A Bone Marrow–Mimetic Hydrogel Enables Dual‐Phase Hemostasis and Vascularized Osteogenesis for Cranial Defects

Advanced Science, Volume 13, Issue 43, 3 August 2026.
A biomimetic, fiber‐reinforced hydrogel (FE‐PDA@Fib/Gel‐TG) that enables dual‐phase cranial defect repair. The system provides: instant hemostasis in the early stage, and sustained co‐delivery of pro‐angiogenic and osteogenic signals for synergistic vascularized bone regeneration.

Interest of polyetheretherketone in prosthodontics

, 2020
Currently, new biomaterials are appearing in dentistry. Polyetheretherketone (PEEK), first used in the aerospace industry and then widely used in the medical field, particularly in orthopedic surgery, is trying to make a place in prosthetic dentistry. This work presents, in a first part, the different chemical, thermal, mechanical and biocompatibility ...

Wear Rate, Particle Morphology, and Biocompatibility of Polyether‐Ether‐Ketone Femoral Heads Against Highly Cross‐Linked Polyethylene Acetabular Cups in Hip Prosthetic Couples

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 8, August 2026.
Graphical abstract summarizing the wear performance, particle characterization, and biocompatibility evaluation of PEEK‐on‐HCLPE hip prosthesis components using a hip wear simulator and in vitro immunological assays. ABSTRACT Biological reactions to wear particles from artificial joint prostheses can lead to osteolysis, ultimately resulting in aseptic ...

Silk Fibroin‐Modified Titanium Implants for Bone Tissue Engineering: Structural Basis, Functionalization and Composite Strategies

Macromolecular Bioscience, Volume 26, Issue 8, August 2026.
Silk fibroin coatings transform inert 3D‐printed porous titanium scaffolds into intelligent, bioactive implants. Leveraging its pH‐responsive structure and tunable degradation, silk fibroin enables spatiotemporal drug delivery, promotes osteoblast activity, and modulates macrophage immunity.

Poly‐Ether‐Ether‐Ketone Melt Behavior in Fused Deposit Modeling Printing Moves

Polymer Engineering &Science, Volume 66, Issue 8, Page 5998-6008, August 2026.
A thin solidified layer forms at the print bed during FDM of PEEK, reducing the effective shear height and raising the effective shear rate above the nominal value. Surface defects emerge once the effective shear rate exceeds a critical value of approximately 750 s−1.

Experimental Evaluation of Wear Resistance of Polymer Materials Used in Piston Compressor Equipment

Механика машин, механизмов и материалов
A new method is proposed for assessing the wear resistance of polymer materials according to the “finger — disk” friction scheme. It involves changing the geometry of the friction zone of polymer samples — the “finger” sphere is replaced by a truncated ...
