  • Assessment of environmental radioactivity and health hazard at Stara Planina region

    Slavko Dimovic, Boris Vakanjac, Ivana Jelic, Milena Rikalovic, Vesna Ristic-Vakanjac, Radoje Bankovic (2021)
    Циљ студије је био да се процени потенцијални ризик од зрачења у близини напуштених рудника уранијума, јаловишта или лежишта уранијума на Старој планини у Србији. За процену ризика одређено је неколико параметара: активност еквивалента радијума, Raeq, екстерни индекс опасности, Hex, брзина апсорбоване дозе гама зрачења, D, годишња ефективна доза на позадинској експозицији гама гама на отвореном, AEDoutdoor и ризик од рака током живота, ELCR. Добијени резултати су показали да сви узорци, осим једног, имају Raeq вредност и до два ...

  • Proučavanje razvića Bihaćkog i Cazinskog basena primenom gravimetrijskih podataka

    Snežana M. ignjatović, Ivana M. Vasiljević, Nevena R. Andrić-Tomašević, Ana S. Mladenović (2024)
    Bihaćki i Cazinski baseni su neogeni baseni, koji pripadaju spoljašnjim Dinaridima i formirani su tokom kasne faze razvoja Dinarida. Ovi baseni su od posebnog interesa zbog svoje geološke prošlosti i potencijalnih strukturnih karakteristika. U istraživanju, primenjeni su gravimetrijski podaci u clju boljeg razumevanja evolucije ovih basena. Primenom različitih postupaka matematičkih transformacija na gravimetrijskim podacima može se ustanoviti gravitacioni uticaj neogenih basena male gustine i mogu se detektovati strukture, koje su potencijalno vezane za njihovo formiranje. U ovom istraživanju, analiza ...

  • Micro- to nanoscale textures of gold in arsenopyrite and scorodite from the As-Au-Bi assemblage of Drenjak locality (Serbia)

    Ivana Jelić, Janez Zavašnik, Marina Lazarov, Alena Zdravković, Sabina Kovač, Jovica Stojanović, Aleksandar Pačevski (2023)
    Arsenopyrite and pyrite are important carriers of Au that is present in the form of microscopic and “invisible” gold. Such gold can be expected to be released upon the process of oxidation of these sulfides. In studied gold mineralization at Drenjak, related to the granitoids of the Oligocene-Miocene Kopaonik Ore District, the main arsenopyrite-pyrite-(bismuthinite) sulfide assemblage was formed in the quartz bodies and partly replaced by scorodite (FeAsO4·2H2O) and Bi-arsenate. With only up to 5 ppm of gold recorded ...

  • Investigation of accessory elements of representative petrologic radioactivity carriers at Stara Planina, Serbia

    Boris Vakanjac, Ivana Jelic, Milena Rikalovic, Vesna Ristic-Vakanjac, Dusan Nikezic, Zorana Naunovic, Slavko Dimovic (2019)
    Ова студија се бави обиљем најчешћих акцесорних елемената носилаца радиоактивности на Старој планини на четири дефинисане локације. Све истраживане локације имају повећану радиоактивност, већу од 200 цпс, до 1250 цпс. У свим испитиваним узорцима детектовани су следећи елементи и одређене њихове концентрације: Зр, Рб, В, Мо, Сн, Зн, Цу, Ас, Сб, Ба, Ни, Цр, В и Ти. Анализа је показала да су у зависности од узорка утврђене повишене концентрације свих детектованих елемената осим титана. Како се сви локалитети који ...

  • 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 ...

  • Surface functional groups and degree of carbonization of selected chars from different processes and feedstock

    Marija Ilić, Franz-Hubert Haegel, Aleksandar Lolić, Zoran Nedić, Tomislav Tosti, Ivana Sredović Ignjatović, Andreas Linden, Nicolai D. Jablonowski, Heinrich Hartmann (2022)
    The knowledge ofthe structural and chemical properties of biochars is decisive for their application as technical products. For this reason, methods for the characterization of biochars that are generally applicable and allow quality control are highly desired. Several methods that have shown potential in other studies were used to investigate two activated carbons and seven biochars from different processes and feedstock. The chars were chosen to cover a wide range of chemical composition and structural properties as a hardness ...

  • Overcoming the Low Oral Bioavailability of Deuterated Pyrazoloquinolinone Ligand DK-I-60-3 by Nanonization: A Knowledge-Based Approach

    Jelena R. Mitrović , Branka Divović-Matović, Daniel E. Knutson, Jelena B. Ðoković, Aleksandar Kremenović, Vladimir D. Dobričić, Danijela V. Randjelović, Ivana Pantelić, James M. Cook, Miroslav M. Savić, Snežana D. Savić (2021)
    Poor water solubility of new chemical entities is considered as one of the main obstacles in drug development, as it usually leads to low bioavailability after administration. To overcome these problems, the selection of the appropriate formulation technology needs to be based on the physicochemical properties of the drug and introduced in the early stages of drug research. One example of the new potential drug substance with poor solubility is DK-I-60-3, deuterated pyrazoloquinolinone, designed for the treatment of various neuropsychiatric ...
