Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal [PDF]

open access: yesAdvanced 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 ...

Avaliação da polaridade superficial de náilons por espectroscopia de fluorescência Evaluation of surface polarity of nylons by fluorescence spectroscopy

open access: yesPolímeros, 2005
Este trabalho avalia a polaridade superficial de cinco tipos de náilons: -6, -11, -6,6, -6,10, -6,12 usando a escala do pireno, py. Esses náilons podem ser classificados em duas categorias: AB (nálion-6 e -11) e AABB (nálion-6,6 e 6,10 e -6,12). A escala

Toward the Bioremediation of Nylon Waste Materials: Genome Mining Leads to the Identification of a Thermostable Laurolactamase From Thermopolyspora flexuosa [PDF]

open access: yesChemSusChem, Volume 19, Issue 1, January 2026.
To enhance nylon waste remediation, genome mining was used to identify a thermostable laurolactam hydrolase from Thermopolyspora flexuosa with activity against an important cyclic nylon derivative. Substrate scope analysis and structural modeling revealed key features controlling enzyme‐substrate compatibility, providing a promising foundation for ...
