Desarrollo de materiales poliméricos híbridos (caucho EPDM-SMC) sin uso de adhesivos.
(2021-03-03)
El objetivo de esta tesis es mejorar la adherencia entre el SMC (Sheet Moulding Compound) y el caucho EPDM (Etileno Propileno Dieno tipo M), sin necesidad de adicionar productos intermedios, como primers o adhesivos, antes ...
Multiple Intelligence Informed Resources for Addressing Sustainable Development Goals in Management Engineering
(MDPI, 2022)
The competence-based model focuses on acquiring skills and abilities, yet each student’s individual circumstances condition the way in which they learn, develop, and implement them. Accordingly, there is a growing interest ...
One-Step Lignin Refining Process: The Influence of the Solvent Nature on the Properties and Quality of Fractions
(MDPI, 2022)
Heterogeneity of kraft lignin is one of the main limitations for the development of high-performance applications. Therefore, refining lignin using organic solvents is a promising strategy to obtain homogenous fractions ...
Chitosan Films Incorporated with Exopolysaccharides from Deep Seawater Alteromonas sp.
(MDPI, 2020-08-27)
Two Alteromonas sp. strains isolated from deep seawater were grown to promote the production of exopolysaccharides (EPS, E611 and E805), which were incorporated into chitosan solutions to develop films. The combination of ...
Insights into the Nature of the Active Sites of Pt-WOx/Al2O3 Catalysts for Glycerol Hydrogenolysis into 1,3-Propanediol
(MDPI, 2021-09-27)
The chemo-selective hydrogenolysis of secondary hydroxyls is an important reaction for the production of biomass-derived α,ω-diols. This is the case for 1,3-propanediol production from glycerol. Supported Pt-WOx materials ...

(2020-12-09)
A series of waterborne polyurethane urea dispersions were prepared to study their viability as inks for direct ink writing 3D-printing. In this context, waterborne polyurethane urea dispersions were successfully synthesized ...
Design of a Waterborne Polyurethane-Urea Ink for Direct Ink Writing 3D Printing
(MDPI, 2021-06-14)
In this work, polycaprolactone–polyethylene glycol (PCL–PEG) based waterborne polyurethane–urea (WBPUU) inks have been developed for an extrusion-based 3D printing technology. The WBPUU, synthesized from an optimized ratio ...
Design and Characterization of Waterborne Polyurethane-Urea based Nanocomposites for 3D Printing
(2021-12-09)
Polyurethane-ureas are very versatile polymers that can be process in many ways and used in an extremely wide field of applications. At the same time, 3D printing offers the opportunity to make one on one personalized ...
Polyurethane films prepared with isophorone diisocyanate functionalized wheat starch
(Elsevier, 2021-12-05)
[EN]This study reports the fabrication and performance of sustainable polyurethane (PU) films based on wheat starch (native NS, modified MS), bio-polyols (1,3-propanediol PD, glycerol Gly), and polymeric diphenylmethane ...
Optimization of Ultrasound Assisted Extraction of Bioactive Compounds from Apple Pomace
(MDPI, 2021-06-22)
In the present work, the optimization of the extraction of antioxidant compounds from apple pomace using ultrasound technology as an environmentally friendly and intensification process was developed. Different sonication ...
