The development of new materials and nanotechnologies profoundly influences the quality of our lives in modern societies. Research activities directed towards these areas have become popular scientific fields in the technologically developed parts of the world. One of the main goals is to improve the materials` properties, which will result in new applications, the miniaturisation of existing systems, improved energy-conversion efficiencies and the development of environmentally friendly technologies. These goals are also reflected in the scope of the research activities of the Advanced Materials Group that operates in the frame of the Jožef Stefan Institute.

The basic research hypothesis of the group is that the phase composition, the crystal structure, the microstructure and the morphology of materials with a certain chemical composition crucially influence number of properties. The research activities of the group thus encompass studies of phase relations within multi-component systems, the determination of crystal structures and defects, studies of the mechanisms and kinetics of the chemical reactions that take place during the synthesis, studies of the phase transformations and studies of the microstructure development of polycrystalline materials, as well as the morphology development of nanostructured materials. The main goals are exposing the relations between these parameters and the resulting properties of the materials and the development of new synthesis methods that could lead to new functional properties and consequently to the development of new applications.

The goals of our work are to acquire original scientific knowledge that will enable the synthesis of new materials with improved electrical properties and to acquire knowledge that will enable the preparation of the selected materials in the form of nanostructures. These research activities are thus focused on a determination of the basic characteristics, while some of the fields mentioned also relate to applied research, which is connected with industrial partners across Europe.

A number of other activities in the field of applied research, which is based on collaborations with domestic and international research groups and industrial partners, prove that applicable solutions are of significant importance for the group. Some of these activities are:

  • the development of materials for multilayered electronic components (ceramics capacitors, piezoactuators, varistors, etc),
  • the development of super hard materials,
  • the development of self-cleaning and anti-bacterial layers for household appliances,
  • the development of mineral fibres for sound and heat isolation,
  • the development of glassy materials.
