Oil Production by Pyrolysis of Real Plastic Waste
(MDPI, 2022-01-29)
The aim of this paper is for the production of oils processed in refineries to come from the pyrolysis of real waste from the high plastic content rejected by the recycling industry of the Basque Country (Spain). Concretely, ...
Characterization of Wood‑based Industrial Biorefinery Lignosulfonates and Supercritical Water Hydrolysis Lignin
(Springer, 2020-11)
Understanding the properties of any particular biorefinery or pulping residue lignin is crucial when choosing the right lignin for the right end use. In this paper, three different residual lignin types [supercritical water ...
Polyurethane Wood Adhesives Prepared from Modified Polysaccharides
(MDPI, 2022-01-28)
This study investigated the performance of polyurethane adhesives prepared with various combinations of wheat starch that had been modified by isophorone diisocyanate (MS), two polyol types (1,3-propanediol (PD) and glycerol ...
Advances in Waterborne Polyurethane and Polyurethane-Urea Dispersions and Their Eco-friendly Derivatives: A Review
(MDPI, 2021-01-27)
Polyurethanes and polyurethane-ureas, particularly their water-based dispersions, have gained relevance as an extremely versatile area based on environmentally friendly approaches. The evolution of their synthesis methods, ...
Development of an electrical resistance-based corrosion monitoring system for offshore applications.
(2022-04-28)
El objetivo principal de la tesis es el desarrollo de un sistema de monitorización remota de la corrosión para estructuras off-shore (eólica y oil & gas). Mediante este sistema se pretende medir en forma remota la velocidad ...
3D printing of customized all-starch tablets with combined release kinetics
(Elsevier, 2022-06-25)
[EN] Starch-based tablets with tailored releases were prepared by 3D printing using a hydrophobic drug. The importance of the origin of the excipient in the inks and tablets was analyzed. Besides, the effect of the geometry ...
Polyhydroxybutyrate (PHB) produced from red grape pomace: Effect of purification processes on structural, thermal and antioxidant properties.
(Elsevier, 2022-09)
Red grape pomace was used as a source for poly(3-hydroxybutyrate) (PHB) production, which was then subject to a range of purification processes. The different PHB biopolymers were characterized for chemical structure, ...
Click chemistry: an efficient toolbox for the design of chitosand-based hydrogels for biomedicine
(2020-05-28)
The present thesis was focused on the development of new gel-type biomaterials form chitosan withexcellent stimuli-responsive properties using different click reactions. To this end, in the first place,chitosan was endowed ...
Tailoring physicochemical properties of collagen-based composites with ionic liquids and wool for advanced applications
(Elsevier, 2022-06)
Wool, choline dihydrogen phosphate ([Ch][DHP]) or choline serinate ([Ch][Seri) ionic liquids (ILs) were incorporated into native collagen formulations and films were prepared by compression molding. Scanning electron ...
Characterization of the Compounds Released in the Gaseous Waste Stream during the Slow Pyrolysis of Hemp (Cannabis sativa L.)
(MDPI, 2022-04-27)
This study aims to characterize and valorize hemp residual biomass by a slow pyrolysis process. The volatile by-products of hemp carbonization were characterized by several methods (TGA, UV-VIS, TLC, Flash Prep-LC, UHPLC, ...
