Algoritmi za obdelavo slik elektronske mikroskopije pri atomski ločljivosti
Ana Rebeka Kamšek, Simon Čopar, Goran Dražić
Magistrsko delo
Oznake: elektronska mikroskopija;obdelava slik;elektrokataliza;nanodelci;
Vrstična presevna elektronska mikroskopija na identični lokaciji je metoda za karakterizacijo materialov, ki omogoča slikanje istih območij materiala pred in po nekem postopku. Uporaba te metode za opazovanje spreminjanja katalizatorjev za uporabo v vodikovih gorivnih celicah, ki so v obliki kovinsk ...

Oznake: materiali;nanodelci;zlitine;STEM;elektrokataliza;elektrokatalizatorji;
Nanoparticulate electrocatalysts for the oxygen reduction reaction are structurally diverse materials. Scanning transmission electron microscopy (STEM) has long been the go-to tool to obtain high-quality information about their nanoscale structure. More recently, its four-dimensional modality has em ...
