Anelastic Relaxation of Protonic Defects in M3+-Doped BaCeO3

When perovskite-structured BaCe03 is doped with M ~ + ions (e.g., ~ d ~ + , Gd3+,yb33 that substitute on ce4+ sites, oxygen-ion vacancies are created for charge compensation. However, when treated in water vapor, the vacancies are replaced by protons, which take the form of OH' ions. This treatment makes the materials a good protonic conductor. Questions about the defect structure of the proton...

Geometrical aspects of protein folding

These lectures will address two questions. Is there a simple variational principle underlying the existence of secondary motifs in the native state of proteins? Is there a general approach which can qualitatively capture the salient features of the folding process and which may be useful for interpreting and guiding experiments? Here, we present three different approaches to the first question,...
