Elucidating the Friction Catalytic Lubrication Mechanism of Ag Nanoparticles Loaded on MOFs

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel Ag@Co‐BDC nanocomposite lubricating additive is successfully synthesized, which effectively promoted interfacial tribochemical reactions to form a protective tribofilm during friction, resulting in a 16.7% reduction in friction coefficient and a 61.5% decrease in wear rate for base oil.

Eco‐Friendly N, S Co‐Doped Graphene Quantum Dots for Sensing 3‐Nitro‐L‐Tyrosine via Dark State Formation: Evidence From Photoluminescence and Single‐Particle Spectroscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents the selective optical sensing of 3‐Nitro‐L‐tyrosine (3NT), a biomarker associated with neurological and cardiovascular diseases, through the photoluminescence quenching of nitrogen and sulfur co‐doped graphene quantum dots (NS‐GQDs) obtained from garlic.

Disruption of Sulfur Metabolism and Redox Homeostasis in Staphylococcus aureus Using Mechanically Robust Antibiofilm Ti‐Bi Alloys

open access: yesAdvanced Materials Interfaces, EarlyView.
Titanium (Ti) and bismuth (Bi) are selected as alloying elements for the preparation of the Ti‐Bi binary alloy system. Biofilm formation is found to be inhibited by bismuth through the disruption of sulfur metabolism and redox homeostasis, as well as through the direct downregulation of biofilm‐associated proteins.

4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.
