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 ...

The key to ion beams' polarisability

Polarisability determines the force with which an inhomogeneous external electric field acts on the ions of an ion beam. However, it can be quite tricky to obtain accurate values for this force. Now, two German theoretical ...

New family of tiny crystals glow bright in LED lights

(Phys.org) —Minuscule crystals that glow different colors may be the missing ingredient for white LED lighting that illuminates homes and offices as effectively as natural sunlight.

Dopants dramatically alter electronic structure of superconductor

Over the last quarter century, scientists have discovered a handful of materials that can be converted from magnetic insulators or metals into "superconductors" able to carry electrical current with no energy loss-an enormously ...
