Do We Need More Ambition for the Renewable Energy Transition in Serbia? Foundations of Energy Governance and Planning
(Beograd: Savez energetičara, 2021)
Obnovlјiva energija je predložena kao primarni pristup za dekarbonizaciju energetskog sistema i razdvajanje potrošnje energije od emisije gasova sa efektom staklene bašte, kako u energetskoj literaturi, tako i u praksi. ...
Nanostructured constituents of ZnO-based varistors prepared by mechanical attrition
(Elsevier, 1994)
Nanostructured powders, with crystallite size of ZnO, spinel and γ-Bi2O3 phases below 100 nm, were obtained by the mechanical attrition of ZnO varistor powders prepared by method of directed synthesis of the constituent ...
Transesterification of used cooking sunflower oil catalyzed by hazelnut shell ash
(Elsevier, 2022)
Hazelnut shell ash was investigated as a new base catalyst for the transesterification of used cooking sunflower oil to biodiesel. To understand its catalytic properties, the prepared ash was characterized by EDX, XRD, ...
Optimizacija parametara sinteze nanokompozita na bazi bakterijske nanoceluloze/Fe3O4
(Beograd : Savez inženjera i tehničara Srbije, 2021)
Napredak u mnogim oblastima tehnike i tehnologije je blisko povezan sa razvojem novih ili unapređenjem postojećih materijala. Imajući u vidu široku primenu bakterijske nanoceluloze (BNC) u raznim oblastima svakodnevnog ...

(Belgrade : Institute of Technical Sciences of SASA, 2021)
Resveratrol, polyphenol from stilbene family, has demonstrated beneficial effects on human health in numerous studies. Among these effects are cardioprotective, anti-cancer, neuroprotective, antimicrobial and other. In ...
Point defects and their effect on dielectric permittivity in strontium titanate ceramics
(Belgrade : ETRAN, 2021)
The origin of dielectric properties of strontium titanate ceramics is investigated using DFT calculations in periodic system. It was determined that the main factors contributing to the increase in dielectric permittivity ...
The thermophysical properties of primary phase in lithium germanium phosphate glass
(Belgrade : ETRAN, 2021)
The selected lithium germanium-phosphate glass was prepared by a conventional melt-quenching technique. The XRD method was employed to confirm the glass was obtained and to reveal crystalline phases during heat treatment. ...
Phase morphological and antimicrobial properties of HAp-TiO2 nanomaterials obtained by different synthesis route
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
Due to the growing number of people infected with the new corona virus in the world, there is an increase in bacterial infections, which weakens the immunity. New knowledge about simple and low cost synthesis methods of ...
Nanoparticles: Potential for Use to Prevent Infections
(Cham : Springer International Publishing, 2022)
One of the major issues related to medical devices and especially urinary stents are infections caused by different strains of bacteria and fungi, mainly in light of the recent rise in microbial resistance to existing ...
Electrochemical characteristics of rechargeable polyaniline/lead dioxide cell
(Elsevier, 2012)
Electrochemically synthesized polyaniline (PANI) and lead dioxide have been investigated as electrode materials for PANI/1.1 M H2SO4; 0.5 M (NH4)2SO4/PbO2 rechargeable cell. At constant current charge/discharge of the cell, ...
