Saturated-liquid heat capacity: New polynomial models and review of the literature experimental data / Toplotni kapacitet zasićene tečnosti - novi polinomski modeli i pregled literaturnih podataka
(Serbian Chemical Society, Belgrade, 2003)
In this paper a review of selected literature experimental data for saturated-liquid heat capacities was presented. Two-, three- and four-parameter polynomial correlation models are tested on those data. Obtained results ...
Gas chromatographic retention indices for N-substituted amino s-triazines on capillary columns - Part IV: Influence of column polarity on retention index / Gasno hromatografski retencioni indeksi N-supstituisanih aminoderivata s-triazina na kapilarnim kolonama - deo IV - uticaj polarnosti kolone na retencioni indeks
(Serbian Chemical Society, Belgrade, 2003)
The retention index increment for the addition of a methylene group to the alkyl group of an analyte molecule is shown to be lower than 100 i.u. for N-substituted amino s-triazines. In temperature programmed gas chromatography, ...
Surface characterization of keratin fibres treated by water vapour plasma
(Wiley, Hoboken, 2003)
The effect of water vapour plasma treatment on the shrinkage behaviour and chemical properties of the surface of keratin fibres was studied. The wettability and shrink resistance of wool were improved even at low plasma ...
Correlation of osmotic coefficient data for ZnSO4(aq) at 25 degrees C by various thermodynamic models
(Kluwer Academic/Plenum Publ, New York, 2003)
The available literature data on the osmotic coefficient of ZnSO4(aq) at 25degreesC in the molality range from 0.1 to 4.3 mol-kg(-1) and new experimental data from 1.2 to 2.9 mol-kg(-1), at the same temperature, are ...
Effects of substituents on the 1H-NMR chemical shifts of 3-methylene-2-substituted-1, 4-pentadienes / Efekti supstituenata na 1H-NMR hemijska pomeranja 3-metilen-2-supstituisanih-1,4-pentadiena
(Serbian Chemical Society, Belgrade, 2003)
The principle of linear free energy relationships was applied to the 1H chemical shifts of the β-vinyl proton atoms of 3-methylene-2-substituted-1,4-pentadienes. The correlations of the proton chemical shifts with Swain ...
The kinetics of the reactions of 2-substituted nicotinic acids with diazodiphenylmethane in various alcohols / Kinetika reakcija 2-supstituisanih nikotinskih kiselina sa diazodifenilmetanom u različitim alkoholima
(Serbian Chemical Society, Belgrade, 2003)
The rate constants of 2-substituted nicotinic acids in reaction with diazodiphenylmethane (DDM) in eight alcohols at 30 ºC have been determined. In order to explain the obtained results through solvent effects, the second ...
Influence of the mobile-phase modifier on the retention of some para-substituted amides; Correlation with compound lipophilicity
(Springer Heidelberg, Heidelberg, 2003)
The chromatographic behavior of Para-substituted amides of alpha-phenylacetic, benzoic, propanoic, and 2,2-dimethylpropanoic acid has been studied in reversed-phase thin-layer chromatography on silica gel impregnated with ...
Kinetics of the zinc anodic dissolution reaction in near neutral EDTA solutions / Kinetika anodnog rastvaranja cinka u blisko neutralnim rastvorima EDTA
(Serbian Chemical Society, Belgrade, 2003)
Polarization curves of the anodic dissolution reaction of zinc were determined in EDTA solutions of different total molar concentrations (0.05 0.10, 0.15 and 0.20 mol dm-3), the pH values of which were systematically varied ...
Synthesis and investigation of solvent effects on the ultraviolet absorption spectra of 1, 3-bis-substituted-5, 5-dimethylhydantoins / Sinteza i ispitivanje efekata rastvarača na UV spektre 1,3-bis-supstituisanih-5,5-dimetilhidantoina
(Serbian Chemical Society, Belgrade, 2003)
A series of 1,3-bis-substituted-5,5-dimethylhydantoins was synthesized using the reaction of 5,5-dimethylhydantoin with the corresponding alkyl halide in the presence of trimethylamine as catalyst and sodium hydroxide, ...
The role of the concentration profile of titanium oxide on the electrochemical behavior of RuO2-TiO2 coatings obtained by the sol-gel procedure / Uloga koncentracionog profila titan-oksida u elektrohemijskom ponašanju RuO2-TiO2 prevlaka dobijenih sol-gel postupkom
(Serbian Chemical Society, Belgrade, 2003)
In order to understand the role of TiO2 in the deactivation mechanism of an active RuO2–TiO2 coating, an additional TiO2 layer was introduced in the support coating interphase of regular Ti//[RuO2–TiO2 anode in one case ...
