Suspensions of 2D hexagonal boron nitride show an anomalously large specific Cotton–Mouton coefficient, enabling the fabrication of a magnetically tuneable and stable birefringent optical device. This device serves as a transmissive light modulator with wavelengths entering the ultraviolet (UV)-C region, representing a technological advance in deep-UV modulation.
A ‘dual-ligand passivation system’ is designed and synthesized to functionalize colloidal quantum dots to realize ultra-high resolution patterns by direct photolithography.
Double ionic gated transistors enable excellent control of the band structure of atomically thin semiconductors. Perpendicular electric fields as large as 3 V nm−1 can fully quench the gap of bi- and few-layer WSe2.
A 2D material based liquid-crystal shows an extremely large optical anisotropy factor in the deep ultraviolet region, showing magnetically tunable birefringence.
A dual-ligand passivation system comprising photocrosslinkable ligands and dispersing ligands enables quantum dots to be universally compatible with solution-based patterning techniques.
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.
A series of emergent electronic orders are observed in an antiparallel twisted WSe2 bilayer. The discoveries provide a powerful platform for simulating quantum phenomena in strongly correlated materials.
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.
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.
