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 ...
MS analysis of biindenylidenes / MS analiza biindenilidena
(Serbian Chemical Society, Belgrade, 2004)
Biindenylidene isomers are components of pyrolysis oils. The mass spectra were recorded and the fragmentation of the following biindenylidene isomers (E)-2,3,2’,3’-tetrahydro- [1,1’]biindenylidene (Z)-2,3,2’,3’-tetrahydr ...
Ion/surface collisions: An alternative to gas-phase collisional activation in mass spectrometry
(Serbian Chemical Society, 2001)
Collisions of ions at solid surfaces result in a number of phenomena, of which surface-induced dissociation (SID) is the most important. SID has been shown to be a viable alternative to collision-induced dissociation (CID) ...
The effect of the composition of the dispersing medium of oxide sols on the electrocatalytic activity of sol-gel obtained RuO2-TiO2/Ti anodes / Uticaj sastava disperzne sredine oksidnih solova na elektrokatalitičku aktivnost RuO2-TiO2/Ti anoda dobijenih sol-gel postupkom
(Serbian Chemical Society, 2001)
The influence of the addition of methanol, ethanol, 1-propanol and 2-propanol to the dispersing medium of a mixture of RuO2 and TiO2 sols on the electrochemically active surface area for proton exchange, as well as on the ...
Primary and secondary dendrite spacing of Ni-based superalloy single crystals
(Serbian Chemical Society, 2009)
Ni-based superalloy single crystals were grown by different methods (gradient method and Bridgman technique with spontaneous nucleation and with seed). In all crystal growth experiments using the Bridgman technique, the ...
Oxygen reduction at platinum nanoparticles supported on carbon cryogel in alkaline solution
(Srpsko hemijsko društvo, Beograd, 2007)
The oxygen reduction reaction was investigated in 0.1 M NaOH solution, on a porous coated electrode formed of Pt particles supported on carbon cryogel. The Pt/C catalyst was characterized by the X-ray diffraction (XRD), ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder. IV. The internal structure of the powder particles
(Journal of the Serbian Chemical Society, 2004)
The structure of powder particles was analysed by considering their cross sections. It was shown that the structure of powder particles of nonsieved flowing powders is sufficiently dense to produce a continuous surface, ...
The influence of some factors on the electrical conductivity and particle size of core/shell polystyrene/polyaniline composites / Утицај неких фактора на електричну проводљивост и величину честица композита са језгром од полистирена и омотачем од полианилина
(Serbian Chemical Society, 2005)
The electrically conductive, micron-sized, core/shell polystyrene (PS)/polyaniline (PANI) composite particles were synthesized by chemical oxidative polymerization of aniline in the presence of micron-sized PS particles ...
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 ...
