Trapped light orbits within an intriguing material

Light becomes trapped as it orbits within tiny granules of a crystalline material that has increasingly intrigued physicists, physicists have found.

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.

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.

Futuristic brain probe allows for wireless control of neurons

Scientists developed an ultra-thin, minimally invasive device for controlling brain cells with drugs and light.

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.

On the way to breaking the terahertz barrier for graphene nanoelectronics

Simple thermodynamics defines the performance of ultrafast graphene transistors and photodetectors.
