New aspects of processing nanomaterials under mechanical stressing

This video was recorded at Kolokviji na Institutu "Jožef Stefan". Can a brutal force bring us anything positive? Definitely not. This is also the case in the nanocomposite materials in every genre. Exertion of mechanical stressing on the fine powdered mixtures, however, brings us fascinating states toward functional composites or compounds, which no other methods can realize, when carried out carefully and under a solid guiding principle. This is based on the complex phenomena occurring simultaneously, e.g. shear stress and consequent non-elastic deformation at the contact of dissimilar partners and associated mutual atomic penetration called mechanical diffusion, symmetry loss of the solid construction units (e.g. metal-O6 octahedra for many transition metal oxides) and consequent ligand exchange, etc. This is particularly significant, when we observe the exotic combinations, notably those of inorganic and organic crystals. Case studies will cover syntheses of some unusual coordination compounds, biocompatible nanocomposites and electroceramics for microdevices.
