From a synthesis standpoint, nanotechnologies can be classified as variations of bottom-up technologies, such as self-assembly, or top-down technologies, such as lithographic methods (Box 1). Many nanotechnologies combine aspects of both strategies.
Posted on. (Answer #1). Nanochemicals are chemicals generated by using nanomaterials, materials which have size on nanometer dimensions. The nanochemicals are used in a variety of applications, including chemical warfare, bicycle manufacturing, armor design and military weapons.The most commonly used and studied nanochemical is carbon nanotubes, that are used extensively in industry for applications such as stronger materials (stronger bicycles).pecialized materials are designed to perform a specific task or function. Applications include electronic equipment (high purity silicon and germanium), machine tools (high tungsten high carbon steel), dental filling (dental amalgam), etc.
