Electrooxidation of p-nitrophenol using a composite organo-smectite clay glassy carbon electrode
(Elsevier, 2014)
Bentonite clay rich in smectite clay mineral from seldom investigated locality Mecji Do (MD) in Serbia was modified. The organomodification was performed with different loadings of benzyltrimethylammonium (BTMA) cation. ...
Crystallographic and ab initio study of pyridine CH-O interactions: linearity of the interactions and influence of pyridine classical hydrogen bonds
(Royal Soc Chemistry, Cambridge, 2013)
The CH-O interactions of pyridine with water molecules were studied by analysing the data in the Cambridge Structural Database (CSD) and by ab initio calculations. The analysis of the CH-O interactions in the crystal ...
Effect of sepiolite organomodification on the performance of PCL/sepiolite nanocomposites
(Oxford : Pergamon-Elsevier Science Ltd, 2017)
Poly(epsilon-caprolactone) (PCL) based nanocomposites with unmodified and organomodified sepiolites were prepared by solution casting method. The sepiolites were modified with short (3-mercaptopropyl)trimethoxysilane ...
Structural modifications of 4-aryl-4-oxo-2-aminylbutanamides and their acetyl- and butyrylcholinesterase inhibitory activity. Investigation of AChE-ligand interactions by docking calculations and molecular dynamics simulations
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2014)
Congeneric set of thirty-eight 4-aryl-4-oxo-2-(N-aryl/cycloalkyl)butanamides has been designed, synthesized and evaluated for acetyl- and butyrylcholinesterase inhibitory activity. Structural variations included cycloalkylamino ...
Metabolomics study of Populus type propolis
(Elsevier, 2017)
Herein, we propose rapid and simple spectroscopic methods to determine the chemical composition of propolis derived from various Populus species using a metabolomics approach. In order to correlate variability in Populus ...
Apple pectin-derived oligosaccharides produce carbon dioxide radical anion in Fenton reaction and prevent growth of Escherichia coli and Staphylococcus aureus
(Elsevier, 2017)
Pectin is the main soluble fiber in apples or citruses. It may be fermented by gut microbiota to metabolites showing local intestinal and systemic effects. A wide range of beneficial effects of dietary pectin includes ...
Anaphoretical/oxidative approach to the in-situ synthesis of adherent hydroxyapatite/titanium oxide composite coatings on titanium
(Elsevier, 2019)
In-situ synthesis of HAp/TiO2 coating on titanium was performed via anaphoretic deposition of HAp and simultaneous anodization of Ti to produce highly adherent and strengthened composite coating. The prepared coatings were ...
Chemical composition, cytotoxic and antioxidative activities of ethanolic extracts of propolis on HCT-116 cell line
(Wiley, Hoboken, 2013)
BACKGROUND Propolis is a complex resinous sticky substance that honeybees collect from buds and exudates of various plants. Owing to its versatile biological and pharmacological activities, propolis is widely used in ...
Levels of toxic elements in canned fish from the Serbian markets and their health risks assessment
(Academic Press Inc Elsevier Science, San Diego, 2018)
A total of 138 samples of canned tuna, sardines and mackerel from the Serbian market were analyzed for toxic (As, Cd, Pb, Hg) element levels using ICPMS. The highest average contents of toxic elements were found to be 1.70 ...
in/out Isomerism of cyclophanes: a theoretical account of 2,6,15-trithia-[3(4,10)][7]metacyclophane and [3(4,10)][7]metacyclophane as well as their halogen substituted analogues
(Royal Soc Chemistry, Cambridge, 2017)
A detailed theoretical investigation of cyclophanes with a divergent set of methods ranging from molecular mechanics through semiempirical to ab initio is presented. Cyclophanes have attracted interest over the years due ...
