                         substrate using Reticulated Vitreous Carbon (RVC) as an additional 
                         solid carbon source. RVC was produced at different heat treatment 
                         temperatures of 1300, 1500, and 2000 °C, resulting in samples with 
                         different turbostratic carbon organizations. The PS substrate was 
                         produced by an electrochemical method. NCD film was obtained by 
                         the chemical vapor infiltration/deposition process where a RVC 
                         piece was positioned just below the PS substrate. The PS and NCD 
                         samples were characterized by Field Emission Gun-Scanning Electron 
                         Microscopy (FEG-SEM). NCD films presented faceted nanograins with 
                         uniform surface texture covering all the pores resulting in an 
                         apparent micro honeycomb structure. Raman's spectra showed the D 
                         and G bands, as well as, the typical two shoulders at 1,150 and 
                         1,490 cm\−1 attributed to NCD. X-ray diffraction analyses 
                         showed the predominant (111) diamond orientation as well as the 
                         (220) and (311) peaks. The structural organization and the 
                         heteroatom presence on the RVC surface, analyzed from X-ray 
                         photoelectron spectroscopy, showed their significant influence on 
                         the NCD growth process. The hydrogen etching released, from RVC 
                         surface, associated to carbon and/or oxygen/nitrogen amounts led 
                         to different contributions for NCD growth.",
