Enzymatic upgrading of nanochitin using an ancient lytic polysaccharide monooxygenase
(Springer Nature, 2022-08-15)
Numerous enzymes have the potential to upgrade biomass, converting it into high-tech materials for new applications. However, the features of natural enzymes often limit their use beyond chemical conversion of the substrate. ...
Integrated Environmental and Exergoeconomic Analysis of Biomass-Derived Maleic Anhydride
(Wiley, 2022-09)
Life cycle analysis and exergy analysis are applied to compare the production of maleic anhydride from different feedstock, both biomass- and petrochemical-derived raw materials, in order to evaluate the sustainability of ...
Influence of Process Parameters in Graphene Oxide Obtention on the Properties of Mechanically Strong Alginate Nanocomposites
(MDPI, 2020-02-28)
Sodium alginate, a biopolymer extracted from brown algae, has shown great potential for many applications, mainly due to its remarkable biocompatibility and biodegradability. To broaden its fields of applications and improve ...
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, ...
Modelización fotoquímica optimizada aplicada a la compresión de los episodos de ozono troposférico en el Atlántico-Sur europeo
(2021-07-07)
Más del 98% de la población europea está expuesta a niveles nocivos de ozono troposférico según la OMS. En el Sur de Europa, la situación es todavía más grave debido a que, las mayores temperaturas y horas de luz solar que ...
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 ...
