Flat sub-bands induced by moiré patterns and correlation effects are demonstrated in a twisted bilayer of the transition metal dichalcogenide WSe2 through a series of transport experiments.
The integration of silicon-based waveguides with barium titanate thin films enables the realization of efficient electro-optic switches and modulators operating at cryogenic temperatures, offering promising opportunities for quantum technologies.
Semimetal photodetectors provide high-speed and broadband operation but suffer from serious drawbacks such as high dark currents. This Perspective discusses the opportunities offered by topological effects to overcome these issues and improve their performance.
Reprogramming normal cells into tumour precursors involves complex reconditioning of the tissue microenvironment. Cumulative integration of genetic drivers with extrinsic mechanical inputs is now shown to engage YAP/TAZ to rewire cell mechanics and initiate tumorigenic reprogramming.
Creation of bioinspired ion channels that separate ions without compromising selectivity, conductivity or rectification ability has long been a challenge. Integration of metal–organic frameworks into asymmetric nanopore membranes overcomes this limitation.
Programmable DNA building blocks hosting diverse nano-objects assemble into three-dimensional nanoparticle lattices whose geometry is determined by the shape and valence of the DNA block.
Programmable DNA hybridization is used to mediate the self-assembly of substrate-bound DNA-grafted gold nanoparticles into single-crystalline Winterbottom and non-Winterbottom constructions with particular size, shape and orientation.
Two studies investigate the behaviour of localized interlayer excitons in van der Waals heterostructures, offering insights into their dipolar interactions and the effect of moiré trapping potentials for the design of quantum optical applications based on 2D materials.
While integrin-based adhesions are thought to underlie many aspects of cell response to localized tension, another matrix receptor, syndecan-4, has now been shown to act as a mechanosensor, which triggers cell-wide integrin activation and adhesion reinforcement.
This Review provides an overview of the advances in materials and device design that are enabling the realization of implantable electronic interfaces for long-term, multiplexed recording and stimulation of the brain and nervous system.
First-principles calculations predicted electronic topological properties for 2D honeycomb–kagome polymers, which have been now confirmed experimentally thanks to improvements in on-surface synthesis.
New evidence now suggests that the dominant mechanism of extravasation of nanoparticles into solid tumours may be through an active process of endothelial transcytosis.
Two studies shed light on quantum defects in two-dimensional hexagonal boron nitride, identifying an optically addressable spin centre at room temperature and offering microscopic insights into different classes of single-photon emitters.
Finding a competitor for diamond as a good heat conductor remains challenging. Measurements on crystals of cubic boron nitride demonstrate a thermal conductivity of 1,600 W m−1 K−1 at room temperature, rivalling diamond.
