Symmetry Breaking Metamaterial Sleeve Actuators

open access: yesAdvanced Intelligent Systems, EarlyView.
Metamaterial sleeves are designed to impart to a soft inflatable structure, nonlinear characteristics within the pressure–volume domain. By tuning the unit cells of the metamaterial sleeve, symmetry breaking is achieved during the inflation–deflation cycle.

Parametric Design of Continuum Robots Using Interlocking Ball Joints

open access: yesAdvanced Intelligent Systems, EarlyView.
Herein, a parametric design methodology is introduced for producing a wide variety of modular ball joint‐based continuum robots. It is demonstrate by designing a magnetically actuated continuum robot for cardiac ablations. The methodology is released as an open‐source computer‐assisted design extension that automatically designs continuum robots based ...

Bioinspired and Sustainable Physical Unclonable Functions with Antibacterial Microstructures

open access: yesAdvanced Intelligent Systems, EarlyView.
An eco‐friendly physical unclonable function (PUF), named HECTA, is developed through spontaneous self‐assembly of hydroxyethyl cellulose (HEC) and tannic acid (TA), forming unique microstructures via hydrogen bonding. Exhibiting high reproducibility, ideal security metrics, and antibacterial activity, this sustainable PUF presents secure ...

Room‐Temperature Material Recycling/Upcycling of Polyamide Waste Enabled by Cosolvent‐Tunable Dissolution Kinetics

open access: yesAngewandte Chemie, EarlyView.
Physical recycling of polyamides (PAs) requires high temperatures due to solvent resistance. Rapid dissolution of PAs in formic acid (FA) using a cosolvent strategy enables room‐temperature recycling and upcycling for utilization of high‐value resources.

Accurate and Efficient End‐Effector Tracking for Quadrupedal Mobile Manipulators through Coordinated Motion and Decoupled Control

open access: yesAdvanced Intelligent Systems, EarlyView.
This article proposes a method that combines coordinated trajectory generation with decoupled tracking control to improve end‐effector tracking accuracy for quadrupedal mobile manipulators. By leveraging whole‐body motion and modeling subsystems independently with interaction forces, the method achieves significant reductions in tracking error and ...

Aluminum Distribution in Ferrierite Zeolites Influences the Performance of Methane Oxidation

open access: yesAngewandte Chemie, EarlyView.
FER‐type aluminosilicate zeolites with preferential Al occupancy at T4 site favor direct methane‐to‐methanol oxidation, while those with Al concentrated at T3 sites within 10‐ring channels facilitate tandem conversion of methane‐to‐methanol on oxidative sites, followed by methanol‐to‐hydrocarbons on acidic sites.
