The adsorption of molecules to the surface of carbon nanostructures opens a new field of hybrid systems with distinct and controllable properties. We present a microscopic study of the optical absorption in carbon nanotubes functionalized with molecular spiropyran photoswitches. The switching process induces a change in the dipole moment leading to a significant coupling to the charge carriers ...

Anodic arc discharge supported by the erosion of the anode material is one of the most practical and efficient methods to synthesize various high-quality carbon nanostructures including nanotubes, graphene due to its relatively higher growth temperature and eco-friendly procedures. In order to increase the arc controllability of the as-synthesized products, we introduced a non-uniform magnetic ...

Thermal annealing of nanodiamonds with diameters of a few nanometers (in an inert atmosphere and at temperatures in the range: 1500-1800 °C) leads to the formation of carbon nano-onions (CNOs) with diameters between 5 and 6 nm, which correspond to nanostructures with six to eight graphitic layers. The resulting spherical CNO structures were thermally modified under different atmospheres and cha...

Germanium/carbon core–sheath nanostructures and junctions are produced when Ge nanowires are subject to a thermal treatment in an organic vapor doped vacuum. The organic molecules pyrolyze on the surface of the Ge nanowires and form a continuous graphitic coating. The carbon-sheathed Ge nanowires undergo melting and evaporation at high temperature, which results in the formation of germanium/ca...

In addition to carbon nanotubes, the production of noncarbon nanostructures has attracted much attention over the past few years. In particular, and due to their unusual geometry and promising physical properties, inorganic fullerene nanostructures have become one of the main focuses in nanoscale research since the first report of the synthesis of WS2 nanotubes in 1992. The synthesis of chalcog...
