The growth of ruby single crystals / Раст монокристала рубина
(Serbian Chemical Society, 2005)
Ruby (Cr:Al2O3) single crystals were grown by the Czochralski technique in an argon atmosphere. The critical crystal diameter dc = 1.0 cm and the critical rate of rotation ωc = 20 rpm were calculated by equations of the ...
The gas holdup in a multiphase reciprocating plate column filled with carboxymethylcellulose solutions / Утицај концентрације раствора и степена полимеризације карбоксиметилцелулозе на садржај гаса у реактору са вибрационом мешалицом
(Serbian Chemical Society, 2005)
Gas holdup was investigated in a gas-liquid and gas-liquid-solid reciprocating plate column (RPC) under various operation conditions. Aqueous carboxymethylcellulose (sodium salt, CMC) solutions were used as the liquid ...
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 ...
A pseudo-fluid representation of vertical liquid-coarse solids flow / Vertikalno kretanje tečnosti i čvrstih čestica tretirano kao pseudo-fluid
(Serbian Chemical Society, 2005)
The pseudo–fluid concept has been applied for the prediction of the pressure gradient and voidage in vertical liquid-coarse solids flow. Treating the flowing mixture as a single homogenous fluid, the correlation for the ...
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 ...
A new dimensionless group for the estimation of the current density distribution in an electrochemical cell / Нова бездимензиона група за процену расподеле густине струје у електрохемијској ћелији
(Serbian Chemical Society, 2005)
A new dimensionless group for the estimation of the current density distribution in an electrochemical cell is defined as the ratio of the sum of the absolute values of the anodic and cathodic overpotentials to the overall ...
