Review on the use of impedance spectroscopy for IPMC-like devices: application, models, and a new approach to data treatment
An extensive review of IPMC-like devices that use impedance spectroscopy as characterization. The proposed model considers the structure of the polymer and aims to be a unique model that can model a device in any humidity and counterion condition.

A multi-cation model for the actuation of ionic membranes with ionic liquids
We propose a model to describe the mechanics and electrochemistry of ionic membranes with ionic liquids. The model allows the study of the migration of multiple mobile cations of different sizes.

Evaluation of two core–shell (Ag2S@- and Bi2S3@-) sensors based on a metal–organic framework (NH2-MIL-125-Ti)/polyaniline for the electroanalysis of uric acid in urine samples
Chemical sensors for the determination of uric acid (UA) in human urine samples have been developed using a composite material based on two core–shells (Ag2S@- and Bi2S3@-) coated with a metal–organic framework (NH2-MIL-125-Ti) and polyaniline (PANI).

Finely tuning the self-assembled architectures of liquid crystal polymers by molecular engineering: phase transitions derived from terminal group variations
Through rational molecular design and modulation of terminal groups in building blocks, as an efficient approach, it is quite efficient to achieve diverse phase transition behaviours and adjust phase structures.

Tuning triboelectric and energy harvesting properties of dielectric elastomers via dynamic ionic crosslinks
The bromination of poly(isobutylene-co-isoprene) rubber introduces a small amount of bromide groups (1–2 mol%) to the elastomer backbone and creates new opportunities for functionalisation, as compared to other saturated and diene elastomers.
