Properties of aliphatic hyperbranched polyesters in dilute solutions
(Serbian Chemical Society, 2007)
The results of an investigation of the influence of the synthesis procedure, number of pseudo generations and degree of branching of hydroxy-functional aliphatic hyperbranched polyesters (AHBP) on the values of limiting ...
Relationship between the kinetic parameters and morphology of electrochemically deposited lead
(Serbian Chemical Society, 2016)
The processes of lead electrodeposition from electrolytes of various concentrations of sodium nitrate as the supporting electrolyte have been examined by chronoamperometry and by the scanning electron microscopic (SEM) ...
Reactivity of cyclohex-1-enylcarboxylic and 2-methylcyclohex-1-enylcarboxylic acids with diazodiphenylmethane in aprotic solvents / Reaktivnost cikloheks-1-enilkarbonske i 2-metilcikloheks-1-enilkarbonske kiseline sa diazodifenilmetanom u aprotičnim rastvaračima
(Serbian Chemical Society, Belgrade, 2000)
Rate constants for the reaction of diazodiphenylmethane with cyclohex-1-enylcarboxylic acid and 2-methylcyclohex-1-enylcarboxylic acid were determined in nine aprotic solvents, as well as in seven protic solvents, at 30 ...
The current distribution in an electrochemical cell. Part VII. Concuding remarks
(Serbian Chemical Society, 2002)
A new method for the determination of the ability of an electrolyte to distrubute uniformly current density in an electrochemical cell is proposed. It is based on the comparison of the current in cells in which the electrode ...
A mathematical model of the current density distribution in electrochemical cells / Matematički model raspodele gustine struje u elektrohemijskim ćelijama
(Serbian Chemical Society, 2011)
An approach based on the equations of electrochemical kinetics for the estimation of the current density distribution in electrochemical cells is presented. This approach was employed for a theoretical explanation of the ...
A novel platinum-based nanocatalyst at a niobia-doped titania support for the hydrogen oxidation reaction
(Journal of the Serbian Chemical Society, 2011)
The kinetics of the hydrogen oxidation reaction (HOR) was studied at Pt nanoparticles supported on niobia-doped titania (Pt/N-T). The catalyst support, with the composition of 0.05NbO(2.5-delta)-0.995TiO(2) (0 LT delta LT ...
Tailoring the supercapacitive performances of noble metal oxides, porous carbons and their composites / Rasvetljavanje superkondenzatorskih odlika oksida plemenitih metala, poroznih ugljeničnih materijala i njihovih kompozita
(Serbian Chemical Society, 2013)
Porous electrochemical supercapacitive materials, as an important type of new-generation energy storage devices, require detailed analysis and knowledge of their capacitive performances under different charging/discharging ...
Biodegradation of starch-graft-polystyrene and starch-graft-poly(methacrylic acid) copolymers in model river water / Biodegradacija kalemljenih kopolimera skroba i polistirena i skroba i poli(metakrilne kiseline) u rečnoj vodi
(Serbian Chemical Soc, Belgrade, 2013)
In this paper, a biodegradation study of grafted copolymers of cornstarch and polystyrene (PS) and cornstarch and poly(methacrylic acid) in model river water is described. These copolymers were obtained in the presence of ...
Solvent effect on electronic absorption spectra of cyclohex-1-enylcarboxylic and 2-methylcyclohex-1-enylcarboxylic acids / Efekti rastvarača na elektronske apsorpcione spektre cikloheks-1-enilkarbonske i 2-metilcikloheks-1-enilkarbonske kiseline
(Serbian Chemical Society, Belgrade, 2000)
The ultraviolet absorption spectra of cyclohex-1-enylcarboxylic acid and 2-methylcyclohex-1-enylcarboxylic acid were determined in six protic and nine aprotic solvents in the wavelength range from 200 to 400 nm. The position ...
