Abstract:
La fonctionnalisation des biomatériaux est une stratégie probante et prometteuse développée pour favoriser l’intégration de biomatériaux dans un organisme vivant. Le dépôt de films multicouches de polyélectrolytes est une méthode de fonctionnalisation de surfaces particulièrement adaptée au recouvrement d’implants. Ces surfaces modifiées pourront ainsi interagir avec leur environnement biologique. Au cours de ce travail de thèse, nous avons développé un nouveau revêtement, à base de composés naturels, capable de recouvrir plusieurs types de surfaces. De plus, ces revêtements originaux peuvent

Abstract:
This thesis discusses the investigation and utilization of a new promising thin-film material, liquid crystal polymer (LCP), for microwave and millimeter-wave (mm-wave [>30 GHz]) components and packages. The contribution of this research is in the determination of LCP's electrical and mechanical properties as they pertain to use in radio frequency (RF) systems up to mm-wave frequencies, and in evaluating LCP as a low-cost substrate and packaging material alternative to the hermetic materials traditionally desired for microwave circuits at frequencies above a few gigahertz (GHz).

Abstract:
During the recent years, the space technology trend was pointing towards the miniaturization of all its components in order to achieve a smaller and lightweight satellite with low power and low noise components. A possible solution to this request can be given by the anisotropic magnetoresistance (AMR) based sensors which present good miniaturizability and low power consumption. The objective of this thesis is to study and characterize a Planar Hall E ect Bridge (PHEB) AMR sensor in order to understand if this type of technology can meet the strict performance requirements imposed for a space

Abstract:
Polyelectrolyte multilayer capsules fabricated by layer-by-layer (LbL) self-assembly technique consistsing of core-shell structure have emerged as potential drug delivery systems along with their applications in micro-reactors, cosmetics, vaccines and antimicrobial coatings. Various ligands and stimuli responsive entities can be incorporated into the core and shell of the capsules for targeted delivery and/or controlled release applications. Though multilayer capsules have been studied extensively as delivery systems, their utility for encapsulation of hydrophobic drugs and multiple drugs have
