The issue of ohmic contact in WSe2 has been effectively addressed through a significant charge transfer mechanism enabled by the RuCl3/WSe2 heterostructure.
Light extraction is a key factor determining the efficiency of light-emitting diodes. This becomes more pronounced in high-refractive-index perovskite light-emitting diodes according to the ray-optics model. Photon recycling and microcavity effect are important ways to break through the ray-optics efficiency limit. However, these two effects are competing, that is, strategies to optimize them are mutually exclusive. For a breakthrough in efficiency, we should favour one of them and inhibit the other.
The fabrication of a molecular quantum sensor on the tip of a scanning tunnelling microscope enables the detection of minute magnetic and electric fields of single atoms with sub-angstrom resolution.
γδ T cell-based immunotherapies are limited by the reduced expansion and activation of the T cells ex vivo. Here the authors show that garlic nanoparticles can activate IFNγ-producing γδ T cells directly in the intestine, before they translocate to extraintestinal tumours, where they can synergize with anti-PD-L1 therapy, inducing robust antitumour immunity.
By utilizing the van der Waals electron acceptor α-RuCl3, this study establishes a p-type connection with WSe2, facilitating a high hole mobility of 80,000 cm2 V–1 s–1 for investigating quantum transport properties in a magnetic field of over 30 T.
Control of magnetization is at the core of many spintronic applications. Out-of-plane anti-damping magnon torque now enables low-power, deterministic switching of perpendicular magnetization at zero magnetic field.
Monolayer graphene in the quantum Hall regime exhibits a third-order nonlinear Hall response, which is robust against variations in magnetic field and temperature and provides insights into the interaction of chiral edge states.
Monolithic 3D integration of complementary WSe2 FETs has been achieved, featuring n-type FETs in tier 1 and p-type FETs in tier 2. Dense vias are realized using a pitch of less than 1 µm, facilitating 3D inverters as well as NAND and NOR logic functionalities.
Blood cancers generally derive from the bone marrow but there are no current targeted treatments. Here the authors present a bone-marrow-targeting nanoparticle that can bind and pull together tumour and natural killer cells for selective elimination of cancer cells, offering a strategy for the treatment of haematologic cancers.
Large-volume high-resolution X-ray nanotomography is used to identify topological defects emerging in a self-assembled triblock terpolymer single-diamond network.
Exosome targeting for therapeutic needs remains a challenge. Here, the authors show that ferromagnetic-nanotube-passivated exosomes promote the transition of proinflammatory macrophages to an anti-inflammatory state and myogenic maturation of dystrophic muscle progenitors in a murine model.
In Bi2O2Se thin films, the local inversion-symmetry breaking in two sectors of the [Bi2O2]2+ layer yields opposite Rashba spin polarizations, which compensate each other and give rise to the hidden Rashba effect. Hence, the films exhibit only even-integer quantum Hall states, but there is no sign of odd-integer states.
We present a Focus issue on how the research community is continually pushing the device performance boundaries of 2D transistors and explore the pivotal role that these devices play in the future computing landscape.
Gouty arthritis is an inflammatory arthritis characterized by high urate levels in the joints that is difficult to treat using standard therapies. Here the authors present a nano-enabled strategy that combines multiple lines of treatment for simultaneous reduction of urate levels and inflammation.
Astrocytes respond to electrical stimulation via diverse calcium signalling dynamics, which are important to maintain brain function. The tunable properties of graphene oxide-based electrodes can selectively trigger these calcium signalling responses.
The upstream self-diffusion of dissociated protons induces long-lasting electricity generation in 2D nanochannels of MXene/PVA film with low water permeability.
