Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

Advanced 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.

Effect of cyclic loads on fatigue behavior of Ni–Cr–B–Si cladding on 316L(N) SS using PTA process

AIP Advances
316L(N) stainless steel (SS) components in Sodium-Cooled Fast Reactors (SFRs) are hardfaced with NiCrBSi alloy in order to avoid self-welding. Hardfacing is performed by the plasma transferred arc welding (PTA) process, as it gives lesser dilution ...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
