This study presents a facile approach for fabricating self-supporting, hierarchical bi-metallic boride electrodes with an amorphous/crystalline structure. The unique heterointerface formed within these electrodes enhances mechanical integrity for electrochemical water-splitting applications. The synergistic effect at the heterointerfaces induces an...

Long-range order and short-range disorder (disordered order) enable high out-of-plane ZT ≈ 1.7 in n-type PbSnS2 crystals. The promoted crystal symmetry through alloying Se weakens the distortion of the average long-range order. The induced mass and strain field fluctuations realize short-range disorder. Furthermore, the single-leg device with preeminent...

This work reveals that the ionic conductivity in NASICON-type materials is governed by the interplay between a local factor, the bottleneck volume, and a global factor, Na site ordering. The dominant diffusion mechanism can shift between occupancy-conserved hopping (OCH), preferred when there is strong Na site ordering, and single-ion hopping (SIH),...

Layered Oxide-Based Cathodes In article number 2402169, San-Yuan Chen, Chih-Yen Chen, Ying-Chih Lai, and co-workers prepared a stretchable non-contact energy-harvesting triboelectric textile using a topological-insulator nanocomposite coating and a graphite-like fabric. It was possible to scavenge biomechanical energy in a contactless manner, whilst...

Ether-free poly(quaterphenyl piperidinium) ionomers are prepared by superacid-mediated polyhydroxyalkylations and explored as hydroxide conducting membranes. The para-meta configuration of the quaterphenyl monomer greatly influences polymer backbone flexibility. This provides excellent opportunities to tune and optimize key membrane and ionomer properties,...

A novel approach is developed by incorporating buried selenium seed layers to enhance the performance of Sb2Se3 solar cells through improved heterojunction quality and reduced defect density. This method significantly boosts both V OC and PCE, reaching 498.3 mV and 8.42%, respectively, marking the highest efficiency reported for Sb2Se3 solar cells...
