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...

Recently, LTA-Se(1–8) samples with 1–8 Se atoms per cavity (simplified unit cell, large + sodalite cage) obtained via adsorption at the temperature of ∼450 °C were reported. It was shown that single Se8 or Se12 ring are formed in LTA cavities, Se8/Se12 concentration ratio decreasing an increase loading density. Contrary, present work, using vapour ∼550 °C, we succeeded encapsulation ∼17 (LTA-Se...
