Abstract:
Four experimental studies were performed in the previous period: Effect of protein adsorption on capacitance of water/nitrobenzene interface, Potentiometric study of fluorescent oxacyanine cation partitioning, frozen interfaces and microinterfaces. The most valuable experimental technique in use is impedance spectroscopy in the frequency range from 1 Hz to 65 kHz. Currently a new nonlinear least square software for data evaluation is being utilized. In the study of oxacyanine dyes, both experimental and computational potentiometry were used. The results provided more insight in interfacial potential behavior. The contribution was particularly significant in providing large set of data previously unpublished. Liquid/liquid microinterface is in its initial stage of investigation. The phenomenon similar to microelectrodes is clearly present, current work is aimed at reproducibility. Keywords: Liquid/liquid interface, Frozen electrolytes, Fluorescent dyes, Microinterfaces, Protein adsorption. (JES)
