Fluorine-containing binders in battery dry electrode processing raise environmental concerns regarding restrictions on per- and polyfluoroalkyl substances. Here, authors show that a fluorine-free binder, Parafilm, can be an alternative to enable primer-free high-loading electrodes with stable cycling for sustainable lithium-ion batteries.

The development of a desktop nanofabrication tool allowing high-resolution patterning and high-throughput synthesis is a long-standing goal in many nanoscience fields. Here, the authors report a system that can write arbitrary patterns composed of diffraction-unlimited features over square centimetre areas.

Scanning probe techniques such as atomic force microscopy can be readily harnessed to prepare nanoscale structures with exquisite resolution, but are not in general suited for high-throughput patterning. Techniques based on contact printing, on the other hand, offer high throughput over large areas, but can't compete on resolution. Now, an approach is described that offers the best of both worlds: by attaching an array of hard, scanning-probe-like silicon tips to a flexible elastomeric substrate (similar to those used in contact printing), it is possible to rapidly create arbitrary patterns with sub-50-nm resolution over centimetre-scale areas.

New two-dimensional semiconductors may exhibit properties beyond inherent semiconducting attributes. Here the authors report protonated semiconducting III–V-derived van der Waals crystals with memristive properties.

Photolithography is an established microfabrication technique but commonly uses costly shortwavelength light sources to achieve high resolution. Here the authors use metal patterns embedded in a flexible elastomer photomask with mechanical robustness for generation of subdiffraction patterns as a cost effective near-field optical printing approach.

A phenomenological model using electronegativity, ionic size, and charge predicts layered cation-eutaxy structures in ternary compounds. Experimental validation supports the model’s reliability and highlights its potential for guiding future materials discovery.

Lateral TMD–graphene–topological insulator hetero-devices enable room-temperature optoelectronic transport of the valley-locked spin polarization degree of freedom.

A technique based on scanning probe microscopy, which uses a two-dimensional array of nanoscopic apertures fabricated at the end of polymer tips to channel light to an underlying substrate, can be used to generate arbitrary patterns with both sub-diffraction limit and larger feature sizes over large areas.

An electrodeposition method is proposed for the growth of elemental metal nanosheets with aligned grain orientation using a confined 2D template. Nucleation and growth are controlled within a confined 2D channel, resulting in nanosheets with high in-plane electrical anisotropy (>10³), highlighting their potential as switching elements.

Kimet al. report a polymeric-based electroluminescent interactive display that actively detects and visualizes an external conductive object under an alternating current. Fingerprint visualization and dynamic monitoring of metallic liquid flow are demonstrated.

Controlling ion transport in nanofluidics is fundamental to numerous material applications but designing a material for ion selection is challenging. Here the authors report a confined van der Waals graphene oxide membrane as cation selective channel for energy generation inspired by neuron electromotive force.

High-throughput imaging has generally been challenging for scanning probe microscopy techniques. Here, the authors introduce binary-state scanning probe microscopy, which uses a cantilever-free elastomeric probes and a hierarchical measurement architecture for parallel topography imaging.

Designing human-interactive displays enabling the simultaneous sensing, visualization, and memorization of a magnetic field remains a challenge. Here, the authors present a skin-patchable magneto-interactive electroluminescent display by employing a magnetic field-dependent conductive gate, thereby enabling 3D motion tracking.

The emergence of applications requiring device-to-device interactivity has to the need to develop conducting electrodes with high optical transparency at low radiofrequencies. Here, the authors demonstrate conductive polymer electrodes with high transparency in the MHz-order frequency range.

Though liquid sensing platforms are highly sought after for emerging biomedical applications, current technology is limited in its capacity to directly sense and store information. Here, the authors report a sensing memory platform that senses, monitors, and stores information on various liquids.

Quantum beats are periodic oscillations originating from the superposition of coherent quantum states. Here, the authors observe exciton quantum beats in the optical spectrum of atomically thin ReS₂, and modulate the intensity of the quantum beat signal by means of light polarisation.
