Silver/poly(vinyl alcohol)/chitosan/graphene hydrogels - Synthesis, biological and physicochemical properties and silver release kinetics
(Elsevier Sci Ltd, Oxford, 2018)
This study presents the synthesis of novel silver/poly(vinyl alcohol)/chitosan/graphene (Ag/PVA/CHI/Gr) nanocomposite hydrogels by in situ electrochemical reduction of silver ions in the hydrogel matrix and their thorough ...
Leaves of common urban tree species (Aesculus hippocastanum, Acer platanoides, Betula pendula and Tilia cordata) as a measure of particle and particle-bound pollution: a 4-year study
(Springer, Dordrecht, 2019)
Magnetic biomonitoring using tree leaves has been proven as a proxy for airborne particle matter (PM) pollution. Since the leaf entrapment of PM is species-specific, in this study, four tree species common in urban areas ...
The innovative combined microwave-assisted and photo-polymerization technique for synthesis of the novel degradable hydroxyethyl (meth)acrylate/gelatin based scaffolds
(Elsevier Science Bv, Amsterdam, 2018)
The discovery of novel biodegradable biomaterials able to support and control cellular activity as well as development of an enhanced and efficient method for their fabrication, are of paramount importance in the field of ...
Development of material with strong antimicrobial activity by high pressure CO2 impregnation of polyamide nanofibers with thymol
(Elsevier Sci Ltd, Oxford, 2018)
This study discusses the potential of high pressure (supercritical and liquid) CO2 impregnation to load electrospun polyamide nanofibers with thymol as an antimicrobial agent. The influence of selected pressures and ...
Effect of inorganic ions, photosensitisers and scavengers on the photocatalytic degradation of nicosulfuron
(Elsevier Science Sa, Lausanne, 2017)
In the present study, the photocatalytic degradation of nicosulfuron, using TiO2 as a catalyst under UV light (315-400 nm), was studied. The optimization of the nicosulfuron photodegradation was performed. It was found ...
Physical-chemical behavior of novel copolymers composed of methacrylic acid and 2-acrylamido-2-methylpropane sulfonic acid
(Elsevier Science Sa, Lausanne, 2016)
This article described the synthesis and characterization of new copolymer hydrogels containing two hydrophilic units-methacrylic acid (MAA) and 2-Acrylamido-2-methylpropane sulfonic acid (AMPS). The resulting hydrogels ...
Comparative study of CeO2 nanopowders obtained by the hydrothermal method from various precursors
(Elsevier Sci Ltd, Oxford, 2015)
The effects of common precursors used in the synthesis of CeO2 nanopowders were investigated, and the structural and spectral properties of the resulting products were compared. Two cerium (III) salts, i.e., Ce(NO3)(3)center ...
The synergistic effect of heat treatment on alcalase-assisted hydrolysis of wheat gluten proteins: Functional and antioxidant properties
(Wiley, Hoboken, 2017)
In order to confirm the gluten potential for inclusion into functional foods, the synergistic effect of the heat treatment and controlled enzymatic hydrolysis on the functional and the antioxidant properties of alcalase-assisted ...
Lactic acid production on molasses enriched potato stillage by Lactobacillus paracasei immobilized onto agro-industrial waste supports
(Elsevier Science Bv, Amsterdam, 2018)
In this study, the production of lactic acid (LA) on sugar beet molasses enriched potato stillage by immobilized Lactobacillus paracasei NRRL B-4564 was examined. Three agro-industrial materials, such as sunflower seed ...
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. ...
