Predicted Studies of Branched and Cross-Linked Polyurethanes Based on Polyhydroxybutyrate with Polycaprolactone Triol in Soft Segments
(MDPI, 2020-05-07)
The number of cross-links in the non-linear polyurethane structure is the basic factor affecting its properties. Selected properties of aliphatic polyurethanes with soft segments made of different amounts of polycaprolactonetriol, ...
Combustion of a Solid Recovered Fuel (SRF) Produced from the Polymeric Fraction of Automotive Shredder Residue (ASR)
(MDPI, 2021-11-03)
The use of alternative fuels derived from residues in energy-intensive industries that rely on fossil fuels can cause considerable energy cost savings, but also significant environmental benefits by conserving non-renewable ...
Secondary Raw Materials from Residual Carbon Fiber-Reinforced Composites by An Upgraded Pyrolysis Process
(MDPI, 2021-10-04)
This paper presents a process where carbon fibers and hydrogen can be recovered simultaneously through a two-stage thermal treatment of an epoxy-carbon fiber composite. For this purpose, some pieces of epoxy resin reinforced ...
Bio-Based Polyurethane Networks Derived from Liquefied Sawdust
(MDPI, 2021-06-07)
The utilization of forestry waste resources in the production of polyurethane resins is a promising green alternative to the use of unsustainable resources. Liquefaction of wood-based biomass gives polyols with properties ...
The Effect of Cross-Linking with Citric Acid on the Properties of Agar/Fish Gelatin Films
(MDPI, 2020-02-02)
The aim of this work was to assess the effect of fish gelatin–citric acid nucleophilic substitution and agar–citric acid esterification reactions on the properties of agar/fish gelatin films. Since temperature ...
Superabsorbent bacterial cellulose spheres biosynthesized from winery by-products as natural carriers for fertilizers
(Elsevier, 2021-11-30)
[EN]Soil contamination, sustainable management of water resources and controlled release of agrochemicals are the main challenges of modern agriculture. In this work, the synthesis of sphere-like bacterial cellulose (BC) ...
Hybrid 3D Printed and Electrospun Multi-Scale Hierarchical Polycaprolactone Scaffolds to Induce Bone Differentiation
(MDPI, 2022-12-19)
Complex scaffolds composed of micro- and nano-structures are a key target in tissue engineering and the combination of sequential 3D printing and electrospinning enables the fabrication of these multi-scale structures. In ...
Using Competency Maps for Embedding and Assessing Sustainability in Engineering Degrees
(MDPI, 2022-12-19)
This paper features a methodology for embedding and assessing a competency in an academic curriculum using competency maps. This methodology enables embedding and assessment of any competency in any curriculum, regardless ...
Wood Flour Modified by Poly(furfuryl alcohol) as a Filler in Rigid Polyurethane Foams: Effect on Water Uptake
(MDPI, 2022-12-16)
The use of lignocellulosic fillers in rigid polyurethane foams (RPUFs) has been receiving great attention due to their good mechanical and insulation properties and the high sustainable appeal of the obtained cellular ...
Dataset on the environmental and social footprint of the University of the Basque Country UPV/EHU
(Elsevier, 2022-04)
[EN] The organisational life cycle assessment (O-LCA) and the social organisational life cycle assessment (SO-LCA) of the University of the Basque Country UPV/EHU were conducted. The data presented in this paper support ...
