“…Stoichiometric CdS is characterized by 77.8% of Cd and 22.2% of S. Therefore, from the results presented in Table 1, it can be concluded that all the preparation methods show about the same excess of S incorporated either by the solvent (DMSO), or as elemental S for the aqueous depositions. These results agree with the EDAX results already published for deposition method I11 (12,16).…”

. Heterojunctions of the type CdS/chloroaluminum phthalocyanine have been obtained by using the following methods to prepare the CdS layer: electrochemical deposition in dimethylsulfoxide (I); electrochemical aqueous deposition at constant reduction potential (11), or cyclic potential (111), or constant oxidation current (IV); and chemical aqueous deposition (V). The CdS films were characterized by SEM, EDAX, optical microscopy with Nomarski interference, X-ray diffraction, and photoelectrochemistry in polysulfide solution. The best cells show a conversion efficiency of about 0.2% under white light illumination of 90 mW ~m -~. They were obtained with a 1 . O Fm thick layer of the organic semiconductor and a 0.4 pm thick CdS film prepared by method I. This method yields a polycrystalline electrode characterized by large plates (1-3 pm) of tightly packed single oriented (1 11) cubic CdS crystallites showing low sub-bandgap absorption. The better performances of the CdS/CIAIPc heterojunctions obtained by method I can be understood in terms of absorbance of the CdS layer of optimum thickness, hole diffusion length in the CdS and electron-hole recombination efficiency at the CdS/ClAIPc interface.

“…Initial experiments focused on examining CdS films formed in a deposition cell similar to that used by Fatas et aZ. [7] We used alternating voltage cycles, and deposition times that had previously been shown by cyclic voltammetry to be sufficient for the electrolytic formation of low concentrations of S2-. [7] The basic setup for these depositions (referred to as BARE-AU), which were performed on a bare gold electrode (i.e., not modified with a S A M or an LB film) is indicated in Table 1 and in Figure 1A.…”

“…Electrolysis with a periodically varying current has been used in anodic dissolution, anodizing and corrosion processes [1]; electrodeposition [2,3] heating systems [4,5]; ohmic sterilization [6]; degradation of inorganic and organic pollutants such as NO and naphthalene [7][8][9][10] and in the synthesis and chemical isomerization of metal-organic complexes [11,12]. Recently, alternating current (AC) was used for the electrophoretic deposition (EPD) of biomolecules suspended in aqueous dispersions.…”

The change in the activity of glucose oxidase subjected to an asymmetrical alternating current (AC) electric field is investigated via horseradish peroxidase (HRP)-coupled bioassay. The effect of the amplitude, frequency and enzyme concentration have been shown to affect the enzyme activity towards glucose oxidation. The decrease in the enzyme activity is directly related to the change in pH and temperature of the GOx solution during AC electrolysis. The enzyme activity reduces with increasing amplitude, enzyme concentration and decreasing frequency. Results from UV-vis, FT-IR and UV CD spectroscopy showed that the AC treated GOx samples undergo structural modifications.
