What do cosmetics, petroleum, and nanocatalysts have in common in light of SAXS?
Dra. Ana M. Percebom, Departamento de Química – PUC-Rio

Physical chemistry of colloids is a field where fundamental science often meets applications. We can transpose the knowledge of concepts and phenomena between different areas, such as cosmetics, oil production, catalysis, diagnostics, and displays. It has allowed our group to research different fields by comprehending phenomena at the nanoscale and their relationship with the macroscopic properties. For that, structural characterization of the colloids is essential, and Small-Angle X-ray Scattering (SAXS) has been a primary tool. This talk will show results that have elucidated various colloidal structures present in applications, making the correlation with the physicochemical properties possible. This understanding is vital for controlling the properties and transposing the knowledge between the different areas.
