Description
The G.E.T.E.F. of the University of Valladolid is a Research Group created in 1994, and whose identity signs would be the following:
We are a group of specialists in the thermodynamic investigation of the equilibria between fluid and condensed phases, who have mainly worked in the study of mixtures and binary and multi-component alloys, within a General Line of work that could be summarized saying that we work in: " Thermodynamic Study of the Balances between Phases that appear in Gas, Liquid and Solid Mixtures ", and which is carried out in five major Specific Research Lines that are indicated below.
Our field of research is multidisciplinary, and covers many different facets. From the experimental point of view, we can say that we have world-renowned experience in the use of a large number of different experimental techniques: High and low temperature thermometry: Calibrated with respect to absolute reference standards. Pressure measurement and vacuum obtaining. Static and dynamic calorimetry of all kinds. Volumetric properties of substances, etc. In summary: Experimental techniques for determining the thermophysical properties of all types of materials.
From the theoretical point of view, we can also say that we have knowledge of Thermodynamics and Molecular Physics -we are professors of Thermodynamics and Statistical Physics at the UVA-, which allow us to develop microscopic models on the behavior of all kinds of complex systems. In summary, we are experts in: Thermodynamics and Statistical Physics of pure substances, mixtures and alloys. Maximum entropy methods (MaxEnt) used in the study of complex systems.
Objective
- From the point of view of basic experimental research.- The determination -in the Group Research Laboratory, or in other national or foreign Laboratories with which we have maintained stable collaborations for more than 20 years- of the equilibria between phases: Liquid -Vapor (ELV), liquid-liquid (ELL) and solid-liquid (ESL), and of the thermodynamic equilibrium properties: Energetic (enthalpies, heat capacities, etc.) or thermal (densities, coefficients of compressibility, etc.) , and transport (viscosities, etc.), of all kinds of binary or multicomponent mixtures or alloys.
- From the point of view of basic theoretical research.- The modeling of the experimental results obtained, and many others that appear in the literature, in order to understand the inter and intramolecular microscopic interactions that take place within the mixtures and alloys; mainly, using the DISQUAC model, in whose development we have collaborated decisively, and we are internationally recognized experts: Also, and in the longer term, apply the knowledge obtained in order to model the behavior of substances of biological and environmental interest (basic molecules that make up DNA, new fuels, etc.), or other types of new materials.
- From the point of view of applied research.- The use of the Group's experimental resources and, in general, of all the basic research carried out to improve all kinds of processes of industrial interest (new design gasoline; prediction of the solubility of polymers from the basic units that form them, improvement of the processes for making and storing bread, ...), collaborate in reducing the polluting effects that some of these processes produce in the environment (effects of improving the change the type of solvent, or the conditions of temperature, pressure, etc., to which it is used, ...), characterize the performance of new materials, etc.
- From the point of view of the training of researchers.- The GETEF is a research group that not only has research capacity (as justified by the more than 70 articles published in journals of recognized international prestige since its foundation), but also a trainer. This is proved by the number of students of Bachelor's, Third Cycle (within the UVA Physics Doctoral Program), and Doctorate (3 members of the Group have defended their Doctoral Thesis since 2000), who continuously join the group. Which we think is worthy of being outstanding; Well, above all, we are teachers and, as such, we must also spend time teaching our students to investigate.
