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 ...

Influence of Chain Extender on The Thermal, Rheological, and Supercritical Foaming Behavior of Polyamide‐12

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Chain extender concentration strongly influence the batch foaming behavior of PA 12 under supercritical CO2. Increasing CE content improves melt stability, raises viscosity and broadens the foaming window, enabling fine, uniform cellular structures. The optimal 0.5 wt.% CE yields the highest nucleation density and lowest foam density, about 0.06–0.09 g/

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 ...
