(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 ...
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 ...
Response surface optimisation for activation of bentonite with microwave irradiation / Optimalno faktorno planiranje procesa kiselinske aktivacije bentonita u mikrotalasnom polju
(Association of Chemical Engineers of Serbia, 2011)
In this study, the statistical design of the experimental method was applied on the process of acid activation of bentonite with microwave irradiation. The influence of activation parameters (time, acid normality and ...
Rheological behaviour of thermoplastic poly(ester-siloxane)s / Reološko ponašanje termoplastičnih poli(estar-siloksana)
(Association of Chemical Engineers of Serbia, 2010)
Two series of thermoplastic elastomers (TPES), based on poly(dimethylsiloxane) (PDMS) as the soft segment and poly(butylene terephthalate) (PBT) as the hard segment, were analyzed by dynamic mechanical spectroscopy. In the ...
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 ...
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, ...
