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 ...
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 ...
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Neurological Entity?
(MDPI, 2021-09-27)
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a disorder of unknown physiopathology with multisystemic repercussions, framed in ICD-11 under the heading of neurology (8E49). There is no specific test to ...
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 ...
Vibrations Characterization in Milling of low Stiffness Parts with a Rubber-Based Vacuum Fixture
(Elsevier, 2021-06)
Fixtures are a critical element in machining operations as they are the interface between the part and the machine. These components are responsible for the precise part location on the machine table and for the proper ...
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 ...
