Ingegnerizzazione di nanocosmetici

This study led to the development of new synthesis process to obtain "nano delivery" system like aquasome, suitable to enhance the affinity between dyes and human hair for cosmetic formulation. These systems has been based on silver nanoparticles stabilized by different kind of polymers as PVP or celluloses. The research has been conducted in two steps: the first involved the study and optimization of the nano delivery system synthesis conditions as concentrations, pH and temperature. The second concerned the preparation of a stable, low hazard and with antibacterial and antifungal properties formulation containing the aquasome and a colorant already used in cosmetics (i.e. Basic Red 51) for hair dyeing application.

On the influence of polymeric nanofibers in laminated composite materials. Studio dell'influenza di nanofibre polimeriche in materiali compositi laminati

During the last years an increased interest about the reinforcement of laminated composites by means of polymeric nanofibers has been growth. During this master-degree-thesis work, unidirectional and plane-textile composites have been interleaved with Nylon 6.6, PCL and mixed (Nylon 6.6+PCL) nanofibrous mats and the DCB (mode I interlaminar fracture toughness), ENF (mode II interlaminar fracture toughness and DMA (damping capability) tests have been performed. Regarding the interlaminar fracture toughness, marked increases have been recorded; while further investigation about damping capability is requested.
