Chitosan-Derived Iron Oxide Systems for Magnetically Guided and Efficient Water Purification Processes from Polycyclic Aromatic Hydrocarbons
(American Chemical Society, 2017-01)
Chitosan and pyrolyzed chitosan, acting as protective frameworks of magnetic nanoparticles (magnetite/maghemite and/or metallic Fe), have been investigated to be used in magnetically guided water remediation processes from ...
Sclerotium oryzae biocontrol in flooded rice fields with floating microcarrier technology: The effect of chitosan molecular weight
(John Wiley & Sons Ltd, 2021-07)
BACKGROUND: Biocontrol strategies are of significant concern for their application in crops. Various green practices have been designed, but almost all of them had delivery constraints. In particular, to design biocontrol ...
Single-step electrochemical deposition of antimicrobial orthopaedic coatings based on a bioactive glass/chitosan/nano-silver composite system
(Elsevier, 2013-07)
Composite orthopaedic coatings with antibacterial capability containing chitosan, Bioglass® particles (9.8ìm) and silver nanoparticles (Ag-np) were fabricated using a single-step electrophoretic deposition (EPD) technique, ...
Thermo-compression of biodegradable thermoplastic corn starch films containing chitin and chitosan
(Elsevier, 2014-06)
Films based on thermoplastic corn starch (TPS) and chitosan/chitin were obtained by melt-mixing and thermo-compression. Chitosan and chitin incorporation to TPS matrix induced some structural modifications due mainly to ...
Chitosan/iron oxide nanocomposite films: Effect of the composition and preparation methods on the adsorption of congo red
(Elsevier, 2019-10)
Composite films based on chitosan, glycerol and magnetic iron oxides were obtained by two different procedures: in situ generation of iron oxide particles in the already formed films and dispersion of previously synthesized ...
Enhanced properties of chitosan microparticles over bulk chitosan on the modulation of the auxin signaling pathway with beneficial impacts on root architecture in plants
(American Chemical Society, 2019-06-03)
Improving the root system architecture (RSA) under adverse environmental conditions by using biostimulants is emerging as a new trait to boost crop productivity. Recently, we have reported the characterization of novel ...
A microstructural study of acrylic-modified chitosan by means of PALS and SAXS
(Trans Tech Publications, 2017-03)
Chemical modification of chitosan, specially grafting with different polymers is an important strategy in the production of bio-based materials with enhanced properties. In the present study, chitosan was grafted with ...
Heat treatment to modify the structural and physical properties of chitosan-based films
(American Chemical Society, 2012-01)
This work was focused on studying the changes undergone by heat-treated chitosan films with and without tannic acid addition by monitoring both microstructure and physical properties. Once the films were submitted to ...
Crosslinking capacity of tannic acid in plasticized chitosan films
(Elsevier, 2010-09)
Plasticized and unplasticized chitosan films with tannic acid addition were developed. The crosslinking capacity of tannic acid was studied by evaluating both the structural modification produced on chitosan films and its ...
About endothermic sorption of tyrosine on chitosan films
(Elsevier, 2019-02-15)
Sorption of L- and D-Tyrosine (Tyr) from aqueous solutions on chiral membranes of chitosan (CH) was studied. A high adsorption in the membrane, with a marked enantioselectivity to L-Tyr, was found. Computational calculations ...
