ZeoliteWikipedia
Zeolites are microporous aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt who observed that rapidly heating the material believed to have been stilbite produced large amounts of steam from water that had been adsorbed by the material.

Thermodynamics of quantum fluids confined in zeolites at
The thermal properties of quantum fluids at low temperature (T) are determined by the spectrum of excitations which possess the lowest frequencies. In the case of a fluid such as helium or hydrogen confined in a one-dimensional (1D) pore these excitations are phonons with wave vector parallel to the pore s axis. This paper describes the consequences of this fluid s confinement for the low-T
