Acid Site Design for Low Hydration Proton Exchange Membranes

Advanced Functional Materials, EarlyView.
α‐CF2 substitution adjacent to sulfonic acid increases acid strength and enables efficient proton transport under low hydration conditions. This molecular design reduces the dependence of hydrocarbon proton exchange membranes on excessive water uptake, addressing a key limitation of conventional hydrocarbon PEMs while maintaining favorable conductivity

Mitigating Concentration Polarization in Dry‐Processed Ultra‐Thick Cathodes Using a Low‐Viscosity Electrolyte With Soft Li+ Solvation

Advanced Functional Materials, EarlyView.
A low‐viscosity, soft‐solvating methyl ethanoate (ME)‐based electrolyte facilitates electrolyte infiltration into dense dry‐processed ultra‐thick NCM622 cathodes while reducing Li+ desolvation barriers at Li‐metal anodes. Balanced cathode‐scale ion transport and anode‐side interfacial kinetics mitigate concentration polarization and interfacial ...

Noise‐Limited Bit Precision in Ferroelectric Synaptic Transistors for High‐Resolution Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...

Moving electrode electrochemical impedance spectroscopy

, 2023
Electrochemical impedance spectroscopy (EIS) is a powerful tool for analysing material properties and studying interfacial electrochemical processes. During measurement, the sample is contacted via electrodes, and impedance as a function of frequency is determined by applying an AC voltage and measuring the resulting current. In conventional EIS, where
