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 ...

Understanding Light‐Soaking Effects in Silicon Solar Cells by Considering Charge Carrier‐Enhanced Atomic Hydrogen Release

Progress in Photovoltaics: Research and Applications, EarlyView.
We show that many hydrogen‐related effects in silicon solar cells can be explained by direct electron‐assisted acceptor‐hydrogen pair dissociation. Most importantly, it leads to a high concentration of atomic hydrogen, which is highly reactive and diffusive. We provide a unified physical description of LeTID.

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

Reasoning Together or Clicking Though? Analyzing Patterns of Group Science Talk On and Off Individualized Computers

Science Education, EarlyView.
ABSTRACT In this article, I examine group science talk within the classrooms of three urban secondary science teachers who regularly use one‐to‐one computers to mediate their NGSS‐aligned science instruction. I combine methods of framing analysis (Goffman 1974; Tannen 1993) and interaction analysis (Jordan and Henderson 1995) to illustrate differences ...
