Tubular MFI Zeolite Membranes Made by In-Situ Crystallization
Polycrystalline MFI zeolite membranes were prepared on α-alumina tubular support by hydrothermal treatments at 413 K. The synthesized zeolite membranes were characterized by XRD, SEM and single gas permeation. The influence of hydrothermal treatment steps and the calcination time on the zeolite layer formation were investigated. MFI zeolite membrane prepared by four subsequent hydrothermal ...
متن کاملIn situ pressure crystallization: an alternative to crystallization by cooling
Acta Crystallographica Section A: Foundations and Advances publishes articles reporting fundamental advances in all areas of crystallography in the broadest sense. This includes metacrystals such as photonic or phononic crystals, i.e. structures on the mesoor macroscale that can be studied with crystallographic methods. The central themes are, on the one hand, experimental and theoretical studi...
متن کاملCrystallization Behavior and Mechanical Properties of In-situ Alumina-Zirconia Composite Bodies
In-situ alumina-zirconia composite bodies were fabricated by heat treatment of gibbsite-zircon-kaolinite mixture at 1450℃. The current research investigated crystallization behavior and mechanical properties of the mentioned mixture in the presence of 5 wt.% MgO as an additive. X-ray diffraction (XRD) results showed that alumina, zirconia, and magnesium aluminosilicate were crystallized during ...

متن کاملObserving "Man" in Situ: Edward Burnett Taylor's Travels Through Mexico
In the spring of 1856, I met Mr. Christy accidentally in an omnibus at Havana. He had been in Cuba for some months, leading an adventurous life… and visiting all sorts of people from whom information was to be had.
