Synthesis of nanostructured mullite from xerogel and aerogel obtained by the nonhydrolytic sol-gel method
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
Synthesis and nanostructure evolution of mullite (3Al(2)O(3).2SiO(2)) from xero- and aerogels, obtained by the non-hydrolytic sol-gel process are described. Mullite crystallization and gel nanostructure evolution after ...
Reactivity of beta-aroylacrylic acids with diazodiphenylmethane (vol 63, pg 359, 1998)
(Srpsko hemijsko društvo, Beograd, 1999)
Corrosion protection of aluminium by a cataphoretic epoxy coating
(Elsevier Science Sa, Lausanne, 1999)
The corrosion behavior and thermal stability of epoxy coating electrodeposited on aluminium have been investigated during exposure to 3% NaCl. Electrochemical impedance spectroscopy (EIS), gravimetric liquid sorption ...
A study of the tetrahallogenonickel(II) complexes by the Fenske-Hall molecular orbital method
(Society of Chemists and Technologists of Macedonia, 1995)
The coordination geometry and electronic structure of the NiX4(2-) complex ions (X=Cl, Br, I) have been studied by the Fenske-Hall SCF method. The calculation confirm the presence of tetrahedral over square-planar geometry. ...
Glycidyl esters synthesis catalysed by ion-exchange resins
(Serbian Chemical Society, Belgrade, 1996)
Ion-exchange resins not previously used for this purpose were employed to study the synthesis of glycidyl esters. The reaction was carried out both with free acids and their sodium salts. The model reaction was the synthesis ...
Cobalt(II)-exchange in Zeolite A
(Akadémiai Kiadó, 1995)
The influence of the initial Co(2+) and Na(+) concentrations (Co(Co) and Co(Na), respectively) upon the exchange degree (y) of Na(+) by Co(2+) ions in Zeolite A at 20 oC has been studied. The observed increase of y with ...
The determination of kinetics parameters of the hydrogen evolution on Ti-Ni alloys by ac impedance
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The kinetics and mechanism of hydrogen evolution at Ti-Ni alloys electrode has been studied by means of steady-state potentiostatic polarization and ac impedance spectrum measurements. Complex-plane spectrum plots are ...
Formability of a high-strength Al Mg6.8 type alloy sheet
(Springer, New York, 1998)
Room temperature formability testing was performed on an AlMg6.8 type alloy sheet with a fully recrystallized structure (average grain diameter similar to 18 mu m) and after partial annealing with a retained deformed ...
A novel triclinically deformed chabazite-like aluminophosphate prepared in the presence of tris(1,2-diaminoethane)nickel(II) chloride
(Elsevier, 1998)
The tris(1,2-diaminoethane)nickel(II) complex was found to be a novel structure-directing agent for the preparation of the chabazite-like AlPO4-34 molecular sieve. During crystallization the complex undergoes a ligand ...
Isomorphous element substitution in the chabazite-like aluminophosphate framework
(Akademiai Kiado Zrt, Budapest, 1998)
Thermal investigations and Fenske-Hall SCF MO calculations have been used for studying isomorphous element substitution in the chabazite-like aluminophosphate framework prepared in the presence of tetraethylammonium hydroxide ...
