GC-MS-based metabolomics for the detection of adulteration in oregano samples / Метаболомика заснована на гасној хроматографији–масеној спектрометрији за детекцију кривотворења узорака оригана.
(Serbian Chemical Society, 2021)
Oregano is one of the most used culinary herb and it is often adulterated with cheaper plants. In this study, GC–MS was used for identification and quantification of metabolites from 104 samples of oregano (Origanum ...
Synthesis, characterization and biological activity of Pt(II) complexes with steroidal thiosemicarbazones / Синтеза, карактеризација и биолошка активност комплекса Pt(II) са стероидним тиосемикарбазонима
(Belgrade : Serbian Chemical Society, 2021)
In this work, Pt(II) complexes of previously synthesized steroidal thiosemicarbazones were synthesized and characterized. The ligands and their metal complexes were studied by analytical and spectroscopic data (elemental ...
Synthesis of the new lost foam refractory coatings based on talc / Синтеза нових “lost foam” ватросталних премаза на бази талка
(Journal of the Serbian Chemical Society, 2022)
This paper is focused on the preparation procedures, using a talc-based filler, to improve the rheologic properties of the lost foam refractory coatings. Talc, with grain size of 40 .m, was mechanically activated in a ...
Application of LC-MS/MS with ion mobility for chemical analysis of propolis extracts with antimicrobial potential / Примена lc–ms/ms технике са јонском покретљивошћу за хемијску анализу екстраката прополиса са антимикробним потенцијалом.
(Serbian Chemical Society, 2021)
The objective of this study was to test four-dimensional LC-ESI-MS/MS chromatography in analysis of complex mixture such as ethanol extracts of different propolis samples. In total more than 1200 picks were identified and ...
