Organization of zeolite microcrystals for production of functional materials
Article Abstract:
The methods of organizing zeolite microcrystals into two-dimensional functional entities such as monolayers, multilayers, and patterned monolayers on various substrates and three-dimensional functional entities such as microballs and protein-zeolite composite fibrils are summarized. A brief description of the types of linkages and substrates, degree of coverage, degree of close packing, degree of uniform orientation, and average binding strength between each crystal and substrate is provided.

Selenium/zeolite Y nanocomposites
Article Abstract:
Confinement in molecular sieves is a promising strategy for fabricating nanostructured semiconductor assemblies with a highly uniform size and shape distribution. The way in which the interplay between the confined selenium and extra framework cations in zeolite hosts can be used to tailor properties such as optimized structure, stability, and characteristics and to produce well-defined semiconductor nanocomposites with band gaps in the visible range is discussed.

Nonradical mechanism for methane hydroxylation by iron-oxo complexes
Article Abstract:
Fundamental aspects of methane hydroxylation by Fe[O.sup.+] complex, Fe-ZSM-5 zeolite, and soluble methane monooxygenase (sMMO), were proposed emphasizing mechanistic studies based on quantum chemical calculations. It was concluded that methane hydroxylation could occur in a nonradical, stepwise manner with the bare transition-metal-oxide ions, Fe-ZSM-5 zeolite and sMMO.
