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).

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 ...

Reactive Oxygen and Sulfur Species: Partners in Crime
Oxygen, 2022 The emergence of complexity requires cooperation, yet selection typically favors defectors that do not cooperate. Such evolutionary conflict can be alleviated by a variety of mechanisms, allowing complexity to emerge.

Oxygen, 2022 Cisplatin-induced acute kidney injury (AKI) is the main factor restraining the clinical application of cisplatin. The AKI is associated with high mortality and morbidity, but no effective pharmacological treatment is available at present.

Reactive Oxygen Species Signaling Pathways: Arbiters of Evolutionary Conflict?
Oxygen, 2022 In the history of life, cooperation between biological units has led to increased complexity, e.g., eukaryotic cells and multicellular organisms. Cooperation requires limiting the gains of “defectors” in favor of the cooperative higher-level unit.

Oxygen and Cation Ordered Perovskite, Ba2Y2Mn4O11 [PDF]
, 2004 A three-step route has been developed for the synthesis of a new oxygen-ordered double perovskite, BaYMn2O5.5 or Ba2Y2Mn4O11. (i) The A-site cation ordered perovskite, BaYMn2O5+d, is first synthesized at d ~ 0 by an oxygen-getter-controlled low-O2-pressure encapsulation technique utilizing FeO as the getter for excess oxygen.

Deciphering mechanisms of enhanced-retarded oxygen diffusion in doped Si [PDF]
Appl. Phys. Lett. 103, 251909 (2013), 2013 In this letter, we study enhanced-retarded diffusion of oxygen in doped silicon by means of first principle calculations. We found that the migration of oxygen dimers can not be significantly affected by strain, doping type or rate. We attribute the enhanced oxygen diffusion in p-doped silicon to reduced monomer migration energy, and the retarded ...

Oxygen and nitrogen abundances in nearby galaxies. Correlations between oxygen abundance and macroscopic properties [PDF]
Astron.Astrophys. 425 (2004) 849-869, 2004 We performed a compilation of more than 1000 published spectra of HII regions in spiral galaxies. The oxygen and nitrogen abundances in each HII region were recomputed in a homogeneous way, using the P-method. The radial distributions of oxygen and nitrogen abundances were derived.
