- Superior Piezoelectric Properties in Potassium–Sodium Niobate Lead-Free Ceramics

A superior piezoelectric coefficient (d33 = 570 ± 10 pC/N), the highest value reported to date in potassium-sodium niobate-based ceramics, is obtained in (1-x-y)K1-wNawNb1-zSbzO3-yBaZrO3-xBi0.5K0.5HfO3 ceramics. This high d33 value can be ascribed to the co-existence of “nano-scale strain domains” (1–2 nm) and a high density of ferroelectric domain boundaries. Therefore, ternary KNN-based ceramics demonstrate the potential for applications.

2D triangular β-Cu2S nanosheets with large size and high quality are synthesized by a novel method of super-cooling chemical-vapor-deposition. The phase transition of this 2D material from β-Cu2S to γ-Cu2S occurs at 258 K (−15 °C), such transition temperature is 120 K lower than that of its bulk counterpart (about 378 K).

A synapse-emulating electronic device based on organometal halide perovskite thin films is described by T.-W. Lee and co-workers on page 5916. The device successfully emulates important characteristics of a biological synapse. This work extends the application of organometal halide perovskites to bioinspired electronic devices, and contributes to the development of neuromorphic electronics.

On page 5830, Z. G. Wu and co-workers develop a novel approach to make poly(dimethylsiloxane) (PDMS)-based elastomer soft, stretchable and sticky by introducing a small fraction of ethoxylated polyethylenimine (PEIE). Around the PEIE chains, the crosslinking of the elastomer is hindered and results in a gradient of crosslinking density, and hence heterogeneous crosslinked networks. These liquid-like, loosely crosslinked domains in a highly crosslinked network enable higher compliance and larger elongation at break, accompanied by a surface that is highly adhesive to human skin.
