             abstract = "Diamond film grown on reticulated vitreous carbon (RVC), as a 
                         three dimensional composite, was investigated. RVC substrates were 
                         obtained at three different heat treatment temperatures (HTT) 
                         which promoted different structural organization indexes on their 
                         turbostratic carbon (TC) structure. Homogeneous microcrystalline 
                         (MCD) and nanocrystalline (NCD) diamond grains were formed and 
                         showed that are strongly affected by the substrate HTT. 
                         Particularly, the changes in diamond films properties were 
                         discussed as a function of the film nucleation and morphology 
                         evolution for growth times of 1 and 3 h. Scanning electron 
                         microscopy images confirmed the continuous films with high 
                         nucleation rate, including on RVC struts edges which actuality 
                         demand higher film growth rate. The high nucleation rate, typical 
                         of NCD formation in the first stage of film growth, was mainly 
                         attributed to the different graphitization indexes of such carbon 
                         substrates which were etched by atomic hydrogen on RVC prism or 
                         basal planes. Micro-Raman spectra also confirmed the features of 
                         NCD coating. The high contribution of NCD population in diamond 
                         Raman peak at 1332 cm(-1) promoted its asymmetry with some tailing 
                         towards lower wavelength shifts, better observed for diamond grown 
                         on RVC treated at 1300 K.",
