Effect of the photocatalytic activity of TiO2 on lignin depolymerization
(Elsevier, 2013-05)
Lignin is a good candidate for photocatalytic cracking due to the presence of hydroxyl groups. The photocatalytic cracking reaction involves TiO2 as heterogeneous catalyst.
In the present work lignin obtained by two ...
Azopolymer film as an actuator for organizing multiwall carbon nanotubes
(Elsevier, 2017-01-25)
In this work we show the feasibility of using an azopolymer as an actuator to induce nano- and
microscale movements controlled with light from the far field. We study azopolymers and their interaction
with multi-walled ...
Chicken feathers as a natural source of sulphur to develop sustainable protein films with enhanced properties
(Elsevier, 2017-08-05)
In this work, the effect of hydrolyzed keratin on the properties of soy protein-based films was analyzed when different manufacture processes were employed. It is widely known that the processing method selected can affect ...
Block copolymer concentration gradient and solvent effects on nanostructuring of thin epoxy coatings modified with epoxidized styrene-butadiene-styrene block copolymers
(ACS, 2012-01-27)
The gradient on block copolymer concentration through film thickness as well as the effects of casting solvents used on the nanostructuring of a thermosetting epoxy coating modified with an epoxidized poly(styrene-b-buta ...
Characterisation of bark of six species from mixed Atlantic forest
(Elsevier, 2019-10)
[EN] Bark is one of the most available by-product derived from the wood-base industry because of the total volume of the tree that comprised. This study aimed at evaluating the chemical composition of barks of six typical ...
Effect of different organosolv treatments on the structure and properties of olive tree pruning lignin
(Elsevier, 2014-05-25)
Different organosolv processes (acetosolv, formosolv and acetosolv/formosolv) were applied to extract lignin from olive tree pruning. Obtained lignins were characterized by several methods to determine their composition, ...
Effect of CdSe nanoparticle addition on nanostructuring of PS-b-P4VP copolymer via solvent vapour exposure
(Elsevier, 2013-10-28)
The surface morphology of poly(styrene-b-4 vinyl pyridine) (PS-b-P4VP) diblock copolymer thin films
after solvent vapor annealing has been studied. Morphological features can be switched upon exposure
to vapors of a ...
Flexible polyurethane foams based on 100% renewably sourced polyols
(Elsevier, 2014-10-5)
Since polyol is one of the major components in polyurethane foam synthesis, introducing renewably
sourced polyols in the foam formulation leads to materials with high renewable carbon content. A series of
flexible ...
Effect of different hemicelluloses characteristics on film forming properties
(Elsevier, 2013)
Hemicelluloses are known to have good gas barrier properties makes them of interest to film applications.
Corn cob, cotton waste, olive, apple tree pruning, pepper and chilli wastes were used as hemicelluloses
sources ...
Effect of alkaline and autohydrolysis processes on the purity of obtained hemicelluloses from corn stalks
(Elsevier, 2012)
[EN]A study of the potential of autohydrolysis and alkaline extraction processes from corn stalks was performed
for high purity hemicellulose extraction. The influence of process parameters on the purity of
obtained ...
