As the pressure in air is higher than in water, the water will accumulate oxygen from the atmosphere. This process eliminates when the pressure in both mediums is equal when the water is saturated with DO. Accordingly, this physical process strongly depends on the exchange between the water ...
In addition, anoxia may affect the plasticity of cold tolerance in various Diptera species. Rapid cold hardening (RCH) is a form of phenotypic plasticity whereby a non-lethal cold "shock" increases the insects' chill tolerance21. While anoxia was able to elicit RCH in the house fly Musca ...
The static real dielectric constants of the defective structures are increased compared with the intrinsic one, which is attributed to the level caused by the Ga-4s states in the bandgap. Extra peaks are introduced in the absorption spectra, which are related to Ga-4s and O-2p states. ...
durable completely noble metal-free electro-catalyst for oxygen reduction reaction (ORR) in proton exchange membrane (PEM) fuel cells, oxygen evolution reaction (OER) in PEM based water electrolysis and metal air batteries remains one of the major unfulfilled scientific and technological challenges of...
27 August 2015 activation on LaMnO3 supports in alkaline media Shin-Ae Park, Eun-Kyung Lee, Hannah Song & Yong-Tae Kim Ag is considered to be one of the best candidates for oxygen reduction reaction electrocatalysts in alkaline media for application in various electrochemical energy devi...
1. Introduction About 1% of the world human population live permanently at >2500 m altitudes, mainly in non-Western countries [1]. The major health problem these people constantly face stem from breathing an atmosphere impoverished in oxygen (O2). On average, up to 10% of the population ...
a new activity of the oxygen sensor, the soluble Ru(II) complex BsOx, was demonstrated, which is a mixture with amphotericin B that caused a significant increase in its antifungal activity. Thus, it is also possible to demonstrate the synergistic effect of compounds active against the microorgan...
In this work, the quaternary Cr–Si–O–N coatings with different oxygen contents were deposited by a multi-arc ion plating process in a N2 + O2 atmosphere. The microstructure, mechanical, high-temperature oxidation and electrochemical corrosion resistance properties of the Cr–Si–O–N coatings,...
precious metal electrocatalyst for oxygen reduction reaction (ORR), a novel FexNy/NC nanocomposite—that is composed of highly dispersed iron nitride nanoparticles supported on nitrogen-doped carbon (NC)—was prepared by pyrolyzing carbon black with an iron-containing precursor in an NH3 atmosphere. ...
found that the oxygen vacancy content of the OVH-TiO2 obtained by reducing TiO2 aggregates in a hydrogen atmosphere was much higher than that of the original TiO2 samples [27]. As another method, ion doping is also an effective way to adjust the oxygen vacancy content. Moreover, a ...
