Recent advances in high charge density triboelectric nanogenerators

Cui, Xin; Nie, Jiaheng; Zhang, Yan

2024 International Journal of Extreme Manufacturing

doi:10.1088/2631-7990/ad39ba

Triboelectric materials with high charge density are the building-block for the commercial application of triboelectric nanogenerators (TENGs). Unstable dynamic processes influence the change of the charge density on the surface and inside of triboelectric materials. The charge density of...

Endowing low fatigue for elastocaloric effect by refined hierarchical microcomposite in additive manufactured NiTiCuCo alloy

Feng, Bo; Liu, Helong; Yang, Ying; Shen, Hui; Ren, Yang; Liu, Yinong; Cui, Lishan; Huang, Bingmin; Hao, Shijie

2024 International Journal of Extreme Manufacturing

doi:10.1088/2631-7990/ad35ff

NiTiCu-based shape memory alloys have been considered as ideal materials for solid-state refrigeration due to their superb cycling stability for elastocaloric effect. However, the embrittlement and deterioration caused by secondary phase and coarse grains restrict their applications, and it is...
