The effect of the size and shape of alumina nanofillers on the mechanical behavior of PMMA matrix composites
(Srpsko hemijsko društvo, Beograd, 2014)
Composites with the addition of alumina nanofillers show improvement in mechanical properties.Poly(methyl methacrylate), PMMA, was used as a matrix and two different types of nanofillers having extremely different shapes ...
The application of NIR spectroscopy with chemometric analysis for monitoring a powder blending process
(Srpsko hemijsko društvo, Beograd, 2014)
This paper reports the use of near infrared (NIR) spectroscopy as a process analytical technology (PAT) tool for monitoring the metformin (N,N-dimethylimidodicarbonimidic diamide) hydrochloride and poly(vinyl pyrrolidone) ...
Aqueous nicotine solutions: pH-measurements and salting-out effects - Analysis of the effective Gibbs energies of hydration and ionic strengths of the solutions
(Srpsko hemijsko društvo, Beograd, 2014)
This work is a continuation of previous studies on phase demixing - salting-out effects in aqueous nicotine solutions. Thus, pH measurements were performed, allowing a brief analysis of the existing hydrogen bond interactions. ...
Prediction of excess molar volumes of selected binary mixtures from refractive index data
(Srpsko hemijsko društvo, Beograd, 2014)
The excess molar volumes of twenty two binary mixtures containing various groups of organic compounds: alcohols (ethanol, 1-propanol, 1,2-propanediol, 1,3-propanediol and glycerol), ketone (acetone), ester (butyl lactate), ...
Densities, refractive indices and viscosities of the binary mixtures of dimethyl phthalate or dimethyl adipate with tetrahydrofuran
(Srpsko hemijsko društvo, Beograd, 2014)
Densities, refractive indices and viscosities of the binary mixtures of dimethyl phthalate (or dimethyl adipate) + tetrahydrofuran have been measured at eight temperatures (288.15 to 323.15 K) and atmospheric pressure. All ...
Synthesis, characterization and crystal structure of Cu(II) complex with a diimine-dioxime ligand, [Cu-2(LH)(2)](ClO4)(2). Influence of the weak Cu center dot center dot center dot O(perchlorate) interaction on the structure of the Cu2N2O2 metallocycle
(Srpsko hemijsko društvo, Beograd, 2014)
The diimine dioxime ligand, 3,3'-(1,4-butanediyl-dinitrilo)bis-2-pentanone, 2,2'-dioxime (LH2), containing a N-4 donor set was prepared by the Schiff base condensation of 2-hydroxyimino-3-pentanone and 1,4-diaminobutane ...
Optimization of electrochemical decolorization of certain arylazo pyridone dyes
(Srpsko hemijsko društvo, Beograd, 2014)
Electrocatalytic decolorization of arylazo pyridone dyes was investigated in the presence of sodium chloride using a DSA Ti/PtOx electrode in dilute sodium hydroxide. The decolorization could be attributed to the indirect ...
Liquid mixture viscosities correlation with rational models
(Srpsko hemijsko društvo, Beograd, 2014)
In this paper, twenty two selected rational correlation models for the viscosities of liquid mixtures of organic compounds were tested on 219 binary sets of experimental data taken from the literature. The binary sets ...
A microwave approach to the synthesis of certain 4-(substituted phenyl)-6-phenyl-3-cyano-2-pyridones
