In a breast cancer animal model, long-term exposure to carbon nanotubes promotes tumour invasiveness and metastasis through activation of local and systemic inflammation.
Magneto-transport measurements on thin metallic crystals of the transition metal dichalcogenide PtSe2 show signatures of ferro- and antiferromagnetic order depending on the number of layers and first-principles calculations suggest Pt vacancies at the surface as a plausible cause.
The atomic thickness of two-dimensional materials enables the realization of a small footprint transistor architecture for photoswitching logic computing in a single cell.
A nanoporous polyimide film filled with a solid polymer electrolyte has high ionic conductivity and high mechanical strength. An all-solid-state battery made with an approximately 10-μm-thick film shows good cyclability at 60 °C and no dendrite formation.
Eutectic Ga-In droplets can be functionalized with various polymers and co-polymers using atom transfer radical polymerization. The droplets are ready for direct solution processing to form liquid-metal nanocomposites for potential applications in soft robotics.
Gate reflectometry on an ancillary dot coupled to an electron reservoir is used to read the spin of a qubit in a CMOS device in a single shot with an average fidelity above 98% within 0.5 ms.
Light scattering spectra are acquired in the near field to map dipole–dipole interactions and extract all their vectorial components with 5-nm spatial resolution.
Metallic lithium wets a functionalized mesoporous carbon film to create a self-smoothing anode that, in conjunction with a standard lithium nickel–manganese–cobalt cathode, delivers long cycling life, 350 Wh kg−1 high-energy cells under realistic conditions.
Lithium transition metal oxide cathodes can degrade under high-voltage conditions by a redox mechanism by which oxygen vacancies form at the surface and migrate towards the bulk.
Embedding GaAs quantum dots in broadband photonic nanostructures allows a source of entangled photons to be fabricated with simultaneous enhancements of the most important parameters.
Current pulses of 105 A cm−2 can control the orientation of 100-nm-wide stripe domains in La0.67Sr0.33MnO3 and spin waves of 10 GHz can propagate along these domains with a group velocity of 2.6 km s−1.
Thermal diffusion of skyrmions in a non-flat energy landscape shows exponential temperature dependence and can be used for a reshuffler device with potential application in probabilistic computing.
While measurement of an electron spin commonly destroys it, the quantum non-demolition measurement implemented here for an electron spin qubit in a semiconductor quantum dot preserves the measured spin and allows for exponential suppression of readout errors by repeated measurements.
Ionic Coulomb blockade in nanochannels is shown to be a consequence of a second Wien effect, resulting from the dissociation of Bjerrum pairs that are formed under confinement.
A specifically designed family of synthetic lipids exhibits unique liquid-crystalline behaviour at low temperature, enabling maintenance of amorphous water down to about 10 K due to nanoconfinement.
Spin currents from an adjacent Pt layer can drive homochiral Néel domain walls in centrosymmetric rare-earth iron garnet films at more than 800 m s–1, taking advantage of the antiferromagnetic spin dynamics of the ferrimagnetic oxide.
MoS2 is shown to exhibit a stronger vdW interaction with graphite than with hexagon boron nitride, which is well described by Lifshitz theory and utilized to construct 2D heterostructures in a sophisticated way
