A mesoporous material was studied with the SAXSpace system. Important structural parameters like pore size, degree of polydispersity, total volume fraction of the pores and arrangement of the pores were obtained.

Size and Size Distribution of Gold Nanoparticles by SAXS

Size and Size Distribution of Gold Nanoparticles by SAXS

Gold nanoparticle dispersions were measured with the SAXSpace system. SAXS proved to be a well-suited method for determining the size distribution of a binary mixture of two dispersions with very similar particle size.
