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 ...
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 ...
The effect of different extractants on lead desorption from a natural mineral
(Elsevier, Amsterdam, 2015)
Natural minerals, such as quartz, clinoptilolite and calcite, are useful as sorbents for various applications, but their content of heavy metals ions is the most problematic obstacle to their application. Before their ...
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 ...
Impact of sodium sulfate solution on mechanical properties and structure of fly ash based geopolymers
(Springer, Dordrecht, 2015)
In this paper, geopolymers based on two different fly ash samples were exposed to sodium sulfate (Na2SO4) solution (50 g/l) over a period of 365 days. It was found that sulfate solution attack caused a small decrease in ...
The antimicrobial efficiency of silver activated sorbents
(Elsevier Science Bv, Amsterdam, 2015)
This study is focused on the surface modifications of the materials that are used for antimicrobial water treatment. Sorbents of different origin were activated by Ag+-ions. The selection of the most appropriate materials ...
Trends in Encapsulation Technologies for Delivery of Food Bioactive Compounds
(Springer, New York, 2015)
The food industry expects increasingly complex properties (such as delayed release, stability, thermal protection, and suitable sensorial profile) from food ingredients, which often would not be able to be achieved without ...
Negative influence of Ag and TiO2 nanoparticles on biodegradation of cotton fabrics
(Springer, Dordrecht, 2015)
Recently, many efforts have been made to efficiently impregnate different textile materials with metal and metal oxide nanoparticles in order to provide antimicrobial, UV protective or self-cleaning properties. Evidence ...
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 ...
