Description
Adrian R. Rennie, Uppsala University, Sweden
Neutron scattering has particular value when it exploits the specific contrast available that provides distinct information about materials. The presentation will first highlight the specific advantages associated with the use of partially labelled molecules that can be used to identify chemical changes associated with just part of a molecule [1] and the clear extra structural resolution obtained when the relative arrangements parts of molecule can be determined [2]. The clarity of information from such measurements justifies the efforts required to make such samples. New data for colloidal particle mixtures will be shown that demonstrate the value of a wider range of deuterated materials. Some challenges associated with the preparation of other materials, for example colloidal particles will be described.
