The thermal degradation of some isomers of poly(di-butyl itaconates)
(Elsevier, Amsterdam, 1999)
The non-oxidative and oxidative thermal degradation of poly(di-iso-butyl itaconate) (PDiBI), poly(di-n-butyl itaconate) (PDnBI), and poly(di-sec-butyl itaconate) (PDsBI) were studied by following changes in the polymer ...
EXAFS and XANES study of the incorporation of Mn cations into a chabazite-like AlPO molecular sieve
(Int Union Crystallography, Chester, 1999)
The incorporation of Mn(II) cations into a chabazite-like MnAlPO material is studied with Mn K-edge XANES and EXAFS. Both methods show that Mn(II) is inserted exclusively into the tetrahedrally coordinated aluminum sites. ...
Effect of temperature on surface processes at the Pt(111)-liquid interface: Hydrogen adsorption, oxide formation, and CO oxidation
(Amer Chemical Soc, Washington, 1999)
The variation of the adsorption pseudocapacitance with temperature is used to obtain the enthalpy, entropy, and free energies of adsorption of H-upd and OHad on Pt(lll) as a function of pH and nature of the anion of the ...
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 ...
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 ...
Rheological study of the copolymerization reaction of acrylate-terminated unsaturated copolyesters with styrene
(Wiley-VCH Verlag Gmbh, Weinheim, 1999)
The free radical copolymerization reaction of three series of acrylate-terminated unsaturated polyesters with styrene, using benzoyl peroxide/N,N-dimethylaniline as the redox initiator system, was followed by dynamic ...
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 ...
