A new polymorph of Ba(AsO3OH): Synthesis, crystal structure and vibrational spectra
Tamara Đorđević, Ljiljana Karanović (2010)A new monoclinic polymorph of Ba(AsO3OH) was synthesized under hydrothermal conditions. It represents a previously unknown structure type. Its crystal structure was determined from a racemic twin using single-crystal X-ray diffraction data collected at 120 and 293 K [space group P21, a=7.2149(14)/7.2370(2), b=7.7028(15)/7.7133(2), c=21.7385(43)/21.8079(5) Å, β=95.95(3)/96.073(1)1, V=1201.6(4)/1210.51(5) Å3, Z=12]. The crystal structure of P21-Ba(AsO3OH) has a layered character and is built up of four types of regularly alternating layers parallel to (0 0 1). Every AsO3OH tetrahedron is chelating to two Ba atoms and ...Ba(AsO3OH), хидротермална синтеза, структурна анализа монокристала, Раманска спектроскопија, инфрацрвена спектроскопија, водоничне везе, хидрогенарсенати земноалкалних металаTamara Đorđević, Ljiljana Karanović.

Preliminary impact assessment of No2 emission from a heating plant on air pollution: case of Zemun, Serbia
The aim of this paper is to provide a preliminary evaluation of the impact caused by NO2 emissions from a heating plant on the local air quality. To model the spatial distribution of NO2 emissions from the heating plant, the AERMOD model was employed. The evaluation was conducted by analyzing and contrasting the simulated NO2 concentration from the heating plant with the overall NO2 concentration recorded at the nearest monitoring station over the entire heating season. The study focused ...Boban Pavlović, Uroš Pantelić, Marija Živković, Dejan Ivezić.

The Flow Conditions in the Epikarst Zone of a Karst Aquifer. Case Study: Suva planina Mt., East Serbia
Branislav Petrović (2023)The epikarst as a part of the karst aquifer represents a complex point of contact and mixing of unconsolidated material from the terrain surface, carbonate rocks altered by “corrosive” water, flora and fauna (and remains of), which is partially saturated with groundwater. Significant amounts of (plant accessible) water, and other solutes and particles, can be stored in this zone for extended periods of time. Thus, attenuation or biochemical processes could start in this layer and change quality of infiltrated ...Branislav Petrović. "The Flow Conditions in the Epikarst Zone of a Karst Aquifer.

Unusually sluggish microemulsion system with water, toluene and a technical branched alkyl polyethoxylate
Marija Ilić, Franz-Hubert Haegel, Vesna Pavelkić, Snežana Zlatanović, Zoran Marković, Aleksandar Cvjetić (2015)Microemulsion systems with water, toluene and nonionic surfactants are interesting for application due to the excellent solvent properties of aromatic hydrocarbons. In this study, the pseudo-binary phase diagram (“fish-diagram”) of such a ternary system was investigated using a branched technical alkyl polyethoxylate. Lutensol ON 50 (i-C10E5) was considered a suitable surfactant. The system with technical branched i-C10E5 exhibits very long, and for compositions near optimum solubilization, i.e., the minimum content of surfactant needed for a bicontinuous microemulsion, extremely long ...микроемулзија, толуен, оксоалкохол етоксилат, термодинамичка стабилност, тернарни фазни дијаграми, дијаграми „fish“Marija Ilić, Franz-Hubert Haegel, Vesna Pavelkić, Snežana Zlatanović, Zoran Marković, Aleksandar Cvjetić.

Mechanical activation and silver supplementation as determinants of the antibacterial activity of titanium dioxide nanoparticles
Ljubica Anđelković, Marija Šuljagić, Vladimir Pavlović, Miljana Mirković, Boško Vrbica, Irena Novaković, Dalibor Stanković, Aleksandar Kremenović, Vuk Uskoković (2024)This study employed a novel synthetic approach involving a modified reverse co-precipitation method utilizing glacial acetic acid to synthesize α-Bi2O3 . X-ray powder diffraction and scanning and transmission electron microscopy analyses revealed the formation of a rod-like α-Bi2O3 microstructure. The prepared material was utilized to modify a glassy carbon paste (GCP) electrode for the development of an electrochemical sensor for acetaminophen (APAP) detection using differential pulse voltammetry (DPV). Cyclic voltammetry studies revealed that the GCP@Bi2O3 electrode exhibited enhanced electrochemical properties compared to the bare ...štapićasta a-Bi2O3 mikrostruktura, reverzna sinteza ko-precipitacije, elektrohemijski senzor, detekcija acetaminofenaLjubica Anđelković, Marija Šuljagić, Vladimir Pavlović, Miljana Mirković, Boško Vrbica, Irena Novaković, Dalibor Stanković, Aleksandar Kremenović, Vuk Uskoković.

Развој хибридног модела за оптиматизацију завршне контуре одлагалишта у површинској експлоатацији лежишта минералних сировина
Aлександар Додеровић (2024)Површинска експлоатација минералних сировина захтијева претходно откопавање значајних( милионских) количина јаловине, које је неопходно транспортовати до локације на којој ће сеона трајно одложити. Традиционални приступ избора локације и дизајна одлагалишта се карактерише парцијалним приступом, заснованом на анализи неколико водећих критеријума као и на личном искуству инжењера, често занемарујући синергетски ефекат осталих утицајних фактора Технолошке операције које се односе на манипулацију јаловином, међу којима предњачи транспорт, генеришу највећи дио трошкова у површинској експлоатацији.
