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,

Improvements in microstructural, mechanical, and biocompatibility properties of nano-sized hydroxyapatites doped with yttrium and fluoride

, 2010
Hydroxyapatite was doped with Y3+ (2.5, 5 and 7.5 mol%) and F (2.5 mol%) ions (2.5YFHA, 5YFHA, 7.5YFHA, respectively) to compare its structural and mechanical properties and cellular response with pure-hydroxyapatite.

Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

Advanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,
