Maximum surface coverage acid

Protein adsorption to PS latex has also been determined by sedimentation field flow fractionation (SdFFF). The maximum surface coverages of P-casein and p-lactoglobulin on negatively charged PS latex calculated using this method were similar at around Img/m [19]. This figure, which was confirmed by amino acid analysis of the material irreversibly bound to the surface, was significantly lower... [Pg.759]

Maximum Surface Coverage of Various Carbons of Different Oxygen Contents by Stearic Acid Adsorbed from Carbon Tetracbloride Solution... [Pg.150]

For the purpose of demonstrating the effects of surface coverage by Pd, 0pd, on the rate of electro-oxidation of formic acid and the ORR, Fig. 8.17 reveals that the i versus 0Pd relationship again has a volcano-like form, with the maximum catalytic activity being exhibited for 1 ML of Pd. The examples that we have given indicate that volcano relationships are the rule rather than the exception, emphasizing the importance of a systematic evaluation of the catalyst factors that control catalytic activity. A thorough... [Pg.264]

LEED and CEELS Data. The Au(l 11) electrode prepared in UHV showed a broad, integral (1 x 1) spots, indicating a reconstruction of the surface into the Au(lll)-(1 X 23) structure (neither Pt(l 11) nor Rh(l 11) are subject to surface reconstruction in a broad temperature range) (47, 48, 50-53). After bisulfate adsorption on the Au(l 11) electrode and the electrode emersion of to UHV the measurements showed a weak Au(l 11)(V3 x V3)R30 LEED pattern (46). This pattern was observed only at the maximum adsorbate coverage. Equivalent LEED measurements for both Pt(l 11) and Rh(lll) produced sharp (V3 x V3)R30 LEED patterns. The corresponding, highly ordered (V3 x V3)R30 surface structures were obtained in a broad bulk concentration range of sulfuric acid. [Pg.133]
