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 ...

n‐Type Semiconductor Hydrogels for Tunable Organic Electrochemical Transistors Operation and Evaporation‐Driven Synergistic Energy Harvesting and Thermal Management

Advanced Functional Materials, EarlyView.
This study develops a tunable n‐OSC hydrogel (PBFDO‐PAAc) platform with a tunable porous network and thermoelectric properties. It demonstrates the first report of n‐OSC hydrogels for evaporation‐driven hydrovoltaic‐thermoelectric electricity generation as well as chemically dedoping‐mediated OECT working mode reconfiguration. This work expands n‐OSCs’

Multifunctional Solid Polymer Electrolyte Films Integrating Intrinsic Self‐Healing and Dual Photo‐/pH‐Responsive Ionic Sensing for Intelligent Flexible Electronics

Advanced Functional Materials, EarlyView.
Multifunctional solid polymer electrolyte (SPE) films integrating intrinsic self‐healing, mechanical stretchability, and dual photo‐ and pH‐responsive ionic conductivity are developed. Constructed from thermoplastic polyurethane (TPU) and hydrogen‐bonded poly(thiourea triethylene glycol) (PTUEG3), these films form a dynamic supramolecular network ...

Aberration-corrected TEM study on the influence of HCO3−/ CO32− concentration and Cl− on FeCr15Ni15Mo2 alloy in alkaline solutions

Journal of Materials Research and Technology
Carbonation of concrete pore solution results in a drop of pH value and introduction of HCO3−/CO32−. The drop of pH has been identified as an important factor in causing general corrosion by destabilizing passive films on stainless steels.
