Model of a nonlinear reaction system with autocatalysis and autoinhibition: Stability of dynamic states / Nelinearni reakcioni sistem sa autokatalizom i autoinhibicijom - stabilnost dinamičkih stanja
(Association of Chemical Engineers of Serbia, 2012)
Self-regulation, achieved through positive (autocatalytic) or negative (autoinhibitory) feedback is commonly encountered in natural, technological and economic systems. The dynamic behavior of such systems is often complex ...
Freshwater Cyanobacterial blooms and Cyanotoxin production in Serbia in the past 25 years
(University of Novi Sad, Department of Geography, Tourism and Hotel Management, 2007)
Since 1980 cyanobacterial blooms occurred in a large number of reservoirs lakes and water flows (rivers and channels) in Serbia. Among 83 water ecosystems examined, 58 were found in blooming condition almost every year ...
Speciation of selected trace and major elements in lignite used in 'Nikola Tesla A' power plant (Obrenovac, Serbia) / Specijacija odabranih mikro- i makroelemenata u uzorcima lignita termoelektrane 'Nikola Tesla A' (Obrenovac, Srbija)
(Serbian Chemical Society, 2005)
Four samples of milled lignite used in the "Nikola Tesla A" power plant located in Obrenovac near Belgrade, were subjected to a five-step sequential extraction, comprising of the following phases: distilled water, 1M ...
Chemical composition, antibacterial and antifungal activity of the essential oils of Cotinus coggygria from Serbia / Hemijski sastav, antibakterijska i antifungalna aktivnost etarskih ulja biljne vrste Cotinus coggygria iz Srbije
(Serbian Chemical Society, 2007)
Essential oils from leaves with young branches of Cotinus coggygria Scop. from two localities in Serbia (Deliblatska peščara and Zemun), obtained by hydrodistillation, were analyzed by GC-MS. Thirty-one component were ...
Porous poly(methylmethacrylate) and poly(methylmethacrylate-co-acrylamide) / Porozni poli(metilmetakrilat) i poli(metilmetakrilat-co-akrilamid)
(Association of Chemical Engineers of Serbia, 2006)
The characteristics of two types of porous polymers: poly(methyl methacrylate) and copolymers of methyl methacrylate and acrylamide were investigated in this study. Poly(methyl methacrylate) was synthesized in suspension, ...
A novel macroporous polymer-inorganic nanocomposite as a sorbent for pertechnetate ions
(The Royal Society of Chemistry, 2017)
A novel magnetic macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (mPGME) was prepared by suspension copolymerization and functionalized with diethylenetriamine (mPGME-deta). The samples were ...
Pressure drop in packed beds of spherical particles at ambient and elevated air temperatures / Pad pritiska u pakovanom sloju sferičnih čestica na sobnoj i povišenim temperaturama
(Association of the Chemical Engineers of Serbia, 2015)
The aim of this work was the experimental investigation of the particle friction factor for air flow through a packed bed of particles at ambient and elevated temperatures. The experiments were performed by measuring the ...
Microwave Synthesis of Unusually-Shaped Crystalline RuO2 Supercapacitor
(Academician Evgeni Budevski Institute of Electrochemistry and Energy Systems Bulgarian Academy of Sciences, Sofia, Bulgaria, 2015)
One-step simple temperature-controlled microwave synthesis was applied to prepare nanocrystalline RuO2 dispersion from aqueous RuCl3. RuO2 dispersion was subjected to dynamic light scattering in order to analyze the ...
Obtaining nano calcium phosphate/poly(dl-lactide-coglycolide) composite biomaterial by sonochemical deagglomeration
(Belgrade: Institute of Technical Sciences of SASA, 2007)
Nanoparticles have several advantages over the microparticles in interactions of thebiomaterial with the organism. The response of the organism depends on the interaction of thebiomaterial with the surrounding tissue and ...
Investigation on the Electrochemical Behaviour and Deposition Mechanism of Neodymium in NdF3–LiF–Nd2O3 Melt on Mo Electrode
(MDPI, 2020)
Neodymium was electrochemically deposited from NdF3–LiF–Nd2O3 molten salt electrolyte onto the Mo electrode at temperatures close to 1273 K. Cyclic voltammetry and chronoamperometry measurements were the applied electrochemical ...
