The Importance of Proper Oxygenation in 3D Culture
Frontiers in Bioengineering and Biotechnology, 2021 Cell culture typically employs inexpensive, disposable plasticware, and standard humidified CO2/room air incubators (5% CO2, ∼20% oxygen). These methods have historically proven adequate for the maintenance of viability, function, and proliferation of ...

The effects of incremental continuous positive airway pressure on arterial oxygenation and pulmonary shunt during one-lung ventilation [PDF]
Korean Journal of Anesthesiology, 2012 BackgroundAlthough one lung ventilation (OLV) is frequently used for facilitating thoracic surgical procedures, arterial hypoxemia can occur while using one lung anesthesia.

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.

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.

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.

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

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).
