Rapid Diagnostics of Reconfigurable Intelligent Surfaces Using Space‐Time‐Coding Modulation

Advanced Functional Materials, EarlyView.
A fast reconfigurable‐intelligent‐surface (RIS) diagnostics method is proposed based on spatio‐temporal modulation with orthogonal codes. Theoretical analysis demonstrates a clear distinction in code channel power between normal and faulty elements. Simulations validate its feasibility under high fault ratios and varying receiving angles.

Ultrafast Transient Absorption Studies of the Dynamics of Free and Coulombically Trapped Polarons in Doped Conjugated Polymers

Advanced Functional Materials, EarlyView.
Transient absorption measurements of doped conjugated polymer films show that small dopant ions create both free and Coulomb‐trapped polarons regardless of polymer morphology, but large dodecaborane‐based dopant ions create only free polarons even though the large ions cause the films to be more disordered.

Fluorophobic Effect Enables Selective Detection of PFAS in Water with Electrolyte‐Gated Organic Transistors

Advanced Functional Materials, EarlyView.
PerFluoroAlkyl Substances (PFAS) are responsible of major and persistent environmental pollution worldwide. This work demonstrates an ultra‐sensitive sensor for PFAS based on an organic transistor whose gate is functionalized with a binary self‐assembled monolayer containing a perfluorinated molecule.
