Sinteza i karakterizacija vanadata alkalnih metala sa elementima retkih zemalja
Anđela Jovanović (2024)Predmet i cilj pisanja ovog rada su sinteza i karakterizacija vanadata alkalnih metala sa elementima retkih zemalja. Prilikom ovih istraživanja, ispitivan je sistem REE2O3–V2O5–KF, gde REE predstavlja trovalentni katjon izabranih elemenata retkih zemalja (Y, Sm, Eu, Gd, Er, Yb). Ovo istraživanje bazirano je na sintezi kristala, nakon čega su dobijeni kristali posmatrani pod binokularnom lupom, analizirani metodom rendgenske difrakcije na polikristalnom materijalu (XRPD) i metodom skenirajuće elektronske mikroskopije sa energetsko-disperzivnom spektroskopijom (SEM-EDS), kako bi se utvrdile karakteristike dobijenih kristala. ...elementi retkih zemalja, sinteza kristala metodom fluksa, vanadati alkalnih metala, rendgenska difrakcija, SEM-EDS metodaAnđela Jovanović.

Crystallographic, spectroscopic, thermal and computational studies of polymeric cobalt(II)–mellitate complex with 2,2′-bipyridine
Orange single crystals of new polymeric cobalt(II) complex {[Co(bipy)(H2O)4]2[Co(μ-mell)(H2O)2]·10H2O}n, 1, were synthesized by slow evaporation method at room temperature (bipy = 2,2′-bipyridine, mell = hexaanion of mellitic acid) and its crystal structure was determined by single-crystal X-ray diffraction. The complex 1 was characterized based on elemental analysis, FTIR spectroscopy and thermal (TG/DTA) analysis followed by computational analysis of noncovalent interactions and quantum chemical calculations of interaction energies. In 1, two crystallographically different Co(II) atoms adopt a deformed octahedral geometry, ...Lidija Radovanović, Dušan P. Malenov, Marko V. Rodić, Aleksandar Kremenović, Jelena Rogan.

Punctuated, episodic magmatism and mineralization of the Rogozna skarn-hosted Au-Zn-Pb-Cu deposits revealed through high-precision U-Pb zircon geochronology
The subvolcanic regions of magmatic centers are commonly associated with alteration, mineralization, and economic ore deposits, however the duration and frequency of mineralizing pulses within the overall lifespan of these centers can be poorly defined. Therefore, models for the formation of mineral systems require more highprecision geochronology data to refine their evolutionary models. Rogozna Mountain and its eponymous magmatic complex, located in SW Serbia, hosts multiple base metal deposits associated with variable rock types and structural expressions and serves as a natural laboratory to ...Skarnovska mineralizacija, Magmatsko-hidrothermalni sistemi, Subvulcanske intruzije, geohronologija na cirkonima, CA-ID-TIMSSean P.

Hydrochemistry of groundwater contaminated by petroleum hydrocarbons: the impact of biodegradation (Vitanovac, Serbia)
Nenad Marić, Jana Štrbački, Sanja Mrazovac Kurilić, Vladimir P. Beškoski, Zoran Nikić, Snežana Ignjatović, Jovana Malbašić (2020)Aquifer contamination by petroleum hydrocarbons leads to measurable changes of groundwater hydrochemistry, primarily due to the microbiological activity. This study analyzes this phenomenon at an historical kerosene-contaminated site in Vitanovac (central Serbia). Due to the long-term hydrocarbon contamination and exposure to aerobic and anaerobic biodegradation mechanisms, the lowest concentrations of O2, NO3−, and SO42− (electron acceptors) and the highest concentrations of Mn and Fe (products of microbial metabolic activity) overlap. The terminal redox-accepting processes in groundwater ranged from oxygen ...Nenad Marić, Jana Štrbački, Sanja Mrazovac Kurilić, Vladimir P. Beškoski, Zoran Nikić, Snežana Ignjatović, Jovana Malbašić.

Kostić (2019)The goal of this study is to evaluate the quality of seven natural mineral water sources in the Vrnjačka Banja area used in the treatment of various diseases. The 24 macro- and microelements were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The results show that element content was within allowed limits of concentration, except for B, As, and Se. The evaluated content of these elements can be associated with geological and anthropogenic factors. The sample S6 contains ...Nebojša Đ. Pantelić, Simona Jaćimović, Jana Štrbački, Danijela B.

A Multilingual Evaluation Dataset for Monolingual Word Sense Alignment
Sina Ahmadi, John P McCrae, Sanni Nimb, Fahad Khan, Monica Monachini, Bolette S Pedersen, Thierry Declerck, Tanja Wissik, Andrea Bellandi, Irene Pisani, [...] Ranka Stanković and others (2020)Aligning senses across resources and languages is a challenging task with beneficial applications in the field of natural language processing and electronic lexicography. In this paper, we describe our efforts in manually aligning monolingual dictionaries. The alignment is carried out at sense-level for various resources in 15 languages. Moreover, senses are annotated with possible semantic relationships such as broadness, narrowness, relatedness, and equivalence.
