    "We who are in the field of thermodynamics and thermochemistry are most fortunate in working in a science that is basic to the behaviour of all matter in the universe"

Research Fields top

1. Solid State Thermodynamics. High-Temperature (700 - 1600 oC) Phase Transformations.
  • Thermodynamics of the condensed systems in pure phases and at the equilibrium between phases. Phase diagrams.
  • Thermodynamics of micro and nanostructured materials with special electrical and magnetic properties (semiconductors, mixed conductors, SOFC components, feroics, multiferoics, catalysts, composite materials)
  • -Thermodynamics of the nonstoichiometric oxides (thermodynamics of the defect structure in the transitional metal oxides; experimental measurements and validation of the theoretical models)
  • Applications: Solid electrolytes; Electrochemical sensors; SOFC with solid electrolyte; Nanomedicine)

2. Vapour-Liquid and Liquid-Liquid Phase Equilibria. Termophysical Properties.

  • Vapour-liquid equilibria (VLE) measurements for organic mixtures at low and normal pressures; application to separation processes
  • Gas solubility measurements in high boiling point liquids; application to supercritical fluid technology
  • Vapour-liquid equilibria measurements in systems with chemical reaction; application to reactive separation processes
  • Liquid-liquid equilibria (LLE) measurements for binary and ternary systems at normal pressure
  • Thermophysical properties measurements for pure liquids and mixtures at atmospheric and high pressures
  • Thermodynamic modelling and processing of experimental thermodynamic data
  • Thermodynamic properties of aqueous electrolyte solutions with or without organic component. Modelling of the activity coefficients

3. Thermochemical characterization of the biological interest compounds.

  • Thermochemical characterization of the biological interest compounds (amino-acids, peptides, proteins etc) as basical compounds and models for a better understanding of living organisms
  • The thermochemistry of gamma irradiated biological interest compounds (amino-acids)
  • Thermodynamics of binding interactions (ligand – proteins, ligand-cyclodextrin)
  • Applications in Nanomedicine
