( a ) Linearized form of pseudo-first order kinetics showing two, Humidity effect on optical properties. (a) AFM image of CuPcTs film. The transition in C1 occurs in the same RH range (5070%) at which significant changes in optical constants, bandgap, and film thickness occur. Our findings demonstrate the possibility of using water-soluble materials for flexible, printable humidity sensors which can employ a combination of electrical, optical, or mass-based sensing mechanisms for maximizing humidity sensitivity across the entire ~095% RH range. Thus, even while the H2O-CuPcTs interaction most closely follows PSO kinetics due to multiple adsorption sites, useful information about the reaction kinetics is obtained by modeling the reaction as a series of sequential PFO reactions. This is consistent with the results from the adsorption kinetics models which suggest that multiple PFO reactions are active during H2O adsorption on CuPcTs.

Femtosecond laser 2008;8:7597. Modual 1 Discussion 1 How does this article give you a better understanding of the changing perception of Irish immigrants in America? We can determine that water had the highest solubility because it ran the quickest through the filter and had the lowest ++, value. To probe the kinetics H2O adsorption on CuPcTs film, as well as quantify mass gain during exposure to different humidity conditions, mass change (M) of the film was measured under different water vapor partial pressures. [4] Substituted phthalocyanine complexes often have much higher solubility. nines to grant solubility,1 in aqueous ambience in particular, e.g. performed spectroscopic ellipsometry experiments and modelling. 2d (bottom panel). This result, related to the behavior of n and k, is caused by dielectric screening of CuPcTs by water. Muckley, E.S., Jacobs, C.B., Vidal, K. et al. Gouterman, M. Spectra of porphyrins. 3c).
