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 ... -
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 ... -
Obtaining Fermentable Sugars from a Highly Productive Elm Clone Using Different Pretreatments
Ibarra, David; Martín Sampedro, Raquel; Jiménez López, Laura; Díaz Blanco, Manuel Jesús (MDPI, 2021-04)
The interest of supplying lignocellulosic materials for producing fermentable sugars has recently emerged in order to diminish the negative environmental effects of fossil fuels. In this study, the Ulmus minor clone ... -
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 ...
