TL;DR: This paper describes a two-step method to determine the three-dimensional orientations of ferroelectric single crystals based on an improved rotating orientations XRD method that is a fast, flexible, and waste-free method for crystallographic orientation.

TL;DR: The degraded piezoelectric and dielectric properties of thin PMN-PT were found to increase significantly, by decreasing domain size, and the fine domain structure was found to be stable at 3kV/cm after 7.0×10(5) negative-pulse cycles, hence, enabling PMn-PT crystals for high-frequency (>20 MHz) ultrasound-transducers.

TL;DR: In this paper, a bridge-type shear-mode piezoelectric energy harvester based on Pb(In1/2Nb 1/2)O3-Pb(Mg1/3Nb2/3)PbTiO3 (PIN-PMN-PT) single crystals was proposed to address the issue of sustainable energy supplies for IoT systems.

TL;DR: Results indicated that V. harveyi could induce tissue-specific metabolic responses in mussel M. galloprovincialis, meaning that the immune organ, digestive gland, was more sensitive than gill, and this work studied the differential metabolic responses induced by Vibrio Harveyi in digestive gland and gill tissues using NMR-based metabolomics.

TL;DR: In this article, the anisotropy of dry cohesive and cohesionless powders and the effect of particle shape and sample deposition method on anisotropic properties were investigated using a cubical triaxial tester, where two different deposition methods, plunging and tapping, were used to prepare cubical (50 mm) test samples.
