Challenges and doubts of electrochemical energy conversion and storage / Izazovi i dileme elektrohemijske konverzije i skladištenja energije
(Beograd : Savez hemijskih inženjera Srbije / Belgrade : Association of the Chemical Engineers of Serbia, 2022)
Apstrakt Civilizacija se od kraja 20. veka suočava sa mnogim izazovima, od koji su neki od njih toliko ozbiljni da ugrožavaju i sam opstanak čovečanstva. Za neke se može reći da su novi, kao što je globalno zagrevanje, ali ...
Synthetic route towards 1,2,3,4-tetrahydroquinoxaline/piperidine combined tricyclic ring system / Синтетски пут за добијање 1,2,3,4-тетрахидрохиноксалинскo/пиперидинског трицикличног система
(Serbian Chemical Society, 2022)
The synthetic route toward novel tricyclic, nitrogen-containing system is disclosed. Three novel compounds possessing structural features of 1,2,3,4-tetrahydroquinoxaline and decahydropyrido[3,4-b]pyrazine are synthesized ...
Bioremediation of river sediment polluted with polychlorinated biphenyls: A laboratory study / Биодеградација полихлорованих бифенила у речном седименту: лабораторијска студија
(Belgrade : Serbian Chemical Society, 2022)
Persistent organic pollutants (POPs) are lipophilic, constant and bioaccumulative toxic compounds. In general, they are considered resistant to biological, photolytic, and chemical degradation with polychlorinated biphenyls ...
Investigations on the role of cation–pi interactions in active centres of superoxide dismutase / Испитивање улоге катјон–π интеракција у активним центрима супероксид-дисмутаза
(Serbian Chemical Society, 2022)
In this study, we have analysed the influence of cation–π interactions on stability and properties of superoxide dismutase (SOD) active centres. The number of interactions formed by arginine is higher than by lysine in the ...

Comparison of non-destructive techniques and conventionally used spectrometric techniques for determination of elements in plant samples (coniferous leaves) / Поређење недеструктивних и конвенционално коришћених спектометријских техника за одређивање елемената у биљном материјалу (иглице четинара)
(Journal of the Serbian Chemical Society, 2022)
Conventionally used spectrometric techniques of inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma optical emission spectrometry (ICP-MS) usually involve time-consuming sample ...
Forced Periodic Operation of Methanol Synthesis in an Isothermal Gradientless Reactor
(Wiley, 2022)
Methanol synthesis from synthesis gas with heterogeneous Cu/ZnO/Al2O3 catalysts in an isothermal gradientless reactor is described. In a theoretical study, the potential of forced periodic operation (FPO) for improving ...
Chemical profile of Nepeta cataria L. var. citriodora (Becker) essential oil and in vitro evaluation of biological activities
(Lublin : Uniwersytetu Przyrodniczego Lublin, 2022)
Essential oil (EO) obtained by hydrodistillation in a Clevenger-type apparatus from aerial parts of Nepeta cataria L. var. citriodora (Becker), cultivated in Serbia was subjected to gas chromatography-mass spectroscopy ...
Hardness and corrosion resistance of Zn−Mn/Al2O3 composite coatings produced by electrochemical deposition
(National Institute of Science Communication and Policy Research, 2022)
The aim of this study is development and characterization of the novel Zn-Mn/Al2O3 composite coatings. The coatings
were electrodeposited with constant current density on steel, from chloride solution, without any ...
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 ...
