Application of modern technology in the production of paper for saving energy
(Editura Acad Romane, Bucuresti, 1998)
All researches conducted with the objective of energy savings in paper industry point out that today in Yugoslavia and South East Europe this industrial branch consumes 30-40% more specific energy than Western Europe. The ...
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 ...
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 ...
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 ...
