In previous studies, difficulties were encountered in measuring changes within high-pressure vessels owing to limitations such as sensor connectors and sensor failures under high-pressure conditions. In addition, polymer–gas mixtures experience ins

Conventional co-fired devices comprising a base metal electrode ferroelectric and piezoelectric ceramic are fabricated under specific reducing atmospheres. Such conditions protect the base metal (such as Ni or Cu) from oxidation, and prevent decompos

Lead-free piezoelectric ceramics, (Bi0.70Ba0.35)(Fe0.65Ti0.35)O3 (BBFT), were fabricated via a solid-state reaction method and then treated using different heat-treatment processes (furnace cooling, air quenching (AQ), and water quenching). In all th
