The transport of dissolved ions inside tiny carbon nanotubes apparently violates the famous Nernst–Einstein relation, which links diffusive and electric-field-driven motion.
An antiviral and antibacterial cotton textile based on a fundamentally different principle of incorporating copper ions into the cotton structure at the atomic level is fabricated with excellent air/water retainability and superior mechanical stability.
K+ ions in sub-1-nm-diameter carbon nanotube pores are found to disobey the Nernst–Einstein relation by three orders of magnitude. This behaviour results from drastically different mechanisms for ion diffusion and electromigration inside these channels.
A graphdiyne-assisted ultrafast sparking synthesis platform is developed to synthesize a group of metastable nanomaterials, including single-atom materials, high-entropy alloys and high-entropy oxides.
The interaction between distinct excitations in solids is of both fundamental interest and technological importance. The layered magnetic semiconductor CrSBr exhibits strong coupling between excitons and coherently hybridized magnons, where both magnetic fields and strain can tune the coupling precisely.
A single DNA or RNA duplex can rotate unidirectionally when subject to an external electric field, generating sufficient torque to power rotary motion of larger nanoscale objects.
Addressable DNA structures with lateral dimensions of ~2 µm can be self-assembled starting from over 1,000 distinct DNA-origami monomers via joint capture of the non-nearest neighbours.
Femtosecond electron diffraction and ab initio theory unravel ultrafast lattice dynamics in photoexcited two-dimensional heterostructures during charge transfer.
Measuring the in situ activation status of T cells is important to gauge the efficacy of immunotherapy approaches. In this Article the authors design a chemical probe that binds to the T cell membrane and scavenges reactive oxygen species (ROS), preventing ROS-driven T cell exhaustion while serving as a magnetic resonance imaging probe to quantify T cell activity in tumours and predict radiotherapy outcomes.
Spin manipulation for quantum information processing often requires cost-intensive sample design and cryogenic temperatures. Now, surface functionalization of CsPbBr3 quantum dots enables coherent optical manipulation of hole spins under ambient conditions.
A molecular catalyst supported on carbon nanotubes efficiently transforms the notorious water pollutant 1,2-dichloroethane into a useful chemical feedstock ethylene in an electrified membrane filtration device.
A non-destructive surface-enhanced-Raman-scattering-based nanoprobe detects multiple endogenous molecules in living plants that are released under either abiotic or biotic stress, indicating the possible onset of a disease.
Combining equilibrium self-assembly with coupling mechanisms defying Newton’s third law allows for the design of programmable, time-varying, self-organized assemblies mimicking living matter.
Scanning near-field optical microscopy measurements show that polaritonic nanophotonics is attainable in natural low-symmetry materials, leading to a general way to manipulate light at the nanoscale.
Using an ultrafast high‐sensitivity centred dark-field imaging approach, the picosecond-scale evolution of intrananoparticle vibrations can be directly mapped with a spatial resolution down to 3 nm.
