Abstract:
... The Bohart–Adams model has been one of the most widely used breakthrough models for the modeling of dynamic adsorption behaviors of water pollutants in a fixed-bed column. However, the fitting quality was often questioned by many researchers when the Bohart–Adams model was correlated with the experimental data. Recently, Chu (2020) discussed the two simplified forms of the Bohart–Adams model and t ...

Abstract:
... Perovskite materials have shown ultrasensitivity to atmospheres especially to O₂, which is due to the passivation effect of the surface defects. Identification of the chemical nature of the surface defects is thus of crucial importance for fundamental understanding of these materials, which is extremely difficult by experimental characterization. In this work, we systematically studied the adsorpt ...
