Kinetically pumped avalanche multiplication has been demonstrated in a colloidal quantum dot photodetector, achieving an 85-fold multiplication gain. This proposes new opportunities for developing colloidal quantum dot single-photon detectors.

In a Mn₃Sn/W epitaxial bilayer, spin–orbit torque induces the coherent rotation of spins, which can couple to microwave currents. Unlike in ferromagnets, the resulting conversion of AC current to DC voltage remains robust at higher frequencies, which may facilitate the development of high-speed electronic devices.

This new β-Li₃N solid-state electrolyte demonstrates a vacancy-mediated superionic diffusion mechanism, achieving high ionic conductivity (2.14 × 10⁻³ S cm⁻¹) and effectively suppressing lithium dendrite growth. Its high compatibility with lithium and air stability promises improved safety and performance in all-solid-state lithium metal batteries, making it ideal for advanced energy storage applications.

Atomically intimate assembly of FeO_x-Rh-ZrO₂ dual interfaces by selectively architecting highly dispersed FeO_x on ultrafine raft-like Rh clusters supported on tetragonal zirconia enables highly efficient tandem conversion of syngas to ethanol.

By using scanning tunnelling microscopy and spectroscopy, researchers observe layer-dependent electronic correlations in rhombohedral graphene multilayers at 77 K, revealing the layer-enhanced low-energy flat bands and interlayer interactions.

Single-molecule electrical detections clarify both productive and hidden degenerate pathways of ring-closing metathesis, and enable precise on-device synthesis of a single polymer with single-monomer-insertion-event resolution.

This study reports a fully integrated 128 × 8 optoelectronic memristor array with Si complementary metal–oxide–semiconductor circuits, featuring configurable multi-mode functionality. It demonstrates diversified in-sensor computing tasks and consumes 20 times less energy than GPUs.

The study presents a modular DNA origami-based single-molecule nanosensor that separates sensing from the signal output. It achieves high fluorescence resonance energy transfer contrast and enables tuning of the response window for improved sensor specificity, multiplexing and logic sensing.

This study presents the development of nanodrugs based on bacterial-derived outer membrane vesicles for targeted intervention in nerve–cancer crosstalk, which efficiently enhances pancreatic cancer chemotherapy.

Low-toxicity ZnSe–ZnS core–shell quantum dots show tunable and stable blue lasing in solution.

Singlet–triplet qubits implemented in a 2 × 4 germanium quantum dot array allow for a quantum circuit that generates and distributes entanglement across the array with a remote Bell state fidelity of 75(2)% between the first and last qubit.

This study presents P-selectin-targeting mimic ligand-coated NIR-II-interacting gold nanoparticle-based superclusters as in vivo contrast agents for enhanced imaging of intravascular inflammation in a rodent model using optical coherence tomography.

Phages are known as human-safe nanosized viruses that specifically infect bacteria. This work shows that non-lytic filamentous phages displaying a PD-L1-binding peptide and a melanoma-targeting peptide can efficiently target tumours and inhibit tumour growth by blocking the immune checkpoint.

Scanning probe microscopy experiments realize the alternating-exchange spin-1/2 Heisenberg model via magnetic nanographene chains. They control odd- to even-Haldane phase transitions and monitor spin–spin correlations and triplon dispersion.

This work introduces a reaction system that enables the in situ conversion of H₂O₂ generated by 2e⁻ ORR at the self-cleaning electrode surface into alkaline-earth metal peroxides. The solid oxidizer CaO₂ exhibits comparable efficiency to H₂O₂ for tetracycline degradation.
