Oxygen diffusion through perovskite membranes
... Perovskites (ABO3) are a prominent topic of research in materials science (high-Tcelectric conductor [1, 2], ferroelectric [3, 4] or high k dielectric [5], or magnetoresistance [6] material). Doping of these perovskites with multivalent cations on the A- and B- sites can lead to the simultaneous occ ...

... appropriate, because it is the give and take of electrons (+ seeks – and avoids +) that drives all of chemistry. As we will see, there is often a change in stereochemistry at the acceptor atom when the adduct forms. Recognition of Acids and Bases. Lewis Acids. Generally speaking, Lewis acids are not ...

Comparison of electronic structures of mass
... For Ag islands prepared by evaporating Ag atoms on the sputtered HOPG surface, it was previously shown that the Ag 3d binding energy is very sensitive to the particle size: with decreasing particle size, a positive core level shift can be found, resulting in a shift of 0.6 eV for about 1 nm-sized pa ...
