Electrochemical Activity of Lignin Based Composite Membranes
(MDPI, 2021-02-21)
Our society’s most pressing challenges, like high CO2 emission and the constant battle against energy poverty, require a clean and easier solution to store and utilize the renewable energy resources. However, recent ...
Lignin-Based Polyols with Controlled Microstructure by Cationic Ring Opening Polymerization
(MDPI, 2021-02-22)
Lignin-based polyols (LBPs) with controlled microstructure were obtained by cationic ring opening polymerization (CROP) of oxiranes in an organosolv lignin (OL) tetrahydrofuran (THF) solution. The control on the microstructure ...
Advanced heterogeneous catalytic systems for biofuels production derived from HMF
(2021-02-22)
La presente tesis doctoral tiene como objetivo la obtención de biocombustibles a partir del 5-hidroximetilfurfural (HMF). Este compuesto es una molécula plataforma que se obtiene de la biomasa lignocelulósica. El HMF puede ...
Antioxidant, Antifungal and Phytochemical Investigations of Capparis spinosa L.
(MDPI, 2021-10-19)
The antioxidant and antifungal activities of crude hydro-ethanolic extract from Capparis spinosa L. (Capparidaceae) leaves and their fractions, obtained by liquid-liquid extraction (LLE) using solvents with increasing ...
Halochromic and antioxidant capacity of smart films of chitosan/chitin nanocrystals with curcuma oil and anthocyanins
(Elsevier, 2021-02)
Curcuma longa L. essential oil and anthocyanin extracts contain bioactive compounds such as antioxidant properties and their pigments are able to change color when exposed to different pH or ammonium gas. In this context, ...

Nanofibrillated Cellulose-Based Aerogels Functionalized with Tajuva (Maclura tinctoria) Heartwood Extract
(MDPI, 2021-03-16)
Aerogels are 3-D nanostructures of non-fluid colloidal interconnected porous networks consisting of loosely packed bonded particles that are expanded throughout their volume by gas and exhibit ultra-low density and high ...
Assessment of Bleached and Unbleached Nanofibers from Pistachio Shells for Nanopaper Making
(MDPI, 2021-03-04)
Cellulose and lignocellulose nanofibrils were extracted from pistachio shells utilizing environmentally friendly pulping and totally chlorine-free bleaching. The extracted nanofibers were used to elaborate nanopaper, a ...
New composite materials based on nanochitin and essential oils
(2021-06-22)
En los últimos años, el aislamiento de la quitina, que es el segundo polímero natural más abundante después de la celulosa, a partir de residuos de cáscaras de crustáceos ha generado un gran interés para su aplicación en ...
Molecular Weight Enables Fine-Tuning the Thermal and Dielectric Properties of Polymethacrylates Bearing Sulfonyl and Nitrile Groups as Dipolar Entities
(MDPI, 2021-01-20)
In this work, polymethacrylates containing sulfonyl and nitrile functional groups were successfully prepared by conventional radical polymerization and reversible addition-fragmentation chain-transfer polymerization (RAFT). ...
