Cellulose Nanocrystal Membranes as Excipients for Drug Delivery Systems
(MDPI, 2016-12-12)
In this work, cellulose nanocrystals (CNCs) were obtained from flax fibers by an acid hydrolysis assisted by sonochemistry in order to reduce reaction times. The cavitation inducted during hydrolysis resulted in CNC with ...
Functionalization of Cellulose Nanocrystals in Choline Lactate Ionic Liquid
(MDPI, 2016-06)
Cellulose nanocrystals (CNCs) are valuable nanomaterials obtained from renewable resources. Their properties make them suitable for a wide range of applications, including polymer reinforcement. However, due to their highly ...
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 ...
Willow lignin oxidation and depolymerization under low cost ionic liquid
(ACS, 2016-05-10)
Willow biomass was subjected to different pretreatmentconditions with triethylammonium hydrogen sulfate as solvent, andthe produced lignin solutions were treated by oxidation either homo-geneously using H2O2as oxidant or ...
