The influence of steel surface modification by electrodeposited Zn-Fe alloys on the protective behaviour of an epoxy coating
(Elsevier Science Sa, Lausanne, 2003)
The electrochemical and transport properties of epoxy coatings electrodeposited on steel and steel modified by Zn-Fe alloys were investigated during exposure to 3% NaCl. The Zn-Fe alloys were deposited on steel surface ...
Synthesis and characterization of biodegradable poly(butylene succinate-co-butylene fumarate)s
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
A series of aliphatic biodegradable polyesters modified with fumaric residues was synthesized by transesterification in the melt of dimethyl succinate, dimethyl fumarate and 1,4-butanediol. The amount of unsaturation, ...
Influence of the background electrolyte on the point of zero charge of chromium(III)-oxide
(Trans Tech Publications Ltd, Durnten-Zurich, 2003)
The Point of zero charge of chromium(Ill)-oxide (pH(pzc)) was investigated by a batch equilibration method. The effect of several background electrolytes, in the concentration range of 10(-5)-10(-1) mol/dm(3), on pH(pzc) ...
The combined low-temperature, plasma/enzyme wool shrink-resist treatment
(Amer Assoc Textile Chemists Colorists-Aatcc, Res Triangle Pk, 2003)
To successfully achieve shrink resistance, an enzymatic treatment was applied to knitted fabrics previously treated with a radio-frequency low-temperature plasma. Shrink resistance was attained at the machine-washable level ...
Densities, viscosities, and surface and interfacial tensions of the ternary mixture water plus ethyl butyrate plus methanol at 303.15
(Amer Chemical Soc, Washington, 2003)
The excess molar volumes, V-E, viscosity deviations, Deltaeta, and excess surface tensions were calculated from the measured density, viscosity, and surface tension values, a, over the whole miscibility composition range ...
Surface properties of HAP particles obtained by hydrothermal decomposition of urea and calcium-EDTA chelates
(Proceedings of the 15th International Symposium on Ceramics in Medicine; The Annual Meeting of the International Society for Ceramics in Medicine, 2003)
In this paper surface properties of calcium-hydroxyapatite, synthesized by modified hydrothermal reaction of urea and Ca(EDTA)(2-) in phosphate solutions, as well as the dependence of calcium hydroxyapatite dispersion ...
Kinetic study of methanol oxidation on carbon-supported PtRu electrocatalyst
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
Methanol electrooxidation was investigated on the carbon-supported PtRu electrocatalyst (1:1 atomic ratio) in acid media. X-ray diffraction measurement indicated alloying of Pt and Ru. Cyclic voltammetry of the sample ...
Trace elements analysis of Echinacea purpurea - herbal medicinal
(Elsevier, Amsterdam, 2003)
Elemental composition of Echinacea purpurea (Asteracae), grown in Serbia under strongly controlled conditions, has been studied. To distinguish elemental patterns of different parts of the plant, the content of Zn, Fe, Cu, ...
Recycled-wool-based nonwoven material as a sorbent for lead cations
(Wiley, Hoboken, 2003)
The aim of this study was to investigate the sorption properties of a recycled-wool-based nonwoven material for lead cations. To improve sorption properties, the material was treated with low-temperature air plasma and/or ...
The properties of carbon-supported hydrous ruthenium oxide obtained from RuOxHy sol
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
Preparation of RuOxHy/carbon black nanocomposite material was performed by the impregnation method starting from RuOxHy sol as a precursor. Black Pearls 2000(R) (BP) and Vulcan(R) XC-72 R (XC) were used as supporting ...
