Texturing of lead free piezoelectric ceramics

, 2013
Texturing of the lead-free system Ba0.92Ca0.08TiO3 (BCT) was investigated focusing on density, degree of texture and piezoelectric response. BCT templates were prepared in a two-step molten salt synthesis to achieve the anisotropic growth needed for the template morphology.

Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

Advanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...
