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). ...
Production and Properties of Lignin Nanoparticles from Ethanol Organosolv Liquors-Influence of Origin and Pretreatment Conditions
(MDPI, 2021-01-26)
Despite major efforts in recent years, lignin as an abundant biopolymer is still underutilized in material applications. The production of lignin nanoparticles with improved properties through a high specific surface area ...
Acid Hydrolysis of Almond Shells in a Biphasic Reaction System: Obtaining of Purified Hemicellulosic Monosaccharides in a Single Step
(Elsevier, 2021-05-21)
The aim of this work is to comprehend the biphasic reaction systems through another perspective; the simultaneous purification and production of carbohydrates during the pretreatment of biomass. A dilute acid hydrolysis ...
Influence of Heat Input on the Formation of Laves Phases and Hot Cracking in Plasma Arc Welding (PAW) Additive Manufacturing of Inconel 718
(MDPI, 2020-06-09)
Nickel-based alloys have had extensive immersion in the manufacturing world in recent decades, especially in high added value sectors such as the aeronautical sector. Inconel 718 is the most widespread in terms of implantation. ...
Termite Resistance of a Fast-Growing Pine Wood Treated by In Situ Polymerization of Three Different Precursors
(MDPI, 2020-08-08)
This study aims to compare the resistance against subterranean termites of wood–polymer composites produced by in situ polymerization. The biological tests were carried out by choice and no-choice feeding tests. Poly ...
