Antioxidant edible films based on chitosan and starch containing polyphenols from thyme extracts
(Elsevier Sci Ltd, Oxford, 2017)
The aim of this study was to analyse the antioxidant activity of different polymeric matrices based on chitosan and starch, incorporating a thyme extract (TE) rich in polyphenols. TE provided the films with remarkable ...
Antibacterial ability of immobilized silver nanoparticles in agar-agar films co-doped with magnesium ions
(Elsevier Sci Ltd, Oxford, 2019)
The antibacterial ability of in situ prepared nanometer-sized silver particles, immobilized in agar-agar films, was studied as a function of the concentration of co-dopant, magnesium ions. Content of inorganic components ...
Production of bioethanol from pre-treated cotton fabrics and waste cotton materials
(Elsevier Sci Ltd, Oxford, 2017)
This study highlights the potential of cotton fabric as a promising feedstock for the production of bioethanol as renewable biofuel. The effect of corona pre-treatment of non-mercerized and mercerized cotton fabrics on ...
Sodium periodate oxidized cotton yarn as carrier for immobilization of trypsin
(Elsevier Sci Ltd, Oxford, 2010)
Cotton yarn was first oxidized by sodium periodate to introduce aldehyde groups which were able to react with amino groups of trypsin to form Schiff's base, and result in cotton yarn immobilized trypsin. The effect of ...
Pectin-based nanocomposite aerogels for potential insulated food packaging application
(Elsevier Sci Ltd, Oxford, 2018)
Environmental-friendly pectin-TiO2 nanocomposite aerogels were prepared via sol-gel process and subsequent drying under supercritical conditions. The first step includes dissolution of pectin in water, addition of proper ...
Achieving high antimicrobial activity: Composite alginate hydrogel beads releasing activated charcoal with an immobilized active agent
(Elsevier Sci Ltd, Oxford, 2018)
New composites based on Ca-alginate hydrogels were produced that release activated charcoal (AC) particles with adsorbed povidone iodine (PVP-I) as a model antimicrobial substance in a physiological-like environment. ...
Antibacterial activity of Cu-based nanoparticles synthesized on the cotton fabrics modified with polycarboxylic acids
(Elsevier Sci Ltd, Oxford, 2018)
The fabrication of antimicrobial textile nanocomposite by in situ synthesis of Cu-based nanoparticles on cotton fabrics modified with different polycarboxylic acids was discussed in this study. In order to evaluate the ...
In situ chitosan gelation initiated by atmospheric plasma treatment
(Elsevier Ltd., 2014)
This work reports on the feasibility of atmospheric dielectric barrier discharge (DBD) plasma as a novel synthetic pathway for the liquid phase gelation of chitosan. The DBD plasma chitosan gelation process did not ...
Functionalization of polyester fabrics with alginates and TiO2 nanoparticles
(Elsevier Sci Ltd, Oxford, 2010)
This study was aimed to investigate the possibility of engineering the multifunctional textile nanocomposite material based on the polyester fabric modified with natural polysaccharide alginate and colloidal TiO2 nanoparticles. ...
Chitosan microbeads for encapsulation of thyme (Thymus serpyllum L.) polyphenols
(Elsevier Sci Ltd, Oxford, 2014)
In this work chitosan microbeads were prepared by emulsion technique and loaded with thyme polyphenols by diffusion from an external aqueous solution of Thymus serpyllum L. The effects of concentrations of chitosan (1.5-3% ...
