On the design of a piezoelectric self-sensing smart composite laminate

open access: yesMaterials & Design, 2022
The structural health monitoring of composite laminates is a rapidly emerging need in structural applications. Different real-time sensors integrated into laminates have been proposed, such as fiber Bragg gratings and piezoceramics.

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

open access: yesAdvanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Birefringence of lead titanate (PbTiO3) [PDF]

open access: yesJournal of Applied Crystallography, 2004
Since lead titanate was first grown in single-crystal form in the 1930s, several independent reports of its linear birefringence have been published. Whilst there is overall qualitative agreement on its behaviour with temperature, the absolute values show some degree of variation.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

open access: yesAdvanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Dielectric properties of ceramics in lead zirconate titanate - lead magnesium niobate system [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2004
In this study, the xPb(Zr0.52Ti0.48)O3 - (1-x)Pb(Mg1/3Nb2/3)O3 (when x = 0, 0.1, 0.3, 0.5, 0.7, 0.9, and 1.0) ceramic composites are prepared from PZT and PMN powders by a conventional mixed-oxide method.

Topotatic‐Like Phase Transformation of Amorphous Lead Titanate to Cubic Lead Titanate

open access: yesJournal of the American Ceramic Society, 2002
The crystallization process of lead titanate (PT) prepared using the polymeric precursor method was investigated using X‐ray diffractometry, Raman spectroscopy, electron microscopy, and X‐ray absorption spectroscopy techniques. The results showed that amorphous PT was formed by an O–Ti–O structure composed of fivefold and sixfold oxygen‐coordinated ...
