Antioxidant Dyes for Polypropylene Fiber
The Journal of the Society of Chemical Industry, Japan, 1971 ポリプロピレン繊維は種々の用途に用いられているが, この繊維の欠点の一つは熱や光によって酸化されやすいことである。洗たく, 乾燥あるいは染色などの操作時に繊維中の抗酸化剤は容易に脱落してしまう。抗酸化性化合物と色素をトリアジン環で連結することにより抗酸化性を持つ染料を合成した。この新しい型の染料を用いて繊維の着色と熱安定性の向上が染色によって同時にえられた。染色繊維のオーブン劣化時間およびフィルムの 140℃ での酸素吸収法によってえられた誘導期間によって合成した染料がすぐれた抗酸化性を持っていることを示した。

A Review of Failure Modes and Safety Strategies of Lithium‐Ion Batteries from Materials to Systems
Advanced Science, EarlyView.A cascade‐aware framework is presented for lithium‐ion battery safety, linking thermal runaway initiation, acceleration, runaway reaction, and propagation with material‐, cell/pack‐, and system‐level interventions. By integrating failure mechanisms, quantitative safety indicators, and staged interception strategies, this review highlights how safer ...
