Metoda temelji na kompleksnih pojavih, ki se hkrati pojavijo ob uporabi mehanskega stresa, t.j. neelastične deformacije pri kontaktu med različnimi komponentami in s tem povezano medsebojno atomsko izmenjavo ali pa izgubo simetrije osnovnih gradnikov in posledično izmenjavo ligandov. Tovrstni pojavi so še posebej pomembni takrat, ko procesiram eksotične kombinacije, kot so na primer anorganski in organski kristali. V predavanju bodo prikazani številni primeri sinteze nenavadnih koordinacijskih spojin, biokompatibilnih nanokompozitov ter elektrokeramike.<i><span style='mso-fareast-language:ZH-CN'><o:p></o:p></span></i></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt;text-align:justify'>Predavanje bo v angleščini.<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><strong><span style='color:red'>Lepo vabljeni!</span></strong><strong><span style='font-weight:normal'><o:p></o:p></span></strong></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal align=center style='text-align:center'><b><span style='font-size:18.0pt'>***<o:p></o:p></span></b></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal style='text-align:justify'><span lang=EN-US>We would like to invite you to 1th lecture of the "Kolokvij na IJS" in the school year 2011/12.

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.<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><b><span lang=EN-US style='font-size:14.0pt'><o:p> </o:p></span></b></p><p class=MsoNormal><b><span lang=EN-US style='font-size:14.0pt'>We look forward to meeting you at the “Kolokvij na IJS”!<o:p></o:p></span></b></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
