Modulating D33 Coefficients Through In Situ AgF and Ag2O Growth in PVDF Composites for High‐Performance Piezoelectric Nanogenerators

Advanced Materials Technologies, EarlyView.
In situ, nanoparticle doping enhances the piezoelectric coefficient (**d₃₃**) of PVDF to ≈12 pC/N, while in situ growth of AgF and Ag₂O dopants increases β‐phase concentration. The nanogenerator achieves a 35 V open‐circuit voltage and 1.6 µA short‐circuit current, powering 10 blue LEDs and charging a 50 nF capacitor within 10 s.

High‐Pressure Homogenization: An Industrially Scalable Method for Producing PHBH Powders for Selective Laser Sintering

Advanced Materials Technologies, EarlyView.
This article investigates a sustainable approach to producing new powders for selective laser sintering by using high‐pressure homogenization to micronize biopolymers. The approach yields flowable, thermally stable particles with sub‐rounded morphology, enabling 3D printing of dense components with complex geometries.

Enhanced Performance 3‐D Printed PLA Parts through a Photo‐Initiator Mediated UV‐Curing

Advanced Materials Technologies, EarlyView.
This solvent‐free method enhances 3‐D printed PLA parts by incorporating photo‐initiators during fabrication, followed by up to 3 min UV treatment. This process improves PLA's mechanical properties, including a 64% increase in tensile strength, while addressing weak interlayer bonding and outdoor sensitivity.

Growth Factor‐Loaded Mesoporous Silica Particles, Incorporated in Electrospun PCL Fibres, Provide Topographical and Chemical Cues for Tendon Tissue Engineering

Advanced Materials Technologies, EarlyView.
Electrospinning enables the hierarchical assembly of nanofiber‐based scaffolds for tissue engineering. However, encapsulated proteins often undergo structural changes. This study used mesoporous silica nanoparticles (MSNs) as protective carriers, mitigating protein denaturation and supporting controlled release.
