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 ...
Possible improvement of methanol synthesis exploiting forced periodic operation: Analysis using the Nonlinear Frequency Responce Method
(The Wilhelm und Else Heraeus-Stiftung, Germany, 2022)
Forced periodic operations, as one way of Process Intensification, can be used in order to achieve better performances of chemical reactors, in comparison to conventional steady-state operation. In this study the Nonlinear ...
Lignicolous mushroom Fomitopsis pinicola as a potent inhibitor of lipid peroxidation
(Novi sad: Matica Srpska, 2022)
Excessive production of reactive oxygen species (ROS) often results in irreversible cell damage and leads to a number of disorders such as hypertension, heart disease, diabetes, inflammation, premature aging and cancer. ...
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 ...
A new Nitzschia Hassall species (Bacillariaceae, Bacillariophyta) from saline ponds in Serbia
(Paris, France : Museum National d'Histoire Naturelle, 2022)
In the present study, a new species, Nitzschia haloserbica Vidaković, Ector, C.E.Wetzel & Krizmanić, sp. nov., is described from alkaline saline ponds and channels from Vojvodina Province (Serbia). In 2019 the new species ...
A comparative study of the molecular and isotopic composition of biomarkers in immature oil shale (Aleksinac deposit, Serbia) and its liquid pyrolysis products (open and closed systems)
(Elsevier, 2022)
The molecular and isotopic composition of biomarkers in initial bitumen isolated from immature (0.41% Rr) oil shale samples (Aleksinac deposit) and liquid products obtained by pyrolysis in open (OS) and closed (CS) systems ...
Study of thermal properties and microstructure of the Ag–Ge alloys
(Springer, 2022)
Microstructure, phase transitions and thermal properties including thermal diffusivity and thermal conductivity of four Ag–Ge alloys with 20, 40, 60 and 80 at % of Ge were experimentally investigated in this study. Observation ...
Superior elimination of Cr(VI) using polydopamine functionalized attapulgite supported nZVI composite: Behavior and mechanism
(Elsevier, 2022)
In this study, a polydopamine (PDA) modified attapulgite (ATP) supported nano sized zero-valent iron (nZVI) composite (PDA/ATP-nZVI) was rapidly synthesized under acidic conditions, and employed to alleviate Cr(VI) toxicity ...
Magnetic anisotropy in pentagonal bipyramidal complexes of first-row transition metal ions / Magnetna anizotropija u pentagonalno bipiramidalnim kompleksima prve serije prelaznih metala
(Belgrade : Serbian Chemical Society, 2022)
We present a validation study that aims to accurately describe magnetic anisotropy using the density functional theory (DFT) approach. We have examined 26 seven-coordinate high-spin first-row transition metal complexes ...
