Epitaxy on nanopatterned graphene enables the realization of a broad spectrum of freestanding single-crystalline membranes with substantially reduced defects.
A van der Waals magnetic insulator, NiPS3, hosts a type of polaritonic quasiparticle that emerges from the strong coupling between an optical microcavity mode and spin-correlated excitons.
MFI zeolite crystals with a short b-axis thickness of 90–110 nm and finely controlled microporous environment effectively boosted the Fischer–Tropsch synthesis to olefins by optimizing the product diffusion on the ferric carbide catalyst.
Superconducting diodes, which can operate without dissipation losses at low temperature, usually require a magnetic field to function. A well-designed multilayer device now shows a reversible, non-volatile superconducting diode effect.
Droplet GaAs quantum dots are interconnectable sources of single photons. Near-identical photons from remote GaAs quantum dots now show an interference visibility of 93% with quantum entanglement between the separate photon streams from the two sources.
Non-reciprocal transport in a homogeneous material enables controllable current rectification, but is usually very small. Yet, artificially breaking inversion symmetry in topological insulator nanowires yields a giant magnetochiral anisotropy rectification.
DNA nanotechnology enables the rational design of wide membrane nanopores for the direct and electrical single-molecule sensing of large proteins with hand-held analysis devices.
Hybrid single-electron turnstiles are candidates as a standard for the ampere expressing it with elegant simplicity. Yet, such devices may serve as a standard for the watt with similar elegance and simplicity.
Rhombohedral stacking of two identical non-ferroelectric monolayer transition metal dichalcogenides enables the observation of interfacial ferroelectricity.
In magnetic double nanohelices, the balance of geometrical effects and dipolar interaction results in strongly coupled three-dimensional spin states. This leads to topological features in the stray field, offering a new route to pattern the magnetic induction.
An artificial molecular machine was designed by coupling a chemical equilibrium to a photoresponsive molecular motor. Upon light illumination, the rotary movement of the motor performs work on the chemical equilibrium generating a far-from-equilibrium state.
Quantum fluctuation in a vacuum can induce a measurable force between neutral objects in close vicinity. By dynamically modulating a system of two micromechanical oscillators near an exceptional point in the parameter space, this so-called Casimir effect can induce a non-reciprocal, diode-like energy transfer.
In moiré superlattice van der Waals magnetic materials, competing interactions emerge and can stabilize new magnetic states. Here, stacking-dependent interlayer exchange interactions in small-twist-angle CrI3 bilayers yield an ordered ground state with coexisting ferromagnetic and antiferromagnetic regions.
Dense, short hydrophobic nanochannels have been restacked from two-dimensional quantum sheets to achieve both high areal and volumetric capacitance in thick electrodes under ultrahigh rates.
A retina-inspired two-dimensional material based retinomorphic device exhibits all-in-one perception, memory and computing capabilities for motion detection and recognition.
