Epitaxial topological heterostructures of (Bi,Sb)2Te3/graphene/gallium have been achieved using molecular-beam epitaxy, providing the opportunity to access Majorana zero modes in electrical transport when combined with van der Waals tunnel junctions.
Scientists have realized Weyl modes by exposing a topological insulator to large magnetic fields. Their effort enriches the toolbox to design, engineer and manipulate topological materials for physics research and materials applications.
The arrangement of magnetic ions between layers of NbS2 affects it as though a giant magnetic field is applied in different directions for electrons moving with opposite velocities. This discovery goes beyond the reach of conventional magnets, and opens up the way to custom-made effective fields engineered to guide materials into new territory.
An artificial neuron architecture based on antiambipolar organic electrochemical transistors shows responses to biological ions and neurotransmitters akin to real neurons with comparable speed. The soft and more biocompatible nature of organic semiconductors could enable applications in brain–machine interfaces and in vivo sensing.
Using low-temperature scanning tunnelling microscopy on a MoSe2/few-layer graphene heterostructure enables localized exciton generation and mapping with atomic-scale spatial resolution.
A bioengineered model incorporating a synthetic extracellular matrix recapitulates the lymphoid tumour microenvironment, making it a valuable tool for drug testing and designing personalized therapies.
Time-dependent pump–probe studies of polaritonic transport — for polaritons formed by strong coupling between organic molecules and Bloch surface waves at the interface of a distributed Bragg reflector — reveal a transition between diffusive and ballistic behaviour.
A large-scale screening identifies an inhalable polymer nanoparticle formulation that safely and effectively delivers therapeutic mRNA molecules to the lungs of several animal species.
Targeting P-selectin enables safer and more effective nanomedicine delivery through caveolin-1-mediated endothelial transcytosis in preclinical medulloblastoma tumour models.
By exploiting optical phase-modulation at complex surface plasmon polariton patterns, as well as energy-filtered imaging, femtosecond electron pulses are dynamically shaped in phase and amplitude.
Soft actuators composed of a tough bioadhesive/elastomer shell encapsulating a stimuli-responsive metallic spring provide in situ mechanical stimulation of skeletal muscles to promote muscle tissue rehabilitation and prevent atrophy.
Two studies explore strongly correlated states of Bose–Fermi excitonic complexes realized in two distinct solid-state platforms, setting the stage for tabletop quantum simulators.
A new spectroscopic technique takes advantage of overlapping electronic bands to probe the strongly correlated states of magic-angle twisted trilayer graphene.
