Research subject for a potential FP6 project

As the extensive progress within the Sixth Framework Programme of the European Community for research, technological development and demonstration activities is expected in the field of nanomaterials large effort is to be paid to structural studies performed before, during and after the applied technological operations leading to the desired nano-structures. Here the transmission electron microscopy (TEM) will play a significant role providing large portion of fundamental information.
We have gathered at the IMMM much of experience in preparing samples for TEM observations within the last 20 years. Our preparation techniques based on ion thinning process enable us to prepare TEM samples from various kinds of powders used in powder metallurgy or thermal spraying processes. The technique for TEM cross sectional sample preparation makes us the study of various thin coatings and their interfaces on different substrates possible. Finally microstructure and interfaces in metal matrix composites reinforced with metallic and non-metallic fibers and particles were extensively studied and their structures were revealed.We believe that this know-how and experience can be well integrated in many kinds of projects directed to the development and optimization of nano-structures within the FP6 thematic area.
