Rare‐Earth‐Guided Hierarchical Assembly of Teddy‐Bear‐Like Giant Nickel‐Tungstate Polyoxometalates

Shurong Li, Shi‐Yi Wang, Xu Han, Ming‐Qiang Qi et autres

ABSTRACT The controlled assembly of giant polyoxometalates (POMs) remains a significant challenge in inorganic chemistry. Herein, we demonstrate that rare‐earth ions can direct distinct structural outcomes in nickel‐substituted tungstate systems. Hydrothermal reaction of the flexible precursor [B‐ α ‐SbW 9 O 33 …

Enhanced Stability of All-Inorganic Tin–Lead Perovskite Solar Cells via Additive Engineering

Asayil Alsulami, Ahmed Ali Said, İlhan Yavuz, Luis Lanzetta et autres

All-inorganic tin–lead halide perovskites (CsPb x Sn 1– x I 3 ) are promising absorber materials for next-generation photovoltaics due to their near-ideal bandgaps (∼1.3–1.4 eV) and favorable optoelectronic characteristics. Their practical application, however, is limited by intrinsic instabilities, including Sn 2+ …

Understanding Twisted Triarylboranes from Single Crystals to Heterojunction Blends and Their Applications in Organic Photovoltaics

Jianhua Han, Xu Han, Anirudh Sharma, Jesika Asatryan et autres

The triarylborane family has expanded rapidly as valuable π electron-accepting moieties in organic materials, yet the performance and application of triarylboranes in organic photovoltaics (OPVs) have thus far been limited. Herein, we present a comprehensive platform of 17 distinct triarylboranes to investigate …

Liquid-phase carbonization strategy to recycle waste PET into defect-rich hard carbon for ultralong cycle life sodium-ion battery

Xu Han, Yongyong Cao, Junjie Fu, Yayuan Liu et autres

Hard carbon (HC) is widely regarded as one of the most promising anode materials for commercial sodium-ion batteries due to its excellent electrochemical performance and cost-effectiveness. Although organic polymers offer compositional homogeneity and structural tunability as HC precursors, their high raw material …
