“…It is interesting to note, from Table I, that O~dv increases in the following fashion: 5CH3-1H-BTA > 1CH3-BTA > 1H-BTA. This order is reasonable with respect to the relative wetting properties (hydrophobic parameters) of organic substituents (27) and the proposed structure of the Cu-BTA complex (28). The suspected effect of surface roughness on the magnitude of | (29-31) could not be confirmed or denied, as we have no evidence that Cu surfaces used in this study have roughened.…”

The wetting characteristics of copper surfaces, with and without an exposure to benzotriazole and benzotriazole derivatives, have been investigated by dynamic contact angle measurements. The results were compared to corrosion rates measured on the same samples by electrochemical techniques. The experiments show that the inhibitor's effectiveness for corrosion reduction is not reflected well by the advancing contact angles of water. However, a good correlation is observed with the parameters obtained on a previously wetted surface, such as receding contact angles and the work of surface rewetting. These parameters were obtained through repeated dipping experiments. The details of the wetting process are evaluated quantitatively as an excess work of adhesion and can be used as an alternate measure of the expected corrosion resistance for differently treated surfaces. ) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.

“…Throughout the last thirty years, many different fabrication techniques have been explored in order to make high enhancement SERS substrates, including electrochemical oxidation reduction cycles (ORC) (Pemberton, 1991), chemical etching (Carron et al, 1991), metal island films (Schlegel and Cotton, 1991), electron beam lithography (Kahl et al, 1998), and nanosphere lithography (Jensen et al, 1999) to name a few. However, none of these techniques have been shown to produce large enough area, with high signal enhancement and uniformity that SERS substrates would be required for array techniques.…”

“…However, none of these techniques have been shown to produce large enough area, with high signal enhancement and uniformity that SERS substrates would be required for array techniques. They produce either relatively low enhancement and poor reproducibility but large surface area SERS substrates, such as ORC (Pemberton, 1991), chemical etching (Carron et al, 1991), metal island films (Schlegel and Cotton, 1991); or large enhancement but small area sample, such as electron beam lithography (Kahl et al, 1998) and nanosphere lithography (Jensen et al, 1999). Recently we have found that SERS substrates fabricated by oblique angle deposition (OAD) can provide extremely high SERS enhancement Chaney et al, 2005).…”

“…This method is also very effective for producing a Pt electrode of low surface area, for example, with a surface roughness factor down to 3 to 5, but with high SERS activity, however, the selection of the current and frequency are very different from those for Rh. Chemically etched electrodes In comparison with the ORC, a very simple tactic to roughen an electrode surface is chemical etching, which partially dissolves surface atoms by a chemical reaction with the solution [53]. This approach requires experimental skill to optimize the SERS activity for different metal samples.…”
