Cross-Linked Carboxymethylcellulose Adsorbtion Membranes from Ziziphus lotus for the Removal of Organic Dye Pollutants
(MDPI, 2022-12-08)
The goal of this study is to assess Ziziphus lotus’s potential for producing carboxymethylcellulose adsorption membranes with the ability to adsorb methyl green from wastewaters by the revalorization of its cellulosic ...
3D-Printed Mucoadhesive Collagen Scaffolds as a Local Tetrahydrocurcumin Delivery System
(MDPI, 2021-10-15)
Native collagen doughs were processed using a syringe-based extrusion 3D printer to obtain collagen scaffolds. Before processing, the rheological properties of the doughs were analyzed to determine the optimal 3D printing ...
Effect of the Addition of Alkaline Earth and Lanthanide Metals for the Modification of the Alumina Support in Ni and Ru Catalysts in CO2 Methanation
(MDPI, 2021-03-09)
In order to reduce greenhouse gas emissions, which are reaching alarming levels in the atmosphere, capture, recovery, and transformation of carbon dioxide emitted to methane is considered a potentially profitable process. ...
Effect of Fructose and Ascorbic Acid on the Performance of Cross-Linked Fish Gelatin Films
(MDPI, 2020-03-04)
Gelatin was extracted from fish scales in this work, in an attempt to valorise abundant and available fishery by-products as an approach towards a more circular economy. With this strategy in mind, fish scale gelatin was ...
Hydrogen Pressure as a Key Parameter to Control the Quality of the Naphtha Produced in the Hydrocracking of an HDPE/VGO Blend
(MDPI, 2022-05-16)
The hydrocracking of high-density polyethylene (HDPE) blended with vacuum gas oil (VGO) has been studied to assess the effect of H2 pressure on the yield and composition of the products and with the aim of obtaining ...
Pedagogical Approaches for Sustainable Development in Building in Higher Education
(MDPI, 2021-09-13)
Education for sustainable development (ESD) is one of the great challenges that university faculties have to face. Therefore, a multidisciplinary team from the faculty of Engineering of Gipuzkoa (EIG) at the University of ...
Environmental Assessment of University Campuses: The Case of the University of Navarra in Pamplona (Spain)
(MDPI, 2021-08-01)
Current European environmental sustainability standards call for achieving a reduction in energy consumption and CO2 emissions for a horizon set in the year 2050. It has been verified that buildings and cities have a higher ...
Use of Flat Interwoven Wooden Strips in Architecture and Construction. Simulation and Optimization Using 3D Digital Models
(MDPI, 2021-06-04)
This research aims to promote the use of natural materials in construction. Its purpose is to rediscover the interlacing of flat wooden strips. Attending to environmental criteria, it focuses on the study of wood from a ...
Effect of atomic substitution on the sodium manganese ferrite thermochemical cycle for hydrogen production
(Elsevier, 2022-10)
This work presents the effect of atomic substitution on the MnFe2O4-Na2CO3 thermochemical cycle for H-2 production. The non-oxidative decarbonation/carbonation reaction of the MnFe2O4-Na2CO3 mixture is investigated as the ...
Influence of Lewis acidity and CaCl2 on the direct transformation of glucose to 5-hydroxymethylfurfural
(Elsevier, 2021-06-11)
[EN] Nb-Zr oxides were evaluated for glucose dehydration to 5-hydroxymethylfurfural. A linear relationship was found between the amount of acid sites and niobium content. Pure Nb2O5 showed the highest acid concentration ...
