Mednje spadajo kontaktni, ciklični in interpenetracijski dvojčki ter epitaksialna preraščanja strukturno sorodnih faz. V predavanju bom na različnih primerih pokazala, da je poznavanje lokalne atomske strukture in kemijske sestave kontaktnih ravnin med kristalnimi domenami, ki se med rastjo povežejo preko določenega kristalografskega zakona, ključno za razumevanje njihovega nastanka. Glavno eksperimentalno orodje za naše analize je presevna elektronska mikroskopija. Rezultati raziskav po eni strani omogočajo interpretacijo geokemijskih pogojev med rastjo mineralov v naravi, po drugi strani pa lahko spoznanja, pridobljena pri proučevanju naravnih mineralov, s pridom uporabimo za sintezo funkcionalnih materialov z izboljšanimi lastnostmi.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><b><span lang=EN-US>O predavateljici</span></b><span lang=EN-US>: Nina Daneu je znanstvena svetnica na Institutu »Jožef Stefan« in izredna profesorica na Mednarodni podiplomski šoli Jožefa Stefana v Ljubljani.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt'>Napovednik predavanja in posnetke preteklih predavanj najdete na <b>novi spletni strani »Kolokvijev na IJS«</b> </span><span lang=EN-US><a href="https://kolokviji.ijs.si/"><span style='font-size:10.0pt'>https://kolokviji.ijs.si/</span></a></span><span lang=EN-US style='font-size:10.0pt'>, posnetke pa tudi posebej na </span><span lang=EN-US><a href="https://video.arnes.si/?q=Kolokviji_IJS"><span style='font-size:10.0pt'>https://video.arnes.si/?q=Kolokviji_IJS</span></a></span><span lang=EN-US style='font-size:10.0pt'> (zadnje tri sezone) in </span><span lang=EN-US><a href="http://videolectures.net/kolokviji_ijs"><span style='font-size:10.0pt'>http://videolectures.net/kolokviji_ijs</span></a></span><span lang=EN-US style='font-size:10.0pt'> (starejši).<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>______________<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>We invite you to the 10th lecture in the framework of »JSI Colloquia« in the academic year 2024/25, which will take place on <b>Wednesday, April 23, 2025, at 1:00 PM</b> in the main lecture hall of Jožef Stefan Institute, Jamova cesta 39 in Ljubljana.

Examples include contact, cyclic, and interpenetration twins, as well as epitaxial intergrowths of structurally related phases. In my lecture, I will present various examples to show that the knowledge of the local atomic structure and chemical composition of crystallographic interfaces that form during crystal growth is key to understanding their formation. The main experimental tool for our analyses is transmission electron microscopy. The results of our research enable, on the one hand, the interpretation of geochemical conditions during mineral growth in nature, and on the other hand, the application of insights gained from natural minerals to the synthesis of functional materials with improved properties.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><b><span lang=EN-US>About the lecturer</span></b><span lang=EN-US>: Nina Daneu is a scientific councilor at the Jožef Stefan Institute and an associate professor at the Jožef Stefan International Postgraduate School in Ljubljana.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoPlainText><span lang=EN-US style='font-size:10.0pt'>The lecture trailer and recordings of past lectures can be found on the <b>new website of »JSI colloquia«</b></span><span lang=EN-US> <a href="https://kolokviji.ijs.si/"><span style='font-size:10.0pt'>https://kolokviji.ijs.si/</span></a></span><span lang=EN-US style='font-size:10.0pt'>, and recordings specifically at </span><span lang=EN-US><a href="https://video.arnes.si/en/?q=Kolokviji_IJS"><span style='font-size:10.0pt'>https://video.arnes.si/en/?q=Kolokviji_IJS</span></a></span><span lang=EN-US style='font-size:10.0pt'> (last three seasons) and </span><span lang=EN-US><a href="http://videolectures.net/kolokviji_ijs"><span style='font-size:10.0pt'>http://videolectures.net/kolokviji_ijs</span></a></span><span lang=EN-US style='font-size:10.0pt'> (older).</span><span lang=EN-US><o:p></o:p></span></p><p class=MsoPlainText><span lang=EN-US style='font-size:10.0pt'><o:p> </o:p></span></p></div></body></html>
