Синтеза и карактеризација керамике на бази сфена
Jelena R. Pantić (2015-07-10)Механохемијска активација стехиометријске смеше реактаната TiO2, SiO2 и CaCO3 показала се као веома успешна и једноставна метода за добијање сфена (CaTiSiO5). На основу мерења релативних густина свих синтерованих узорака установљено је да максималну густину од 93,9 % имају узорци који су активирани 30 минута и синтеровани на 1200 °С. Микроструктурном анализом, тј. анализом слика синтерованих узорака активираних 30 минута, које су добијене скенирајућом електронском микроскопијом, опажа се бимодална расподела величине зрна, са просечном величином од 3 μm, односно 5 ...сфен, механохемија, Ритвелдова метода, оптичка спектроскопија, микроструктурна анализа, фазна трансфоpмација, чврсти раствори... pigments prepared via precursor mechanochemical activation.

Long-term planning methodology for improving wood biomass utilization
The insufficiently developed forest management system is often followed by undeveloped forest resources supply chain and insufficient institutional support. These cause inefficient usage of fuel-wood as well as huge amounts of unused forest residues. In order to achieve optimal and long-term sustainable utilisation of biomass, an original methodology based on the interaction of mathematical optimization and backcasting approach has been developed. Mathematical optimization is used for both generation and consideration of techno-economic parameters of the forest biomass supply chain. ...Vladimir Vukašinović, Dušan Gordić, Marija Živković, Davor Koncalović, Dubravka Živković.

Tectonic evolution of the Vršac Mts. (NE Serbia): Inferences from field kinematic and microstructural investigations
The Vršac Mts. in NE Serbia represent the key area to investigate structural relations between the Northern Serbo-Macedonian Subunit and Supragetic Unit of the Dacia Mega-Unit. The geodynamic events during the Variscan orogeny in the Late Paleozoic colligated the two units and led to their metamorphic differentiation. The Late Cretaceous extension exhumed the medium-grade Serbo-Macedonian metamorphic rocks and structurally juxtaposed them against the low-grade metamorphosed basement of the Supragetic Unit along an E-dipping shear zone, which outcrops in the ...severna srpsko-makedonska subjedinica, supragetikum, kinematska analiza, multifazna ekstenzionalna deformacija...

Synthesis of MnCo2O4 nanoparticles as modifiers for simultaneous determination of Pb(II) and Cd(II)
The porous spinel oxide nanoparticles, MnCo2O4, were synthesized by citrate gel combustion technique. Morphology, crystallinity and Co/Mn content of modified electrode was characterized and determined by Fourier transform infra-red spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), X-ray diffraction pattern analysis (XRD), simultaneous thermogravimetry and differential thermal analysis (TG/DTA). Nanoparticles were used for modification of glassy carbon electrode (GCE) and new sensor was applied for simultaneous determination of Pb(II) and Cd(II) ions in water samples with the ...Vesna Antunović, Marija Ilić, Rada Baošić, Dijana Jelić, Aleksandar Lolić.

Energetska tranzicija u domaćinstvima: analiza usaglašenosti Srbije sa paketom „Čista energija za sve Evropljane“ / Energy Transition in Households: Analysis of Serbia’s Compliance with the „Clean Energy for All Europeans“ Package
Zahvaljujući svojoj složenosti i heterogenosti, sektor domaćinstva predstavlja neizostavnu tačku u politikama energetske tranzicije. U Evropskoj uniji, potrošnja energije u domaćinstvima čini oko 26% finalne potrošnje energije, dok u Srbiji ovaj sektor ima najveći udeo u finalnoj potrošnji, što čini oko trećinu finalne potrošnje. Primenom mera energetske efikasnosti moguće je ostvariti značajne energetske uštede, što zajedno sa smanjenjem i supstitucijom upotrebe fosilnih goriva vodi manjem doprinosu klimatskim promenama i značajnom smanjenju zagađenja vazduha.

Towards more sustainable district heating systems in Serbia - Options and obstacles
The major share of energy consumed in the building environment is dedicated to meeting heating needs, which makes this sector one of the key players in the transformation of the whole energy system. The accurate approach to the transition process assumes acting on both the demand and supply sides. Lately, the supply side has received more attention, as its transformation is one of the key steps of the energy transition process.
