Brooks and Taylor structure
The structure of the anisotropic spheres which precipitate from isotropic pitch during pyrolysis. The structure of the spheres consists of a lamellar arrangement of aromatic molecules in parallel layers which are perpendicular to the polar axis of the sphere and which are perpendicular to the mesophase-isotropic phase interface.
The term Brooks and Taylor structure is recommended to describe the particular lamellar @MT07285@ of the spherules most commonly precipitated from pyrolysed @P04677@. The term honours the workers who first recognized the significance of @C00822@ to carbon science and technology and who first defined this spherical @MT07285@. The term Brooks and Taylor structure does not cover all structures found in the spherical @M03849@, because other lamellar arrangements have been observed.
