Dr. Nina Daneu presented the results of our most recent investigations related to twinning, epitaxies and phase transformations in minerals at the Institute for inorganic chemistry of the Bonn University. The Bonn group is specialized in investigations of atomic structure of nanocrystalline materials, defects in crystals and phase transformations and related mechanisms in solids. Collaboration with the group of prof. Werner Mader is focused especially on the topic of twinning in rutile and epitaxies between minerals with the rutile and corundum-type structures. The collaboration is important for exchange of knowledge and experiences in the field of nanostructural characterisation of different materials and minerals.

COBISS.SI-ID: 25761063Our achievements as well as the general aspects of atomic-scale studies of twinning and phase transformations in minerals were disseminated to international scientific community through invited talks to mineralogical and crystallographic societies. In January 2012, Dr. Aleksander Rečnik was invited to present a talk on 'Nanoscale determination of chemical triggers in minerals' to the Nanomineralogy working group of the Hungarian Academy of Sciences and the Mineralogy-Geochemistry section of the Hungarian Geological Society. The presentation was a boost to strenghten scientific collaboration of our group with Hungarian mineralogists.

COBISS.SI-ID: 25560871The results of our studies in the field pseudomorphic transformations of ilmenite to rutile and hematite on natural samples from Mwinilunga (Zambia) were presented by young researcher Nadežda Stanković at the international scientific conference on materials and technology. The knowledge about this mechanism at the atomic level is important from the basic scientific as well as from technological viewpoint, since the production of rutile from ilmenite ore is constantly growing. Besides, these findings will enable synthesis of complex twinned retiles (fractal structures) for applications in biotechnology. Our analyses on natural samples have revealed these samples are important for learning the basic mechanisms which are further applied for smart synthesis of complex materials (learning from nature).
