Determination of the ozone volumetric mass transfer coefficient in bubble column with two-fluid nozzle gas distributor / Određivanje zapreminskog koeficijenta prenosa mase ozona u barbotažnoj koloni sa dvofluidnom mlaznicom
(Association of Chemical Engineers of Serbia, 2015)
Experimental investigation of gas-liquid mass transfer of ozone in water, in bubble column with two-fluid nozzle gas distributor (BKDM), under different operating conditions, is presented in this work. The main objective ...
Electrical conductivity of poly (L lactic acid) and poly (3-hydroxybutyrate) composites filled with galvanostatically produced copper powder
(Association of Chemists and Chemical Engineers of Serbia, 2018)
This manuscript presents experimental studies of composite materials based on poly (L lactic acid) (PLLA) and poly (3-hydroxybutyrate) (PHB) matrices filled with electrolytic copper powder, having a very high dendritic ...
Momentum, heat, and mass transfer analogy for vertical hydraulic transport of inert particles / Analogija prenosa količine kretanja, toplote i mase pri vertikalnom hidrauličkom transportu inertnih čestica
(Association of Chemical Engineers of Serbia, 2014)
Wall-to-bed momentum, heat and mass transfer in the vertical liquid-solids flow, as well as in the single phase flow, were studied. The aim of this investigation was to establish the analogy among those phenomena. Also, ...
Bioremediation of soil polluted with crude oil and its derivatives: Microorganisms, degradation pathways, technologies / Bioremedijacija zemljišta kontaminiranog naftom i naftnim derivatima: mikroorganizmi, putanje razgradnje, tehnologije
(Association of the Chemical Engineers of Serbia, 2012)
The contamination of soil and water with petroleum and its products occurs due to accidental spills during exploitation, transport, processing, storing and use. In order to control the environmental risks caused by petroleum ...

Phenolic compounds and carotenoids in pumpkin fruit and related traditional products
(Association of Chemical Engineers of Serbia, 2016)
Pumpkin fruit is used in a diet since ancient times especially in rural communities. The major contributory factors of nutritional and medicinal value of pumpkins are carotenoids, polysaccharides, vitamins, minerals, and ...
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 ...
Impact of the poly(propylene oxide)-b-poly(dimethylsiloxane)-b-poly-(propylene oxide) macrodiols on the surface-related properties of polyurethane copolymers
(Assoc Chemical Engineers Serbia, Belgrade, 2016)
Segmented thermoplastic polyurethane copolymers (PURs) were synthesized using 4,4'-methylenediphenyl diisocyanate and 1,4-butanediol as the hard segment and alpha,omega-dihydroxy-poly(propylene oxide)-b-poly(dimethylsilo ...
Surface characterization, hemo- and cytocompatibility of segmented poly(dimethylsiloxane)-based polyurethanes / Površinska karakterizacija, hemo- i citokompatibilnost segmentiranih poliuretana na bazi poli(dimetilsiloksana)
(Association of Chemical Engineers of Serbia, 2014)
Segmented polyurethanes based on poly(dimethylsiloxane), currently used for biomedical applications, have sub-optimal biocompatibility which reduces their efficacy. Improving the endothelial cell attachment and blood-contacting ...
