Fullerene C60 in Aqueous Medium
Kocábová, Jana ; Gál, Miroslav ; Hromadová, Magdaléna ; Kavan, Ladislav ; Pospíšil, Lubomír ; Sokolová, Romana
The aqueous solution of C60 was investigated by electrochemical and spectroscopis methods such as UV-Vis, Raman, FTIR and AFM techniques. The association constants of fullerene-gamma-cyclodextrin complex and ,ethanofullerene conjugates with beta-cyclodextrins in aqueous solution were evaluated from the shifts of the formal redox potential of complexed and uncomplexed fullerene. The most suitable techniques for electrochemical characterization of fullerene derivatives proved to be the low-frequency phase-sensitive AC polarography and the steady-state voltammetry.

A curve template for I-V characteristics of the solar cells
Fejfar, Antonín
The contribution describes a computer program for manual fitting a theoretical dependence of the current flowing through a solar cell on the voltage in a way corresponding to flexible curve templates. The template provides handles "attached" to the curve for intuitive and independent manipulation of the parameters. This makes it possible to judge the sensitivity of the fit to the individual parameters.
