Impact-induced vapor plumes produce a variety of chemical species, which may play an important role in the evolution of planetary surface environments. In most previous theoretical studies on chemical reactions within impact-induced vapor plumes, only volatile components are considered. Chemical reactions...
The REMs with different pore diameters serve as an ideal platform to investigate the spatial confinement effect of microchannels. In the voltammetry curve in Fig.1c, the REMs show a relatively high onset potential of 2.1 VRHEfor oxygen evolution, which provides an advantage for the generation of...
(1) H2SO4. As a strong oxidizing acid, changes in the dosage of H2SO4 affect the number of oxygen-containing functional groups of carbon materials, while also increasing the trace amount of impurities, such as sulfur [34]. (2) HNO3. HNO3 is the most commonly used liquid-phase oxidant,...
Sorbed Mn(II) is then oxidized to Mn(III/IV) either enzymatically (direct), using molecular oxygen and/or hydrogen peroxide (H2O2) as substrates, or indirect, as a response to metabolically produced reactive oxygen species (ROS) known to be produced in larger quantities during the exponential ...
Ozone itself is unstable and can quickly decompose into molecular oxygen leading to a low utilization rate [8]. Further, ozone alone does not cause complete oxidation of some refractory organic compounds, has a low reaction rate. The ozone is combined with H2O2, UV light, catalyst, ...
containsoxgenes, although their ability to oxidize thiosulfate has not been experimentally demonstrated. Moreover, as thiosulfate oxidation is affected by the availability of electron acceptors, it is possible that the oxygen gradient in biofilms may promote the development of novel thiosulfate-oxidizing ...
Oxidation studies were performed at 1100 °C in dry air and air containing fixed partial pressures of water vapor on a number of alloys and coatings that form α-Al2O3 scales under oxidizing conditions. The alloys investigated included RENÉ N5, PWA 1484, diffusion aluminide coatings (with an...
Plant genomes contain a large number of genes encoding for berberine bridge enzyme (BBE)-like enzymes. Despite the widespread occurrence and abundance of this protein family in the plant kingdom, the biochemical function remains largely unexplored. In this study, we have expressed two members of ...
Oceanic oxygen minimum zones (OMZs) are globally significant sites of biogeochemical cycling where microorganisms deplete dissolved oxygen (DO) to concentrations <20 µM. Amid intense competition for DO in these metabolically challenging environm
