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 ...
Mean heat transfer coefficients during the evaporation of 1,1,1,2-tetrafluoroethane (R-134a) in a plate heat exchanger
(Serbian Chemical Society, 2007)
In this study the transfer coefficient of evaporation heat of the refrigerant 1,1,1,2-tetrafluoroethane (R-134a) in a vertical plate heat exchanger was experimentally investigated. The results are presented as the dependancy ...
The effect of particle structure on apparent density of electrolytic copper powder / Uticaj strukture čestica na nasipnu masu elektrolitički dobijenog bakarnog praha
(Serbian Chemical Society, 2001)
The quantitative microstructural analysis and the sieve analysis of copper powder as well as the scanning electron microscopy analysis of the copper powders particles were performed. It was found that the structure 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 ...
On the kinetics of the hydrogen evolution reaction on zinc in sulfate solutions
(Belgrade : Serbian Chemical Society, 2001)
The kinetics and mechanism of the hydrogen evolution reaction (her) were studied on zinc in 1.0 mol dm-3 Na2SO4 at 298 K, in the pH range 4.4 - 10. It was found that a combination of classical potentiostatic steady-state ...
Pressure drop during evaporation of 1,1,1,2-tetrafluoroethane (R-134a) in a plate heat exchanger
(Serbian Chemical Society, 2007)
Experimental results for the pressure drop during the evaporation of the refrigerant 1,1,1,2-tetrafluoroethane (R-134a) in a vertical plate heat exchanger are presented in Ms paper. The influences of mass flux, heat flux ...
The surface energy of disperse cadmium electrodeposits formations / Површинска енергија електрохемијског формирања дисперзног талога кадмијума
(Serbian Chemical Society, 2005)
The surface energy of disperse cadmium electrodeposits formation was determined by using a procedure described earlier.1,2 It was shown that the surface energy strongly depends on the composition of the solution from which ...
Effect of non-stationary current regimes on the morphology of silver electrodeposits / Efekat nestacionarnih strujnih režima na morfologiju taloga srebra
(Serbian Chemical Society, Belgrade, 2009)
This work is concerned with the use of reverse current regimes in order to form small-grained and compact silver deposits during the electrorefining process. Several parameters were varied, i.e., i) anodic overpotential, ...
Mixtures of methanol and 2-propanol as a potential fuel for direct alcohol fuel cells / Smeša metanola i 2-propanola kao potencijalno gorivo u gorivim spregovima sa alkoholom
(Serbian Chemical Society, Belgrade, 2007)
The electrochemical oxidation of methanol, 2-propanol, and their mixtures was investigated on a Pt/C thin film electrode in acid solution. It was confirmed that the oxidation of 2-propanol commences at less positive ...
Acentric factor estimation from the corresponding states principle
