Biocompatible Bacterial Cellulose-Poly(2-hydroxyethyl methacrylate) Nanocomposite Films
(Hindawi Publishing Corporation, 2013-07)
A series of bacterial cellulose-poly(2-hydroxyethyl methacrylate) nanocomposite films was prepared by in situ radical polymerization of 2-hydroxyethyl methacrylate (HEMA), using variable amounts of poly(ethylene glycol) ...
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 ...
Strain sensitive conductive polyurethane foam/graphene nanocomposites prepared by impregnation method
(Elsevier, 2017-03-14)
Se prepararon nanocompuestos de espuma de poliuretano conductores mediante la incorporación de flakes de grafeno. Los flakes de grafeno se obtuvieron a partir de grafito por el método de exfoliación líquida en N metilpirrolidona ...
Tailoring Mechanical Properties of Rigid Polyurethane Foams by Sorbitol and Corn Derived Biopolyol Mixtures
(ACS, 2015-10-28)
Sorbitol arises to be a strong candidate for renewably sourced polyol synthesis. Moreover, processes for extracting sorbitol directly from cellulosic materials are effective, and materials such as agroforestry residues ...
Base catalysed depolymerization of lignin: Influence of organosolv lignin nature
(2014-07)
Three different lignins obtained from olive tree pruning by organosolv processes
(acetosolv, formosolv and acetosolv/formosolv) were depolymerized by alkaline hydrolysis in a batch reactor to produce high value added ...
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 ...
Economic analysis of a biorefinery process for catechol production from lignin
(Elsevier, 2018-10)
Recently, the valorization of the lignin fraction in the biorefinery scheme is getting more and more attention as the use of this component for the production of bio-based chemicals is crucial for the success of the integral ...
Analysis of the effect of temperature reaction time on yields, compositions and oil quality in 3 catalytic and non-catalytic lignin solvolysis in a formic acid/water media using experimental design.
(Elsevier, 2017-03-01)
[EN] The catalytic solvolysis of Norway spruce (Picea abies L.) lignin in a formic acid/water media was explored at different temperatures and reaction times (283–397 °C and 21–700 min, respectively). Non-catalyzed experiments ...
Depolymerization of different organosolv lignins in supercritical methanol, ethanol and acetone to produce phenolic monomers
(ACS, 2015-12-18)
Olive tree pruning was delignified by organosolv processes (acetosolv, formosolv and acetosolv/formosolv) to extract different lignins. The obtained lignins (acetosolv lignin (AL), formosolv lignin (FL) and acetosolv/formosolv ...
