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。

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Oil‐Coated Nanoplastics Induce Rapid Membrane Disruption and Severe Intestinal Injury

Advanced Science, EarlyView.
Oil‐rich food contact dramatically amplifies MNP release from plastic takeout containers, producing oil‐coated nanoplastics with altered surface properties and rapid membrane‐disruptive effects. These particles cause severe intestinal barrier damage and immune dysfunction in mice, and risk modeling suggests that long‐term gastrointestinal burdens may ...
