Corrosion behaviour of epoxy coatings electrodeposited on galvanized steel and steel modified by Zn-Ni alloys
(Elsevier Science Sa, Lausanne, 2000)
The electrochemical and transport properties and thermal stability of epoxy coatings electrodeposited on hot-dip galvanized steel and steel modified by Zn-Ni alloys were investigated during exposure to 3% NaCl solution. ...
A new approach to the velocity field investigation in case of the entry flow in curved pipes with circular cross section
(Springer Wien, Wien, 2000)
In this paper an analysis of a laminar flow in a bend preceded by the straight section is presented. The flow is supposed to be unperturbed far upstream, while far downstream it becomes fully developed. In the vicinity of ...
Mixed ligand Co(II), Ni(II) and Cu(II) complexes containing terephthalato ligands. Crystal structures of diaqua(2,2 '-dipyridylamine)(terephthalato)metal(II) trihydrates (metal = cobalt or nickel)
(Pergamon-Elsevier Science Ltd, Oxford, 2000)
A series of nine ternary Co(II), Ni(II) and Cu(II) complexes with some aromatic diamines and dianion of terephthalic acid (tpht) have been synthesized and characterized by elemental analysis, magnetic susceptibility ...
The thermal degradation of poly(di-n-propyl itaconate) and poly(di-iso-propyl itaconate)
(Elsevier Sci Ltd, Oxford, 2000)
The non-oxidative thermal degradation mechanism of poly(di-n-propyl-) (PDnPI) and poly(di-iso-propyl itaconate) (PDnPI) were investigated and compared to the structurally similar polymethacrylates. Analogous to the ...
Stability of chromium(III)-oxide sol in the presence of inorganic anions
(Trans Tech Publications Ltd, Durnten-Zurich, 2000)
Stability of chromium(III)-oxide sol upon the addition of various electrolytes (chloride, sulfate, and ferrocyanate) was studied by a potentiometric titration method. The critical coagulation concentration was determined ...
Immobilization/encapsulation of cells using electrostatic droplet generation - Experiments and theory
(Minerva Biotecnologica, 2000)
The mechanism of alginate droplet formation as well as experimental parameters for producing very small polymer microbeads (i,e, less then 100 microns diameter) using an electrostatic droplet generator were investigated, ...
Influence of formation conditions and precursor viscosity on mean fiber diameter formed using the relating disk method
(Elsevier, Amsterdam, 2000)
Alumina ceramic fibers were produced from aluminum-hydroxidechloride based sol. Polyvinyl alcohol and surface active material were applied to adjust the rheological characteristics of the: sol. The rotating disk formation ...
Bi adsorption on Pt(111) in perchloric acid solution: A rotating ring-disk electrode and XPS study
(Royal Soc Chemistry, Cambridge, 2000)
The surface electrochemistry of reversibly and irreversibly adsorbed bismuth (Bi-ad) was studied on Pt(111) electrodes in 0.1 M HClO4. The valence state of irreversibly adsorbed Bi (Bi-ir) was determined by ex situ X-ray ...
Structural effects during CO adsorption on Pt-bimetallic surfaces I. The Pt(100) electrode
(Elsevier, Amsterdam, 2000)
Synchrotron surface X-ray scattering (SXS) and rotating ring disk electrode (RRDE) measurements have been performed during the coadsorption of metal adatoms and carbon monoxide on the Pt(100) surface in an electrochemical ...
Study of chlorination of nickel ferrite by gaseous chlorine and calcium chloride in the presence of active additives
(Wiley, Hoboken, 2000)
Thermodynamic analysis and experimental research of the chlorination of nickel ferrite (NiFe2O4) by gaseous chlorine in the presence of added C, BaS, S and NaCl in the temperature range from 300 to 900 degrees C are given ...
