Evaluation of ZrO2/Al2O3 system as catalysts in the catalytic transfer hydrogenation of furfural to obtain furfuryl alcohol
(Elsevier, 2021-10-26)
ZrO2, Al2O3 and ZrO2/Al2O3 with different Zr/Al molar ratio, have been synthesized by coprecipitation and subsequent calcination. The resulting catalysts were characterized by X-ray diffraction, transmission electron ...
Enzymatically produced cellulose nanocrystals as reinforcement for waterborne polyurethane and its applications
(Elsevier Ltd., 2021-02)
[EN] Waterborne polyurethanes (WBPUs) have been proposed as ecofriendly elastomers with several applications in coatings and adhesives. WBPU’s physicochemical properties can be enhanced by the addition of cellulose ...

A feasibility study of the installation of a modular bioreactor inside a chemical scrubber at a wastewater treatment plant
(Elsevier, 2021-03)
Chemical scrubbing and biofiltration are well-established technologies for treating contaminated pollutants generated at wastewater treatment plants (WWTPs). Nevertheless, the growing need to reduce the ecological footprint ...
3D printed alginate-cellulose nanofibers based patches for local curcumin administration
(Elsevier, 2021-07)
Alginate and nanocellulose are potential biomaterials to be employed as bioinks for three-dimensional (3D) printing. Alginate-cellulose nanofibers (A-CNF) formulations with CNF amounts up to 5 wt% were developed and ...
The versatility of collagen and chitosan: From food to biomedical applications
(Elsevier, 2021-07)
Biodegradable polymers obtained from renewable resources, such as chitosan and collagen, are sustainable alternatives to develop environmentally friendly materials. Due to their abundance, biocompatibility and antimicrobial ...
Sustainable production of cellulose nanofiber from sugarcane trash: A quality and life cycle assessment
(Elsevier, 2021-09-29)
Developing green processes in the chemistry and engineering domains is one of the most significant challenges for sustainable production. Sugarcane trash (ST) generated during the sugar extraction process is an excellent ...
Modelización fotoquímica optimizada aplicada a la comprensión 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 ...
