Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

Advanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Electrohydraulic Folding Ring Actuators for Radially Contracting Applications

Advanced Science, EarlyView.
This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify

Additives Enhancing Biodegradability in Plastics and Potential Implications for Textiles: A Mechanistic Review

Journal of Applied Polymer Science, EarlyView.
Mechanistic insights from additive‐assisted plastic degradation guide the design of environmentally adaptive textile fibers. Functional additives enhance oxidative, hydrolytic, enzymatic, and microbial degradation pathways. Translating these strategies requires control of fiber architecture, additive distribution, and environmental interactions ...
