Design and Characterization of a Dual‐Mode Soft Robotic Flapping Propeller With Pneumatic Stiffness Modulation

Advanced Intelligent Systems, EarlyView.
A novel soft robotic propeller overcomes traditional efficiency‐flexibility tradeoffs via a hybrid pneumatic‐cable actuation strategy. This architecture enables active stiffness modulation with dual‐mode locomotion: tunable biomimetic swimming and earthworm‐inspired wriggling for confined spaces.

Designing Wire Mazes for Replicating Natural Echoes to Study Bat Biosonar Function

Advanced Intelligent Systems, EarlyView.
A validated framework combining efficient physical modeling (multiple scattering model) and deep learning is presented to guide wire‐maze design for bat biosonar studies. This approach rapidly generates large datasets to test acoustic distinguishability among wire arrangements.

Multirobot Aerial Soft Manipulator for Floating Litter Collection

Advanced Intelligent Systems, EarlyView.
A multirobot aerial manipulator enables autonomous floating litter collection by controlling the shape of a flexible rope equipped with a hook‐based tool. Adaptive rope‐shape planning enhances grasping performance while reducing tension, demonstrating the potential of aerial robots for floating litter removal. Removing floating litter from water bodies

Polymorphic behavior of nylon 6/saponite and nylon 6/montmorillonite nanocomposites

Polymer Engineering & Science, 2002
Abstract X‐ray diffraction methods and DSC thermal analysis have been used to investigate the structural change of nylon 6/clay nanocomposites. Nylon 6/clay has prepared by the intercalation of ε‐caprolactam and then exfoliaton of the layered saponite or montmorillonite by subsequent polymerization. Both X‐ray diffraction data and DSC

Modeling Equilibrium Behavior of Nylon 6, Nylon 6,6 and Nylon 6/6,6 Copolymer

Macromolecular Reaction Engineering, 2019
AbstractNylon 6 and nylon 6,6 reaction equilibria depend in a complex way on water concentration and temperature. For example, data sets from six research groups reveal that the apparent equilibrium constant for polycondensation increases with water at low water concentrations, reaches a maximum, and then decreases as the water concentration rises ...

Preparation and Characterization of Nylon 6/Nylon 6 Clay Fibers

Advanced Materials Research, 2012
The drawing, tenacity and thermal properties of nylon 6 (NY6)/nylon 6 clay (NYC) composite fiber specimens prepared at varying NYC contents and drawing temperatures were investigated. The achievable draw ratio (Dra) values of NY6x(NYC)y as-spun fiber specimens initially increase in conjunction with NYC content, and then approach a maximum value, as ...

Vibrational spectra of nylon-6, nylon-6/6, nylom-11 and nylon-12 studied by terahertz spectroscopy

2012 37th International Conference on Infrared, Millimeter, and Terahertz Waves, 2012
Terahertz absorption spectra were measured for nylon-6/6, nylon-6, nylon-11 and nylon-12 by Fourier transform far-infrared spectroscopy. Different spectral features among the four species were interpreted as the characteristics of crystalline conformations of nylons.
