Furan-containing biobased polyurethane nanofibers: A new versatile and green support clickable via Diels-Alder reaction
(Elsevier, 2022-09)
A new biobased polyurethane formulation containing furan was synthesized and subsequently functionalized and de-functionalized via Diels-Alder and retro Diels-Alder reactions. Furan was inserted in the backbone polymer ...
Effect of the biobased polyols chemical structure on high performance thermoset polyurethane properties
(Elsevier, 2022-12)
The sustainability of the polymeric materials has become a fundamental challenge; therefore, the development of new biobased formulations has gained increasing interest. Thermoset polyurethanes (PURs) present high performance ...
Study of the influence of reutilization ionic liquid on lignin extraction
(Elsevier, 2015-04-09)
The development of green techniques for biomass processing and fractionation is crucial from the point of view of sustainability and environmental protection. Lignin is the second most abundant bio-renewable material on ...
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 ...
Study of a renewable capping agent addition in lignin base catalysed depolymerisation process
(Elsevier, 2020-07-13)
The aim of this work was to study the influence of a renewable capping agent (CA) in the production of monomeric compounds from the depolymerization of an organosolv lignin (Pinus radiata) by a base catalyzed depolymerization ...
Valorization of cheese whey: closing the loop from protein extraction to whey protein film composting
(RSC, 2024)
Whey protein extracted from cheese-making by-products was analysed as a potential alternative for both food waste valorisation and food packaging waste reduction. Whey protein was ultrafiltered from local cheese whey and ...
5-Methoxymethyl furfural production by acid heterogeneous catalytic etherification of 5-hydroxymethyl furfural
(Elsevier, 2024-01)
The use of non-edible raw materials from agriculture as a form of biomass to obtain carbon-based compounds is the most viable solution to replace fossil resources. Within this, 5-hydroxymethyl furfural (HMF) is a platform ...
Solvent and catalyst effect in the formic acid aided lignin-to-liquids
(Elsevier, 2018-09-13)
[EN] The effect of the type of solvent, ethanol or water, and a Ru/C catalyst were studied in the formic acid aided lignin conversion. The best results were obtained in the presence of the Ru/C catalyst and using ethanol ...
Effect of Sulphate-Reducing Bacteria Activity on the Performance of Thermally Sprayed Aluminium and Polyurethane Coatings
(MDPI, 2024-03-06)
In the present work, we studied whether the exposure of synthetic seawater with anaerobic sulphate-reducing bacteria (SRB) on some steel samples generates a bacterial biofilm in their surfaces. Bare steel belonging to a ...
Kraft and organosolv lignin-activated carbon composites for supercapacitor electrode materials
(Elsevier, 2024-03)
Lignin-activated carbon (AC) composites were employed as electrode active materials to develop more environmentally friendly Supercapacitor (SC) materials with enhanced properties. This way, the hydroquinone/quinone moieties ...
