Water plus esters plus methanol: experimental data, correlation and prediction of surface and interfacial tensions at 303.15 K and atmospheric pressure
(Elsevier, Amsterdam, 2004)
For the ternary system water + ethyl propionate + methanol, and the constituent binaries, the surface tension at 303.15 K and atmospheric pressure was measured over the whole miscible composition range. The liquid interfacial ...
Supercritical carbon dioxide extraction of essential oils from plants with secretory ducts: Mathematical modelling on the micro-scale
(Elsevier, Amsterdam, 2007)
In this study, the supercritical carbon dioxide extraction of essential oils from plants which contain secretory ducts as essential oil reservoirs was investigated and modelled. Supercritical carbon dioxide extraction of ...
Electrical properties of cordierite obtained by non-hydrolytic sol-gel method
(Elsevier Sci Ltd, Oxford, 2007)
Cordierite ceramic material, due to its properties such as low thermal expansion coefficient, low dielectric constant and high specific resistivity, could be used as an insulating material in high-frequency electronics. ...
Authors' response to comments on "Factors influencing the removal of divalent cations by hydroxyapatite" Discussion
(Elsevier, Amsterdam, 2009)
Recently. it has come to our attention, that a polemical note by Milonjic [S.K. Milonjic, Comments on "factors influencing the removal of divalent cations by hydroxyapatite", J. Hazard. Mater. 162 (2009) 1588-1589]. has ...
Determination of glass temperature of polymers by inverse gas chromatography
(Elsevier, Amsterdam, 2008)
Inverse gas chromatography (IGC) is an attractive technique for polymer characterization due to possible simultaneous determination of various physicochemical properties of polymer systems merely from retention times of ...
The qualitative electrochemical determination of clarithromycin and spectroscopic detection of its structural changes at gold electrode
(Elsevier Science Inc, New York, 2007)
The aim of the present study was the qualitative determination of the pure clarithromycin using a gold electrode in neutral electrolyte by cyclic linear sweep voltammetry. It was shown that in the range of -1.2 V to 1.0 V ...
Analysis of the effects of catalytic bleaching on cotton
(Springer, Dordrecht, 2007)
Hydrogen peroxide can be catalyzed to bleach cotton fibers at temperatures as low as 30 degrees C by incorporating dinuclear tri-mu-oxo bridged manganese(IV) complex of the ligand 1,4,7-trimethyl-1,4,7-triazacyclononane ...
Dynamic mechanical properties and in vitro bioactivity of PHBHV/HA nanocomposite
(Elsevier Sci Ltd, Oxford, 2007)
Biopolymer composite materials for potential medical applications are of current research interest. In this study, a nanocomposite based on bioresorbable polymer-poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) was ...
A study of the synergistic antilisterial effects of a sub-lethal dose of lactic acid and essential oils from Thymus vulgaris L., Rosmarinus officinalis L. and Origanum vulgare L.
(Elsevier Sci Ltd, Oxford, 2007)
Commercial essential oils of Thymus vulgaris L., Rosmarinus officinalis L. and Origanum vulgare L. were chemically characterized by GC, GC/MS analyses. The antilisterial activity of the oils, and the sub-lethal concentration ...
Influence of thermal treatment on phenolic compounds and antioxidant properties of oak acorns from Serbia
(Elsevier Sci Ltd, Oxford, 2007)
The aim of the present work was to investigate and compare phenolic compounds and antioxidant activity of methanol extracts of Quercus robur and Quercus cerris acorn kernels obtained before and after thermal treatment. ...
