Nanometallurgy in levitating droplets: high entropy nanoparticles characterisation using pair distribution functions

Structure of multicomponent nanoparticles (NPs) prepared using co-sputtering in ionic liquids (ILs) were not characterised in detail. Nevertheless, information about crystal and local structure of NP/IL suspensions is important for understanding constitution of NPs as well as their time- and air-stability. In some cases, co-sputtered alloys undergo oxidation transformations as well as pre-synthesized single-element nanoparticles can be involved in reactions resulting in formation of multicomponent nanoalloys with complex local structure. Current project addresses important questions circulating around co-sputtered NPs stabilised in ILs. Namely, local structure, oxidation process and their reactions will be characterised using PDF to correlate with complementary SAXS and EXAFS data.
