Whereas gold and rust are well-understood in their bulk form, our in-situ experiments revealed a complex and scientifically interesting phase behavior of Au and Fe2O3 nanoparticles. We found that binary combinations of Au and Fe2O3 nanoparticles exhibit intriguing and unexpected phase behavior. We discovered that Au and Fe2O3 fuse, in a quasi-fluid fashion, to form heterostructured particles that undergo a series of composition and temperature dependent metamorphoses.
