Transport of micro-nano mass induced by laser on 1-D carriers

In order to explore the controllable transport of micro-nano mass in 1-D materials, a method that generate thermal gradient on carbon nanocoil by focused laser rays was adopted. Micro-nano paraffin transport process along thermally-induced carbon nanocoil irradiated by focused laser rays was analyzed experimentally and theoretically. The results show that when the laser is focused on the carbon nanocoil, the micro-nano paraffin sphere can be moved from the high temperature region to the low temperature region. The paraffin transport process in a single direction or in both directions along the carbon nanocoil can be controlled by changing the position of laser radiation. The mass and distance transported along carbon nanocoil can be controlled by adjusting the laser power. When the laser current is respectively 33.0 mA, 36.0 mA, 39.0 mA, and 42.0 mA, the transport distance of the micro-nano paraffin is 0.69 μm, 1.40 μm, 2.00 μm and 2.50 μm, respectively. These results present a new method for micro-nano mass transporting controllably on 1-D materials.
