the main goal of this work was to synthesize and evaluate the effect of dehydration temperature on the potential application of hydroxy sodalite zeolite membrane. hydroxy sodalite zeolite membranes were synthesized via direct hydrothermal method onto a tubular alumina support without seeding in a hot air oven. the synthesized membranes were characterized by x-ray diffraction (xrd) and scanning ...

Faujasite (FAU) zeolites (with Si/Al ratio of ca. 1.7) undergo mild dealumination at moderate ion exchange conditions (0.01 to 0.6 M NH4NO3 solutions) resulting in protons circumscribed by sodalite cages becoming accessible for reaction without conspicuous changes bulk crystallinity. The (HSOD) supercages (HSUP) can be systematically manipulated from 0 1 adjusting ammonium concentrations used e...

Excesses of sulfur-36 in sodalite, a chlorine-rich mineral, in a calcium- and aluminum-rich inclusion from the Ningqiang carbonaceous chondrite linearly correlate with chorine/sulfur ratios, providing direct evidence for the presence of short-lived chlorine-36 (with a half-life of 0.3 million years) in the early solar system. The best inferred (36Cl/35Cl)o ratios of the sodalite are approximate...

Coronene was incorporated into cage-like sodalite-type porous organic salts (s-POSs) which have different degrees of heavy-atom effects depending on the substituents (methyl group and halogens) exposed pore surface. The combination external bromine iodine their oxygen barrier enabled coronene to exhibit room-temperature phosphorescence even in air, with a lifetime more than microseconds. More i...
