A simple soak for a solar tune-up

The performance of solar cells that consist of semiconductor nanoparticles surrounded by ligand molecules is now easier to control. Researchers from KAUST have developed a method that enhances the ability of these colloidal ...

Atoms placed precisely in silicon can act as quantum simulator

In a proof-of-principle experiment, researchers at UNSW Australia have demonstrated that a small group of individual atoms placed very precisely in silicon can act as a quantum simulator, mimicking nature - in this case, ...

Toward full exposure of 'active sites' for coaxial nanocables

Catalysts are of paramount importance to achieve high efficiency and economic profit for most heterogeneous reactions. Since catalytic reaction occurs only when reactants reach the active sites, these active sites must be ...

Moving silicon atoms in graphene with atomic precision

Richard Feynman famously posed the question in 1959: is it possible to see and manipulate individual atoms in materials? For a time his vision seemed more science fiction than science, but starting with groundbreaking experiments ...
