Tourbillion in the phase space of the Bray-Liebhafsky nonlinear oscillatory reaction and related multiple-time-scale model
(Univ Kragujevac, Fac Science, Kragujevac, 2013)
The mixed-mode dynamical states found experimentally in the concentration phase space of the iodate catalyzed hydrogen peroxide decomposition (The Bray-Liebhafsky oscillatory reaction) are discussed theoretically in a ...
Testing microbiological and chemical parametars of the sediment of microbial fuel cell / Mikrobna gorivna ćelija – hemijska i mikrobiološka karakterizacija sedimenta
(Serbian Chemical Society, Belgrade / Srpsko hemijsko društvo, Beograd, 2019)
Microbial fuel cells (MFCs) represent new potential energy sources through which electricity is generated, and among numerous advantages is that the emission of harmful gases is missing. MFC is a type of biological fuel ...
The analysis of forming PVB-SiO2 nanocomposite fibers by the electrospinning process / Analiza formiranja PVB-SiO2 nanokompozitnih vlakana pomoću elektrospining procesa
(Vojnotehnički institut, Beograd, 2011)
The poly (vinyl butyral)-silica (PVB-SiO2) nanofibers were obtained by the electrospinning process. The experiments were carried out with PVB solution in concentration of 10 wt.% where ethanol was used as the solvent. The ...
Ispitivanje naftnih zagadjujućih supstanci u uzorcima sedimenta na lokalitetu Toplane Novi Beograd / Determination of petroleum pollutants in sediment samples at the site of heating plant “Novi Beograd”
(Srpsko hemijsko društvo, Karnegijeva 4/III, Beograd, Srbija / Serbian Chemical Society, Karnegijeva 4/III, Belgrade, Serbia, 2018)
Nafta i naftni derivati kao što su dizel, benzin i mazut mogu dospeti u vodu, zemljište i sediment i predstavljaju rizik za životnu sredinu i čoveka [1-3]. Tehnologijom bioremedijacije, koristeći prirodnu sposobnost ...
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 ...
