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 ...
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 ...
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 ...
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 ...
Physical-mechanical phenomenon of woven and non-conventional materials
(Emerald Group Publishing Limited, Bradford, 2000)
The basic idea of this project is in developing series of methods for monitoring structural parameters, as well as establishing their relation with the behaviour of woven and non-woven materials. Establishing the connection ...
Deformation pattern and strain hardening in a highly textured 8090 Al-Li alloy sheet
(Elsevier Science Sa, Lausanne, 2000)
Structure-deformation pattern analysis was made on a highly textured 8090 AI-Li alloy sheet deformed in tension. It is shown that the sharp beta-fiber type crystallographic texture induces a strong orientation variation ...
Thermal investigation of two FePO materials prepared in the presence of 1,2-diaminoethane
(Elsevier, Amsterdam, 2000)
Two porous iron phosphates were synthesized hydrothermaly from a reaction mixture of FeCl3:H3PO4:1,2-diaminoethane:H2O in the molar ratio 1:3:5:70. The chemical formulas indicate difference only in water content; however, ...
Influence of different iron powders on the friction properties of sintered friction materials based on iron
(Elsevier Science B.V., 2000)
The possibility of using iron powders of different morphological, chemical and physical properties as the bases of the metal matrix of the friction layer in sintered friction materials for dry friction under severe braking ...
Study of chlorination of nickel silicate by gaseous chlorine and calcium chloride in the presence of active additives
(Wiley, Hoboken, 2000)
The paper presents a thermodynamic analysis and experimental research on the kinetics of the chlorination of nickel silicate (2NiO x SiO2) by gaseous chlorine and calcium chloride without additives and in the presence of ...
Approach to laminar phenomena occurring on external and internal surfaces of solid specimens
(Kluwer Academic Publishers, 2000)
This article presents a general mathematical model for describing the laminar transport phenomena during homogeneous/heterogeneous appearances in the neighborhood of external and internal surfaces of small solid specimens. ...
