Electrons in conventional metals become less mobile under the influence of electron correlation. Contrary to this empirical knowledge, we report here that electrons with the highest mobility ever found in known bulk oxide semiconductors emerge in the str
The involved electrons and phonons must obey the rules of momentum conservation and the compatibility relation between little groups, since they possibly locate at different points in the Brillouin Zone. non null/null means the allowed/forbidden transition channels. Due to the lack of in-plane ...
Molecular compounds are chemical substances formed from the sharing of electrons between atoms or by covalent bonding. On the other hand, ionic compounds are formed when instead of sharing, the electrons are transferred between cations and anions occurring due to ionic bonding. Generally, molecular co...
absorption spectroscopy was also measured to elucidate the local chemical environment of Ru within both samples (Fig.2c). The absorption edge energies of Ru1/MAFO-900 and Ru/MAFO-500 were identical and matched that for RuO2, consistent with the presence of Ru4+species observed by XPS; howe...
(C2H5OH), have garnered significant attention due to their potential to tap into existing large markets4,5,6,7. Currently, most research efforts are focused on the design of novel copper-based catalysts to enhance the production activity of C2+products in alkaline or neutral electrolyte systems...
However, due to the mutual coupling of S and σ, it is difficult to improve the zT value by tuning a single parameter. To address this problem, common strategies are to suppress the κL of existing TE materials through introducing defects14,15, alloying16,17, nanostructures18, and ...
to penetrate between the lobes. This double-cavity-type structure occurs because thepstate has a node in the middle, and in the absence of electron density at the node, there is no Pauli repulsion that pushes electrons of water molecules away from this region. The pseudopotential approach ...
X-ray photoelectron spectroscopy (XPS) of Pt4fspectra further confirmed the chemical state change of Pt single atoms on Pt1/CF where Pt mainly existed as Pt4+(~76%) with a small quantity of Pt2+(24%) due to the strong interaction with CoFe2O4support31. After water treatment, an increa...
while the formation time for H3+from 2-propanol only increased by a factor of 1.9. Our previous study14found that the roaming H2molecule abstracts the third proton from the same atom (carbon) faster (~100 fs) than from the adjacent atom (oxygen), due to the longer roaming time (and ...
(Fig.2a). Although plasmonic nanostructures have been reported to be catalytically active in electrocatalytic HER reactions40, few photocatalytic HER reactions have been demonstrated on AuNPs, possibly due to the difficulty in extracting plasmon-generated hot electrons. With CoTPyP molecules only, the...
