Pourbaix diagrams are constructed from the three, and only three, types of straight line relationships, which result from the analysis of the possible chemical and. We compare our DFT Pourbaix diagrams with directly observed electrochemical, geological, and biomagnetic phenomena on mTM-based metals and compounds to comprehensively demonstrate the high accuracy of our fully ab initio scheme. Ground state of the electron gas by a stochastic method. Rodriguez, D. Corrosion of metals MB.
