The results obtained and consequently the evaluations and conclusions from a 5-year research program have enabled the possibilities of answering specific questions that emerged within the scope of this program. We succeeded in clarifying the specific aspects of the starting gels, established optimal synthesis conditions and parameters for a specific type of material and evaluated their influence on the type, nature, properties and specific details of various novel materials. Structural identification and characterization, particularly with regard to amounts of framework-substituted metals, have helped in the classification of these materials not only from a physico-chemical point of view but also from their potential, usually specific use(s). The results from the program represent new contributions to the field of syntheses and characterizations of novel micro- and mesoporous crystalline zeolite analogs and a new knowledge has been acquired regarding the optimization of conditions for a successful modifications of frameworks with metal atoms. Framework modifications were carried out only with those atoms that exhibited redox- and catalytic properties that have been in most cases connected to changes in the oxidation number of metal atoms. Reactions, catalyzed by these materials, take place under environmental-friendly conditions and yield high degrees of conversions. The use of previously characterized nanocomposites can be anticipated in the area of electrochemical sensors for the determination of environmental and agricultural pollutants. Important aspect of the results obtained are their publication and dissemination within international scientific community and the collaboration with international research groups which has always been maintained intensively. Particular attention has been devoted to projects within appropriate programs of the EU (we cooperate in the 6th framework program: Network of excellence --INSIDE-PORES).
