Structural and Chemical Engineering of Sub‐Nanochannel Membranes Toward Ion Selectivity

Advanced Functional Materials, EarlyView.
This review summarizes recent advances in structural and chemical engineering of sub‐nanochannels for ion selectivity. We first introduce fundamental ion transport mechanisms within sub‐nanochannels, followed by strategies to tune pore size, geometry, and surface functionalities, categorized into charge‐based, ion‐recognition, hydrophilic bonding, and ...

Selenium‐Incorporated Polymerized Nonfullerene Acceptors/SWCNT Composites with Polymer‐Assisted n‐Doping for High‐Performance Organic Thermoelectrics

Advanced Functional Materials, EarlyView.
Selenium‐incorporated polymerized nonfullerene acceptor PCB2Se forms a strong supramolecular complex with SWCNTs, enabling a record‐high zT of 0.29. Sequential N‐DMBI doping, mediated through a polymer‐assisted electron‐transfer pathway, successfully converts the PCB2Se/SWCNT composite into an efficient n‐type material with an impressive power factor ...

Fast Track to the Overdoped Regime of Superconducting YBa2Cu3O7‐δ Thin Films via Electrochemical Oxidation

Advanced Functional Materials, EarlyView.
Overdoping high temperature superconductors, such as YBa2Cu3O7‐δ (YBCO), is expected to maxime the critical current density by optimising the condensation energy for a given defect landscape, providing new thrust for the development of fusion enabling coated conductors. Here, precise oxygen control is achieved via an electrochemical method allowing for

How the Carrier Mobility and Seebeck Coefficient of Doped Semiconducting Polymers Are Controlled by Counterion Interactions and Mesoscale Order

Advanced Functional Materials, EarlyView.
Conventional doping of P3HT with F4TCNQ results in poor charge transport. However, when F4TCNQ is exchanged with LiTFSI, the transport characteristics are greatly enhanced. We find the increase in charge transport is directly related to an increase in the mesoscale ordering of P3HT, resulting in longer and better‐connected transport pathways.

Hydrogen‐Bond–Driven Ion Retention in Electrolyte‐Gated Synaptic Transistors

Advanced Functional Materials, EarlyView.
Anion molecular design governs ion–polymer interactions in electrolyte‐gated synaptic transistors. Asymmetric anions induce hydrogen‐bond interactions that suppress ion back‐diffusion and stabilize doping, enabling enhanced nonvolatile synaptic properties.
