Impact of PVDF Homo and Copolymer on Thiophosphate Solid Electrolyte Characteristics and Comprehensive Bulk‐To‐Surface Characterization

Advanced Materials Interfaces, EarlyView.
This study examines how a PVDF‐like binder affects the argyrodite Li6PS5Cl electrolyte properties. Using an approach that combines bulk and surface characterization with electrochemistry, we found a chemical interaction between Li6PS5Cl and PVDF, resulting in partial chlorine substitution by fluorine and slightly reduced ionic conductivity.

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 ...
