             abstract = "The nanocomposites of porous boron-doped diamond deposited on 
                         carbon nanotubes (BDD/CNTs) present great surface area and high 
                         capacitance, making them a material of considerable interest for 
                         application in electrochemistry. In this work, we present a new 
                         approach in which this nanocomposite is deposited on carbon fiber 
                         (CF) to increase the surface area and the capacitance comparing to 
                         the unsized CF electrode. We performed the dip-coating for 
                         catalyst deposition on CF surface. After, CNTs growth followed in 
                         a tubular reactor at 650 °C for 20 min, using camphor in a 200 g/L 
                         hexane solution as the carbon source. Electrostatic Self Assembly 
                         (ESA) seeding of nanodiamond (ND) went on by grafting polar groups 
                         onto CNTs surface by oxygen plasma functionalization. The seeding 
                         process was made with 4 nm diamond nanoparticles dispersed in KCl 
                         aqueous solution. The BDD films were deposited by Hot Filament 
                         Chemical Vapor Deposition (HFCVD) reactor. The authors studied the 
                         composites morphology, structure and electrochemical properties by 
                         Scanning Electron Microscopy with Field Emission Gun (FEG-SEM), 
                         Raman spectroscopy, cyclic voltammetry (CV) and electrochemical 
                         impedance spectroscopy (EIS). This new material presented larger 
                         surface area and higher capacitance compared to CF without 
                         treatment, as presented in electrochemical analysis results. The 
                         SEM micrographs showed absence of metallic particles on CNTs 
                         structure, what promoted a better quality diamond growth.",
