The group velocity and frequency of propagation of elastic waves in the radio-frequency domain can be controlled dynamically using arrays of nanoelectromechanical oscillators.
Using lifetime-resolved imaging techniques, engineered nanoparticles can be used to perform multiplexed imaging in the NIR-II region with limited interference from biological tissues, thus by-passing the challenges of conventional deep imaging.
An ensemble multicolour FRET model is introduced and used to extend multicolour barcoding to extreme FRET regimes, enabling in silico design of 580 barcode responses using common dyes and cytometer optics, and permitting fully automated decoding.
Lateral TMD–graphene–topological insulator hetero-devices enable room-temperature optoelectronic transport of the valley-locked spin polarization degree of freedom.
DNA origami-based integrated gene transcription modules enable the rational design of transcription activity. Architectural modalities between gene and RNA polymerase allow the autonomous response to various signals with reprogrammable logic gates.
Direct thermal-to-electric energy conversion can be performed at electronic efficiencies comparable to efficiencies of traditional cyclical heat engines.
Graphene quantum dots inhibit the formation of alpha-synuclein fibrils and induce their dissociation in vitro, and display neuro-protective properties in in vivo models of Parkinson’s disease, with no appreciable long-term toxicity.
Palladium atoms hosted in exfoliated graphitic carbon nitride display improved activity, selectivity and stability compared to state-of-the-art homogeneous and heterogeneous catalysts for Suzuki coupling reactions.
The power output of a thermophotovoltaic device featuring an emitter and a photovoltaic cell increases by more than an order of magnitude when the gap size between the emitter and the cell is reduced to the nanoscale.
A superconducting thin film placed underneath a reconfigurable artificial-spin-ice structure in situ allows controllable geometric frustration with high degeneracy to be achieved.
A switchable electrokinetic nanovalving mechanism is capable of isolating a wide variety of single nanoscopic entities, down to single macromolecules, from an ensemble, and guiding, confining, releasing and sorting them in a broad range of ionic salt concentrations, up to biological buffer levels.
A new superlattice fabrication process on 2D material heterostructures enables the observation of replica Dirac cones in graphene as well as Hofstadter’s fractal magnetic spectrum under triangular and square superlattice symmetries.
