Lukas Porz,Arne J. Klomp,Xufei Fang,Ning Li,Can Yildirim,Carsten Detlefs,Enrico Bruder,Marion Höfling,Wolfgang Rheinheimer,Wolfgang Rheinheimer,Eric A. Patterson,Eric A. Patterson,Peng Gao,Karsten Durst,Atsutomo Nakamura,Atsutomo Nakamura,Karsten Albe,Hugh Simons,Jürgen Rödel +18 more
TL;DR: The possibility to induce and engineer a dislocation microstructure in ceramics that improves the crack tip toughness even though such toughening does not occur naturally after conventional processing is demonstrated.
Optimizing the defect chemistry of Na1/2Bi1/2TiO3-based materials: paving the way for excellent high temperature capacitors
TL;DR: In this article, a reduction of bismuth vacancy and oxygen vacancy concentration by increasing the initial Bi content leads to a significant decrease in dielectric loss, and energy efficiencies of up to 97% can be achieved for the composition Na1/2Bi 1/2O3 −BaTiO3−CaZrO3 (NBT-BT-CZ).

(K,Na)NbO3-based piezoelectric single crystals: Growth methods, properties, and applications
TL;DR: A review of the development of piezoelectric (K,Na)NbO3-based single crystals, including their growth, defect chemistry, domain structures, electromechanical properties, and applications are discussed in this article.
Nanoindentation pop-in in oxides at room temperature: Dislocation activation or crack formation?
Xufei Fang,Hanna Bishara,Kuan Ding,Hanna Tsybenko,Lukas Porz,Marion Höfling,Enrico Bruder,Yingwei Li,Gerhard Dehm,Karsten Durst +9 more
TL;DR: In this article, the size-dependent brittle to ductile transition in SrTiO3 at room temperature using nanoindentation pop-in events is demonstrated, with the latter being the dominating process.
