Status and tendencies under development and application of underground coal gasification-UCG
Podzemna gasifikacija uglja u Svetu poslednjih decenija doživljava znatnu ekspanziju u istraživanju i razvoju zbog uveliko iskorišćenih ležišta uglja i loših ekoloških efekata (pri sagorevanju u TE) na životnu okolinu. Srbija ima znatne rezerve uglja, a kada bi se za PGU koristile samo vanbilansne rezerve i otkopni ostaci bilansnih, jasno je kakvi bi bili ekonomski (a i energetski i ekološki) efekti. U radu su sagledane aktivnosti u Svetu na tom planu, pa smatramo da ima smisla i potrebe za primenu ove ...David Petrović, Lazar Kričak, Stefan Milanović, Jovan Marković, Nikola Simić.

EU Projekti -mogućnost i šansa za uključivanje i angažman naučnih kadrova iz geologije i rudarstva (posebno PMS-struke). Sa osvrtom na projekat RIS-DustRec- no 22009 iz oblasti EITRawMaterials (sekundarnih sirovina)
Dragan Radulović, Ivica Ristović, Gašper Tavčar, Davide Mombelli, Vladimir Jovanović, Dejan Todorović, Branislav Ivošević (2023)Velike količine prašine iz EAF peći se stvaraju u Evropi (1,3Mt), kao i u svetu (8,764Mt). Zbog visokog sadržaja Fe i Zn, čiji sadržaj često dostiže ukupno između 50 i 60 tež.%, EAF prašina je oduvek bila interesantna za reciklažu. Do sada, najčešće primenjivana metoda prerade EAF prašine je pirometalurški proces ekstrakcije Zn u Waelz pećima (85% tržišnog učešća). U radu je predstavlјen EIT Raw Materials projekat: RIS-DustRec-II, koji ima za cilј razvoj inovativnih tehnologija za odvajanje, ponovnu obradu ...Dragan Radulović, Ivica Ristović, Gašper Tavčar, Davide Mombelli, Vladimir Jovanović, Dejan Todorović, Branislav Ivošević.

Determination of parameters for wet grinding of phosphates in a laboratory ball mill and classification in a hydrocyclone
Компанија Elixir Прахово у свом производном процесу користи суво млевење сировог фосфата за своју производњу. Међутим, због повећане влаге у сировом фосфату која изазива потешкоће у фази сувог млевења, разматра се могућност увођења мокрог млевења у индустријском постројењу у Прахову. Влага улазног сировог фосфата варира од барже до барже, и креће се у границама 5-10% H2O, што је јако високо за процес сувог млевења а ствара одређене проблеме и на транспортном систему (систем редлерских транспортери). За сагледавање могућности мокрог млевења ...Predrag Lazić, Đurica Nikšić, Vladan Živković, Nemanja Todorović.

Dating of alluvial sediments from borehole at the lower course of the Sava river and indications of the connection between their genesis and climate changes in the Pleistocene
David Mitrinović, Jelena Zarić, Oliver Anđelković, Gyorgy Sipos, Dušan Polomčić, Milan Dimkić (2019)This paper analyses the way in which Pleistocene climate change and glaciations in Dinaric Mountains was reflected in the deposition of alluvial sediments in the Sava river Valley, using a case study of Belgrade Groundwater Source (BGS), the largest and most downstream alluvial water supply source along the Sava river. A stratigraphic analysis of the Quaternary sediments from two boreholes on this site, based on sediment dating, lithological members identification, grain size distribution analysis was performed.

Valorization of non-balanced coal reserves in Serbia for underground coal gasification
David Petrović, Lazar Kričak, Milanka Negovanović, Stefan Milanović, Jovan Marković, Nikola Simić, Ljubisav Stamenić (2019)In the name of a better and safer energy future, it is our responsibility to focus our knowledge and activities to save on imported liquid and gas fossil fuels, as well as coal on which energy security of Serbia is based. The rationalization in the use of available energy resources certainly positively affects economy and the environment of a country.

Interactions of Copper(II) Complexes of some Schiff base ligands with calf thymus DNA and bovine serum albumin
Joni prelaznih metala u kombinaciji sa različitim ligandima nude veliki broj mogućnosti za ispitivanje potencijalnih bioaktivnosti. Među jonima prelaznih metala, bakar je poznat kao endogeni metal za ljude, sa karakterističnim biološkim redoks aktivnostima i relativno jakim afinitetom za nukleobaze. Kompleksi bakra ispoljavaju svoju antitumornu aktivnost na nekoliko različitih načina, generišu veliku količinu ROS, što uzrokuje oksidativno oštećenje mitohondrija i biomakromolekula. Nađeno je da kompleksi bakra(II) imaju umeren do dobar afinitet vezivanja sa DNK, uglavnom putem interkalacije.Angelina Petrović, Aleksandar Mijatović, Rada Baošić, Jovana Bogojeski.

Analysis and Calculation of MMRS and Primary Gas Distribution Network in Urban Environment – Case Study Kučevo
Aleksandar Madžarević, Pavle Janković (2022)Oblast primene prirodnog gasa je veoma široka. Kao energent može se koristiti za proizvodnju energije u elektranama, toplanama i postrojenjima za kombinovanu proizvodnju energije ili za zadovoljavanje različitih toplotnih potreba u industriji i širokoj potrošnji. Gas se može upotrebiti i kao sirovina u hemijskoj i petrohemijskoj industriji, a tokom poslednjih decenija nalazi primenu i u saobraćaju kao pogonsko gorivo u SUS motorima. Sa ekološkog stanovišta, prirodni gas predstavlja najprihvatljiviji izvor energije u poređenju sa drugim fosilnim gorivima. Pri sagorevanju ...Aleksandar Madžarević, Pavle Janković.
