An Injectable Electroactive Hydrogel Engineered for Stable Bioelectronic Interfaces

Advanced Materials Interfaces, EarlyView.
Injectable electroconductive hydrogels enable soft, conformal, and stable bioelectronic interfaces for electroceutical therapies. A catechol‐modified hyaluronic acid/alginate/edge‐functionalized graphene platform combines wet adhesion, shear‐thinning injectability, tissue‐matched mechanics, and electrochemical functionality.

On the Friction and Wear Mechanisms of Electrified Steel Contacts in CO2: Unveiling the Role of Carbon‐Rich Tribofilms Under Dry Sliding Conditions

Advanced Materials Interfaces, EarlyView.
This study investigates friction and wear of AISI 52100 steel under dry sliding in CO2, air, and N2 atmospheres, with and without contact electrification. CO2 forms a stable carbon‐rich tribofilm that reduces friction by ∼30% and wear by ∼85%. High‐resolution TEM, EELS, and molecular dynamics reveal pressure‐dependent lubrication mechanisms, showing ...

Tunable 3D‐Printed Static Mixers for Gradient Bioprinting With High Cell Viability

Advanced Materials Technologies, EarlyView.
ABSTRACT The fabrication of native tissue‐like structures with gradual transitions in material properties, cell types, and growth factors remains a major challenge in biofabrication due to the lack of suitable methods. Mimicking the hierarchical organization of living tissues is essential for functional models, yet creating gradient, multimaterial ...
