Small-angle neutron scattering experiments on nanostructured matter using contrast variation
- Journal Article
By means of small angle neutron scattering (SANS) two different kinds of nanocrystalline materials have been investigated. From the experiment one obtains information on particle size, size distributions, shape, porosity, and interparticle arrangement. By the additional use of contrast variation techniques it is possible to suppress parasitic scattering, e.g. scattering from pores that affects the results in a conventional SANS experiment. Furthermore, contrast variation allows for the specific labelling of a certain part of sample that is of special interest. In our study SANS experiments are presented on nanocrystalline Palladium (n-Pd) and inorganic colloidal dispersions (n-TiN), where the contrast variation serves as a tool to examine the interparticle arrangement and the shape of the sorrounding stabilising organic shell.
