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 ...
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 ...
The study of thermal behavior of montmorillonite and hydromica brick clays in predicting tunnel kiln firing curve
(Elsevier Sci Ltd, Oxford, 2017)
The aim of this study was to test montmorillonite and hydromica type of brick clays by using simultaneous thermal analysis and dilatometry in an assessment of the suitability of brick clays to produce building elements. ...
Novel resveratrol delivery systems based on alginate-sucrose and alginate-chitosan microbeads containing liposomes
(Elsevier Sci Ltd, Oxford, 2016)
We reported the design of liposome-loaded Ca-alginate microspheres as a drug delivery system for controlled release of resveratrol. The effect of admixed sucrose and chitosan coating was assessed in terms of physicochemical, ...
Optimisation of microwave-assisted extraction parameters for antioxidants from waste Achillea millefolium dust
(Elsevier Science Bv, Amsterdam, 2015)
Microwave-assisted extraction of polyphenols and flavonoids from waste Achillea millefolium (yarrow) dust was optimised using the response surface methodology. The influence of the extraction time (13-47 s), ethanol ...
The impact of high-power ultrasound and microwave on the phenolic acid profile and antioxidant activity of the extract from yellow soybean seeds
(Elsevier Science Bv, Amsterdam, 2018)
The aim of the study was to investigate and compare several extraction protocols like 1) high-power ultrasound probe assisted solvent extraction; 2) microwave assisted solvent extraction; 3) direct acid hydrolysis; 4) ...
The kinetics of hydrogen absorption/desorption within nanostructured composite Ni79.1Co18.6Cu2.3 alloy using resistometry
(Elsevier Science Sa, Lausanne, 2013)
Ni79.1Co18.6Cu2.3 powder was obtained by electrochemical deposition from an ammonium sulfate bath. The structure and surface morphology of the powder were detected by X-ray diffraction (XRD) and scanning electron microscopy ...
A comprehensive approach to in vitro functional evaluation of Ag/alginate nanocomposite hydrogels
(Elsevier Sci Ltd, Oxford, 2014)
In this work, we present a comprehensive approach to evaluation of alginate microbeads with included silver nanoparticles (AgNPs) at the concentration range of 0.3-5 mM for potential biomedical use by combining cytotoxicity, ...
Molecular weight distribution and functional group profiles of TEMPO-oxidized lyocell fibers
(Elsevier Sci Ltd, Oxford, 2013)
The effects of TEMPO-mediated oxidation, performed with NaClO, a catalytic amount of NaBr, and 2,2',6,6'-tetramethylpiperidine-1-oxy radical (TEMPO), were studied on lyocell fibers by means of GPC using multiple detection ...
Composite materials from fully bio-based thermosetting resins and recycled waste poly(ethylene terephthalate)
(Elsevier Sci Ltd, Oxford, 2018)
During the last two decades, interest in bio-based polymers, especially in bio-based composite materials, has grown as a result of environmental concerns. In this paper new composites obtained from fully bio-based unsaturated ...
