Journal ArticleDOI
A Study of Chemical Modifications of a Nafion Membrane by Incorporation of Different Room Temperature Ionic Liquids
M.V. Martínez de Yuso,Luísa A. Neves,Isabel M. Coelhoso,João G. Crespo,Juana Benavente,Enrique Rodríguez-Castellón +5 more
TL;DR: In this article, surface and bulk chemical changes in a Nafion membrane as a result of room temperature ionic liquids (RTILs) incorporation were determined by X-ray photoelectron spectroscopy (XPS) and elemental analysis, respectively.
Journal ArticleDOI
Analysis of solvent flux through nanofiltration membranes by mechanistic, chemometric and hybrid modelling
TL;DR: In this article, a set of alternative membrane and solvent descriptors was defined based on published studies, in order to improve the modelling of this system. But the relationship between the solvent flux and the new selected descriptors is currently not known or poorly known at the mechanistic level, alternative chemometric and hybrid chemometric-mechanistic modelling methodologies were adopted.
Journal ArticleDOI
Permeability of cork for water and ethanol.
TL;DR: Experimental evidence shows that both vapors and liquids permeate not only through the small channels across the cells, as in the permeation of gases, but also through the walls of cork cells by sorption and diffusion as in dense membranes.
Journal ArticleDOI
Coupling of nanofiltration and UV, UV/TiO2 and UV/H2O2 processes for the removal of anti-cancer drugs from real secondary wastewater effluent
Raphael Janssens,M.B. Cristóvão,Maria Rosário Bronze,Maria Rosário Bronze,João G. Crespo,V.J. Pereira,Patricia Luis +6 more
TL;DR: In this article, the authors showed that direct photolysis was extremely effective to degrade etoposide and paclitaxel from the secondary effluent as well as from the highly concentrated retentate produced by nanofiltration.
Journal ArticleDOI
Selective recovery of phenolic compounds and carbohydrates from carob kibbles using water-based extraction
Mohammad Almanasrah,Luísa B. Roseiro,Rafal Bogel-Lukasik,Florbela Carvalheiro,Carla Brazinha,João G. Crespo,Mari Kallioinen,Mika Mänttäri,Luís C. Duarte +8 more
TL;DR: In this paper, a two-step water-based extraction of carob kibbles was proposed to obtain significantly separated carbohydrates and polyphenol-rich streams that can be further processed, e.g., in biorefineries or food industries.
