Electro‐Steric Ion Confinement in Polyelectrolyte Networks for Robust Nonvolatile Artificial Synapse

open access: yesAdvanced Functional Materials, EarlyView.
Polyelectrolyte stoichiometry governs ion transport and retention in electrolyte‐gated synaptic transistors. A PSS‐rich network creates electro‐steric ion confinement that suppresses ion back‐diffusion and stabilizes channel doping, enabling robust nonvolatile synaptic memory, linear weight updates, and low‐energy operation.

Reversible Steganography for VQ Indices Using the Modified State Codebook

open access: yes, 2012
[[abstract]]In this paper, we propose an information hiding scheme to embed secret information into the compression code of an index table. First, the codewords neighboring the current processed index along with their closest codewords form a state ...

Solution‐Processed Thin‐Film Transistors With Tunable Temporal Dynamics for Neuromorphic Computing

open access: yesAdvanced Functional Materials, EarlyView.
Solution‐processed CNT and CNT/P3HT ion‐gated transistors exhibit materials‐defined synaptic timescales: fast CNT devices for high‐frequency spiking and slow hybrid devices for temporal integration. Embedding these dynamics into coupled reservoir‐computing and spiking neural network simulations reveals that a Hybrid‐Reservoir / CNT‐SNN architecture ...

Unified Analytical Framework for Understanding the Operational Stability of Blue Phosphorescent OLEDs: Quantitative Insights Into Exciton Recycling and Bimolecular Interactions

open access: yesAdvanced Functional Materials, EarlyView.
Blue phosphorescent OLEDs remain limited by poor operational stability. Here, a unified analytical framework integrating transient photoluminescence and magneto‐electroluminescence is developed to correlate intrinsic material photophysics with electrically driven degradation.
