The transition from an indirect to direct bandgap in transition metal dichalcogenides has been observed in samples with thicknesses ranging from 8 to 1 monolayers by angle-resolved photoemission spectroscopy.
Magnetic vortices can be nucleated and propagated in an extended film by tuning the attraction between them and the electrical nanocontacts deposited on the magnetic layer.
A study of the magnetic fine structure of the electronic states in a semiconductor quantum dot coupled to a superconducting contact highlights important elements that should be taken into account in the search for Majorana modes in the solid state.
The spin excitation energy and the magnetic anisotropy of individual atoms can be modified by varying the exchange coupling of the atomic spin to metallic leads.
A vaccine in which toxin antigens are non-disruptively detoxified by the use of nanoparticles provides improved efficacy and immunogenicity as compared with toxoid vaccines prepared from denaturation processes.
Rigid DNA origami scaffolds can be used to hierarchically organize metal nanoparticles, quantum dots and organic dyes into functional nanoclusters that have a planet–satellite-type structure.
A solid-state nanopore can be integrated with a graphene nanoribbon transistor to create a sensor that can detect DNA molecules using both the ionic current and the electrical current in the graphene nanoribbon.
A high-throughput optical imaging and spectroscopy technique has now been developed that characterizes the chirality and electronic structure of individual single-walled carbon nanotubes either on their growth substrate or in functional devices.
Kinesin motor proteins conjugated to DNA nanostructures can be used to assemble a network of microtubule tracks, and to control the loading, active concentration and unloading of cargo on this network, or trigger its disassembly.
