Investigation of catalyst and solvent systems for the catalytic oxidation of Kraft lignin
(Universitat Politècnica de Catalunya / Eidegenössische Technische Hochschule Zürich, 2010)
Master thesis (pre-Bologna period)
Restricted access - author's decisionLignin is one of the main constituents of wood together with cellulose and hemicellulose and can be used as a renewable feedstock for the production of chemicals. Lignin is an amorphous polymer which is separated from ... -
Kinetics of alkaline delignification of hemp and determination of lignin content by thermogravimetry
(2022-04-28)
Article
Restricted access - publisher's policyRaw hemp (Cannabis sativa L.) was subjected to alkaline delignification with the application of NaOH ranging from [0.125M] to [1M] for times from 5 to 480¿min. Lignin contents of the original and delignified samples were ... -
Materials a base de partícules de lignina consolidats amb nanofibres de cel·lulosa: aplicació com a membranes de microfiltració antioxidant
(OmniaScience, 2020-01-31)
Conference report
Open AccessEn aquest treball introduïm un nou tipus de membrana a base de partícules mitjançant la combinació de partícules de lignina (PL) i nanofibres de cel·lulosa (NFC), les quals s’introdueixen en fraccions de petit volum. Les ... -
Particulate coatings via evaporation-induced self-assembly of polydisperse colloidal lignin on solid interfaces
(2018-05-02)
Article
Restricted access - publisher's policyPolydisperse smooth and spherical biocolloidal particles were suspended in aqueous media and allowed to consolidate via evaporation-induced self-assembly. The stratification of the particles at the solid–air interface was ... -
Sonochemically synthesized nanocarriers of antibacterial applications
(Universitat Politècnica de Catalunya, 2022-06-30)
Bachelor thesis
Restricted access - author's decisionLignin, the main natural aromatic polymer, has always attracted the attention of researchers. Lignin, which has a very high efficiency and low cost for biomaterials, constitutes 90% of the choices for biomaterial production. ... -
The delignification of hemp trough the enzyme laccase with mediator HBT: with the addition of a bleaching process of pre-treated hemp with hydrogen peroxide
(Universitat Politècnica de Catalunya, 2021-06-28)
Bachelor thesis
Restricted access - author's decision
Covenantee: Odisee VZWThe purpose of this project was to get a better understanding of the delignification kinetics of the enzyme laccase with the mediator HBT (Hydroxybenzotriazole) on hemp and lignin as a substrate. The end goal was to find ...
