Carbon nanotube research developments in terms of published papers and patents, synthesis and production

Progress of carbon nanotube (cnt) research and development in terms of published papers andpatents is reported. developments concerning cnt structures, synthesis, and major parameters, in termsof the published documents are surveyed. publication growth of cnts and related fields are analyzed forthe period of 20002010. from the explored search term, ``carbon nanotubes'', the total number of paperscontaining the cnt concept is 52,224, and for patents is 5,746, with a patent/paper ratio of 0.11. for cntresearch in the given period, an annual increase of 8.09% for paper and 8.68% for patents are resulted. pub-lished papers for cnt, cvd and ccvd synthesis parameters for the period of 20002010 are compared. inother research, publications for cnt laser synthesis, for the period of 20002010, are reviewed. publica-tions for major laser parameters in cnt synthesis for the period of 20002010 are described. the role oflanguage of the published references for cnt research for the period of 20002010 is also investigated.published papers/patents in english, japanese, chinese, russian, german, french, polish, and spanish lan-guages are compared. as expected, the number of paper/patent publications in english dominates otherlanguages.
