Optimization of extraction of stinging nettle leaf phenolic compounds using response surface methodology
(Elsevier, 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 ...
Sorption of zinc by novel pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid
(Elsevier, 2011)
Novel pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid were applied as adsorbents for the removal of Zn(2+) ions from aqueous solution. In batch tests, the influence of solution pH, contact time, ...
RuxTi1-xO2 as the support for Pt nanoparticles: Electrocatalysis of methanol oxidation
(Elsevier, 2015)
Two binary Ru-Ti oxides, Rum Ti0.9O2 and Ru0.7Ti0.3O2, were synthesized by the sol-gel method and used as an electrocatalyst support. The system was characterized by XRD, EDS, TEM and cyclic voltammetry. The Rum Ti0.9O2 ...
Chemical Composition of Two Different Extracts of Berries Harvested in Serbia
(American Chemical Society (ACS), 2013)
Total phenolic content (TPC), total anthocyanin content (TAC), free and total ellagic acid content, sugars, minerals, and radical scavenging activity were determined in nine berries harvested in Serbia. More than 30 phenolic ...
The HPA axis and ethanol: a synthesis of mathematical modelling and experimental observations
(Wiley, Hoboken, 2017)
Stress and alcohol use are interrelatedstress contributes to the initiation and upholding of alcohol use and alcohol use alters the way we perceive and respond to stress. Intricate mechanisms through which ethanol alters ...
Application of a Novel Antioxidative Assay in Beer Analysis and Brewing Process Monitoring
(American Chemical Society (ACS), 2010)
A novel antioxidative assay based on direct current polarography has been developed. Quantification of antioxidative (AO) activity has been based on a decrease of hydrogen peroxide anodic current in the presence of ...
Decrease of free fatty acid content in vegetable oil using silica supported ferric sulfate catalyst
(Elsevier Sci Ltd, Oxford, 2012)
A difficulty of biodiesel synthesis based on alkaline catalysts obviously exists if free fatty acids (FFAs) content in vegetable oil is above 0.5 wt.%. In this study, the ferric sulfate supported on silica (Fe-2(SO4)(3)/SiO2) ...
Immobilization of biocatalysts for enzymatic polymerizations: Possibilities, advantages, applications
(Elsevier Sci Ltd, Oxford, 2012)
Biotechnology also holds tremendous opportunities for realizing functional polymeric materials. Biocatalytic pathways to polymeric materials are an emerging research area with not only enormous scientific and technological ...
Coordinating Benzenes Stack Stronger than Noncoordinating Benzenes, even at Large Horizontal Displacements
(American Chemical Society (ACS), 2016)
Stacking interactions between two benzene molecules that coordinate transition metal ions within organometallic sandwich and half-sandwich compounds were investigated by performing Cambridge Structural Database (CSD) search ...
