A sustainable methanol-based solvent exchange method to produce nanocellulose-based ecofriendly lubricants
Roman, Claudia; García Morales, Moisés
; Eugenio, María Eugenia; Ibarra, David; Martín Sampedro, Raquel; Delgado Canto, Miguel Ángel (Elsevier, 2021)
A prospective methodology aimed to develop totally sustainable oleogels with potential application in lubrication is reported. Oleogels were prepared with cellulose nanofibrils from elm pulps in castor oil. Even at a ... -
Eco-Friendly Oleogels from Functionalized Kraft Lignin with Laccase SilA from Streptomyces ipomoeae: An Opportunity to Replace Commercial Lubricants
Domínguez, Gabriela; Blánquez, Alba; Borrero López, Antonio María; Valencia Barragán, Concepción; Eugenio, María Eugenia; Arias, María Enriqueta; Rodríguez, Juana; Hernández, Manuel (American Chemical Society, 2021)
This work demonstrates the usefulness of SilA laccase from Streptomyces ipomoeae to functionalize Kraft lignin to be used as a thickener in the preparation of biodegradable oleogels for lubricating purposes. First, ... -
Emulsion Stabilization by Cationic Lignin Surfactants Derived from Bioethanol Production and Kraft Pulping Processes
Yuliestyan, Avido; Partal López, Pedro; Navarro Domínguez, Francisco Javier; Martín Sampedro, Raquel; Ibarra, David; Eugenio, María Eugenia (MDPI, 2022-07)
Oil-in-water bitumen emulsions stabilized by biobased surfactants such as lignin are in line with the current sustainable approaches of the asphalt industry involving bitumen emulsions for reduced temperature asphalt ... -
Influence of Cellulose Characteristics on Pyrolysis Suitability
Eugenio, María Eugenia; Ruiz Montoya, Mercedes; Martín Sampedro, Raquel; Ibarra, David; Díaz Blanco, Manuel Jesús (MDPI, 2021)
: Cellulose is the most abundant component of biomass and the one that requires the most activation energy (Ea) for pyrolysis. In this study, the dependence of Ea on the intrinsic cellulose characteristics, such as the ... -
Populus alba L., an Autochthonous Species of Spain: A Source for Cellulose Nanofibers by Chemical Pretreatment
Ibarra, David; Martín Sampedro, Raquel; Wicklein, Bernd; Borrero López, Antonio María; Valencia Barragán, Concepción; Valdehíta, Ana; Navas, José M.; Eugenio, María Eugenia (MDPI, 2022)
In order to identify new sustainable sources for producing cellulose nanofibers (CNFs), fast-growing poplar (Populus alba L.) wood was evaluated herein. For that purpose, bleached poplar kraft pulp was produced and ...
