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, ...
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 ...
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 ...
Estimate of Si3N4 diffusion into Cu based filler metal
(Elsevier Science Ltd, 2000)
The diffusion phenomena occurring at the boundary between Si3N4 and active Cu based filler metal during Si3Nn/metal joining are discussed as a part of the general theory of reaction layer growth. The mechanism of reaction ...
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 ...
Volcano plots along intermetallic hypo-hyper-d-electronic phase diagrams and electrocatalysis for hydrogen electrode reactions
(Journal of New Materials for Electrochemical Systems, 2000)
The nature, causes and consequences of the existence of volcano plots along transition series with resulting theoretical conclusions have been extended on the Brewer hypo-hyper-d-electronic combinations of transition metal ...
An analytical 3-D model for small dimensions MOSFETs' threshold voltage
(2000 22nd International Conference on Microelectronics, MIEL 2000, 2000)
This paper has presented an analytical three-dimensional (3D) model for threshold voltage of small dimensions MOSFETs with an experimental dependence of acceptor concentration in the channel. The corresponding algorithms ...
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 ...
Electrochemical studies on LaNi4.15Co0.43Mn0.40Fe0.02 metal hydride alloy
(Elsevier Science Sa, Lausanne, 2000)
Electrochemical studies were performed on LaNi4.15Co0.43Mn0.40Fe0.02. alloy electrode. The kinetics of the electrochemical hydrogen absorption/desorption reaction was studied by DC polarization and AC impedance measurements. ...
Formic acid oxidation on pure and Bi-modified Pt(111): Temperature effects
(Amer Chemical Soc, Washington, 2000)
Temperature effects on the kinetics of formic acid electrooxidation are studied on Pt(111) and on Pt(111) modified by irreversibly adsorbed Bi under both potentiodynamic and potentiostatic conditions. We propose two modes ...
