Antibacterial and antifungal properties of guanylhydrazones
(Serbian Chemical Soc, Belgrade, 2017)
A series of novel guanylhydrazones were designed, synthesized and characterized. All the compounds were screened for their antibacterial and antifungal activity. Compounds 26 and 27 showed excellent antibacterial activities ...
STACKING INTERACTIONS BETWEEN PYRIDINE FRAGMENTS IN CRYSTAL STRUCTURES OF TERPYRIDYL COMPLEXES
(Univ Babes-Bolyai, Cluj-Napoca, 2010)
In the crystal structures of terpyridyl complexes from the Cambridge Structural Database (CSD) stacking interaction between the pyridine fragments were studied. Square-planar complexes where the distance between the centers ...
Determination of trace elements in refined gold samples by inductively coupled plasma atomic emission spectrometry / Određivanje tragova elemenata u uzorcima rafinisanog zlata atomskom emisionom spektrometrijom sa induktivno kuplovanom plazmom
(Serbian Chemical Soc, Belgrade, 2013)
This paper presents a method for the determination of trace contents of silver, copper, iron, palladium, zinc and platinum in refined gold samples. A simultaneous inductively coupled plasma atomic emission spectrometer in ...
Development of Inductively Coupled Plasma Atomic Emission Spectrometry for Arsenic Determination in Wine
(Hard, Olsztyn 5, 2011)
This paper describes a direct method for arsenic determination and speciation in wine samples by hydride atomic emission spectrometry with inductively coupled plasma (ICP-AES). Optimization of the method included investigation ...
Synthesis of endoperoxides by domino reactions of ketones and molecular oxygen
(Royal Soc Chemistry, Cambridge, 2015)
Domino reactions of ketones with molecular oxygen in the presence of potassium hydroxide and potassium t-butoxide afford cyclic hydroperoxy acetals (3,5-dihydroxy-1,2-dioxanes). Mixed endoperoxides can also be obtained in ...
Biotransformation of 4-halophenols to 4-halocatechols using Escherichia coli expressing 4-hydroxyphenylacetate 3-hydroxylase
(Springer, New York, 2011)
Escherichia coli cells, expressing 4-hydroxyphenylacetate 3-hydroxylase, fully transformed 4-halogenated phenols to their equivalent catechols as single products in shaken flasks. 4-Fluorophenol was transformed at a rate ...
Combined multivariate data analysis of high-performance thin-layer chromatography fingerprints and direct analysis in real time mass spectra for profiling of natural products like propolis
(Elsevier Science Bv, Amsterdam, 2014)
Sophisticated statistical tools are required to extract the full analytical power from high-performance thin-layer chromatography (HPTLC). Especially, the combination of HPTLC fingerprints (image) with chemometrics is ...
Pattern recognition methods and multivariate image analysis in HPTLC fingerprinting of propolis extracts
(Wiley-Blackwell, Hoboken, 2014)
High-performance thin-layer chromatography (HPTLC) combined with image analysis and pattern recognition methods were used for fingerprinting and classification of 52 propolis samples collected from Serbia and one sample ...
Leaching of toxic elements from secondary alkaline lead slag and stabilized/solidified products
(Springer Japan, 2019)
Secondary alkaline lead slag (SALS), generated during lead–acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization caused by storage under ...
Kinetics and mechanism of structural transformations of Fe 75Ni2Si8B13C2 amorphous alloy induced by thermal treatment
(Thermochimica Acta, 2011)
The kinetics of structural transformations of the Fe75Ni 2Si8B13C2 amorphous alloy under non-isothermal conditions was studied. It was shown that the amorphous alloy was stable up to 723 K, when multi-step structural ...
