Physicochemical analysis of Permian coprolites from Brazil
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2018In this paper we performed the study of two coprolites (fossilized feces) collected from the exposed levels of the Pedra de Fogo Formation, Parnaiba Sedimentary Basin, and Rio do Rasto Formation, Paraná Sedimentary Basin, both of the Palaeozoic era (Permian age).

Physicochemical Analysis of Superconducting Systems
1973The study of binary, ternary, and more complex systems of chemically-active refractory metals, including “hard” “superconductors” only became possible in the second half of the present century after pure, rare, and refractory metals had been prepared and the apparatus and techniques developed for their vacuum melting, “neutral” melting, and heat ...

Problems in the physicochemical analysis of solids
Russian Journal of Physical Chemistry A, 2014Features of the physicochemical analysis of solids at low temperatures in nonequilibrium states due to diffusion resistance during the mixing of atoms are considered from the standpoint of statistical thermodynamics. It is shown that the existing approach to interpreting the state of solids, which is based on classical thermodynamics, does not ...

Physicochemical analysis in materials science
Russian Journal of Inorganic Chemistry, 2010The concepts of a substance, phase, component, and directed synthesis strategy are discussed. Attention is paid to nonstoichiometry and defect composition. The following features of P-T-x phase diagrams are considered: highest melting point of a nonstoichiometric compound (T m, AB max ); noncoincidence between the solid-, liquid-, and vapor-phase ...
