My research interests are mainly in physical and applied chemistry of novel materials and their mixtures with other fluids and in particular on the relationship between chemical structure and physical properties. The objectives of our works focus on the development of in-house properties databanks, the design of novel and original experimental apparatuses and physical models able to access and then to predict properties with view to understanding the physic chemical properties of novel materials and developing viable chemical engineering processes. The group has strong collaborations with external academic groups including Magdalena Bendova (Institute of Chemical Process Fundamentals, Prague), Margarida Costa-Gomes (Blaise Pascal University, Clermont-Ferrand II), Alfonso Pensado (University of Leipzig, Leipzig), and Mérièm Anouti (François Rabelais University, Tours).
It is well known that the influence of thermodynamics on industrial processes is often very complex and required in solving chemical engineering problems. To resolve this problem, one of our main objectives is to investigate experimentally physcial properties of pure materials in order to provide reference data, and to understand the relationship between chemical structure and physical properties.

Our objectives include also the understanding of their physical properties and phase behaviors in mixtures with gases, conventional solvents, or molten salts by using both common and designed in-house experimental techniques to access to their structure and interactions at a molecular level.

Dr Margarida Costa Gomes has designed this experimental technique, which is available in the TIM lab.
A better understanding and control of thermodynamic processes is also link to the development of predictive tools able to access to the specific properties over wide ranges of temperature and pressure. To provide these tools, our strategy is to build up, at first, large physical properties databanks for desired properties, which include results already available within the literature, and those measured in-house. Based on these databanks, advanced predictive methodologies such as group contribution models (GCM), equations of state, or activity coefficients models are then developed, tested and used in order to provide knowledge of unmeasured properties.
