Proučavanje razvića Bihaćkog i Cazinskog basena primenom gravimetrijskih podataka
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 ...Snežana M. ignjatović, Ivana M. Vasiljević, Nevena R. Andrić-Tomašević, Ana S. Mladenović.

Back-arc underplating provided crustal accretion affecting topography and sedimentation in the Adria microplate
Paolo Mancinelli, Vittorio Scisciani, Cristina Pauselli, Gérard M. Stampfli, Fabio Speranza, Ivana Vasiljević (2021)Supported by evidence of deep crustal sources for the observed magnetic anomalies in Central Italy and by outcropping gabbros in the Croatian archipelago, we model the observed gravity and magnetic anomalies in the Central Adriatic Sea and surroundings. We suggest that the major magnetic anomalies in the area are related to a wide underplating and propose that this volume represents the first stage of the back-arc Adria continental breakup in Early Permian times. During the Palaeotethys-Adria collision, underplating has ...... topography and sedimentation in the Adria microplate Paolo Mancinelli, Vittorio Scisciani, Cristina Pauselli, Gérard M.

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 ...Ivana Jelić, Janez Zavašnik, Marina Lazarov, Alena Zdravković, Sabina Kovač, Jovica Stojanović, Aleksandar Pačevski.

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 ...Atomic force microscopy, Insulating properties, Nanofriction and wear, Natural two dimensional materials, Phyllosilicates, PyrophylliteBorislav Vasić, Radoš Gajić, Ivana Milošević, Žarko Medić, Marina Blagojev, Marko Opačić, Aleksandar Kremenović, Dejan Lazić.

Fuzzy expert analysis of the severity of mining machinery failure
Mining machinery failure is almost an everyday occurrence. Usually the failures bare certain consequences, which require additional financial costs to repair and restore the system to its operational state. The consequences are viewed through negative and damaging effects a failure has on the machine, health and safety of the employees, work environment, and on the environment. The removal of the consequences of the failure requires additional financial investment, which has a negative impact on the company’s business. In order ......

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.

Agates of the Lece Volcanic Complex (Serbia): Mineralogical and Geochemical Characteristics
Agate veins and nodules occur in the Lece Volcanic Complex (Oligocene-Miocene) situated in the south of Serbia and occupying an area of 700 km2. This volcanic complex is composed predominantly of andesites, with sporadic occurrences of andesite-basalts, dacites and latites, and features agate formations that have been very little investigated. This study focuses on five selected agate occurrences within the Lece Volcanic Complex, employing optical microscopy, scanning electron microscopy (SEM), X-ray powder diffraction analysis, inductively coupled plasma mass spectrometry ...Zoran Miladinović, Vladimir Simić, Nenad Nikolić, Nataša Jović Orsini, Milena Rosić.

Kvantitativna ocena režima i bilansa podzemnih voda u aluvijonu Velike Morave od Bagrdana do ušća u Dunavu
Aleksandar Balubdžić (2024)Aluvijalni sedimenti velikih reka raspolažu značajnim količinama podzemnih voda, što je zajedno sa površinskim vodama dozvolilo razvoj naselja i ljudskih aktivnosti. Ovaj razvoj uslovljava veće potrebe za vodnim resursima i njihovim kvalitetom. Sa povećanjem eksploatacije podzemnih voda, uticaj iste je značajniji i može da dovede do opadanja nivoa podzemnih voda i pogoršanja kvaliteta. Aluvijon Velike Morave ima značajno rasprostranjenje, usled čega predstavlja važno ležište izdanskih voda sa velikim eksploatacionim mogućnostima.

Modeliranje disperzije dimnih gasova iz termoelektrane ,, Nikola Tesla”
Milica Kostić (2024)Termoelektrane na ugalj, iako značajan izvor električne energije, predstavljaju veliki izazov zbog zagađenja koje uzrokuju. Glavni uzrok zagađenja je neumerena ljudska potreba za energijom i resursima, što dovodi do emisije različitih zagađivača u atmosferu, uključujući okside ugljenika, sumpora, azota, kao i lebdeće čestice i toksine. Ove emisije imaju negativan uticaj na kvalitet vazduha, zdravlje ljudi i životnu sredinu. Procena uticaja termoelektrana na ugalj na životnu sredinu je zakonska obaveza i ključna za smanjenje tih negativnih efekata. Ovaj dokument analizira potencijalne ...... SEKULIĆ, Z. Ž., 2015.
