There was no bulk oxidation of the silver. 银不会发生体相氧化. 辞典例句 Aryl disulfides, for example, inhibit polyolefin oxidation. 例如芳基二硫化物可抑制聚烯烃的氧化. 辞典例句 展开全部 英英释义 Noun 1. the process of oxidizing; the addition of oxygen to a compound with a loss of electrons...
terminal electron acceptors such as oxygen, nitrate, or oxidized metals. Sulfide is a known phytotoxin, and its belowground oxidation is considered a detoxifying reaction for plants inhabiting coastal marine ecosystems19. Based only on amplicon sequencing of the 16S rRNA gene, sulfur oxidation coupled...
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, ...
Single-atom catalysts (SACs) have received growing interests in various catalytic fields due to the utmost utilization efficiency of metal atoms1,2,3,4,5,6,7,8,9,10,11. In addition, distinct local structure of SACs also provides an in-depth comprehension to the intrinsic structure-performance...

In addition, the oxidations of ethene and ethane by vanadyl cation VO 2 + are studied by ab initio theory. The oxidation of ethene by VO 2 + is suggested to proceed via a conceptually new mechanism which involves a direct oxygen transfer from the metal to the olefin to afford acetaldehyde...
In addition, when the engine is generating the exhaust temperatures of about 500 °C, and the engine-out NOx level is very high, even a 20% conversion of NO into NO2 will provide a high absolute level of NO2 to DPF. Therefore, in practice, the DPF system can provide effective PM ...
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...
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
This change of iron bioavailability likely put selective pressure on the evolution of life. This element is essential to most extant life forms and is an important cofactor in many redox-active proteins involved in a number of vital pathways. In addition, iron plays a central role in many ...
