Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

The Structure of Crystalline Polyacetylene

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1962
チーグラー型の触媒を用いて合成したアセチレン重合体は,典型的有機半導体として挙動し,非局在性の不対電子をもち,長い共役二重結合系からなる重合体であると推測されたが,この重合体の構造やその共役系の長さについてより詳しく調べるために,赤外吸収スペクトル,X線回折図および比抵抗などを測定し,常磁性共鳴吸収の結果とあわせて,これらアセチレン重合体の構造に関し推論を試みた。アセチレン-d2より合成されたポリ(アセチレン-d2)とアセチレン重合体の赤外吸収スペクトルを観測し,それらの各バンドを比較し,各バンドの帰属を行なった。その結果,このアセチレン重合体は対称性の大きいトランス・トランス型共役二重結合からなる平面ジグザグ構造であることを証明した。X線回折図によれば,重合体分子面相互の間隔は3 ...

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

MnI‐Functionalized Covalent Organic Framework as Efficient Electrocatalyst for CO2 Reduction in a Catholyte‐Free Zero‐Gap Electrolyzer

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.
