A Hierarchical, Model‐Based System for High‐Performance Humanoid Soccer

open access: yesAdvanced Intelligent Systems, EarlyView.
A hierarchical model‐based humanoid soccer system built on ARTEMIS integrates compliant mechanism design, in‐gait kicking, perception, localization, collision‐aware navigation, and behavior planning. Hardware–software codesign aligns mechanical design and control strategy with the requirements of autonomous soccer.

Mechanochemical Defluorination of Polytetrafluoroethylene (PTFE) With Base Metals

open access: yesAngewandte Chemie, EarlyView.
Polytetrafluoroethylene (PTFE) mechanochemically reacts with safe‐to‐handle, abundant, and inexpensive base metals Zn and Al, as well as with metals like Cd and Pb, to produce sp2‐carbon and industrially important metal fluorides. The reactivity presents PTFE as a mechanochemical fluorination agent, with opportunities for closed‐loop reductive ...

An Active Knee–Ankle–Foot Orthosis With Torque‐Dense, Low‐Impedance Knee Actuation

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents the simulation, design, and clinical validation of a robotic active KAFO with torque‐sensitive actuation. By passively and continuously adapting the transmission ratio in response to the knee torque, the torque‐sensitive actuator overcomes the tradeoff between torque, weight, and impedance observed in conventional robot actuators,

Site‐Selective Anion‐Cation Regulation of Sulfide Electrolyte Enables Low‐Pressure Dendrite‐Suppressed All‐Solid‐State Lithium Metal Batteries

open access: yesAngewandte Chemie, EarlyView.
Site‐selective Al/F/Cl regulation couples sulfide‐framework stabilization with favorable interphase chemistry in argyrodite Li6PS5Cl. Al incorporation reinforces the redox‐sensitive tetrahedral framework, while F/Cl regulation promotes Li+ transport and guides the formation of a LiF/LiCl‐rich passivation interphase.

Demonstration of a Two‐Electron Pathway in Piezoelectric Mechanochemistry: Synthesis and Mechanical Adaptation of Polythiourethane

open access: yesAngewandte Chemie, EarlyView.
A mechano‐triggered polythiourethane (PTU) synthesis mediated by a two‐electron pathway. The polymerization proceeds efficiently (<1 h) under focused ultrasound, achieving >90% conversion without any conventional base catalyst. The approach demonstrates broad compatibility with various thiol/isocyanate monomer combinations, highlighting its synthetic ...
