Mesoporous Silica and Organosilica Nanomaterials as UV-Blocking Agents
(Amer Chemical Soc, Washington, 2018)
Mesoporous silica nanoparticles (MSN) and periodic mesoporous organosilica nanoparticles containing bridging benzene (PMOBTB) and ethane (PMOBTE) moieties are synthesized, characterized, and evaluated for application in ...
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. ...
Structural Elucidation of Enzymatically Synthesized Galacto-oligosaccharides Using Ion-Mobility Spectrometry Tandem Mass Spectrometry
(Amer Chemical Soc, Washington, 2016)
Galacto-oligosaccharides (GOS) represent a diverse group of well-characterized prebiotic ingredients derived from lactose in a reaction catalyzed with beta-galactosidases. Enzymatic transgalactosylation results in a mixture ...
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 ...
Lignin degradation by selected fungal species
(Elsevier Sci Ltd, Oxford, 2013)
As biological decomposition of plant biomass represents a popular alternative environmental-friendly and economically justified process, screening of ligninolytic enzyme systems of various fungal species is a topical study ...
Effect of Deposition Current Density and Annealing Temperature on the Microstructure, Hardness and Magnetic Properties of Nanostructured Nickel-Iron-Tungsten Alloys
(Electrochemical Soc Inc, Pennington, 2014)
Nanostructured nickel-iron-tungsten alloy coatings were electrodeposited from an ammonia citrate bath on steel and copper substrates at current densities in the range of 50 to 300 mA cm(-2). The contents of iron and tungsten ...
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, ...
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 ...
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 ...
