Majorana modes are highly non-local quantum states with non-Abelian exchange statistics, which localize at the two ends of finite-size 1D topological superconductors of sufficient length. By precisely positioning magnetic atoms on a superconducting surface, their interaction is tailored such that the precursors of Majorana modes are simultaneously observed on both ends of linear atomic chains.
A solvent-free and zero-waste method was reported for the synthesis of single-atom catalysts via abrading bulk metal into single atoms. This strategy works for different metals (iron, cobalt, nickel and copper or their alloys) and supports (carbons, oxides or nitrides).
A growth strategy based on surface-accumulated excess electrons enables the realization of non-oxidized bare copper nanoparticles stable under ambient conditions.
The extent to which mRNA delivery, as well as the cellular response to mRNA drug delivery vehicles, is conserved across species in vivo is unknown. Using species-independent DNA barcoding, the authors measure delivery in humanized, primatized and normal mice, and identify a potential mechanism driving species-dependent lipid nanoparticle delivery.
Graphene has a centrosymmetric crystal symmetry, which prohibits second-order effects in transport experiments. Yet, giant second-order nonlinear transports can emerge in graphene moiré superlattices at zero magnetic field, originating from the skew scattering of chiral Bloch electrons in the superlattice and giving rise to both longitudinal and transverse nonlinear conductivities under time-reversal symmetry.
A non-destructive soft-lock drawing method can achieve carbon nanotube arrays with ultraclean surfaces and a very high degree of alignment. Such arrays could be used as nano-sized electrical contacts of high-density monolayer MoS2 transistors.
Hybrid single-electron turnstiles are candidates as a standard for the ampere expressing it with elegant simplicity. Yet, such devices may serve as a standard for the watt with similar elegance and simplicity.
The uptake and transfer of nanoplastics in the roots and shoots of lettuce and wheat were quantified by doping polystyrene nanoparticles with Eu–β-diketonate and using inductively coupled plasma mass spectrometry, time-gated luminescence and scanning electron microscopy.
A cryo-strain device capable of applying large, continuous strains to two-dimensional materials in situ enables the reversible tuning of magnetic order and spin-canting process of the layered magnetic semiconductor CrSBr.
Rhombohedral stacking of two identical non-ferroelectric monolayer transition metal dichalcogenides enables the observation of interfacial ferroelectricity.
Orally delivered rapamycin is an immunosuppressant that inhibits islet graft rejection in patients treated for type 1 diabetes, but it suffers from poor bioavailability, inconsistent cellular distribution and adverse reactions. Here the authors show that subcutaneous delivery of rapamycin using a polymersome platform allows for control of the drug’s biodistribution and activity on specific immune cells, which changes its mechanism of action from immunosuppression to tolerance, reduces side effects and enhances anti-inflammatory efficacy.
