In oxygenated solutions, minerals with wide working ranges give, at low rotation speeds, voltammograms that show limiting currents corresponding to the diffusion currents calculated from the Levich equation for a 4-electron reduction of oxygen to water. Departure from Levich conditions is observed at ...
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 ...
The cluster is stabilized by two anionic centres due to AlISP lattice sites at the entrance of the MOR side pocket (b) so that the extra-framework oxygens responsible for the initial C–H activation are pointing towards the main channel of MOR (a). The charge due to the remaining AlI...
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 ...
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–...
Quercetin 2,3-dioxygenase is a copper-containing dioxygenase 2–6 with copper(II) in the active site, which catalyzes the oxygenolysis of 3-hydroxyflavones ( 1,2 ) to the corresponding depsides ( 3,4 ) as a result of the oxidative cleavage of the heterocyclic ring (equation 1). ...
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...

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 ...
