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 ...
Synthesis, Characterization and Structure Properties of Biobased Hybrid Copolymers Consisting of Polydiene and Polypeptide Segments
(MDPI, 2021-11-04)
Novel hybrid materials of the PB-b-P(o-Bn-L-Tyr) and PI-b-P(o-Bn-L-Tyr) type (where PB: 1,4/1,2-poly(butadiene), PI: 3,4/1,2/1,4-poly(isoprene) and P(o-Bn-L-Tyr): poly(ortho-benzyl-L-tyrosine)) were synthesized through ...
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 ...
Particle emission measurements in three scenarios of mechanical degradation of polypropylene-nanoclay nanocomposites
(Elsevier, 2020-12)
Researchers and legislators have both claimed the necessity to standardize the exposure assessment of polymer nanocomposites throughout their life cycle. In the present study we have developed and compared three different ...
Molecular and Structure–Properties Comparison of an Anionically Synthesized Diblock Copolymer of the PS-b-PI Sequence and Its Hydrogenated or Sulfonated Derivatives
(MDPI, 2021-11-28)
An approach to obtaining various nanostructures utilizing a well-studied polystyrene-b-poly(isoprene) or PS-b-PI diblock copolymer system through chemical modification reactions is reported. The complete hydrogenation and ...
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 ...
