found: Minerals as advanced materials II, 2012:p. 59 (The term "nanotube" does not have a clear-cut definition. In general understandings it describes a nanoscale tube-like structure which can be found naturally in some minerals or be man-made from a variety of materials. The majority of known nanotubes are still carbon nanotubes, but various types and structures of non-carbon nanotubes ... have also been synthesized)
