The administration of compounds through the skin is a complex and challenging process, due to the barrier primarily provided by the skin outermost layer, the stratum corneum (SC). The SC consists of corneocytes embedded in an intercellular lipid matrix (ILM) composed mainly of ceramides, cholesterol, and free fatty acids, organized in a complex lamellar structure with different periodicities and late...
This work aims to develop a bio-based fibrous material that is able to adsorb and degrade chemical and biological hazardous agents. Thus, cellulosic fabrics (flax) were functionalized with chitosan (CS) and poly(ethylene oxide) (PEO) electrospun nanofibers doped with titanium dioxide (TiO2) and cerium dioxide (CeO2) nanoparticles (NPs). The electrospray deposition of these NPs was also tested. The TiO2 N...
“Enfermidades da língua”, publicado em 1759, aparentemente quer retirar cerca de 4000 palavras e expressões da língua portuguesa. Porém, na nossa opinião, esta é uma estratégia para nomear o proibido, fugindo à Inquisição nos tempos do famoso Marquês de Pombal. A obra permite assim, para além de outras informações linguísticas, conhecer provérbios e expressões idiomáticas que estavam em uso há cerca de 3...
From scientific and technological points of view, poly(vinylidene fluoride), PVDF, is one of the most exciting polymers due to its overall physicochemical characteristics. This polymer can crystalize into five crystalline phases and can be processed in the form of films, fibers, membranes, and specific microstructures, being the physical properties controllable over a wide range through appropriate chemi...
Renewable energy sources require efficient energy storage systems. Lithium-ion batteries stand out among those systems, but safety and cycling stability problems still need to be improved. This can be achieved by the implementation of solid polymer electrolytes (SPE) instead of the typically used separator/electrolyte system. Thus, ternary SPEs have been developed based on poly(vinylidene fluoride-co-hex...
