Thus began the subject of inorganic fullerene-like materials and nanotubes. Predictions made by these simulations are continually being confirmed as nanotube engineers find new ways to roll those sheets into tubes.
Several methods exist for the synthesis of inorganic nanotubes.
Each method may result in a different type, size and yield. The 'type' of tube refers to its atomic structure and chirality, 'Size' means the diameter and length of the tube and 'yield' refers to the purity of the product. As the diversity of available nanotubes increases, nanoscientists are gaining access to a wide variety of molecular columns, pipes, bearings and springs. The mechanical properties of these tubes are controllable by electronic means, making them ideal components for Nano-Electromechanical Systems, otherwise known as nanomachines . Two of the best understood inorganic nanotubes, Boron Nitride and Tungsten Disulfide, are described in more detail below.
