System Identification of Robotic Fish Swimming Reveals Roles of Reactive and Resistive Fluid Force in Two Distinct Swimming Gaits

open access: yesAdvanced Intelligent Systems, EarlyView.
System identification and particle image velocimetry reveal how a modular robotic fish changes thrust physics across gaits. A traveling‐wave, fish‐like motion draws thrust from resistive drag, while a resonant standing‐wave motion is driven by reactive pressure.

Rheo-optical characterization of the shear-induced non-isothermal crystallization of polyamide 6

open access: yeseXPRESS Polymer Letters
The use of rheo-optical techniques to evaluate crystallization in polymer processing has many advantages; however, it is still little seen. Shear-induced crystallization of polyamide 6 (PA6) was here proposed and studied with these techniques.

Ein Dithio‐Vinylthio‐C2‐Synthon, das kristalline und lumineszierende, schwefelhaltige Polymere ermöglicht

open access: yesAngewandte Chemie, EarlyView.
Die Umsetzung von CaC2 zu einem modularen C2‐Baustein ermöglicht die Synthese eines α,ω‐Bis(vinylthio)‐Monomers sowie dessen Weiterumsetzung zu kristallinen, sequenzdefinierten, schwefelfunktionalisierten Polymere. Dichte Thioether‐Cluster induzieren nichtkonventionelle Lumineszenz und ermöglichen eine präzise Kontrolle der Struktur‐Eigenschafts ...
