Optimizing lignin cationization: unveiling the impact of reaction conditions th...
Fernandes, Catarina; Gomes, Leandro Cid; Bernin, Diana; Alves, Luís; Rasteiro, Maria Graça; Medronho, Bruno; Varela, CarlaLignin, a natural and abundant biopolymer, holds great potential for cosmetic applications. However, its limited solubility and inherently negative charge restrict its use in certain formulations. This is particularly relevant for hair conditioning, where a positively charged polymer is preferred to effectively treat negatively charged damaged hair. To overcome this limitation, lignin extracted from acacia wood...
Lignin extraction from acacia wood: crafting deep eutectic solvents with a syst...
Fernandes, Catarina; Aliaño González, María José; Gomes, Leandro Cid; Bernin, Diana; Gaspar, Rita; Fardim, Pedro; Reis, Marco S.; Alves, LuísLignin is a complex biopolymer whose efficient extraction from biomass is crucial for various applications. Deep eutectic solvents (DES), particularly natural-origin DES (NADES), have emerged as promising systems for lignin fractionation and separation from other biomass components. While ternary DES offer enhanced fractionation performance, the role of each component in these mixtures remains unclear. In this ...
Levulinic acid-based “green” solvents for lignocellulose fractionation: on the ...
Melro, Elodie; Riddell, Alexander; Bernin, Diana; Rosa Da Costa, Ana; Valente, Artur J. M.; Antunes, Filipe E.; Romano, Anabela; Norgren, MagnusThe high potential use of lignin in novel biomaterialsand chemicalsrepresents an important opportunity for the valorization of the mostabundant natural resource of aromatic molecules. From an environmentalperspective, it is highly desirable replacing the hazardous methodscurrently used to extract lignin from lignocellulosic biomass anddevelop more sustainable and environmentally friendly approaches.Therefore, i...
