Unlocking the Power of Quercetin‐Encapsulated Mesoporous Bioactive Glass Nanoparticles: A Multifunctional Approach to Bone Regeneration

open access: yesAdvanced Engineering Materials, EarlyView.
Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

Additive Manufacturing of Gradient Stiffness Honeycombs Using Thermoplastic Polyurethane Composite Material Variations

open access: yesAdvanced Engineering Materials, EarlyView.
By combining porous, solid, and carbon fiber‐reinforced thermoplastic polyurethane within a single 3D printed honeycomb structure, this current work achieved precise control over spatial stiffness while ensuring strong interlayer adhesion. The findings demonstrate enhanced energy absorption and densification strain, outperforming traditional uniform ...
