Catalytic metals dissolved in liquid gallium remain atomically dispersed and dynamically active. The configurational dynamics of the metal atoms enables them to adopt a specific configurational alignment with the reactants to facilitate selective propylene synthesis from two different hydrocarbon feedstocks.
A DNA origami nanoturbine is designed as a rotary motor that draws power from an ion gradient or electrical potential across a solid-state nanopore. Single-molecule experiments demonstrate that the turbine can drive a DNA bundle into sustained unidirectional rotation, with the preferred rotation direction set by the chirality of the turbine.
Nanoscale inhomogeneity is a major barrier to achieving high nonlinear efficiency in nanophotonic lithium-niobate waveguides. Using adapted poling in the waveguide — to circumvent the inhomogeneity and restore ideal phase matching — is shown to break through this efficiency limit.
In a major advancement for synthetic biology, dynamin A has been identified as a minimal component enabling cell division in synthetic cells, moving us one step nearer to realizing the ambition of creating synthetic life forms.
Two-photon lithography has advantages for precise additive manufacturing at the nanoscale, but its printing speed is currently too slow for large-scale practical applications. A sensitive photoresist based on zirconium oxide hybrid nanoparticles is shown to increase the linear printing speed of two-photon lithography up to the order of metres per second.
Drawing inspiration from classical semiconductor technology, a strategy to address many quantum dots through a small number of control lines is presented. The two-dimensional array consisting of 16 germanium quantum dots can be tuned in the few-hole regime with odd charge fillings and individually addressable tunnel couplings.
Self-assembled single vacancies in a 2D transition metal dichalcogenide are used to fabricate atomically precise quantum antidots. The resulting antidots have tunable quantum hole states, which are robust to oxygen substitutional doping, and could have applications in quantum information and photocatalysis technologies.
This Review analyses the mechanisms of light extraction from perovskite light-emitting diodes and suggests new approaches towards ultrahigh electroluminescence efficiencies.
DNA-origami nanostructures self-assembled at milder physicochemical parameters in magnesium-free conditions achieve structural complexities akin to those formed by thermal annealing at elevated temperatures, and open a route to assembling DNA nanomachines in physiological conditions.
By integrating a 3D nanopositioner with a solid-state nanopore and surface-tethered molecules, precise spatiotemporal control over single DNA strands is achieved, enabling numerous re-reads and raising the signal-to-noise ratio far beyond previous solid-state nanopore methods.
Monolayer MoS2, a two-dimensional semiconductor, was directly synthesized on polymer and ultrathin-glass substrates at 150 °C using a metal–organic chemical vapour deposition strategy. The high-quality MoS2 films enabled the construction of various integrated circuits on flexible substrates without the need for an additional transfer process.
