By controlling the oxygen partial pressure ( p O2) and oxygen content in the copper simultaneously, contact angle can be varied between 125° and 22°. Evaluation of the Gibbs adsorption equation for the liquid/solid interface at 1300°C suggests that adsorption of a Cu‐O complex at that ...
According to the Arrhenius equation, the lifespan of an electronic device is cut in half when its temperature increases by 10 °C11,12. Therefore, it is necessary to develop heat sinks that can immediately release the heat generated by electronic devices. One of the properties required for ...
fabricated a new class of oxygen vacancy-enriched CeO2 catalyst with the stabilization of the crucial intermediate of *NO via inserting into vacant sites, which was conducive to the subsequent C–N coupling process rather than protonation [9]. Moreover, Zhang’s group reported a novel Mott–...
Bringing equations (3) and (5) into equation (2) and considering the Gibbs free energies of zeolite and bulk copper oxide are approximated as their respective DFT-computed electronic energies, we arrive at: where is the total electronic energy of a given Cu-containing MOR model,EMOR–4His ...
which provides ample edge/corner and step atoms as well as the electronic coupling between Cu and Pd leading to the lower of d-band center, the rough-surfaced CuPd alloy multicubes show much better electrocatalytic performance not only for formic acid oxidation but also for oxygen reduction ...
Joe et al. [82] discovered that the antimicrobial activity of ZnO NPs in dark conditions, which excluded the effect of reactive oxygen species (ROS), was primarily attributed to the disruption of the microbial cell wall by ZnO NPs and the elevation of Zn2 + ion concentration within the...
Analysis of the X-ray diffraction measurement of this sample at room temperature yields a grain size of approximately 6 nm applying the Scherrer equation with a shape factor K of 0.9 to the (200) Ti(C,N) diffraction peak, in good agreement with the results of HR-TEM. Patscheider et al...
(Fe/Fe) in slags fits the equation previously obtained in the plain FeO–FeO–CaO ternary system, and this ratio in the basic calcium ferrite slags is ten times as large as that in acidic iron silicate slags.(3) The iron contents in metallic copper are related to the oxygen potential, ...
Char yield can be applied to estimate limiting oxygen index (LOI), according to the Van Krevelen and Hoftyzer equation:[40] LOI ¼ 17:5 þ 0:4 CR where CR ¼ char yield According to this equation, the obtained values of LOI (37–41) for PAI and PAI/CuO-PVA NCs were higher ...
The CO2 binds to the interfacial Cu-Zr4+ sites that coordinate to the carbon and oxygen atoms, respectively allowing for partial electron transfer from the Cu into the CO2, which is stabilized by the coordination of the negatively charged oxygens and the Zr4+ cations. This is consistent with ...
