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 ...
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 ...
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 ...
Hydrophobization and Photo-Stabilization of Radiata Pinewood: The Effect of the Esterification on Thermal and Mechanical Properties
(MDPI, 2020-10-24)
Wood protection through chemical modification has received increasing interest over the last decades due to the environmental issues related to conventional biocides or protecting products. Consequently, a wide range of ...
Understanding the effects of copolymerized cellulose nanofibers and diatomite nanocomposite on blend chitosan films
(Elsevier, 2021-11-01)
Chitosan films lack various important physicochemical properties and need to be supplemented with reinforcing agents to bridge the gap. Herein, we have produced chitosan composite films supplemented with copolymerized (with ...
Nanocellulose-based sensing platforms for heavy metal ions detection: A comprehensive review.
(Pergamon-Elsevier, 2022-05-04)
Increase in industrial activities has been arising a severe concern about water pollution caused by heavy metal ions (HMIs), such us lead (Pb2+), cadmium (Cd2+) or mercury (Hg2+). The presence of substantial amounts of ...
Preparation of chitosan/tannin and montmorillonite films as adsorbents for Methyl Orange dye removal
(Elsevier, 2022-06-15)
A series of novel chitosan/tannin/montmorillonite (Cs/Tn/MMT) films were synthesised by loading different (from 0.2 to 0.5wt%) and MMT (from 0.5 to 1.5wt%) ratios, to be used as promising low-cost biosorbents for methyl ...
