Rolling two-dimensional materials into one-dimensional nanoscrolls unlocks tunable emergent properties; however, existing methods rely on external forces. Now, intrinsically driven scrolling in polar two-dimensional materials mediated by out-of-plane electric polarization is reported, establishing a platform for the design of functional nanoscrolls.

Exciton–polariton superlattices allow sub-picosecond switching of topological phases, paving the way for ultrafast and reconfigurable topological photonic devices.

A ligand-restricted strategy is developed to realize the synthesis of dual-atom catalysts with high pairing ratio and tunable atomic distances.

PEGylated black phosphorus nanosheets boost mitochondrial oxidative phosphorylation, thereby modulating the survival and immune evasion in tumour cells, and further promoting the activation of immune regulation.

A method to make a big family of non-van der Waals superlattices of carbides and carbonitrides based on the delamination and rolling-up of multilayer MXenes is presented. 

Understanding molecular arrangements in mechanistic studies of complex materials is critical but challenging. Here, the authors develop a hierarchical incremental learning protocol to uncover microscopic patterns, improving mechanistic insights obtained

The authors demonstrate a zero-field supercurrent diode effect in NbSe₂/NiI₂/NbSe₂ vertical Josephson junctions, where NiI₂ is a two-dimensional multiferroic material. The diode efficiency is even as a function of field, making the device “resilient" to stray fields from nearby circuit components.

Here, the authors introduce a cryogenic scanning probe photoelectrical sensing technique, termed exciton-resonant microwave impedance microscopy, to measure the excitonic responses in monolayer MoSe2 and identify exciton polarons and their Rydberg states.

Two studies demonstrate wafer-scale synthesis of hexagonal boron nitride memristors compatible with CMOS technology and introduce opto-reconfigurable devices for broad-spectrum neuromorphic applications.

Terahertz technology has the potential to push the speed limit of future opto-electronic applications, but the large free-space wavelength of terahertz light hinders nanoscale device implementation. Now, the confinement of terahertz light to the nanometre scale is demonstrated using phonon polaritons in hafnium-based van der Waals crystals.
