Magnetically responsive chitosan-pectin films incorporating Fe3O4 nanoparticles with enhanced antimicrobial activity.
(Elsevier, 2023-02)
Chitosan-pectin films with iron oxide (Fe3O4) magnetic nanoparticles were prepared by solution casting in order to produce biopolymer based magnetically active materials. Infrared (FTIR) spectra indicated physical interactions ...
Modelización y Optimización de SUDS Como Apoyo a la Toma de Decisiones
(2023-04-28)
La presente tesis tuvo el objetivo principal de plantear un esquema metodológico de modelización de los SUDS, a partir del cual se pudiera aportar de manera sistemática a la toma de decisiones en proyectos de drenaje urbano. ...
Combination of 3D printing and electrospinning to develop chitin/gelatin/PVA scaffolds
(ACC Science, 2023)
In this study, novel scaffolds based on natural polymers were developed by combining 3D printing (3DP) and electrospinning (ES) techniques. ES ink was prepared with gelatin and poly(vinyl alcohol) (PVA), while 3DP ink was ...
Development of nanostructured materials based on cellulose acetate modified with inorganic nanoparticles
(2023-03-01)
En el Capítulo 1 se presentó una revisión bibliográfica sobre la temática de esta tesis doctoral abarcando información sobre las matrices empleadas como son el acetato de celulosa y la madera, y se describió la capacidad ...
Study on the role of the reaction time in the upcycling of HDPE by co-hydrocracking it with VGO
(Elsevier, 2023-03)
Pursuing the aim of improving the current waste plastics management strategy, we have investigated the co-hydrocracking of high-density polyethylene (HDPE) with vacuum gasoil (VGO) over a PtPd/HY catalyst for converting ...
Integral Valorization of Grape Pomace for Antioxidant Pickering Emulsions
(MDPI, 2023-05-08)
Full harnessing of grape pomace (GP) agricultural waste for the preparation of antioxidant Pickering emulsions is presented herein. Bacterial cellulose (BC) and polyphenolic extract (GPPE) were both prepared from GP. ...
Main Routes of Production of High-Value-Added 2,5-Furandincarboxylic Acid Using Heterogeneous Catalytic Systems
(MDPI, 2023-05-13)
The production of polymers from lignocellulosic biomass is currently one of the challenges to minimizing dependence on fossil fuels such as oil. The cellulosic fraction of this feedstock can be transformed into simple ...
Syngas production by bio-oil steam gasification in a fountain confined conical spouted bed reactor
(Elsevier, 2023-08)
The combination of delocalized units for the fast pyrolysis of biomass to produce bio-oil followed by centralized units for the gasification of bio-oil appears as an economically attractive option for the full-scale ...
Microwave-assisted esterification of bleached and unbleached cellulose nanofibers
(Elsevier, 2023-01)
Microwave-assisted synthetic pathway was explored for the sustainable esterification of cellulose nanofibers (CNFs) using an aromatic amine compound. For this purpose, nanofibers were isolated from unbleached and bleached ...
Evaluation of Valorisation Strategies to Improve Grape Stems’ Nutritional Value as an Ingredient for Ruminants’ Diets
(MDPI, 2023-08-03)
Grape stems are a by-product of wine production which is managed as a waste. Animal feeding arises as a potential alternative. However, its practical use may be compromised by its high lignin content. In this sense, ...
