Electrochemical activity of iron in acid treated bentonite and influence of added nickel
(Elsevier, 2015)
Bentonite originated from Macji Do, Serbia, was submitted to acid treatment at 70 degrees C for 30 min, while only the concentration of applied HCl varied. The obtained acid treated samples were used to modify glassy carbon ...
Evaluation of antioxidant capacity of Allium ursinum L. volatile oil and its effect on membrane fluidity
(Elsevier Sci Ltd, Oxford, 2008)
A total of 20 components were identified in Allium ursinum volatile oil (AUVO) by GC-MS, and 10 of them are found for the first time in this plant species. The antioxidant capacity of AUVO was examined by beta-carotene-linoleic ...
Beneficial effect of Ni in pillared bentonite based electrodes on the electrochemical oxidation of phenol
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
The influence of Ni on the electrochemical performance of Fe containing bentonite-based electrode materials was investigated in the electrochemical oxidation of phenol in acidic solution. Clay originated from Mecji Do, ...
Autocatalator as the source of instability in the complex non-linear neuroendocrine model
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
The mathematical analogy between properties of simple and complex models of non-linear reactions was used to determine reaction steps in the complex model, necessary to generate instability region and appropriate type of ...
Antioxidant volatiles of the freshwater bryozoan Hyalinella punctata
(Taylor & Francis Ltd, Abingdon, 2014)
Two volatile samples of the bryozoan Hyalinella punctata (seasonally collected from the same locality) were isolated (hydrodistillation, Clevenger apparatus), identified (GC and GC-MS) and screened in vitro (EPR) for ...
Microhardness analysis of thin metallic multilayer composite films on copper substrates
(Technical Faculty, Bor, 2011)
Composite systems of alternately electrodeposited nanocrystalline Ni and Cu films on cold-rolled polycrystalline copper substrates were fabricated. Highly-densified parallel interfaces which can give rise to high strength ...
Heracleum orphanidis: chemical characterisation, and comparative evaluation of antioxidant and antimicrobial activities with specific interest in the influence on Pseudomonas aeruginosa PAO1
(Royal Soc Chemistry, Cambridge, 2016)
GC-FID and GC-MS were used to determine the chemical composition of the essential oil of the aerial parts of Heracleum orphanidis Boiss. Also, the HPLC-DAD/ESI-ToF-MS profile of the methanol extracts of aerial parts and ...
Absorption and fluorescence spectral properties of azo dyes based on 3-amido-6-hydroxy-4-methyl-2-pyridone: Solvent and substituent effects
(Elsevier, 2020)
A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-pyridones were synthesized and characterized by FT–IR, 1H and 13C NMR, UV–Vis, and PL spectroscopy. Photophysical properties of the dyes were examined ...
Diarylheptanoids from Green Alder Bark and Their Potential for DNA Protection
(Wiley-V C H Verlag Gmbh, Weinheim, 2014)
Nine diarylheptanoids, 1-9, catechin (11), and a phenolic glucoside, 10, were isolated from the bark of green alder (Alnus viridis). Four of the isolated compounds, i.e., 2, 5, 8, 10, are new. The structures of 1-11 were ...
Implementation of 5S tools as a starting point in business process reengineering / Primena 5S alata kao polazne osnove u reinženjeringu poslovnih procesa
(University of Novi Sad, Technical faculty Mihajlo Pupin, Zrenjanin, 2017)
The paper deals with the analysis of elements which represent a starting point in implementation of a business process reengineering. We have used Lean tools through the analysis of 5S model in our research. On the example ...
