Horseradish peroxidase adsorption on silica surfaces as an oscillatory dynamical behavior
Article Abstract:
A study reveals that the maintenance of horseradish peroxidase (HRP) on silica surfaces stems form a potential effect of adsorption on the dynamics of an oscillatory oxidation of NADH catalyzed by peroxidases. The relative change in the HRP concentration in solution will be most pronounced at low concentrations of the enzyme and high reactor surface-to-volume ratio.

Evidence for secondary minimum flocculation of Stober silica nanoparticles at the air-water interface: film balance investigations and computer simulations
Article Abstract:
The interactions of Stober silica nanospheres having diameters of ca. 40, 100, and 200 nm, floating at air-water interfaces was studied by using a Wilhelmy film balance and computer simulation. A computer simulation-assisted method is proposed to estimate the p-p distances determined from the pressure-area isotherms.

Network growth in the flocculation of concentrated colloidal silica dispersions
Article Abstract:
Salt-induced flocculation of concentrated colloidol silica dispersion in water was studied using small-angle X-ray scattering (SAXS) and oscillatory shear rheometry. Data showed progressive retardation of the flocculation process.
