Properties of Polyvinylidene Fluoride

Kobunshi Kagaku, 1970
1) ポリフッ化ビニリデンの初期着色の原因を明らかにするため, 通常の成形温度で溶融物の示差熱分析, 熱天びん分析およびポリマーからの揮発ガスの定性および定量を行なった. その結果, 初期着色はわずかな発熱と重量損失を伴ったHFの解離反応であることを明らかにした. またポリマーの末端にCl原子を含む場合は容易にHClを遊離し, 初期着色が末端分解に関係することも明らかにした. 2) 次に初期着色の反応機構を明らかにするため, 高温熱分解と初期着色に対してそれぞれ反応の活性化エネルギーおよび次数を計算した. この結果と分子量変化の測定から初期着色反応は不均一反応の一種と考えられ, 主としてを生成することが推定された.

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

Advanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Polyimide‐Linked Hexaazatriphenylene‐Based Porous Organic Polymer with Multiple Redox‐Active Sites as a High‐Capacity Organic Cathode for Lithium‐Ion Batteries

Advanced Materials, EarlyView.
A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...
