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.

Plasmonic nanopyramids change the shape of things to come in biomolecular delivery

Researchers are developing the next generation of gold microstructures, replacing the free-floating particle with pyramid-shaped gold structures anchored to a flat surface. These microstructures are more stable than traditional nanoparticles and focus laser energy into intense electromagnetic near fields.

Scientists develop new homoepitaxial graphene tunnel barrier/transport channel spintronic device

Scientists have created a new type of room-temperature tunnel device structure in which the tunnel barrier and transport channel are made of the same material, graphene. Such functionalized homoepitaxial structures provide an elegant approach for realization of graphene-based spintronic, or spin electronic, devices.

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.

Fullerene key to solving old astronomic riddle

Scientists were able to identify for the first time a molecule responsible for the absorption of starlight in space: the positively charged Buckminsterfullerene, or so-called football molecule.

Plantations of nanorods on carpets of graphene capture the Sun's energy

The Sun can be a better chemist, thanks to zinc oxide nanorod arrays grown on a graphene substrate and 'decorated' with dots of cadmium sulphide. In the presence of solar radiation, this combination of zero and one-dimensional semiconductor structures with two-dimensional graphene is a great catalyst for many chemical reactions.

A new way to treat and prevent acne through nanotechnology

New research identified that the nanoparticles were effective at killing Proprionobacterium acnes, the gram positive bacteria associated with acne, and even more importantly, they inhibited the damaging inflammation that result in the large, painful lesions associated with inflammatory acne.
