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 ...
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 ...
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 ...
A Holistic Approach to Integrate and Evaluate Sustainable Development in Higher Education. The Case Study of the University of the Basque Country
(MDPI, 2021-01-04)
Since the United Nations (UN) approved the Agenda 2030 for Sustainable Development in 2015, higher education institutions have increasingly demonstrated their commitment by supporting several initiatives. Although a great ...
Metal Extraction and Recovery from Mobile Phone PCBs by a Combination of Bioleaching and Precipitation Processes
(MDPI, 2021-09-15)
Bearing in mind the metal rich composition of printed circuit boards (PCBs), this material represents a secondary source of valuable metals and offers an entrepreneurial opportunity in the metal sales market. Based on the ...
Kinetic modelling for concentration and toxicity changes during the oxidation of 4-chlorophenol by UV/H2O2
(Nature, 2021-08-03)
This work develops a kinetic model that allow to predict the water toxicity and the main degradation products concentration of aqueous solutions containing 4-chlorophenol oxidised by UV/H2O2. The kinetic model was developed ...
Fe/Olivine As Primary Catalyst in the Biomass Steam Gasification in a Fountain Confined Spouted Bed Reactor
(Elsevier, 2021-07-25)
The performance of Fe/olivine catalysts was tested in the continuous steam gasification of sawdust in a bench scale plant provided with a fountain confined conical spouted bed reactor at 850 degrees C. Olivine was used as ...
