Antioxidant activity of phenolic compounds obtained by autohydrolysis of corn residues
(2012-03)
This study aimed to evaluate the effect of autohydrolysis temperature of corn residues in the antioxidant
activity of the phenolic compounds extracted from the liquid phase. The treatments were carried out at
160, 180, ...
Assessment of green approaches for the synthesis of physically crosslinked lignin hydrogels
(Elsevier, 2019-09-28)
Lignin is an excellent candidate to be used as a starting material for hydrogel synthesis due to its highly functional character. The exhaustible character of the fossil resources linked to the increase of plastic residues ...
Fractionation of non-timber wood from Atlantic mixed forest into high-value lignocellulosic materials
(Taylor & Francis, 2020-03-10)
[EN] The forestry industry in the Basque Country has experienced an abandonment of small-sized forests in which native and introduced species tend to regrow if unattended; thus, requiring an intervention under which proper ...
High levels of molecular orientation of surface azo chromophores can be optically induced even in a wet biological environment
(2013-09-18)
We have developed polyelectrolyte multilayer bio-films containing azobenzene chromophores that enhance reversible photo-orientation
upon irradiation with linearly polarized light, to effect surface photoswitching of ...
Hydrogenolysis of 5-hydroxymethylfurfural to produce 2,5-dimethylfuran over ZrO2 supported Cu and RuCu catalysts
(ACS, 2018-07-13)
Glucose dehydration to HMF and its hydrogenolysis to DMF, a suitable biofuel, have been studied using
the same catalysts for both processes. The 10CuZr catalyst shows the highest HMF yield (25.6%) with an acceptable glucose ...
Hybrid and biocompatible cellulose/polyurethane nanocomposites with water-activated shape memory properties
(Elsevier, 2019-04-03)
[EN] Water-activated shape memory bacterial cellulose/polyurethane nanocomposites were prepared by the immersion of bacterial cellulose (BC) wet membranes into waterborne polyurethane (WBPU) dispersions for different times. ...
Hydrogen-rich gas production by continuous pyrolysis and in-line catalytic reforming of pine wood waste and HDPE mixtures
(Elsevier, 2017-01-12)
The continuous pyrolysis-reforming of pine sawdust and high density polyethylene mixtures (25, 50 and
75 wt% HDPE) has been performed in a two-stage reaction system provided with a conical spouted bed
reactor (CSBR) and ...
Morphological study and photo-addressing in poly(styrene-b-butadiene-b-styrene) block copolymers with azobenzene groups and polystyrene matrix: influence of chemical bonding
(2011-01-25)
The main goal of this work was the synthesis of new azo-functionalized block copolymers
(BCP) from epoxidized poly(styrene-b-butadiene-b-styrene) modified with azobenzene
groups by one-step facile reaction between the ...
Multiproduct biorefinery based on almond shells: impact of the delignification stage on the manufacture of valuable products
(Elsevier, 2020-07-22)
In this work, an integral valorisation of almond shells through a biorefinery approach was studied. The three main components of almond shells were extracted, isolated and characterised. The autohydrolysis process permitted ...
Hybrid materials based on azopolymer and sol-gel synthesized silver-containing titanium oxide nanoparticles with photoinduced birefringence
(The Royal Society of Chemistry, 2015-01-28)
The main goal of this work was the development of novel nanocomposite films with different optical
properties. A non-toxic water soluble azopolymer was modified with TiO2 nanoparticles and silver containing TiO2 nanoparticles. ...
