Scanning tunnelling microscopy of doped RuCl₃ shows distinct charge orderings at the lower and upper Hubbard bands, which can be attributed to a correlation-driven honeycomb hole crystal composed of hole-rich Ru sites and a rotational-symmetry-breaking paired electron crystal composed of electron-rich Ru–Ru bonds.

Index-matched fluorescent particles provide a system that directly visualizes ionic crystallization using confocal microscopy, and offers insight into the structure, nucleation and growth of ionic solids.

The authors investigate the origins of chirality transfer across length scales, quantitatively demonstrating how chirality propagates from the molecular to liquid crystal level in filamentous virus systems.

Here, the authors observe that in thin films of antiferroelectric PbZrO₃, substrate clamping enhances the electromechanical response, with expansion purely in the out-of-plane direction, achieving 1.7% strain for 100-nm-thick films.

The authors demonstrate a programmable topological photonic chip with large-scale integration of silicon photonic nanocircuits and microresonators that can be rapidly reprogrammed to implement diverse multifunctionalities.

Understanding the origin of photoinduced water splitting on TiO₂ is crucial to control photocatalytic surface reactions. A photoexcited-hole-transfer-driven mechanism now shows that water dissociation is strongly coupled with dynamic lattice distortion (photoexcited phonons) on TiO₂ surfaces.

Stacked atomic layers that interact via van der Waals forces offer a confined interlayer space for stabilizing unconventional materials or physical states, enabling a versatile platform for engineering structural configurations and properties at the atomic level.

A synthesis method for large-scale conjugated polymers as well as studies under operational conditions show that research on organic mixed ionic–electronic conductors continues to progress.

The scientific community has become more aware of issues surrounding reproducibility. We should remain cognizant that as we develop better understanding we can revise our knowledge of a problem and scientific findings that are considered valid today might not be in the future.

Misalignment-induced moiré patterns and chirality in two-dimensional materials offer vast opportunities for manipulating their properties, but they face challenges in synthesis and structural control.

The 2023 Nobel Prize in Chemistry acknowledged work that paved the way to a nanotechnology worthy of the name.
