Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

Advanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Collagen Matrix Combined With Hydroxyapatite and Nasoseptal Flap for Skull Base Reconstruction

Laryngoscope Investigative Otolaryngology
Background Extended endoscopic endonasal transsphenoidal approaches (ExEETSA) commonly result in high‐flow cerebrospinal fluid (CSF) leaks that demand robust reconstruction strategies. Although nasoseptal flap (NSF) is a standard reconstructive technique,

Formation of Stable Amorphous Calcium Phosphate and Collagen Assemblies by a Versatile Spray‐Drying Approach

Advanced Functional Materials, EarlyView.
Amorphous calcium phosphate (ACP) microparticles with long‐term and thermal stability are prepared with or without collagen using a scalable one‐pot spray‐drying process. Under simulated physiological conditions, they crystallize into biomimetic bone mineral and, when combined with collagen, form extrudable, fibrillar bone‐like 3D constructs.
