Magnetic nanocomposites based on poly(styrene-b-butadiene-b-methyl methacrylate) and modified Fe2O3 nanoparticles
(Elsevier, 2016-03-25)
In this work an ABC-type triblock copolymer has been used to prepare magnetic organic/inorganic nanocomposites by selectively placing maghemite nanoparticles modified on their surface with different polymer brushes. As ...
Lignin oxidation and depolymerisation in ionic liquids
(RSC, 2015-09)
The depolymerisation of lignin directly in the black liquor was studied, comparing two ionic liquids as extracting solvents (butylimidazolium hydrogen sulphate and triethylammonium hydrogen sulphate), under oxidising ...
Liquefaction of Kraft lignin using polyhydric alcohols and organic acids as catalysts for sustainable polyols production
(Elsevier, 2019)
[EN]In this work, three different organic acid catalysts, (acetic acid, lactic acid and citric acid), are proposed as an
alternative to common catalysts used in the liquefaction process of Kraft lignin. These organic acids ...
Nanocomposites based on nanostructured PI-b-PMMA copolymer and selectively placed PMMA-modified magnetic nanoparticles: Morphological and magnetic characterization
(Elsevier, 2016-02)
Hybrid organic/inorganic nanocomposites with magnetic properties have been prepared,
based on nanostructured PI-b-PMMA block copolymer and selectively placed magnetic
Fe2O3 nanoparticles. Magnetic nanoparticles have been ...
Effect of different aqueous synthesis parameters on the size of CdSe nanocrystals
(Springer Nature, 2012-06-30)
The variation of CdSe nanoparticle size as a function of synthesis conditions is presented. Cadmium sulphate (CdSO4), cadmium chloride (CdCl2) and sodium selenosulphate (Na2SeSO3) solutions were used as precursors. ...
Kraft lignin as filler in PLA to improve ductility and thermal properties
(Elsevier, 2015-10)
[EN] Kraft lignin (KL) and acetylated Kraft lignin (AKL) were used as filler for the elaboration of composites
with poly(lactic acid) (PLA) in different concentrations (0.5, 1, 5, 10 and 20%) by extrusion method at
200 ...
Enhanced stability of photo-induced anisotropy due to intermolecular interactions in an azo-prepolymer confined in block copolymer
(Elsevier, 2013-02-08)
Many efforts in the field of azobenzene-containing polymers are concentrated on exploring new material concepts to obtain efficient and stable photo-induced anisotropy. Here, an easy approach to improve the birefringent ...
High-Performance Magnetic Activated Carbon from Solid Waste from Lignin Conversion Processes. 1. Their Use As Adsorbents for CO2
(ACS Publications, 2017-03-09)
[EN] Lignin is naturally abundant and a renewable precursor with the potential to be used in the production of both chemicals and materials. As many lignin conversion processes suffer from a significant production of solid ...
Hemicelluloses obtaining from rapeseed cake residue generated in the biodiesel production process
(2010-03-25)
[EN]The processing of rapeseed oil seeds for biodiesel production generates huge amounts of lignocellulosiccake residue mainly composed by cellulose, hemicelluloses and lignin. In this work, the valorisation ofthese ...
Influence of morphology of zirconium-doped mesoporous silicas on 5-hydroxymethylfurfural production from mono-, di- and polysaccharides
(Elsevier, 2020-02-21)
[EN] Different zirconium-doped mesoporous silicas (Zr-KIT-6, Zr-SBA-15, Zr-MCM-41 and Zr-HMS) were synthesized and evaluated in the glucose dehydration to 5-hydroxymethylfurfural (HMF). A Si/Zr molar ratio of 5 was chosen ...
