Enhanced Lattice Polarization and Directed Charge Transport Toward Pt Surface Sites Accelerate the Volmer Step in Piezocatalytic H2 Evolution on Co‐Doped BiFeO3

Advanced Energy Materials, Volume 16, Issue 23, 17 June 2026.
We report a Pt‐decorated Co‐doped BiFeO3 (Pt/BCFO) piezocatalyst achieving an H2 evolution rate of 1896.4 µmol g−1 h−1. Co‐doping induces lattice distortion, enhancing piezoelectric polarization, while Pt sites promote water dissociation. Embedded in a poly(vinylidene fluoride) matrix, Pt/BCFO enables efficient mechanical energy harvesting and catalyst

Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

The Anatomical Record, Volume 309, Issue 6, Page 1583-1598, June 2026.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

Microstructural Engineering of Sodium Potassium Niobate for Enhanced and Temperature‐Stable Electromechanical Response

International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.
This study investigates the synergistic effects of Ti‐doping and K5.4Cu1.3Ta10O29 (KCT) co‐modification on KNN ceramics to develop sustainable, lead‐free piezoelectrics. Co‐modification significantly enhances electromechanical coupling and the mechanical quality factor. The optimized KNN‐Ti‐KCT system achieves thermal stability comparable to commercial
