To prevent consequences of damage in case of accident, some barriers of pre-stressed concrete are included in the nuclear power plant structures. Hence, to insure the nuclear security, it is important to control these structures. The nuclear accident induces pressure and temperature increases. This...

Synthesis of lead-free (Bi0,5Na0,5)TiO3 thin film by RF magnetron sputtering

Ahmad Hamieh, Freddy Ponchel, Denis Remiens, Sophie Barrau

This work concerns the growth of (Bi0,5Na0,5)TiO3 on Si/SiO2/LNO by RF magnetron sputtering. We observed, for the first time on BNT thin films, reactions that destroy the film. This behavior is associated to sodium or sodium oxide segregation. After an extensive description of the sodium impact...

The control of the propagation of elastic waves relies mainly on the design of artificial medium based on structured materials to obtain an advanced engineering of the dispersion of the propagation. During the thesis, the dispersion of the shear horizontal polarised guided mode (Love mode) in the..., Le contrôle de la propagation des ondes élastiques repose principalement sur la conception de milieu artificiel à base de matériaux structurés pour obtenir une ingénierie avancée de la dispersion de la propagation. Au cours de la thèse, la dispersion du mode guidé de polarisation transverse...
