Nanotechnologies. Terminology and definitions for nano-objects. Nanoparticle, nanofibre and nanoplate Ingestion-build-221493 Electrical apparatus for explosive gasAs many authorities predict that applications of nanotechnologies will pervade all areas of life and will enable dramatic advances to be realized in all areas of communication, health, manufacturing, materials, and knowledge based technologies, there is an obvious need to provide industry and research with suitable tools to aid the development and application of those technologies. It is also essential that regulators and health and environmental
