Mechanochemical synthesis and electrical conductivity of nanocrystalline δ-Bi2O3 stabilized by HfO2 and ZrO2
(Belgrade : Serbian Chemical Society, 2009)
A powder mixture of α-Bi2O3 and HfO2, in the molar ratio 2:3, was mechanochemically treated in a planetary ball mill under air, using zirconium oxide vials and balls as the milling medium. After 50 h of milling, 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 ...
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, ...
The study of linear solvation energy relationship for the reactivity of carboxylic acids with diazodiphenylmethane in protic and aprotic solvents / Proučavanje reaktivnosti karboksilnih kiselina sa diazodifenilmetanom u aprotičnim i protičnim rastvaračima pomoću linearne korelacije solvatacionih energija
(Serbian Chemical Society, Belgrade, 2009)
Solvent effects on the reactivity of cycloalkenecarboxylic, cycloalkeneacetic, 2-substituted cyclohex-1-enecarboxylic, 2-substituted benzoic, 2-substituted cyclohex-1-eneacetic, 2-substituted phenylacetic, 2-phenylcycloh ...
A study of the electrochemical behavior of methomyl on a gold electrode in a neutral electrolyte / Proučavanje elektrohemijskog ponašanja metomila na elektrodi od zlata u neutralnom elektrolitu
(Serbian Chemical Society, Belgrade, 2009)
A gold electrode was used for the qualitative and quantitative electrochemical determination of analytical methomyl in a neutral electrolyte (0.050 M NaHCO3) using cyclic linear sweep voltammetry. In the potential range ...
Densities and excess molar volumes of alcohol + cyclohexylamine mixtures / Gustine i dopunske molarne zapremine smeša alkohol + cikloheksilamin
(Serbian Chemical Society, Belgrade, 2009)
Densities of binary mixtures of 1-propanol, or 2-butanol, or 1-pentanol + cyclohexylamine were measured at temperatures from 288.15 to 313.15 K and atmospheric pressure, while the densities for the system 2-methyl-2-propanol ...
Molecular interaction studies of the volumetric behavior of binary liquid mixtures containing alcohols / Studija molekulskih interakcija na bazi volumetrijskih svojstava tečnih binarnih smeša koje sadrže alkohole
(Serbian Chemical Society, Belgrade, 2009)
An attempt has been made to relate the volumetric effects involved in the binary mixtures of normal and branched alcohols and various components (aromatics, halo and nitroaromatics and haloaliphatics) with the molecular ...
Effects of solvent and structure on the reactivity of 6-substituted nicotinic acids with diazodiphenylmethane in aprotic solvents / Uticaj rastvarača i strukture na reaktivnost 6-supstituisanih nikotinskih kiselina sa diazodifenilmetanom u aprotičnim rastvaračima
(Serbian Chemical Society, Belgrade, 2009)
The rate constants for the reactions of diazodiphenylmethane (DDM) with 6-substituted nicotinic acids in aprotic solvents at 30°C were determined. The obtained second order rate constants in aprotic solvents, together with ...
