Automatic feeder for domestic and wild animals on pastures / Automatski uređaj za prihranu domaćih i divljih životinja na pašnjacima
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2020)
This paper presents a prototype of an automatic feeder for domestic and wild animals in organic farming. A simple, self-contained domestic and wild animal feeder was presented that has fully autonomous operation for up to ...
Tools for optimizing the operating conditions of waste-to-energy plant / Alati za optimizaciju radnih uslova postrojenja za energetsko iskorišćenje otpada
(Engineering Society for Corrosion, Belgrade, Serbia, 2020)
The efficient use of energy and resources is important from the point of environmental responsibility, but at the same time, it can be an opportunity towards obtaining economic value. Waste-to-energy (WtE) plants have the ...
Synthesis, solvent interactions and computational study of monocarbohydrazones
(Springer International Publishing Ag, Cham, 2020)
Carbohydrazones are compounds that are increasingly studied due to their wide potential biological activity. Monocarbohydrazones (mCHs), as one of the carbohydrazone derivatives, so far have been poorly investigated. For ...
Characterization of PM(2.5)sources in a Belgrade suburban area: a multi-scale receptor-oriented approach
(Springer Heidelberg, Heidelberg, 2020)
Designated as the most harmful for health, PM(2.5)aerosol fraction was a subject of our study. It was collected for all four seasons during 2014/15 in the suburban area of Belgrade (Serbia) and analysed for Al, Si, P, S, ...
Effects of waste sulfur content on properties of self-compacting concrete
(Consejo Superior Investigaciones Cientificas-Csic, Madrid, 2020)
Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore ...
Porous cordierite-supported polyethyleneimine composites for nickel(II) and cadmium(II) ions removal
(Desalination Publ, Hopkinton, 2020)
Industrial/technological growth is directly connected with environmental pollution, but its influence can be minimized through pollution abatement approaches such as the treatment of industrial wastewater. In this study, ...
Photocatalytic degradation of methylene blue under natural sunlight using iron titanate nanoparticles prepared by a modified sol-gel method
(Royal Soc, London, 2020)
The aim of this work was to synthesize semiconducting oxide nanoparticles using a simple method with low production cost to be applied in natural sunlight for photocatalytic degradation of pollutants in waste water. Iron ...
Sintering, crystallization and foaming of La2O3 center dot SrO center dot 5B(2)O(3) glass powders: effect of the holding time
(Elsevier, Amsterdam, 2020)
Sintering, crystallization and foaming of nano glass powders with composition La2O3 center dot SrO center dot 5B(2)O(3) were studied by hot stage microscopy (HSM) and simultaneous thermal analysis (DTA-TG) under non-isothermal ...
Thin-layer chromatography on reversed phase in the characterization of retention behaviour, lipophilicity, and pharmacokinetics of cyanoacetamide derivatives
(Journal of the Chilean Chemical Society, 2020)
Biological activity of a molecule is closely related to its lipophilicity. This significant parameter was determined for a group of potentially bioactive N-(4-phenylmonosubstituted)-2-cyanoacetamides applying thin-layer ...
Biosynthesis of silver-based nanoparticles on polypropylene non-woven material for efficient antimicrobial activity / БИОСИНТЕЗА НАНОЧЕСТИЦА НА БАЗИ СРЕБРА НА НЕТКАНОМ ПОЛИПРОПИЛЕНСКОМ МАТЕРИЈАЛУ ЗА ЕФИКАСНУ АНТИМИКРОБНУ АКТИВНОСТ
(Serbian Chemical Society, 2023)
The outbreak of the COVID 19 pandemic confirmed the importance of personal protective equipment including the respiratory face masks as barriers to pathogens. Taking into account that face masks are mainly composed of ...
