Metallic nanowires can be sculpted out of semiconducting transition-metal dichalcogenide monolayers using focused electron-beam irradiation and have self-adaptive contacts to the semiconducting monolayers they are made from.
An in situ scanning transmission electron microscope can be used to follow and control the structural transformation between semiconducting and metallic phases in single-layered MoS2.
The bonding and activation of a molecule to a supported metal cluster catalyst can be controlled by using calixarene ligands to create a selective nanoscale environment at the metal surface.
Single amino acids and peptides can be identified by trapping the molecules between two electrodes that are coated with a layer of recognition molecules and measuring the electron tunnelling current across the junction.
Integration of diverse nanostructures allows the fabrication of a wearable system capable of storing data, performing diagnostics and delivering drugs.
