Surface interactions of s-triazine-type pesticides. An electrochemical impedance study

Article Abstract:

The study of the adsorption of s-triazine-type pesticides at ideally polarized electrochemical interface in the absence of specifically adsorbed halides is presented. The interfacial charge and the temperature determine which type of an adsorbed film is formed and the time-resolved impedance spectroscopy indicates slow changes within the film structure that becomes disordered and can be characterized in terms of the fractal geometry.

Protein interactions studied by SAXS: Effect of ionic strength and protein concentration for BSA in aqueous solutions

Article Abstract:

The samples of bovine serum albumin (BSA) solutions is studied with protein concentration, c, ranging from 2 to 500 mg/mL and ionic strength, I, from 0 to 2 M by small angle X-ray scattering (SAXS). The result obtained from the analysis shows that with the addition of salt, the protein interaction potential changes smoothly from a repulsive to an attractive potential.
