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.
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.
In contrast to the classical streaming potential relying on downstream ionic diffusion, an upstream proton diffusion within two-dimensional nanochannels is found to continuously generate electricity, advancing hydrovoltaic technology.
Not only electrons but also phonons can transport angular momentum in solids. Now, in an artificial superlattice, ultrafast demagnetization induces transfer of angular momentum from the spin system to the lattice.
Electrical stimulation of astrocytes using electrodes coated with graphene oxide and reduced graphene oxide can be used to trigger specific calcium signals.
Selective and quasi-continuous ferroelectric switching has been successfully implemented in devices based on topological Chern insulators, enabling the realization of 1,280 ferroelectric states for a proof-of-concept demonstration in noise-immune neuromorphic computing.
This work reports core–shell photovoltaic nanocells to enhance the photoresponse of the active layer and realize photolithographic manufacturing of large-scale-integrated organic phototransistors for high-resolution biomimetic vision.
Mirror twin boundaries in monolayer MoS2—line defects with reflection-mirroring symmetry—are one-dimensionally metallic. In this work, the authors fabricate these mirror twin boundary networks by epitaxity and incorporate them into ultrascaled 2D transistor circuits as gate electrodes.
An optimized design of free-space silicon nanoantennas combines high quality factor and low mode volume, reducing the trade-off between these parameters.
