Development of polyurethane cellular foams for the intensification of processes.
Solid foams, made with polyurethane, are well known for their interesting transport properties such as low pressure drop or high specific surface area. However, there are not used as catalytic support due to actual deposition method which causes an alteration of their mechanical properties. First, we used a new deposition method using polydopamine (PDA), a...
STRUCTURE AND PHYSICOCHEMISTRY OF SURFACTANTS, THEIR IMPACTS ON SKIN TOXICITY, BARRIER FUNCTION AND SKIN MOISTURIZATION
Creams, shampoo, soaps, shower gel, all these cosmetics products, daily used; have in common the presence of an essential raw material for their formulation: the surfactant or emulsifier. Those molecules are often in contact with the skin. Indeed, thanks to its special amphiphilic structure, surfactant helps the stabilization of emulsion, the foam production and brings...

New applications of organic nanoparticles: from vectorization of a mixture of active ingredients through the skin to the development of an in vitro diagnostic test for allergy to perfumes
Résumé : Les nanoparticules (NPs) organiques représentent un outil majeur d’innovation en dermatologie. L’objectif de cette thèse a été de développer et d’optimiser des procédés d’encapsulation d’un mélange de molécules odorantes appelé fragrance mix I (FMI) dans des nanoparticules (NPs) de différentes natures: NPs polymères (poly-ε-caprolactone, PCL), ou NPs lipidiques solides (SLNs) (à base de...
Dehydration of Theophylline: Static Gravimetric Analysis and Near Infrared Spectroscopy Monitoring of Vacuum Bed Vacuum Bed Drying
The aim of this work was to investigate the dehydration process of a single static layer of theophylline’s crystals under different hygrothermal conditions and the dehydration-drying process of a stirred bed of theophylline in a vacuum contact dryer in nearly the same hygrothermal conditions. First of all, the hydrated and dehydrated forms of theophylline were...
