Prize #1 Lucile FEGER (GREMAN, Tour)
Contrôle de la conductivité thermique par un champ électrique dans BaTiO3 et ses dérivés

Heat flux as a new information vector
What if heat became the new current? Her work explores the thermal conductivity of the ferroelectric material BaTiO₃ in various forms and under an electric field, contributing to the development of phononics, which harnesses phonon flux as carriers of information.
The thesis work « Contrôle de la conductivité thermique par un champ électrique dans BaTiO3 et ses dérivés » has been done at GREMAN Tours.

Prize #2 Silvère PANISSET (LMGP, Grenoble)

Electrodes à Oxygène en Couches Minces Nano-structurées pour Dispositifs Electrochimiques à Oxyde Solide : Optimisation du Dépôt, Caractérisation et Modélisation

Emerging oxygen ion battery technologies
This thesis focuses on the design and optimization of nano-engineered thin film oxygen electrodes (≤ 1000
nm) based on La2NiO4+δ and LaPrNiO4+δ, deposited by PIMOCVD.
Combining advanced characterization, modelling, and novel in situ diagnostics, the work advances their application in micro solid oxide cells and explores their potential in emerging oxygen ion battery technologies.
