The ability to control phase separation in molecular media (including metals, ceramics, minerals and polymers) is a conserved motif for designing mesostructured materials that spans antiquity, modern technology and the natural world. In particular, sophisticated quenching and annealing strategies to create bicontinuous or hierarchical morphology have allowed for the creation of materials with...

Deep eutectic solvents (DES) have attracted a wide interest as alternatives to traditional solvents due to their green character and potential designability of the solvent properties. DES show a melting point near or below room temperature with a relatively low vapour pressure, high thermal and chemical stability and wider liquid temperature range than molecular solvents. Furthermore they are...

Soft and deformable ionic microgels such as poly(N-isopropyl-acrylamide) co-acrylic acid (PNIPAM-co-AA) microgels have shown to be well suited as model systems to study the phase behaviour found for particles interacting via a soft isotropic potential. Additionally, subjecting these particles to an alternating electric field induces a dipolar contribution to the interaction potential, which...

Polymers show very interesting flow properties with increasing deformation related to changes of the storage and loss moduli. Ideally, these macroscopically observable changes can be linked to the microscopic structure and dynamics. Getting a direct handle on the microscopic quantities is challenging since scattering experiments on in-situ sheared polymers are difficult. We have constructed a...

A model for foods is to consider them in terms of colloidal composites. Great progress has been made in understanding colloidal systems and their interfaces using x-ray and neutron scattering but especially with contrast variation of one or both of the components. For colloids, the interactions between the components are relatively weak electrostatic and van der Waals forces. Even the major...

The di-saccharide trehalose has been the focus of a lot of research during the past two decades due to its superior ability to stabilize biological macromolecules in extreme conditions. A more fundamental understanding of the molecular properties of trehalose in solutions may lead to improved preservation techniques, such as improved food and medication storage, or successful cryopreservation...

We present a robust framework for pinpointing patchy intermolecular interactions from scattering data. Our analysis is based on a SAXS/SLS study of the milk protein lactoferrin which forms highly stereo-specific dimers, resulting in a non-monotonic dependence of the second virial coefficient on electrolyte concentration.
The results are interpreted using an integral equation theory that...

Understanding the mechanisms of deformation and failure in rocks and their implications for fluid-flow and -storage are key to a number of important industrial/environmental applications, including geologic CO$_2$ sequestration and hydrocarbon production. The common method to analyse the deformation behaviour of rocks is triaxial compression testing where an axial load is applied to a sample...
