Ion‐Driven Regulation of Ca2+ Flow by Ti/Zn Composite Activates ERK/MAPK Signaling and Maintains Mitochondrial Homeostasis to Promote Macrophage‐Mediated Bone Regeneration

Advanced Science, EarlyView.
A 3D‐printed interpenetrating Ti/Zn composite enables sustained Zn2+ release to regulate intracellular Ca2+ redistribution, preserve mitochondrial homeostasis, activate ERK/MAPK signaling, and promote M2 macrophage polarization, thereby enhancing osteoimmune‐mediated bone regeneration and peri‐implant osseointegration.

3D Printed Ordered Porous Architectures of Functional Metal Tellurides for Ultra High Mass‐Loaded Ammonium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Aqueous ammonium‐ion batteries (AAIBs) are emerging as promising alternatives for next‐generation energy storage. To overcome the limited ion diffusion associated with ultrahigh mass‐loading electrodes, this work develops a 3D‐printed porous conductive electrode of metal‐telluride fabricated via selective laser melting technique.

Corrosion-fatigue of additively manufactured Ti6Al4V

Journal of the Mechanical Behavior of Biomedical Materials
Additive manufacturing (AM) has been used to process complex one-of-a-kind patient-specific implants, along with on-demand manufacturing with innovative geometries. AM parts are more susceptible to fatigue failure due to inherent porosities than conventionally processed parts.

Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods

Advanced NanoBiomed Research, EarlyView.
Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...

Woven Eutectic Lamellar Structures Lead to Ultrahigh Strength and Energy Absorption Capacity in Additively Manufactured Lattice Structures

Small Structures, Volume 6, Issue 5, May 2025.
Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield
