Abstract
A few topics related with the latest mechanism of C60 formation during condensation of carbon vapor proposed by computer simulation of Irle/Morokuma group are introduced in an invited lecture of CAN'2011. Mysterious failure of the shrinking hot giant road mechanism in the last step was rationalized by low yield (0.001%) obtained in independent discovery of C60/C70 formed under identical conditions in a planetary nebula. Better yields (1–14%) obtained in carbon vapor experiments on earth were rationalized by taking the collision effect of inert atmospheric gas into account. Much higher yields (20–100%) from combustion method should come from a more positive role of the atmosphere, in this case combustion exhausts in the inner flame, if SHGR mechanism applies as well. Formation mechanism of carbon nano-onions is discussed.
