Exploding and Weeping Ceramics Provide Path to New Shape-Shifting Material

Nanoscale study and local chemical analysis of a grain boundary of a (Zr0.9 Hf0.1 O2)0.775 (Y0.5 Nb0.5 O2)0.225 (weeping) sample prepared by FIB. The micrographs are HAADF-STEM and HAADF-HRSTEM images as well as high resolution EDX elemental maps of the sample. Atomic-resolution HAADF micrographs are raw images, showing no significant intensity variation along the grain boundary (GB). The high resolution EDX maps suggest no significant element segregation at the grain boundary.

Discovery could lead to improvements in medical devices and electronics. An international team of researchers from the University of Minnesota Twin Cities and Kiel University in Germany have discovered a path that could lead to shape-shifting ceramic materials...
