V predavanju bom pokazal, kako napredna presevna elektronska mikroskopija (TEM) z <i>in situ</i> ter <i>in</i> <i>operando</i> pristopi omogoča neposreden vpogled v različna neravnovesna stanja med nukleacijo in zgodnjo rastjo delcev. V prvem delu bom predstavil mikrogravitacijske eksperimente nukleacije in zgodnje rasti analogov kozmičnega prahu, pri katerih mikrogravitacija bistveno vpliva na nastanek nukleacijskih jeder in končno kemijsko sestavo nanodelcev. V drugem delu se bom osredotočil na elektrokemijske eksperimente v tekočinski celici znotraj TEM, kjer v nanolitrskih reakcijskih volumnih neposredno spremljamo nukleacijo, zgodnjo rast in raztapljanje nanodelcev pod različnimi elektrokemijskimi pogoji. Rezultati kažejo, da nanometrsko utesnjeni reakcijski volumni niso zgolj eksperimentalna omejitev, temveč predstavljajo posebno kemijsko okolje s svojevrstno reakcijsko kinetiko.</span><span lang=SL style='font-family:"Calibri",sans-serif;mso-ligatures:none'><o:p></o:p></span></p><p class=MsoNormal><span lang=SL style='font-family:"Calibri",sans-serif;mso-ligatures:none'><o:p> </o:p></span></p><p class=MsoNormal><b><span lang=SL style='font-family:"Calibri",sans-serif;mso-ligatures:none'>O predavatelju</span></b><span lang=SL style='font-family:"Calibri",sans-serif;mso-ligatures:none'>: </span><span lang=SL style='font-family:"Calibri",sans-serif;mso-ligatures:none'>Sašo Šturm je znanstveni svetnik na Institutu »Jožef Stefan«, kjer vodi Odsek za nanostrukturne materiale.

In the lecture, I will highlight how advanced transmission electron microscopy (TEM), by combining <i>in situ</i> and <i>in operando</i> techniques, provides access to these transient stages in dynamic environments. In the first part, I will discuss microgravity experiments that mimic the nucleation and early growth of cosmic-dust analogues, showing how microgravity affects nucleation pathways and particle chemistry. In the second part, I will focus on liquid-cell electrochemical TEM, where confined reaction volumes enable direct visualization of nanoparticle nucleation, growth and dissolution under applied electrical bias, demonstrating that nanoscale confinement is not only an experimental limitation but also a distinct chemical environment with unique reaction kinetics.</span><span lang=EN-US style='font-family:"Calibri",sans-serif;mso-ligatures:none'><o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-family:"Calibri",sans-serif;mso-ligatures:none'><o:p> </o:p></span></p><p class=MsoNormal><b><span lang=EN-US style='font-family:"Calibri",sans-serif;mso-ligatures:none'>About the lecturer</span></b><span lang=EN-US style='font-family:"Calibri",sans-serif;mso-ligatures:none'>: </span><span lang=EN-US style='font-family:"Calibri",sans-serif;mso-ligatures:none'>Sašo Šturm </span><span lang=EN-US style='font-family:"Calibri",sans-serif;mso-ligatures:none'>is </span><span lang=EN-US style='font-family:"Calibri",sans-serif;mso-ligatures:none'>a scientific councilor at the Jožef Stefan Institute where he heads the Department for Nanostructured Materials.
