A Methodological Pathway for Supporting the Transition From Theory to Practice in Action‐Oriented Research for Transformative Change

Sustainable Development, EarlyView.
ABSTRACT Over recent decades, action‐oriented research has gained prominence in co‐producing actionable knowledge to drive transformative change toward sustainability. However, further methodological developments are needed to support the transition to the application phase of such knowledge.

Carbon nanotubes/α-ZrP sheets for high mechanical performance and flame-retarding polyamides using selective laser sintering

Virtual and Physical Prototyping
The current study presents a facile approach to synthesis carbon nanotube-anchor α-ZrP (CNT@α-ZrP) nanohybrid for multifunctional polyamide 12 (PA12) composites via ball-milling followed by selective laser sintering (SLS) process. Herein, CNTs serve dual

Assessment of Different Technologies in the Fabrication of 3D Printed Tooth Models for Dental Education

European Journal of Dental Education, EarlyView.
ABSTRACT Background 3D printing has emerged as a practical method for fabricating customisable, accurate and affordable dental training models. Numerous 3D printing technologies exist, though there is no standardised comparison to inform their implementation in dental education.

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2233-2254, August 2026.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Cosolvent‐Enhanced Dissolution of Long‐Chain Polyamides: Toward Room‐Temperature Material Recycling of Sustainable Composites

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
Long‐chain polyamides (PAs) such as bio‐derived PA11 and conventional PA12 are difficult to dissolve at room temperature, hindering facile recycling by dissolution‐based methods. This work shows that adding a weak H‐bonding cosolvent to formic acid can rapidly dissolve long‐chain PAs at room temperature by balancing H‐bonding and dispersive ...
