Spatiotemporal thermoelectric microscopy enables the observation of electronic heat flow in graphene in diffusive and hydrodynamic regimes at room temperature, as well as a controlled transition from a Fermi liquid to Dirac fluid.
Measuring the gate capacitance serves as a probe of the correlated states in MoSe2/WS2 moiré superlattices, which can be further controlled via sample–gate coupling.
An optical analogue of magic-angle twisted graphene bilayer gives rise to rigorously stopped light, which coupled with gain allows for a new type of a nanolaser with remarkable figures of merit.
Optical spectroscopy can identify chiral indices of individual carbon nanotubes, but has so far been unable to determine their handedness because of the weak chiroptical signal. Rayleigh scattering circular dichroism now enables the identification of both chiral indices and handedness of individual nanotubes.
Despite its great potential, immune checkpoint blockade has shown efficacy in only a restricted number of patients. In this Article, the authors present a nano-based platform for the co-delivery of chemo- and immunotherapeutics that shows efficient synergic antitumour activity in large, hard-to-treat tumour models.
Almost all currently used vaccines against COVID-19 consist of either non-viral or viral nanoparticles. Here we attempt to understand the reasons behind the success of such advanced nanoscale vaccine technologies compared with clinically established conventional vaccines, and the lessons to be learnt from this potentially transformative development in the adoption and acceptance of nanotechnology for medicine.
Understanding the fundamental nano–bio interactions of nanomaterials intended for biomedical use might unlock potential alternative applications. Here the authors reveal a tumoricidal mechanism of black phosphorus nanomaterials where these nanomaterials directly affect the mitotic centrosome machinery by suppressing polo-like kinase 1, suggesting that nanomaterials can be applied in targeted cancer therapy with their intrinsic nano–bio properties.
Non-trivial topological magnetic textures, such as skyrmions, merons or vortices, possess topological charges Q with absolute values smaller or equal to one. Now, skyrmion bundles, multi-Q three-dimensional skyrmionic textures, are observed and their current-driven dynamics are studied.
A correlated structural and chemical evolution of silicon and the solid–electrolyte interphase was unveiled in three dimensions by integrating sensitive elemental tomography, an advanced algorithm and cryogenic scanning transmission electron microscopy.
Voltage control of magnetic order is one of the keys to energy-efficient spintronic applications. Voltage gating using a solid-state hydrogen pump now allows for reversible control of ferrimagnetic order, external-field-free 180° magnetic switching and ferrimagnetic spin texture writing.
Synergizing metal–support interactions and spatial confinement through atomic copper grippers boost the dynamics of highly loaded atomic nickel for high activity, high thermal/chemical stability and unprecedented coke inhibition in hydrogenation reactions.
Measuring the levels of circulating SARS-CoV-2 RNA in plasma might represent a more accurate way to detect lower respiratory tract and extrapulmonary infections, which classical COVID-19 detection assays based on nasopharyngeal swabs might miss. Here, the authors accurately detect SARS-CoV-2 RNA in plasma-circulating extracellular vesicles using a CRISPR–Cas-based strategy that shows promising characteristics for potential clinical application.
Optomechanical effects enable the realization of optical metavehicles that can be manoeuvred across a surface in plane-wave illumination and steered by incident polarization.
A droplet falling on a non-wetting plane is expected to randomly roll. Tang et al. uncover that by interfacing piezoelectric crystal plane, droplets self-propel in a furcated direction, a motility fuelled by cross-scale thermo-piezoelectric coupling.
The preparation of a diverse set of 2D materials and their co-integration in van der Waals heterostructures enable innovative material design and device engineering. This Review summarizes recent advances in 2D spintronics and opto-spintronics, the underlying physical concepts and future perspectives of the field.
Kinetics-controlled van der Waals epitaxy in the near-equilibrium limit by metal–organic chemical vapour deposition enables precise layer-by-layer stacking of dissimilar transition metal dichalcogenides.
