                         a productivity of 50g/(g(Ni) h) were grown by catalytic 
                         decomposition of a C2H6/H-2 mixture over a nickel (1 wt%) catalyst 
                         supported on graphite microfibers, which constitutes the 
                         macroscopic shape of the final C/C composite. The catalyst 
                         particle size and dispersion before CNF growth was characterized 
                         by high-resolution scanning electron microscopy (SEM). The 
                         resulting composite consisting of a weblike network of CNFs 
                         covering the starting catalyst was characterized by SEM and 
                         transmission electron microscopy to gain more insight into the 
                         relationship between the starting nickel catalyst particles and 
                         the as-grown CNFs. Apparently, CNF growth proceeds from different 
                         mechanisms: a base-growth mechanism, involving especially the 
                         large nickel particles; a tip-growth mechanism, involving mostly 
                         the smaller nickel particles; and a tip/octopus-growth mechanism 
                         (the most common), involving all particles. In all cases, 
                         restructuring of the nickel particle from a globular to a more 
                         faceted structure seems to be the key step in producing an 
                         extremely large quantity of CNFs with yields up to 100 wt%.",
