Ultrafine‐Grained Materials With Antibacterial Properties: A Novel Approach to Reducing Spinal Implant‐Associated Infections

open access: yesJOR SPINE, Volume 8, Issue 3, September 2025.
This is the first in vivo study to demonstrate that ultrafine‐grained stainless steel possesses potential antibacterial properties capable of resisting the adhesion of bacteria and, subsequently, microcolony formation and biofilm maturation. Incorporating ultrafine‐grained materials in the manufacture of orthopedic implants or medical devices could ...

4D Printing of Composite Thermoplastic Elastomers for Super‐Stretchable Soft Artificial Muscles

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 29, August 5, 2025.
ABSTRACT This study explores the development of soft, super‐stretchable artificial muscles by 4D printing of composite thermoplastic elastomers. A propylene‐based elastomer, combined with carbon black (CB) nanoparticles, is utilized to develop nanocomposite elastomers with enhanced mechanical properties.

A Method for the Evaluation of Crack Tip Opening Loads Based on Strip Yield Modeling of a Propagating Crack

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 8, Page 3338-3352, August 2025.
ABSTRACT Based on the strip yield model for propagating cracks, the current paper proposes a new method for the evaluation of crack tip opening loads. It is based on the theoretical analysis of shapes of the compliance offset curves for various applied stress levels and R ratios, which indicates that the inflection point of the curve is a good ...
