Guimarães, Aracelle de Albuquerque SantosThe aim of this work was to prepare and characterize chitosan (CS) and poly (vinyl alcohol) (PVA) hydrogels, and different CS / PVA compositions, with and without addition of clay (AN) and Ibuprofen (IBU) for a dermal matrix, to be tested as a drug carrier vehicle and used as a wound dressing. They were prepared by the solvent evaporation method and analyzed qualitatively by the visual aspect, them they were ch...
Desenvolvimento de blendas de PLA e polímeros do glicerol e nanocompósitos com ...
Silva, Amanda Vieira daBiodegradable polymers have been widely studied due to the social quest to reduce the dependence of fossil products. Poly(lactic acid) - PLA is highlighted because it is biodegradable and has a high modulus of elasticity and stiffness, however low thermal stability, flexibility and impact resistance that limit its use. In this work, blends with PLA and glycerol polymers, and nanocomposites with cellulose nanowh...

Conversor CC-CC trifásico Push-pull de alto ganho alimentado em corrente
Costa, André Elias Lucena daThis paper presents a new three-phase current-fed Push-Pull DC-DC converter. The proposed converter has reduced size when compared with single-phase topologies and has a simplified gate drive circuit with switches connected to the same reference. When compared with three-phase topologies presented in the literature, the proposed converter has a higher gain and a transformer with reduced leakage inductances, sin...
