Electrical properties of nanoscaled host/guest compounds
Ulrich Simon,Marion E. Franke +1 more
TL;DR: In this paper, the electrical properties of zeolites, molecular and nanoscaled guests in porous solids as well as of microporous semiconductors have been examined by means of impedance spectroscopy or related methods.

Influence of the temperature and water adsorption on the cation location in NaY zeolites
TL;DR: The structures of hydrated and dehydrated NaY zeolites were determined as a function of the temperature, using X-ray powder diffraction methods as mentioned in this paper, and no significant difference was observed between the dehydrated structures, determined at 323 K and at 723 K.

Chapter 8 Metal Clusters and Zeolites
TL;DR: In this paper, the metal reducibility of metal-zeolite combinations is discussed and a wide variety of techniques can be used for the preparation of metal and zerotime combinations, but preparation of a mononodal distribution of metal particle sizes for a given metal and a specific zeolite structure requires specific procedures be followed.

Influence of the temperature on the cation distribution in dehydrated and hydrated SrY zeolites
TL;DR: In this paper, the structures of SrY zeolite were determined in the dehydrated and in the hydrated form by X-ray powder diffractometry and the influence of the temperature on the variation of the cation location was investigated in the range of 323 K to 723 K for hydrated and between 723 and 1123 K for dehydrated forms.

Heat capacities, phase transitions and structural properties of cation-exchanged H-mordenite zeolites
TL;DR: In this article, the authors measured the heat capacity of hydrogen large port mordenite (H-LPM), HLPM+Cu and Na-LMP+Cu samples in the temperature range 25-500°C before and after treatment at 400°C, showing that the changes in the lattice modes were related to the increase in the electrostatic interactions between the cations and the zeolite framework.
