Graphene-based antibacterial composite coatings electrodeposited on titanium for biomedical applications
(Elsevier Science Sa, Lausanne, 2015)
The graphene based silver/hydroxyapatite/graphene (Ag/HAP/Gr) composite coatings were produced by electrophoretic deposition (EPD) on titanium to assemble porous bioactive homogenous coatings, with improved corrosion ...
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 ...
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 ...
Two-stage fermentation for lactic acid production on distillery stillage / Dvostepena fermentacija za proizvodnju mlečne kiseline na destilerijskoj džibri
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2018)
The aim of this study was to assess utilization of distillery stillage in a two-stage fermentation using Bacillus licheniformis TFUNS and Lactobacillus paracasei NRRL B-4564. In the first stage the stillage was pretreated ...
Impregnation of cellulose acetate films with carvacrol using supercritical carbon ioxide / Impregnacija filmova acetata celuloze karvakrolom pomoću natkritičnog ugljenik(IV)-oksida
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Cellulose acetate films were impregnated with carvacrol using supercritical carbon dioxide. The supercritical impregnation process, conducted in a static regime at pressure of 21 MPa and temperature of 50°C, was optimized ...
Examination of the adhesion of polymer composite films based on Bis-GMA/TEGDMA on different metal substrates / Ispitivanje adhezije polimernih kompozitnih filmova na bazi Bis-GMA/TEGDMA na različitim metalnim podlogama
(Savez inženjera i tehničara Srbije, Beograd, 2018)
The subject of this study is the quantitative adhesion of a UV-curing composite film based on Bis-GMA (Bisphenol A glycidylmethacrylate) / TEGDMA (triethylene glycol dimethacrylate) as a matrix and particles doped with ...
Cefazolin-loaded polycaprolactone fibers produced via different electrospinning methods: Characterization, drug release and antibacterial effect
(Elsevier, Amsterdam, 2018)
Antibiotic containing polycaprolactone (PCL) fibers were produced by using three electrospinning methods: blend, emulsion and co-axial electrospinning (labeled as S1, S2 and S3, respectively). The profiles of drug release ...
Possibility of L-(+)-lactic acid fermentation using malting, brewing, and oil production by-products
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Industrial by-products such as brewer's spent grain (BSG) hydrolysate, malt rootlets extract (MRE) and soybean meal extract (SME) were used for L-(+) lactic acid (LA) production by a pure L rhamnosus ATCC 7469 strain. The ...
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 ...
