Abstract

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.
 
Description This grant is ongoing, it concerns properties of amorphous solids built from colloidal particles, which are relevant in a range of contexts including food, and agri-chemicals. The project is joint with experimental teams at University of Bristol and ESPCI Paris. On the experimental side, there has been significant progress in developing new model systems and microscopy techniques, in order to characterise these materials, including the locations of individual (micron-sized) colloidal particles, and the forces between them. On the theoretical side, we have made significant progress with the characterisation of individual particle behaviour, including the associated stress tensor, which characterises internal forces within a material.
Exploitation Route Bayer are a partner in this project, they are mostly interested in controlling the properties of colloidal gels, for applications in agri-chemicals. Conversations with them are ongoing. Our new results for colloid science and stress characterisation also have wide potential applicability in the soft-matter community in academia.
