Optimization of extraction of stinging nettle leaf phenolic compounds using response surface methodology
(Elsevier, Amsterdam, 2015)
A full three level factorial design was implemented for optimization of extraction parameters in order to maximize total phenolic (TP) yield from stinging nettle leaf. Factors considered were percentage of methanol in ...
Impregnation of cotton fabric with silver nanoparticles synthesized by dextran isolated from bacterial species Leuconostoc mesenteroides T3
(Elsevier Sci Ltd, Oxford, 2015)
This study was aimed to highlight the possibility of cotton fabric impregnation with silver nanoparticles synthesized by dextran isolated from Leuconostoc mesenteroides T3 in order to obtain antimicrobial properties. The ...
Micro-environmentally restricted cell growth dynamics - modeling considerations
(Taylor & Francis Ltd, Abingdon, 2015)
Various modeling approaches have been applied to describe the rearrangement of immobilized cell clusters within the extracellular matrix. The cell rearrangement has been related with the micro-environmental restrictions ...
Protein-reinforced and chitosan-pectin coated alginate microparticles for delivery of flavan-3-ol antioxidants and caffeine from green tea extract
(Elsevier Sci Ltd, Oxford, 2015)
In this study, potential interactions of alginate-proteins and proteins-polyphenols were utilized for the formulation of microparticles encapsulating green tea flavan-3-ols and caffeine. Electrostatic assisted extrusion ...
Novel and conventional working fluid mixtures for solar Rankine cycles: Performance assessment and multi-criteria selection
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
This work investigates the performance of working fluid mixtures for use in solar ORC (Organic Rankine Cycle systems) with heat storage employing FPC (Flat Plate Collectors). Several mixtures are considered including ...
Bond strength of restorative materials to hydroxyapatite inserts and dimensional changes of insert-containing restorations during polymerization
(Elsevier Sci Ltd, Oxford, 2015)
Objective. To determine the shear bond strength (SBS) between synthetic controlled porous hydroxyapatite (HAP) inserts and restorative materials and dimensional changes of insert-containing restorations during curing. ...
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 ...
Fully printed organic tandem solar cells using solution-processed silver nanowires and opaque silver as charge collecting electrodes
(Royal Soc Chemistry, Cambridge, 2015)
We report in this work efficient, fully printed tandem organic solar cells (OSCs) using solution-processed silver as the reflective bottom electrode and silver nanowires as the transparent top electrode. Employing two ...
Bioactive hydroxyapatite/graphene composite coating and its corrosion stability in simulated body fluid
(Elsevier Science Sa, Lausanne, 2015)
The hydroxyapatite/graphene (HAP/Gr) composite was electrodeposited on Ti using the electrophoretic deposition process to obtain uniform bioactive coating with improved mechanical strength and favorable corrosion stability ...
Preparation and characterization of novel P(HEA/IA) hydrogels for Cd2+ ion removal from aqueous solution
(Elsevier Science Bv, Amsterdam, 2015)
Series of novel hydrogels based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA), P(HEA/IA) copolymers, were prepared by free radical cross-linking copolymerization and investigated as potential adsorbents for Cd2+ ...
