El ánimo de este trabajo de investigación ha sido sumarse a las opiniones más optimistas en el campo de la nanotecnología y tratar de hacer un aporte en el desarrollo de una más de las piezas de su engranaje; la elaboración ...
Assessment of Biomass Energy Potential and Forest Carbon Stocks in Biscay (Spain)
(MDPI, 2016-03)
The aim of this research is to identify, quantify and characterize the potential available forest biomass of Pinus radiata D. Don and Eucalyptus globulus Labill. across Biscay province in northern Spain. In order to do ...
Water Uptake Behavior and Young Modulus Prediction of Composites Based on Treated Sisal Fibers and Poly(Lactic Acid)
(MDPI, 2016-05)
The main aim of this work was to study the effect of sisal fiber surface treatments on water uptake behavior of composites based on untreated and treated fibers. For this purpose, sisal fibers were treated with different ...
An Alternative Approach for the Incorporation of Cellulose Nanocrystals in Flexible Polyurethane Foams Based On Renewably Sourced Polyols
(Elsevier, 2016-11-16)
Este trabajo analiza tanto el efecto de los nanocristales de celulosa en las propiedades finales de espumas flexibles de poliuretano basadas en castor oil y maíz, sino que además se realiza un análisis en profundidad sobre ...
Cellulose nanocrystals reinforced environmentally-friendly waterborne polyurethane nanocomposites
(Elsevier, 2016-10)
Focusing on eco-friendly materials, cellulose nanocrystals (CNC) have gained attention as nanoreinforcement due to their exceptional properties conferred by the elevated length/diameter aspect ratio and high specific ...
Combined Mesoscale/Experimental Study of Selective Placement of Magnetic Nanoparticles in Diblock Copolymer Films via Solvent Vapor Annealing
(ACS Publications, 2016-03-16)
We present a combined theoretical/experimental study to investigate the effect of selective solvent vapor annealing treatment on the obtainment of highly ordered morphologies of symmetric poly(styrene-b-methyl methacrylate) ...
Lignin-ester derivatives as novel thermoplastic materials
(RSC, 2016)
[EN] Spruce and eucalyptus lignins isolated by an organosolv process and lauroyl chloride were used as raw material for the synthesis of lignin-ester derivatives. The obtained products presented new and interesting properties ...
Modification of Eucalyptus and Spruce organosolv lignins with fatty acids to use as filler in PLA
(2016-05-09)
Spruce (softwood) and Eucalyptus (hardwood) woods were used as raw material for lignin extraction by
organosolv process. Chemical, structural and thermal characterizations of the extracted lignin samples have
been performed ...
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 ...
