Geometry and energetics of pyridine base adsorption at water-zeolite interfaces: a simulation study

Article Abstract:

Atomic force microscopy has been used to observe the array structures and molecular orientations within liquid-phase-adsorbed pyridine base adlayers on (010) surfaces of the zeolites stilbite and heulandite.

Ab initio and density functional study of the activation barrier for ethane cracking in cluster-models of zeolite H-ZSM-5

Article Abstract:

A new study investigates protolytic cracking of ethane in zeolites, using a cluster model of the zeolite acid site and quantum-chemical techniques.

Determination of extraframework cation positions and their occupancies on heulandite (010) by atomic force microscopy

Article Abstract:

Atoms can be observed and determined for positions on nonconductive surfaces with the advent and progress of atomic force microscopy (AFM) technique. For the first time the array and orientation of the adsorbed molecules on zeolite surfaces could be determined.
