Characterisation of Films Based on Exopolysaccharides from Alteromonas Strains ...
Concórdio-Reis, Patrícia; Pereira, João R.; Delgado Alves, Vitor; Nabais, Ana R.; Neves, Luísa A.; Marques, Ana C.; Fortunato, Elvira; Moppert, XavierThis work assessed the film-forming capacity of exopolysaccharides (EPS) produced by six Alteromonas strains recently isolated from different marine environments in French Polynesia atolls. The films were transparent and resulted in small colour alterations when applied over a coloured surface (ΔEab below 12.6 in the five different colours tested). Moreover, scanning electron microscopy showed that the EPS film...
Poly(ethylene glycol) Diacrylate Iongel Membranes Reinforced with Nanoclays for...
Nabais, Ana R.; Francisco, Rute O.; Delgado Alves, Vitor; Neves, Luísa A.; Tomé, Liliana C.Despite the fact that iongels are very attractive materials for gas separation membranes, they often show mechanical stability issues mainly due to the high ionic liquid (IL) content ( 60 wt%) needed to achieve high gas separation performances. This work investigates a strategy to improve the mechanical properties of iongel membranes, which consists in the incorporation of montmorillonite (MMT) nanoclay, from 0...
