Increasing the number of single vacancies in quantum antidots strengthens the cumulative repulsive potential and consequently enhances the collective interference of multiple-pocket scattered quasiparticles inside quantum antidots, creating multilevel quantum hole states with a tunable gap from the telecom to...
vacancy lattices, spaced by a single Te atom, reaching the ultimate downscaling limit of antidot lattices. Increasing the number of single vacancies in quantum antidots strengthens the cumulative repulsive potential and consequently enhances the collective interference of multiple-pocket scattered quasipartic...
Moreover, oxygen vacancies can be generated in the reduced spinel structure, which promotes the adsorption and activation of CO2 molecules to produce O· radicals to gasify the carbon deposits [17] (Table 1). Despite the strong MSI and high surface area, the intrinsic acidity of Al2O3 ...
When Ce4+ was reduced to Ce3+, lattice oxygen was released and oxygen vacancies were formed, which improved the adsorption of oxygen species like O2 or CO2 to generate oxygen radicals, thus reducing the carbon deposition on the surface. However, an excessive amount of CeO2 may cover the Ni...
