Abstract:

The main purpose of this project is the use of a high accuracy photopyroelectric (PPE) calorimetry to study thermal properties of magnetic nanofluids and their changes as a function of the relevant parameters of the nanofluid (carrier liquid, surfactant, type, size and concentration of nanoparticles). The research is focused on the water-based nanofluids with Fe3O4, gamma-Fe2O3 and CoFe2O4 type of nanoparticles, covered with polymer as stabilizer. Through the PPE calorimetry one can obtain with high accuracy all static and dynamic thermal parameters (by directly measuring two, the fundamental ones: thermal diffusivity and effusivity) of a liquid sample. The main originality of this project consists in the fact that, due to the increase of the sensitivity of the PPE investigations, it is possible to study, through calorimetric techniques, intimate structural processes, associated with small variations of the thermal parameters, as it is specific to magnetic nanofluids too. Water-based magnetic nanofluids are currently investigated in order to develop new magnetically controlled drug delivery systems and magnetic separation methods of biomaterials. The project is organized in two main stages: (i) the increase of the performances of the PPE calorimetry (through theoretical and experimental optimizations) up to an accuracy and reproducibility of 96% and (ii) the study of the thermal properties of the magnetic nanofluids as a function of the relevant parameters of the nanofluid.

Abstract:

In this project we proposed to perform Earth-like mantle convection studies. The novelty of our approach relies on the fact that the internal heating is produced by microwave (MW) absorption.
