Asymmetry of the Ferroelectric Phase Transition in BaTiO3

open access: yesAdvanced Materials, Volume 38, Issue 25, 4 May 2026.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Positive and negative regulation of carbon nanotube catalysts through encapsulation within macrocycles

open access: yesNature Communications, 2018
Doping carbon nanomaterials with heteroatoms is the most common way to change their catalytic activity. Here, the authors show that the catalytic properties of single-walled carbon nanotubes can be modified by non-covalently encapsulating them within ...

Resolving Complex Multiscale Structure of Magneto‐ and Electroactive Polymer Composites With an Ionic Liquid

open access: yesAdvanced Materials, Volume 38, Issue 25, 4 May 2026.
Multiscale ionic liquid segregation into nano‐sized domains in the unconfined amorphous polymer phase and into micron‐sized pores enables a coupled magneto‐ and electroactive responses. ABSTRACT A multiscale understanding of the structure of ionogels – nanoparticle‐free polymer composites incorporating ionic liquids – is essential for enhancing their ...

4D Printing of Multimaterial Flexible Magneto‐Active Polymers

open access: yesAdvanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
Magneto‐active polymers are 3D‐printed with tunable mechanical and magnetic properties using both superparamagnetic and hard ferromagnetic fillers. Nano‐CT imaging reveals the spatial distribution of particles within the matrix. Programmable magnetization patterns and soft, flexible architectures enable responsive actuation, offering exciting ...
