as the cathodically electrolytic hydrogen is proposed as an ideal energy carrier for the storage of sustainable but intermittent energy, such as wind and solar energy1,2,3. Current bottleneck mainly originates from four-electron process in anodic oxygen evolution reaction (OER), which requires larg...
First, the thermodynamic formation energies showed that the oxygen instability induced by Li+-extraction is much larger for Li2TiO3 than that for Li2MnO3. Second, the [[EQUATION]]-type Mn(t2g3)O hybridized band in the low energy state for the Mn oxide broadened the O 2p-bandwidth, ...
fitting to the Arrhenius equation, the activation energy (Ea) was found to be 0.3 eV51,52. The higher value ofEaalso suggests a lower conductivity. As shown in Supplementary Fig.15b, another different conduction mechanism dominates at the lower temperature region from 355 to 365 K, which...
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–...
(CPET) steps are readily triggered by attacking the oxygen atoms and forming H2O, after dehydration, *CO intermediate can be easily desorbed as gaseous CO molecules when the binding energy between the catalyst and the intermediate is relatively low. In contrast, if the binding energy is strong,...
Such metallized films often are used because they provide both good water and oxygen resistance. A picture of a direct metallizing process is shown on the Vaccuplast website.15 Vacuum metallizing is a batch process in which the film to be metallized is loaded onto the unwind zone of the ...

Aluminium frame keeps the structure light and easily adjustable by its occupants. Windows sections within the structure provide a full control of sunlight during the all seasons. What is more, the facade works along the underground heating, cooling systems, rainwater filtration and solar energy system...

tailoring the number of metal-oxygen bonds can be achieved by H2-reduction treatments or other strategy on reducible oxides23,24, whereas often at the cost of destabilizing the catalyst, arousing aggregation of single atoms. Therefore, strategies to regulate the MSI as well as the catalytic perfo...
