  • Innovative approach to controlled Pt–Rh bimetallic nanoparticle synthesis 
    Jensen, Martin; Gonano, Bruno Raymond Gino; Kierulf-Vieira, Walace; Kooyman, Patricia J.; Sjåstad, Anja Olafsen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Precise control of the elemental composition and distribution in bimetallic nanoparticles is of great interest for both fundamental studies and applications, e.g. in catalysis. We present a new innovative and facile synthesis ...
  • Variable temperature in situ TEM mapping of the thermodynamically stable element distribution in bimetallic Pt-Rh nanoparticles 
    Jensen, Martin Myhre; Kierulf-Vieira, Walace; Kooyman, Patricia J.; Sjåstad, Anja Olafsen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    We report here the first variable temperature in situ transmission electron microscopy (TEM) study on smaller Pt–Rh nanoparticles (≤24 nm) under vacuum conditions. Well-defined 50 at% Pt/50 at% Rh Pt–Rh solid solution and ...
