Calculation and optimization of the copper (II) sulphate monohydrate from copper (II) sulphate pentahydrate production process in a fluidized bed dryer / Proračun i optimizacija procesa proizvodnje bakar(II)-sulfat-monohidrata iz bakar(II)-sulfat-pentahidrata u sušnicama sa fluidizovanim slojem
(Association of Chemical Engineers of Serbia, 2015)
In this paper the process of the copper (II) sulphate monohydrate from copper (II) sulphate pentahydrate (also known as a Blue vitriol or Bluestone) production was analyzed. Copper (II) sulphate pentahydrate is one of the ...
The nano-wetting aspect at the liquid-metal/sic interface
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2015)
The wetting process on the nano-scale, as an initial and essential step in liquid metal/ceramic joining, is discussed here. Thanks to recent breakthroughs in experimental techniques with nanometre resolution, questions ...
Optimization of (-galactosidase production from lactic acid bacteria / Optimizacija proizvodnje (-galaktozidaze pomoću bakterija mlečne kiseline
(Association of Chemical Engineers of Serbia, 2015)
(-galactosidase, commonly known as lactase, represents commercially important enzyme that is prevalently used for lactose hydrolysis in milk and whey. To the date, it has been isolated from various sources. In this study ...
Cfd analysis and flow model reduction for surfactant production in helix reactor
(Savez hemijskih inženjera, Beograd, 2015)

The goal of this study was to prepare a CaO·ZnO catalyst containing a small amount of K2CO3 and analyze its activity for biodiesel synthesis. The catalyst was prepared using the following procedure: CaO and ZnO (mole ratio ...
Influence of clay organic modifier on the morphology and performance of poly(epsilon-caprolactone)/clay nanocomposites
(Srpsko hemijsko društvo, Beograd, 2015)
Two series of poly(epsilon-caprolactone) poly(oxepan-2-one) nanocomposites with different organo-modified clays (1 to 8 wt. %) were prepared by the solution casting method. Organoclays with polar (Cloisite (R) C30B) and ...
Establishing Dependences between Different Lipophilic Parameters of New Potentially Biologically Active N-Substituted-2-Phenylacetamide Derivatives by Applying Multivariate Methods
(Oxford Univ Press Inc, Cary, 2015)
Lipophilicity, a very important parameter in the potential biological activities of molecules, was investigated for newly synthesized N-substituted-2-phenylacetamide derivatives. The determination was carried out in two ...
