Advanced Science, Volume 13, Issue 18, 27 March 2026.Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Chapter 1: High-performance polyethylene fibers
Advanced Industrial and Engineering Polymer Research, 2022 In 1960, Treloar [1] published a seminal paper showing that the stiffness (E-Modulus) of an extended viz. fully stretched polyethylene and polyamide chain is close to 200 GPa, which is appr. the same stiffness as steel.

Fallschirmspringen, Paragliding und Wingsuit‐Fliegen: Im freien Fall
Physik in unserer Zeit, Volume 57, Issue 2, Page 74-78, March 2026.Mit nichts als Schwerkraftantrieb vom Himmel zu fallen, führt zu den schnellsten Sportarten, aber auch zu den gefährlichsten. Zusammenfassung Fallschirmspringen wird erst seit 1951 als offizielle Sportart betrieben. Moderne Fallschirme sind sehr gut steuerbar, weshalb zum Beispiel das Zielspringen immer anspruchsvoller wird.
