A process for the preparation of a catalyst for the production of carbon nanotubes, the use of the catalyst for the production of carbon nanotubes, and the carbon nanotubes obtained by this production process. The method comprises modulating source data to the data frame having a predetermined number of channel bits, determining merging bits and DSV based on the channel bits, and changing the predetermined number of the channel bits in the data frame based on the DSV and the merging bits. Another aspect of the present invention relates to use of said protecting groups in an orthogonal protecting group strategy for the synthesis of complex molecules that comprise a number of suitable functional groups. During this process, the support film provides added strength to the greensheet therein significantly reducing embossing and deformation of such greensheet. At the same time, said incoming programming is tested for matches in a TV ad database. The frame portion is made of a material having a higher light-shielding property than the middle portion.
