This Review elaborates on the recent developments and the future opportunities and challenges of fundamental research on semiconductor moiré materials, with a particular focus on transition metal dichalcogenides.

This Perspective suggests a characterization cascade for nanoparticle-based vaccines that takes into consideration the complexity of the materials and of their immunomodulatory responses, providing a roadmap for the preclinical validation of potential vaccine candidates.

This Review discusses how artificial intelligence and machine learning algorithms can be used in combination with X-ray computed tomography to study the composition and the dynamics of microstructures in battery materials with nanoscale resolution.

This perspective analyses the adverse reactions reported for mRNA-based SARS-CoV-2 vaccines in the light of infusion reactions to nanomedicines, which display similar outcomes, suggests possible mechanisms and offers a safety roadmap for vaccine developers.

Nanopatterned materials provide control over mechanical vibrations. This allows for the complete damping of vibrations over more than 5 GHz and for the propagation of hypersonic guided modes at room temperature.

The combination of catalytic platinum particles, nanozymes and a CRISPR-based reaction allows for the quantification of non-coding RNAs at the picomolar range. This assay, CrisprZyme, has a colorimetric readout and works at room temperature without preamplification.

Twisted WSe₂ AB-homobilayers enable the realization of bilayer Hubbard models in the weak interlayer hopping limit.

Quantitative polymerase chain reaction allows the real-time detection of nucleic acids in human samples, representing a gold standard for infection detection, but it cannot be easily converted into a point-of-care approach. Here a strategy is proposed to leverage plasmonic polymerase chain reaction to achieve multiplexed, fluorescence detection of SARS-CoV-2 RNA from human saliva and nasal specimen, showing promise as a point-of-care approach.

Ultrafine catalysts are desirable for the reduction of fuel cell costs but are intrinsically unstable. Here the authors report graphene-nanopocket-encaged PtCo catalysts with exceptional durability under the demanding ultralow-Pt-loading condition while delivering a satisfactory fuel cell performance.

NMR measurements show that the interface between the inorganic and organic components can be tailored to design a highly conducting hybrid solid electrolyte.

Perovskite quantum dots have been proven promising for photonic and optoelectronic applications, particularly, as bright and narrow band emitters for display technology. Despite the advantageous properties, the stability issues have to be resolved to unleash the full industrial potential of perovskite quantum dots in display technology.

Using our company’s CO₂ electrolysers as a model, we describe the challenges involved in incorporating nanomaterial catalysts into industrial-scale electrolysers and suggest ways to more efficiently realize the performance improvements of academic-scale novel nanomaterials at industrial scales.

The recent advent of transition metal dichalcogenides moiré materials is a promising platform for studying correlated electron phenomena and moiré exciton physics.

The transition from a linear ‘take–make–dispose’ economy to a circular economy is gaining momentum. Although there are many opportunities for using nanotechnology to enable circularity, the knowledge gaps related to (eco-)toxicological hazards and the presence of nanomaterials in waste streams constitute significant challenges.

Nanoneedle start-ups are traversing the biotech valley of death — from fundamental university research into commercial development in advanced therapeutics and diagnostics. How can academics make the most of this opportunity?

We will now explicitly ask reviewers to flag up to us and authors whether a simpler model or theory could explain the experimental data in a given manuscript.
