Researchers' Proposals
Preparation of self-assembled mono-layers on modified gold and on iron surfaces. In situ investigation of morphological properties by using electrochemical scanning probe microscopy on polycrystalline and mono-crystalline surfaces.
Investigation of the kinetics of the formation of mono-layers by using electrochemical quartz micro-balance techniques.
Surface modification will be carried out by wet chemical (Langmuir-Blodgett, self-assembling) and electrochemical (pulse and under-potential metal deposition) techniques in order to functionalise surfaces for nano-technology and for elaboration of special sensors, electro-catalysts and catalysts. Investigations are and will be conducted and deepened in the poorly explored field of surface transformations initiated by high-energy particle beams and in high temperature plasma environment. The approach of surface engineering and complex characterisation of composition, chemical structure and bonding, morphology and performance of the modified surface is going to be investigated.
Nanostructures
Investigation of new nanostructures (biopolymers, coatings, nanotubes, Langmuir-Blodgett layers, etc.) Nanotubes are promising materials due to their high tensile strength and a possible catalyst support, especially if the catalytic metal nano-particles can be introduced into the nanotubes. A primary objective of study of preparation and application of nanotubes is to exploit and implement their use in various areas of industrial applications.
Materials research
Development of tailor made synthesis of nano-porous materials and their use in catalysis in working contact with researchers of European Community and Zeolite Association. Among nanostructured materials a special attention has to be paid to catalysts because of their vast industrial importance. Upon raising the integrated approach of nano-technology and other methods for catalyst preparation, the productivity of catalysis research can be increased resulting in highly selective catalysts for better and cleaner processes, promoting environmental protection, safety and improving by this way the quality of life.
Understanding fundamental processes of corrosion considerably can contribute to the development of real solutions to the problems of engineering associated corrosion inhibition. Use of high-level scientific knowledge of corrosion and corrosion inhibition at nano- and micro-scale provides multi-faced, interactive solutions to different problems.

One main research interest is to produce nanocrystalline metal and alloy coatings, as well as foils without porosity by application pulse electrochemical technique. The final goal is to develop a precise process for deposition of pure Ni, Fe layers and Zn-Ni nanostructured coatings. The novel products find utility as corrosion resistant coatings, catalysts for alcohol oxidation in aqueous, solution and as a magnetic materials.
It is planned to syntetize multilayered magnetic structures with ultrafine alternating magnetic and non-magnetic ( Fe/Cu ) multilayers and prepare nanocrystaline metal oxides using electrochemical methods.
