Bringing back the magic in metamaterials

A single drop of blood is teeming with microorganisms - imagine if we could see them, and even nanometer-sized viruses, with the naked eye. That's a real possibility with what scientists call a 'perfect lens'. The lens hasn't been created yet but it is a theoretical perfected optical lens made out of metamaterials, which are engineered to change the way the materials interact with light.

A most singular nano-imaging technique

Researchers have developed a new technique called SINGLE that provides the first atomic-scale images of colloidal nanoparticles. SINGLE, which stands for 3D Structure Identification of Nanoparticles by Graphene Liquid Cell Electron Microscopy, has been used to separately reconstruct the 3D structures of two individual platinum nanoparticles in solution.

Weyl points, a long-sought phenomenon, finally detected

Part of a 1929 prediction by physicist Hermann Weyl - of a kind of massless particle that features a singular point in its energy spectrum called the 'Weyl point' - has finally been confirmed by direct observation for the first time, says an international team of physicists.

New technique to synthesise nanostructured nanowires

Researchers have developed a new method for growing hybrid crystals at the nanoscale, in which quantum dots - essentially nanoscale semiconductors - of different materials can be sequentially incorporated into a host nanowire with perfect junctions between the components.
