In Situ Atmospheric Plasma Treatment Enables First‐Layer Adhesion of PEEK on Borosilicate Glass for FDM‐Printed Non‐Assembly Mechanisms

Polymer Engineering &Science, EarlyView.
A printhead‐mounted plasma nozzle activates the PEEK melt and the borosilicate print‐bed at the instant of contact. Only this simultaneous in‐situ activation of both interfaces yields reliable first‐layer adhesion (0.22 MPa). ABSTRACT Fused deposition modeling of poly‐ether‐ether‐ketone (PEEK) requires a high‐temperature build plate, yet PEEK does not ...

Photogenerated fluphenazine radical cations for antiviral functionalization of polypropylene masks

Polymer International, EarlyView.
Fluphenazine impregnated into nonwoven polypropylene masks is photoexcited to a radical cation, which inactivates viruses on the polymer surface without causing damage to the masks. Abstract The incorporation of photoactive molecules into polymeric substrates offers a compelling route to introduce advanced functionality while preserving the host ...

Current Trends and Future Prospects of Integrating Electrospinning With 3D Printing Techniques for Mimicking Bone Extracellular Matrix Scaffolds

Journal of Polymer Science, Volume 63, Issue 6, Page 1481-1504, 15 March 2025.
ABSTRACT This article presents a review of the recent findings on the combination of electrospun nanofibers and three‐dimensional (3D)‐printed structures for extracellular matrix (ECM) scaffolds for bone tissue engineering. We explore the synergy between electrospinning (ES), which produces highly porous, fibrous structures from materials like collagen

Predictability of obstructive sleep apnea with a somesthetic screening score: Development and preliminary validation in a prospective study

Sleep Research, EarlyView.
This prospective study developed a two‐step clinical scoring system for obstructive sleep apnea (OSA) screening based on patients’ somesthetic perception of oropharyngeal airflow. The Intermediate Score (IS ≥ 7.5) achieved 73% sensitivity and 77% specificity (AUC = 0.7754; OR = 8.96).

Vine Tendril‐Inspired Cold‐Programmable Shape‐Memory Polymer Composites Using Sugar Beet Pulp

Small, EarlyView.
Vine tendrils inspire a bio‐derived, cold‐programmable shape‐memory polymer composite (SMPC). Magnetically guided sugar beet pulp creates mesoscale heterogeneity within a glassy matrix, producing built‐in mechanical asymmetry for rapid, solvent‐free programming by simple stretching.
