large-scale and elegant one-dimension tubular nanostructure TaS2, have been generated successfully employing solid-phase reaction growth with tantalum and sulfur powders. Detailed experimental procedures, and the characterization of associated product, have been evaluated using transmission electron microscopy (TEM) and other techniques. The results show that the reaction yielded a lot of one dimension nanostructures of TaS2 with average diameter of one hundred nanometers and length of several micrometers (or several ten micrometers). Moreover, effect of TaS2 nanostructure, as additive in commercial lubricating oil T40, was initially measured by UMT Multi-specimen Test System (UMT-2). The results show, as additive, antiwear and bearing weight ability of 1-D TaS2 nanostructure, excelled ordinary lubricating oil at atmosphere.
