Regulating Phase Evolution and Crystallization Dynamics Enables Low Open‐Circuit Voltage Deficit in Wide‐Bandgap Cu2ZnSnS4 Solar Cells

open access: yesAdvanced Materials, EarlyView.
Bilayer composition‐modulated sulfurization (BCMS) regulates Cu redistribution in solution‐processed Cu2ZnSnS4, suppressing Cu2SnS3 and favoring the direct transformation pathway, while transforming the crystallization from surface‐dominated growth to a more synchronized process.

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

open access: yesAdvanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

The Total Amount of Mercury in Sea Waters

open access: yesNippon kagaku zassi, 1961
著者は海水中の水銀の定量にあたって,水銀をジチゾンにより抽出濃縮後,ふたたびジチゾンにより分光光度定量する方法を提出したが,海水中にはジチゾンにより直接抽出されない状態の水銀の存在も予想される。ここでは海水を硫酸,硝酸あるいは過マンガン酸カリウムと加熱分解後,水銀を定量し,従来の方法と比較検討した。本法を本邦近海海水に適用したところ,酸化分解した海水中の水銀含有量は未処理海水中の水銀含有量の平均約 10 倍程度高い値を得た。なお河川水についても同様の検討を試み,またプランクトン中の水銀量も定量し,これらの結果をあわせ考え,海蔑中の水銀は相当量プランクトンその他の海洋生物に摂取されることを示唆した。

In Situ Formation of a Highly Selective Nickel Single Atom Catalyst for Electrochemical CO2 Reduction to CO

open access: yesAdvanced Materials, EarlyView.
Development of a novel method for synthesizing Ni single atom catalysts for highly selective electrochemical CO2 reduction in situ. This catalyst achieves 100% selectivity for CO and is formed in an industrially relevant cell architecture. Using post‐mortem XRD, STEM, and EDS and operando XAS, the identity of the active site and the mechanism behind ...

Directional Confinement Governed Ion Transport for Efficient Actuation

open access: yesAdvanced Materials, EarlyView.
Structural anisotropy provides an effective means to regulate ion transport in polymer electrolytes. Directionally aligned channels formed by freeze‐drying provide continuous pathways for ion migration, enhancing ion mobility and simultaneously improving the strain and blocking force of ionic actuators.
