Alternative chemo-enzymatic treatment for homogeneous and heterogeneous acetylation of wood fibers
(2018-07-18)
Article
Accés obertA new chemo-enzymatic treatment is proposed to produce cellulosic fibers suitable for heterogeneous- or homogeneous-phase acetylation. The procedure included enzymatic (laccase–violuric acid) lignin removal from the precursor ... -
Bacterial cellulose for increasing barrier properties of paper products
(2018-08-07)
Article
Accés obertBacterial cellulose was combined with wood cellulose papers in order to obtain biomaterials with increased barrier properties. For this purpose, different parameters were assessed: two producing bacterial strains ... -
Electrochemical insights on the hydrophobicity of cellulose substrates imparted by the enzymatically-oxidized gallates with increasing alkyl chain length
(2015-06-09)
Article
Accés obertIn this work, we studied the influence of the alkyl chain length in enzymatically-oxidized gallates on the development of hydrophobicity on paper-based materials, and further correlated the obtained effect to the redox ... -
Elucidating the chemical nature of laccase-modified alkyl gallates
(2020-06-12)
Article
Accés obertIn the first part of the present work, relevant findings concerning the laccase (Lacc) activation of alkyl gallates, and its implementation in developing hydrophobic properties on cellulose-based substrates are reported. ... -
Functionalization of cellulosic substrates using a product derived from an enzymatic reaction
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialThe present work describes a new method for the surface functionalization of cellulosic sheets, overcoming the limitations of the traditional treatments, which are usually performed using fibrous suspensions. The method ... -
Occurrence of hydrophobic organic pollutants (BFRs and UV-filters) in sediments from South America
(2013-07)
Article
Accés restringit per política de l'editorialIn the present study the occurrence of emerging hydrophobic organic pollutants in sediment samples from South America (Chile and Colombia) was investigated for the first time. Nineteen Chilean and thirteen Colombian sediment ... -
Tough polymer aerogels incorporating a conformal inorganic coating for low flammability and durable hydrophobicity
(2016-05)
Article
Accés restringit per política de l'editorialBoth inorganic and polymeric aerogels are well-known in the materials field. Inorganic aerogels are generally susceptible to brittle fracture, while polymeric aerogels tend to exhibit low modului and high flammability. To ... -
Using electrochemical methods to study the kinetics of laccase-catalyzed oxidation of phenols
(2018-02-01)
Article
Accés obertIn the present work, the laccase kinetics upon the oxidation process of phenolic compounds was studied using cyclic voltammetry (CV). Several hydroxybenzoic and cinnamic acid compounds were analyzed, and the oxidation ...
