Kinetic models of swelling and thermal stability of silver/poly(vinyl Check far alcohol)/chitosan/graphene hydrogels
(Elsevier Science Inc, New York, 2019)
Silver nanoparticles (AgNPs) were synthesized by in situ electrochemical reduction of Ag+ ions in poly (vinyl alcohol)/chitosan/graphene (PVA/CHI/Gr) hydrogel matrices with different concentrations of chitosan. The ...
Supercritical CO2 - assisted production of PLA and PLGA foams for controlled thymol release
(Elsevier Science Bv, Amsterdam, 2019)
Amorphous, medical grade poly(D,L-lactic acid) (PLA) and poly(D,L-lactic-co-glycolic acid) (PLGA) were used to develop systems for controlled release of a natural bioactive substance - thymol. Supercritical carbon dioxide ...
Chitosan-based hydrogel wound dressings with electrochemically incorporated silver nanoparticles - In vitro study
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this work, we provide a facile path for the preparation of wound dressing materials with improved characteristics based on biocompatible chitosan and poly(vinyl alcohol) hydrogels with embedded silver nanoparticles ...
Effects of caraway and juniper essential oils on aflatoxigenic fungi growth and aflatoxins secretion in polenta
(Wiley, Hoboken, 2019)
Inhibitory activity of caraway and juniper essential oils was tested against two aflatoxigenic strains (Aspergillus flavus-four isolates and Aspergillus parasiticus-one isolate) using the method of agar plates. A. flavus ...
Synthesis and characterization of nanocrystalline polyhedral oligo silsesquioxanes (POSS) with cross-linkable functionalities
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
A facile synthesis was employed for three polyhedral oligo silsequioxanes (POSS), obtaining incompletely condensed structures with fern-like and cubic morphologies. Proton nuclear magnetic resonance spectroscopy (H-1 NMR) ...
Nano-finishing of cellulose textile materials with copper and copper oxide nanoparticles
(Springer, Dordrecht, 2019)
Nano-finishing of textile materials with metal and metal oxide nanoparticles has been in the focus of science and textile industry almost two decades. The emergence of bacteria resistance to silver nanoparticles due to ...
Effect of surface activation of alumina particles on the performances of thermosetting-based composite materials
(Sage Publications Ltd, London, 2019)
Two types of alumina particles, commercial (c-Al2O3) and iron doped (Fe-Al2O3), were functionalized with 3-(aminopropyl)trimethoxysilane (one-step) and two-step consecutive process, i.e. firstly using 3-(aminopropyl)trim ...
Broad Spectrum of Antimicrobial Activity of Cotton Fabric Modified with Oxalic Acid and CuO/Cu2O Nanoparticles
(Korean Fiber Soc, Seoul, 2019)
This study discusses the possibility of fabrication of textile nanocomposites with antimicrobial activity against antibiotics-resistant bacterial strains and yeast. Modification of cotton fabric with oxalic acid solutions ...
Doping of TiO2 nanotubes with nitrogen by annealing in ammonia for visible light activation: Influence of pre- and post-annealing in air
(Elsevier Science Sa, Lausanne, 2019)
The similar to 60 nm wide and similar to 2 mu m long TiO2 nanotubes were obtained by anodization of Ti films sputtered on F-doped tin oxide glass. For N-doping the samples were annealed in ammonia atmosphere. The effect ...
The influence of alumina particle modification on the adhesion of the polyacrylate matrix composite films and the metal substrate
(Taylor & Francis Ltd, Abingdon, 2019)
Adhesion behavior between the composite films, consisting of UV cured Bis-GMA (Bisphenol A glycidylmethacrylate)/TEGDMA (triethylene glycol dimethacrylate) as a matrix and the ferrous oxide doped alumina particles, Al2O3 ...
