computational Discovery of Fast Interstitial Oxygen Conductors [PDF]
arXiv, 2023 New highly oxygen-active materials may enhance many energy-related technologies by enabling efficient oxygen-ion transport at lower temperatures, e.g., below 400 Celsius. Interstitial oxygen conductors have the potential to realize such performance but have received far less attention than vacancy-mediated conductors.

Factors controlling oxygen migration barriers in perovskites [PDF]
Solid State Ionics 296 (2016) 71-77, 2016 Perovskites with fast oxygen ion conduction can enable technologies like solid oxide fuel cells. One component of fast oxygen ion conduction is low oxygen migration barrier. Here we apply ab initio methods on over 40 perovskites to produce a database of oxygen migration barriers ranging from 0.2 to 1.6 eV. Mining the database revealed that systems with

Oxygen depletion hypothesis remains controversial: a mathematical model of oxygen depletion during FLASH radiation [PDF]
Radiation Research . 2022. 197(2):175-183, 2020 Background: Experiments have reported low normal tissue toxicities during FLASH radiation, but the mechanism has not been elaborated. Several hypotheses have been proposed to explain the mechanism. The oxygen depletion hypothesis has been introduced and mostly studied qualitatively.

Accounts of Chemical Research, 2018 Work on the electronic structures of metal-oxo complexes began in Copenhagen over 50 years ago. This work led to the prediction that tetragonal multiply bonded transition metal-oxos would not be stable beyond the iron-ruthenium-osmium oxo wall in the periodic table and that triply bonded metal-oxos could not be protonated, even in the strongest ...

Improvement of a Mathematical Model to Predict CO2 Removal in Hollow Fiber Membrane Oxygenators
Bioengineering, 2022 The use of extracorporeal oxygenation and CO2 removal has gained clinical validity and popularity in recent years. These systems are composed of a pump to drive blood flow through the circuit and a hollow fiber membrane bundle through which gas exchange ...

Singlet Oxygen Generation as a Major Cause for Parasitic Reactions during Cycling of Aprotic Lithium-Oxygen Batteries [PDF]
Nature Energy 2, 17036 (2017), 2017 Non-aqueous metal-oxygen batteries depend critically on the reversible formation/decomposition of metal oxides on cycling. Irreversible parasitic reactions cause poor rechargeability, efficiency, and cycle life and have predominantly been ascribed to the reactivity of reduced oxygen species with cell components.

Effect of Oxygen Mole Fraction on Static Properties of Pressure-Sensitive Paint [PDF]
Sensors, Vol. 21, No. 4, 1062 (2021), 2020 The effects of oxygen mole fraction on the static properties of pressure-sensitive paint (PSP) were investigated. Sample coupon tests using a calibration chamber were conducted for polymer-based PSP (PHFIPM-PSP), polymer/ceramic PSP (PC-PSP), and anodized-aluminium PSP (AA-PSP).
