Abstract
The proposed research program is devoted to the development and investigation of modern materials that are applicable in nanotechnology. It is based on a bottom-up approach and focuses on the tailoring of materials from their basic building blocks at the atomic level. The technological potentials of nanotechnology originate in the complexity of the materials involved due to the complicated chemical structure, the reduced dimensionality (thin films, nanowires) and a limited number of building atoms (nanoclusters) Hence, a successful transition to the arena of nanotechnology requires strong and mutually interactive efforts in materials science, chemistry and physics. The activities within the proposed program include experimental and theoretical investigations of the structure, analyses of the chemical composition on the atomic level, measurements and calculations of physical properties as well as the preparation of nanostructured materials. The main focus of the investigations will be the so-called nanostructural elements, namely the structural and chemical elements on the nanolevel that characterize a material - interfaces, planar faults, nanocrystallites, amorphous layers, segregates, etc. The program's aims will be the relations between the nanostructural elements, the material's microstructure and the resulting physical properties. The emphases will be on the following materials: rare-earth-transition-metal intermetallic magnetic materials, natural and synthetic minerals (amorphous and crystalline nanopowders), ceramic sensors, materials for extreme conditions, SiC, Si3N4, varistors, (nano-amorphous layers in polycrystalline ceramics), magnetic thin films, hetero-interfaces for spintronics, ZnO, perovskites and functionally gradient materials. The final aim is to develop the ability to design metallic and ceramic materials with the best properties, either by improving already-investigated or by developing completely new materials.
Significance for science
The importance of the research programme for science can be described in few main contributions. It was not only fully implemented, but also exceeded, due to many new European projects with which we were awarded during the time being of the programme. In the frame of European project ROMEO where one of the main goals is to reduce the usage of expensive heavy-rare-earths (Dy or Tb) in the Nd-Fe-B magnets and at the same time retain or even enhance the magnetic properties, we invented a new processing method which combines electrophoretic deposition and grain boundary diffusion process. The final coercivity was increased for 30 % with ten time’s lower amount of heavy rare earth, which is normally used in practice. Our results achieved a very enthusiastic response from the scientific community in the field. In the frame of the EU’s MNT ERA-Net project (Hy-nano-IM) we developed hydrogen-impermeable coatings for the long-term storage and transport of gaseous and liquid hydrogen. We reported on a permeation reduction factor for hydrogen of up to 20,000 using TiAlN coatings. On EC pages this project was announced as the best MNT ERA-NET project in 2010. A noticeable advance has also been achieved in the development of fusion-relevant material (FP7, EURATOM). A new process “SITE” for the fabrication of ceramic matrix composites has been introduced and has been well recognised internationally. The process paralleled with the Japanese process “NITE” is based on electrophoretic infiltration of the ceramic fabric with ceramic powder, followed by infiltration with sintering aids or a pre-ceramic polymer precursor. In this way the materials properties have closely matched the requirements given by the European Fusion Development Agreement, EFDA. The results have been partially published in J. of Nuclear Materials. We demonstrated the possibility of up-scaling the process and have fabricated a set of samples for mechanical characterisation. We were also strongly involved in the activities of Slovenian Fusion Association and in organizing of Fusion EXPO, a travelling exhibition for fusion promotion In the frame of the project BioTiNet (FP7-ITN) we confirmed excellent photocatalytic activity of the firmly bonded coatings, as well as the UV photo-induced super-hydrophilicity, which appeared also as a prolonged effect (up to two weeks of recovery). The investigations of materials for biomedical application involved preparation and analysis of the scaffolds for hard tissue engineering that is a topic of the COST action NAMABIO. Important research areas of the group is implementation of various electron microscopy analytical techniques within the existing EU project ESTEEM2, such as EELS STEM, HAADF-STEM, electron holography and mechanical preparation of the TEM samples. By the Austrian Society for Electron Microscopy we were awarded for the associated paper with the Fritz Grasenick Award 2012.
Significance for the country
Importance of the research program for Slovenia is on sustaining and improving the quality of life. With the development of environmentally friendly materials and technologies, to substitute for existing ones, we contribute to both a cleaner and a healthier environment. By being increasingly aware of energy saving and environmental problems, we focus on searching for new materials and technologies for saving energy. In the field of high-energy permanent magnets we are involved in four major European projects, two of which we coordinate. Through the partnership in these projects, in which we also included Slovenian industry, we strongly contribute to the successful growth and development of Kolektor Group, Idrija and Magneti Ljubljana. By decreasing the dimensions of the materials that we develop, the surface properties start to prevail and this can be used for detecting small concentrations of agents in the environment, food and body. With the research in the medical use of nanoparticles for targeted drug delivery, we contribute a great deal to a rapidly developing area of science, which is focused on improving the quality of life for cancer patients. The field of materials for biomedical applications is one of the fastest-growing and developing fields in science. The main driving force for this is the growing concern for our health, especially in the older population, for which the injuries to hard tissue are more common. Here we focused our research on the synthesis of scaffolds from a polymeric matrix, reinforced with bioactive-glass nanoparticles. We collaborate with complementary European research groups and the Slovenian company Educell, which gives guidelines to our research together with a COST Namabio action. Our research also contributed in the fields of other nanostructured materials for specific technological applications, such as 1-D nanostructures for humidity, oxygen and UV detection nanosensors. The functional properties of ZnO are used for the application in energy, and the improvement of the quality of life and the environment. In this field we have a long-term and very fruitful collaboration with two industrial partners: Varsi d.o.o. and Iskra Zaščite. The Programme Group “Nanostructured Materials” is strongly linked to many international research networks and in this way contributes to the international recognition of Slovenia. The programme group is also actively involved with undergraduate and graduate students, which is extremely important for broadening the specialization and engineering skills of the next generation. Our outreach activities are strongly demonstrated through popular publications; one of the members of the group successfully introduced and promoted Café Scientific for public called “Science on the street – knowledge and ideas on the go”.
