3D imaging of objects with details as small as 25 nanometers

Scientists have created 3D images of tiny objects showing details down to 25 nanometres. In addition to the shape, the scientists determined how particular chemical elements were distributed in their sample and whether these elements were in a chemical compound or in their pure state.

Fascinating quantum transport on a surface

Topological insulators are an exceptional group of materials. Their interior acts as an insulator, but the surface conducts electricity extremely well. Scientists now could measure this for the first time directly, with extremely high temporal resolution and at room temperature. In addition, they succeeded to influence the direction of the surface currents with a polarized laser beam.

Wrapping carbon nanotubes in polymers enhances their performance

Scientists developed a technique that 'exfoliates' aggregated clumps of CNTs and disperses them in solvents. It involves wrapping the tubes in a polymer using a bond that does not involve the sharing of electrons. The technique is called non-covalent polymer wrapping.

Nanoscale 'worms' provide new route to nano-necklace structures

Researchers have developed a novel technique for crafting nanometer-scale necklaces based on tiny star-like structures threaded onto a polymeric backbone. The technique could provide a new way to produce hybrid organic-inorganic shish kebab structures from semiconducting, magnetic, ferroelectric and other materials that may afford useful nanoscale properties.
