  • NMR kinetic studies of the interactions between [Ru(terpy)(bipy)(H2O)]2+ and some sulfur-donor ligands

    Aleksandar Mijatović, Biljana Šmit, Ana Rilak, Biljana Petrović, Dragan Čanović, Živadin D. Bugarčić (2012)
    Reakcije supstitucije monofunkcionalnog [Ru(terpi)(bipi)(H2O)]2+ kompleksa, gde je terpi = 2,2′:6′,2″-terpiridin i bipi = 2,2′-bipiridin, sa biološki relevantnim sumporo donorskim ligandima, kao što su tiourea, l-metionin, l-cistein i glutation, proučavane su u vodenim rastvorima tehnikom 1H i 13C NMR spektroskopije. Sve reakcije su proučavajne na pH 7,4, u prisustvu fosfatnog pufera, da bi se oponašalo fiziološko okruženje tokom procesa supstitucije. Reakcije se izvode na 295 K pod uslovima reakcija drugog reda. Uočeni rezultati pokazuju da brzina supstitucije snažno zavisi ...

  • Synergy between the mineral deposit exploration and geothermal resources assessment on the example of "Valjevo" boron and lithium deposit in Serbia

    Nebojša Atanacković, Vladimir Živanović, Ana Vranješ, Sava Magazinović, Marinko Toljić, Ana Arifović, Branislav Potić (2023)
    Exploration of mineral deposits involves a collection of vast data sets on geological characteristics of the area. These data can largely contribute to the assessment of the geothermal potential, which can lead to an increase in the share of geothermal resources in the energy mix of the extractive industry and the local community. On the example of the "Valjevo" B-Li deposit, data on structural settings and previous hydrogeological investigations were combined with the results of resource drilling and geophysical ...

  • Digitalizacija u rudarstvu: Kreiranje sistema za efikasno poslovno izveštavanje

    Stevan Đenadić, Aleksandar Mirković, Veljko Rupar (2024)
    Proces donošenja odluka u oblasti rudarstva i geologije uslovljen je blagovremenim posedovanjem kvalitetnih podataka i informacija. Kompleksnost rudarskih procesa nalaže prikupljanje podataka na dnevnom odnosno na smenskom nivou. Podaci kao takvi bez analitičkog pristupa nisu dovoljni. Kako bi pristup podacima bio brz i efikasan neophodno je posedovanje adekvatnog digitalnog rešenja uz adekvatne centralizovane baze podataka. U ovom radu je dat pregled trenutne pozicije rudarstva sa aspekta digitalne transformacije kao i predlog jednostavnog prototipa u obliku digitalnog sistema za poslovno ...

  • Natural two-dimensional pyrophyllite: Nanoscale lubricant, electrical insulator and easily-machinable material

    Borislav Vasić, Radoš Gajić, Ivana Milošević, Žarko Medić, Marina Blagojev, Marko Opačić, Aleksandar Kremenović, Dejan Lazić (2022)
    Pyrophyllite, with the chemical formula Al2Si4O10(OH)2, is a naturally occurring and abundant van der Waals mineral belonging to the group of phyllosilicates. It is very soft, layered crystal used for sculpting and an excellent electrical and thermal insulator aimed for the operation at high pressure and temperature. Here, for the first time, two-dimensional (2D) pyrophyllite obtained by both mechanical and liquid phase exfoliation is presented and investigated at the nanoscale. The layered structure provides low friction coefficient of around ...

  • High-resolution sequence stratigraphy of carbonates - theory and examples

    Jelena Stefanović, Dejan Radivojević (2020)
    Циљ рада је да кроз теоријски аспект и примере примене представи секвенциону стратиграфију високе резолуције карбонатних седимената. У том смислу први део се односи на појам и значење високе резолуције у секвенционој стратиграфији. Од временских и просторних скала које одговарају сеизмичким профилима у последњих двадесет година метода је нашла примену на скалама које одговарају бушотинским подацима или изданцима. Као најпогоднији седименти за овај тип истраживања су се показали карбонати јер су осетљиви на еустатичке промене, а основе секвенционе стратиграфије ...

    Serija organoselenijum trans-paladijum(II) kompleksa 1 (bis(2-(fenilselanilmetil)oksolan)dihloropaladijum(II)), 2 (bis(2-(fenilselanilmetil)oksan)dihloropaladijum(II)) i 3 (bis(2) ,2-dimetil-3-(fenilselanil)oksan)dihloropaladijum(II)) su korišćeni za ispitivanje reaktivnosti ovog specifičnog tipa kompleksa prema različitim bio-molekulima. Ovaj sistem je od posebnog interesa jer se jako malo zna o supstitucionim reakcijam organoselenijum paladijum(II) kompleksa sa trans konfiguracijom.

  • Microstructural and magnetic properties of electrospun hematite/cuprospinel composites

    Mira Ristić, Aleksandar Kremenović, Michael Reissner, Željka Petrović, Svetozar Musić (2020)
    Phase composition, microstructural and magnetic properties of electrospun hematite/cuprospinel composites were investigated. Samples were synthesized starting with 0 to 10 mol% of copper relative to iron. The round shape of reference electrospun fbres was preserved upon their heating up to 600 °C in air, whereas at 700 °C hollow substructure was additionally formed. In these reference samples the presence of hematite phase was detected by XRPD. A small amount (traces) of Fe3O4 /γ-Fe2O3 was also found, due to the ...

  • Asbestos-Based Pottery from Corsica: The First Fiber-Reinforced Ceramic Matrix Composite

    Philippe Colomban, Aleksandar Kremenović (2020)
    Asbestos-containing pottery shards collected in the northeast of Corsica (Cap Corse) and dating from the 19th century, or earlier, have been analyzed by SEM-EDS, XRPD, FTIR and Raman microspectroscopy. Blue (crocidolite) and white (chrysotile) asbestos fiber bundles are observed in cross-sections. Most of the asbestos is partly or totally dehydroxylated, and some transformation to forsterite is observed to occur, indicative of a firing above 800 C. Examination of freshly fractured pieces shows a nonbrittle fracture with fiber pull-out, consistent with ...

  • Mikrobiološki diverzitet kiselog jezera Robule i uticaj jezerske vode na oksidaciju sulfidnih minerala

    Srđan B. Stanković (2016-09-11)
    Jezero Robule, formirano u podnožju rudničke raskrivke Oštreljski planir (Rudnik bakra Bor), je nastalo kao posledica rudarskih aktivnosti. Mikrobiološki diverzitet ekstremno kiselog jezera Robule ispitivan je primenom kako klasičnih mikrobioloških metoda (svetlosna mikroskopija i kultivacija na selektivnim podlogama) tako i primenom savremene metode molekularne biologije (analiza polimorfizama terminalnih restrikcionih fragmenata; T-RFLP). Takođe, ispitivan je i potencijal i efikasnost jezerske vode u biološkom luženju mineralnog koncentrata, kao i u bioluženju uzoraka stare flotacijske jalovine Rudnika bakra Bor.Na osnovu dobijenih rezultata ...
