Interfacial Growth of 420 nm Ultrathin and Dense MOFs for Composite Electrolyte to Reduce Li+ Conduction Resistance and Inhibit Lithium Dendrite

Advanced Science, EarlyView.
In this work, an interfacial growth method using PVDF‐HFP enables controlled permeation of 2‐methylimidazole to react with Co2+, forming an ultrathin (420 nm) ZIF‐67 layer by precisely tuning the reaction time. This dense layer promotes lithium salt dissociation and suppresses dendrite growth, while its ultrathin nature reduces Li+ transport resistance,

Digital Twins for the Design, Interactive Control, and Deployment of Modular, Fiber‐Reinforced Soft Continuum Arms

Advanced Intelligent Systems, EarlyView.
A digital twin framework is presented for modular soft continuum arms built from fiber‐reinforced pneumatic actuators. Cosserat rod models describe individual actuators, while virtual assemblies are formed through serial and parallel networks, preserving actuator‐level architecture and arm deformation.

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics
