Synthesis and characterization of copolymer hydrogels of chitosan, itaconic acid and N-isopropylacrylamide / Sinteza i karakterizacija kopolimernih hidrogelova hitozana, itakonske kiseline i N-izopropilakrilamida
(Association of Chemical Engineers of Serbia, 2011)
This paper deals with the synthesis of copolymer hydrogels of N-isopropylacrylamide, itaconic acid and chitosan. During synthesis, pH of the reaction solution and temperature were varied. It was found that the reaction at ...
Mechanical and microstructural properties of the fly-ash-based geopolymer paste and mortar
(Institute of Metals and Technology, 2013)
In this paper we have investigated the influence of synthesis parameters on the mechanical properties of the fly-ash-based geopolymer paste and mortars. Moreover, the influence of an addition of limestone sand on the ...
Liquid transfer properties of textile fabrics as a function of moisture content
(Savez hemijskih inženjera, Beograd, 2020)
Liquid transport in textile fabrics determines thermal comfort during high physical activity of a person when liquid perspiration is produced and needs to be transferred away from the skin to keep the thermal balance. In ...
1,3-Propanediammonium [μ4-1,2,4,5-benzenetetracarboxylato(4-) ]copper(II) dihydrate with a microporous structure
(Serbian Chemical Society, 2005)
Crystal structure analysis of the title complex, (H3NC 3H6NH3)[Cu{C6H2(COO) 4}] ·2H2O, showed that the structure is built up from Cu(II) and tetradentate 1,2,4,5-benzenetetracarboxylate(4-) (btc) ions forming a 3D ...
Methanol oxidation at platinum electrodes in acid solution: Comparison between model and real catalysts / Oksidacija metanola na platinskim elektrodama u kiseloj sredini - poređenje model i realnih katalizatora
(Serbian Chemical Society, Belgrade, 2006)
Methanol oxidation in acid solution was studied at platinum single crystals, Pt(hkl), as the model catalyst, and at nanostructural platinum supported on high surface area carbon, Pt/C, as the real catalyst. The linear ...
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 ...
Utilization of baker's yeast (Saccharomyces cerevisiae) for the production of yeast extract: Effects of different enzymatic treatments on solid, protein and carbohydrate recovery / Primena pekarskog kvasca (Saccharomyces cerevisiae) za dobijanje kvaščevih ekstrakata - uticaj različitih parametara enzimske hidrolize na sadržaj suve materije, proteina i ugljenih hidrata
(Serbian Chemical Society, Belgrade, 2007)
Yeast extract (YE) was produced from commercial pressed baker's yeast (active and inactivated) using two enzymes: papain and lyticase. The effects of enzyme concentration and hydrolysis time on the recovery of solid, protein ...
Kinetics and mechanism of As2S2 oxidation / Кинетика и механизам процеса оскидације једињења Аs2S2
(Serbian Chemical Society, 2005)
The kinetics of realgar (As2S2) oxidation was studied under isothermal and non-isothermal conditions. The obtained values of the activation energy indicate that the process occurs in the kinetic domain with the realgar ...
Experimental Investigation of Microstructure and Phase Transitions in Ag-Cu-Zn Brazing Alloys
(Springer, 2018)
Microstructure and phase transitions of selected brazing alloys from the Ag-Cu-Zn ternary system were investigated. Four ternary alloys with silver content in the compositional range from 25 to 60 wt.% were studied using ...
Thermal degradation of coordination polymer [Cd(N-Boc-gly)(2)(H2O)(2)](n)
(Elsevier Science Bv, Amsterdam, 2011)
Multi-step thermal degradation of coordination polymer [Cd(N-Boc-gly)(2)(H2O)(2)](n) in non-isothermal conditions was studied. The kinetic parameters were determined from the thermal decomposition data using the isoconversion ...
