“…Figure 1 shows voltammograms of 1 mM Ru(NH3)6 2+/3+ and 1 mM Fe 2+/3+ with the oxygen plasma untreated, patterned and entirely oxygen plasma treated ECR nano-carbon films. Since it is reported that the electron-transfer rates of Ru(NH3)6 2+/3+ are unaffected by the electrode surface, [9][10][11] the voltammograms were observed as a diffusion-limited reversible electrochemical response for all ECR nano-carbon electrodes, as shown in Fig. 1(A).…”

“…According to our observation, the water contact angle on an H-terminated surface gradually decreased at room temperature, probably because of the local oxidation to generate an inhomogeneous surface, or because of the contamination of the surface. The uniform oxidation of the diamond surface can be achieved by various processes, such as anodic polarization [8], treatment with oxygen plasma [9], treatment with thermally activated oxygen [10], UV irradiation in the presence of ozone [11], or treatment with acids [12][13][14].…”

“…Quanto aos materiais utilizados como substrato para deposição dos filmes de diamante e seu uso em aplicações eletroquímicas pode-se destacar o silício, o titânio e suas ligas. Embora com as desvantagens da baixa resistência mecânica, baixa condutividade elétrica e alto custo, o silício tem a vantagem de ser um material semicondutor e possuir coeficiente de dilatação próximo ao do diamante, o que o torna um dos substratos mais utilizados [12][13][14][15][16][17][18][19] . Por outro lado, um substrato que começou a ser visto com interesse pelos pesquisadores para este tipo de aplicação é o titânio [20][21][22] e suas ligas 23 .…”
