Scaling effects on ferroelectric domains could impact applications for next-generation miniaturized devices. Here brownmillerite oxides are shown to demonstrate ferroelectric domains with widths down to the sub-unit-cell level.

The authors demonstrate nano-engineered thin film thermoelectric materials are attractive for practical solid-state refrigeration with semiconductor manufacturing and ultra-low 0.003-cc materials usage.

Asynchronous and interferometric transient absorption is used to spectroscopically investigate perovskite nanomaterials undergoing light-induced reactions during measurements, monitoring the associated real-time ultrafast photophysical changes of materials.

For system-level integration of wearable electronics, folding method offers simplified processing and enhanced functionality through rigid-soft region separation. Here, the authors introduce a heterogeneous skin patch with multimodal biosensing and responsive drug delivery through folded structure.

A stealthy neural recorder allows for the study of the behaviour of non-human primates in naturalistic settings.

While emission and stability of metal–halide perovskites can be enhanced through heterostructural encapsulation, a controlled synthesis route to such structures is not trivial to realize. Here, the authors design a mechanochemistry-driven protocol for synthesizing highly luminescent CsPbBr₃/Cs₄PbBr₆ heterostructures.

Electroadhesion in soft robotics provides controllable interfacial attraction for robotic functionalities but materials selection is limited. Here, Gao et. al. present an iontronic adhesive to design a soft iontronic gripper with self-healability, tunable adhesion at reduced voltages and rapid release.

Nucleosomes have been shown to impede the elongation of RNA polymerase II during transcription. Here, the authors provide evidence that in fission yeast chromatin remodeller Fun30^Fft3 localizes to transcribing regions to promote transcription by nucleosome disassembly in vivo.

Low-dimensional ferroelectric systems are predicted to have topologically nontrivial polar structures, such as vortices or skyrmions. Here authors present atomic-scale 3D topological polar structures in BaTiO₃ nanoparticles using atomic electron tomography and revealed their size-dependent transitions.

Chiral Ruddlesden-Popper perovskites are of interest as they exhibit circular dichroism in the visible light region. Here authors demonstrate the effect of asymmetric hydrogen bonding on the spin-polarization-based phenomena in chiral 2D perovskites by using structural isomer organic spacers.

A capacitive, fibre-like stretchable strain sensor, formed of two conductors in a double helical structure, can be combined with an inductive coil to create a wireless strain-sensing system for biomedical applications.

The stability of polymer electrolyte membrane fuel cells is limited by the degradation of the cathode catalyst during repetitive start-up/shut-down events — a parasitic oxygen reduction reaction on the anode causes an instantaneous potential jump at the cathode. The issue is now addressed by selectively suppressing the oxygen reduction reaction on the anode by exploiting the metal–insulator transition behaviour of Pt/H_xWO₃ catalysts.

This study demonstrates that an evolutionary conserved, autoregulatory ‘AT-hook’ ___domain of SWI/SNF regulates gene transcription and enhancer activation by modulating SWI/SNF intrinsic catalytic activity and is critical for cell lineage priming.

By combining the MoS2 channel with the PEDOT:PSS floating layer, a new concept device is proposed. This work demonstrates optoelectronic memory operation with high mechanical endurance through a 1,000-cycle bending test, which also offers multilevel memory programming operation based on light intensity and color.

Unrestricted integration of single-crystal oxide films on Si substrates allows for exploitation of emerging functionality of new materials in mature silicon devices. Here the authors integrate epitaxial oxide films with sharp metal-insulator transition on Si substrates by epitaxial lift-off of a freestanding nanomembrane.

The research to utilize chemical potential mismatch for materials synthesis has been limited across the oxide interface. Here, the authors show that directional ionic transport from the VO₂ layers stabilizes the rutile TiO₂ phase at extremely low temperatures, at which epitaxy is difficult, by effectively lowering the activation barrier for crystallization.

It is shown that vanadium dioxide thin films can reversibly accommodate hydrogen within their lattice structures, while demonstrating an insulator–metal–insulator phase modulation with hydrogen doping.

The control of magnetism by electric field is an important goal for future development of low-power spintronics. Here, the authors demonstrate voltage control of magnetism in van der Waals ferromagnetic/ferroelectric heterostructure devices via the strain-mediated magnetoelectric effect.

Combining Lorentz transmission electron microscopy and micromagnetic simulations, we discover a high-density homochiral Néel-type skyrmion phase in a Pt/Co/Ru/Pt/CoFeB/Ru magnetic multilayer structure that is stable at high temperatures up to 733 K. The ___domain phase in this system can be modulated between a high-density skyrmion phase, an isolated skyrmion phase, or a stripe ___domain phase by appropriate tuning of external and material parameters. This finding suggests that multilayer Néel-type skyrmions can be utilized in nonvolatile spin-based electronic devices that require operation at elevated temperatures.
