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 ...
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 ...
Synthesis of nanostructured boehmite powder by sol-gel method from industrial Na-aluminate solution
(Techna Srl, Faenza, 2003)
Supersaturated Na-aluminate solution from KAP's Alumina plant Bayer process was chosen, as a precursor to synthesize low sodium content nanostructured boehmite powder. Firstly, the solution, was neutralized with strong ...
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 ...
Substituent and solvent effects on the UV/vis absorption spectra of 3-N-alkyl-5-carboxy uracils
(Natl Inst Science Communication, New Delhi, 2003)
Absorption spectra of ten 3-N-alkyl-5-carboxy uracils are recorded in fourteen solvents in the range 200-400 nm. The absorption frequencies of carboxy carbonyl electronic transitions are correlated by dual substituent ...
Examination of rheological properties of fine particles as carriers for controlled drug release
(Taylor & Francis Inc, Philadelphia, 2003)
Development of lipid-based fine particles as potential drug carriers requires detailed investigation of possible effects of these carriers on rheological properties of blood. In this study, we have investigated the influence ...
Biomarkers of oil-type pollutants in surface soil
(Parlar Scientific Publications (P S P), Freising, 2003)
In this paper, biomarkers were applied for identification of oil-type pollutants in surface soil and their microbial changes were investigated. Samples were taken at destroyed fuel storage in Nis (Yugoslavia). Steranes, ...
