From high-entropy ceramics to compositionally complex ceramics and beyond
Over the past decade, the field of high-entropy ceramics (HECs) has expanded rapidly to encompass a broad range of oxides, borides, silicides, and other ceramic solid solutions. In 2020, we proposed extending HECs to compositionally complex ceramics (CCCs), where non-equimolar compositions and the…

Enhancing piezoelectric sensing properties of DLP-printed PZT ceramics through controlled powder light absorption
Digital light processing (DLP) printing of PbZrTiO3 (PZT) ceramics is significantly hampered by the inherent high light absorption of the powder, leading to detrimental defects such as shrinkage and cracking, which severely compromise the final sensor performance. Herein, we propose a strategy to…
