Pb(Mg1/3Nb2/3)O3-induced oxygen octahedral distortions and domain growth for concurrent enhancement of multiple parameters in PNN–PZT

Journal of Advanced Ceramics
Enhancing key parameters such as the piezoelectric coefficient (d33), Curie temperature (TC), electromechanical coupling coefficient (kp), and dielectric loss (tanδ) is crucial for improving the overall performance of piezoelectric ceramics. However, the

Measuring the direct piezoelectric charge coefficient for polymer matrix composites

, 2014
To realize proper measurements of the piezoelectric charge constant d33 of materials a certain mechanical load is required. Usually, this implies using a dynamic load (to evaluate the material's response) superimposed on a static preload (to achieve good

Deer Antler δ18O Records Desalination in Israel's Water Supply

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Stable oxygen isotope ratios (δ¹⁸O) in mammalian tissues are widely used to reconstruct past climates, seasonal patterns, and animal origins. These analyses assume that animals drink local rainwater—an assumption now challenged by large‐scale anthropogenic water management.

Rainfall memory and spring atmospheric demand predict herbaceous biomass production in Mediterranean ecosystems

Journal of Ecology, Volume 114, Issue 10, October 2026.
Across 24 years of observations from a long‐term Mediterranean rainfall‐manipulation experiment, herbaceous biomass was shaped by interacting climate controls rather than rainfall alone. Greater winter and spring rainfall memory promoted biomass, whereas high spring vapour pressure deficit reduced it; seasonal thermal variability further modified ...

FedLucra: Federated Learning With Loss‐Utility Controlled Robust Aggregation

Expert Systems, Volume 43, Issue 10, October 2026.
ABSTRACT Federated learning enables collaborative model training without centralizing private data. However, conventional aggregation strategies generally determine client contributions primarily according to local data volume and do not directly consider differences in local model performance. To address this limitation, we propose FedLucra, a modular

Acoustoelectric probe for d33 measurement on piezoelectric thin films

, 2003
An acoustoelectric probe capable of measuring the d33 constant of piezoelectric thin films is presented. The principle used is the direct piezoelectric effect: a mechanical stress is applied to the film surface and the subsequent voltage generated is ...
