Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

open access: yesAdvanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Hierarchical Multi‐Material Architectures With Gradient Design for Dynamic‐Range Flexible Tactile Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...

Additive‐Manufactured, Multifunctional Bioreactor Technology for Dynamic Culture of 3D Bioprinted Tissue Models

open access: yesAdvanced Materials Technologies, EarlyView.
We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Electroactive 3D Porous Graphene Foam Impedimetric Biosensor for Ultrasensitive Detection of MCF‐7‐Cells‐Derived Extracellular Vesicles in Human Serum

open access: yesAdvanced Materials Technologies, EarlyView.
A label‐free impedimetric biosensor based on electroactive 3D porous graphene foam enables ultrasensitive and selective detection of CD81 protein and MCF‐7 cell‐derived extracellular vesicles in human serum. Detection limits of 0.048 fg/mL for CD81 and ∼24 EVs/mL are achieved, demonstrating a robust platform for selective, label‐free, and ...
