Structure and Ionic Conductivity of Halide Solid Electrolytes Based on NaAlCl4 and Na2ZnCl4

open access: yesAdvanced Science, EarlyView.
A solid solution forms in the Na2ZnCl4‐type phase when Al³⁺ substitutes in the Zn²⁺ tetrahedral site; correspondingly, Na+ vacancies form in the Na1 site, allowing for Na hopping. The highest ionic conductivity reaches 1.5*10−5 S cm−1 at 25 °C at the edge of the miscibility gap.

Boosting Photovoltaic Respond Through Molecular Engineering in Organic Manganese (II) Bromide for High‐Sensitivity X‑Ray Detection

open access: yesAdvanced Science, EarlyView.
This work successfully synthesized novel 0D Mn2⁺‐based metal halides (MHs) PTA2MnBr4 and DMA2MnBr4 wafers by a precise molecular design the distance between Mn atoms. The larger PTA⁺ benzene ring structure reduces energy transfer. Importantly, the X‐ray detector based on PTA2MnBr4 wafers achieved the high sensitivity of 1122 µC Gyair−1 cm−2, an low LoD

Synthesis of Elastic Metallic Nickel by Solvent‐Ligand‐Mediated Reductive Assembly

open access: yesAdvanced Science, EarlyView.
The novel elastic metallic nickel, featuring ligands coordinating on the metal surface, is synthesized via rational selection of reduction and structure‐directing organic solvents. Moreover, by modulating solvent composition and incorporating acetic acid ligands, sufficient ligands are enabled to coordinate with the metal surface, thereby improving the
