Employing potential-pH and cyclic voltammetric characterization techniques, Burke and coworkers [48, 73] have advanced the notion that incipient surface hydrous oxide species mediate the electrooxidation reactions of reducing agents of interest to electroless deposition. Thus, in the case of electroless Ni-B, an interfacial, basic, cationic Ni(I) hydrous oxide species would mediate the oxidation of DMAB, as shown in part here ... 

A voltammetric characterization of platinum single crystal surfaces produced by these three methods shows that a very similar surface order and cleanliness are obtained in each case. The features embodied by the third method which we use for the radio-electrochemistry work, are as follows ...

Figure 5.49 Time course for the limiting current at gold modified with the oligonucleotide 2/4 in methylviologen (MV+2) solution (0.1 mM in 0.1 NaCl) at an applied potential of 0 mV (vs. Ag/AgCl). The inset shows the time domain in which the electrode is alternatively exposed to and shielded from 346 nm illumination the arrows indicate when the shutter is open or closed. From R. S.

The effects of chloride and bromide are slightly different because of the lower adsorbability of these anions on the noble-metal surfaces. For example, bromide produces (3 x 3) and (4 x 4) structures, voltammetrically characterized on Pt(lll) by a sharp reversible spike denoting the rearrangement from 4/9 of ML to 7/16 of a ML [55]. It is interesting to note that in the case of a weaker interaction such as that of chloride on platinum, a diffuse structure can be advanced on Pt(lll), but an ordered structure can be obtained on Pt(100). Only when the anion concentration exceeds 10 mM, the Pt(lll) (3 x 3) ad-layer is found [56]. 

Size- and shape-controlled cubo-octahedral platinum(o) nanoparticles of 4nm average size stabilized by sodium polyacrylate showing 111 and 100 surfaces were used to prepare Vulcan supported electrocatalysts. Cyclic voltammetric CO oxidation studies carried out by the thin film rotating disc method show two different sites of CO oxidation (Fig. 2.19). This can be assigned to differences in the activity of the crystal surfaces and is in agreement with single crystal studies. TEM results after cyclic voltammetric characterization show a complete absence of agglomerations.

Electrochemical Control and Reflectance, Emittance and Solar Absorptance Measurements A Princeton Applied Research (PARC) Model 263 potentiostat with PARC s 270/250 software w used for preliminary voltammetric characterization and to control devices for spectral measurements. In-situ (i.e. as a function of applied potential) Specular IR (16° incidence). Diffuse IR, and Diffuse UV-Vis-NIR (0.2 to 1.1 pm) reflectance measurements were carried out, respectively, on a Perkin-Elmer (P-E) Model 1615 FTIR, a Bio-Rad FTS 6000 FTIR and a P-E Model Lambda 12. Vendor-supplied mirrors or Au surfaces, as appropriate, were used as references. In-situ emittance and solar absorptance measurements were carried out, respectively, on an A-Z Tek Model Temp lOOOA emissometer (2.5 to 45 pm range) and a Gier-Dunkle Emissometer Solar Absorptometer (0.3 to 2.5 pm range). 

One of the advantages of electrochemical detection is that voltammetric characterization can be used along with migration time for conclusive identification of compounds. This can be accomplished either by injecting the sample several times at different detection potentials or by using voltammetric detection. The small sample requirements make the first approach possible because only a...
