Extensional Flow-SANS Research Industrial Placement

Extensional Flow-SANS Research Industrial Placement

Within STFC, ISIS is a world-leading facility for scientific research using neutron scattering and muon spectroscopy, with a strong scientific user programme and extensive global links. We support a national and international community of more than 2000 scientists who are conducting research into subjects ranging from life sciences, clean energy, and the environment, through to nanotechnology, materials engineering, and IT, as well as fundamental physics and chemistry investigations.

The Small Angle Neutron Scattering (SANS) Group at ISIS operates four neutron scattering diffractometers in close collaboration with the Support Laboratories Group. The latter hosts a suite of facilities including chemistry, materials characterisation and biology laboratories for scientists to prepare and examine their samples complementarily to their SANS studies.

Amongst the characterisation facilities, rheology is an important technique to evaluate the flow and deformation of soft materials. The mechanical properties thus determined are a direct manifestation of the underlying structural changes, especially at the length scales of interest to SANS. Therefore, Flow-SANS studies are essential to investigate the structure-property relationships in soft materials. While we have established a portfolio of shear-flow-based SANS (standard rheometry, microfluidics, stopped-flow, capillary) at ISIS, the development of extensional flow-SANS has not been explored.

Thus, the goal of this project is to develop in-house capabilities to perform extensional Flow-SANS studies at ISIS with the available instrumentation. Different protocols, namely uniaxial extension, creep recovery/stress relaxation post extension, and dynamic mechanical analysis at a wide temperature window, can be explored. Coupled with SANS, one can obtain information about the molecular structure, branching, and morphological changes corresponding to macroscopic behaviour such as ductility, brittleness and buckling of soft solids. Such studies find relevance in various industrial operations ranging from polymer melt and composite processing, stability testing of biofilms/membranes and coatings, to performance testing of thin films in battery applications. The project offers a unique opportunity to combine two different fields of research, i.e. rheology and scattering, to address important performance aspects of soft materials. It is anticipated that the work will result in at least one peer-reviewed publication.

Brief overview of the scheme

STFC’s incredibly diverse range of placements allow you to work alongside world leading engineers, scientists and technicians in highly collaborative environments. Whichever you choose, you’ll become a critical member of the team in which you will be exposed to exciting projects and challenges from the start. You’ll be supported every step of the way by our dedicated Graduate Development Team who will also ensure you benefit from a range of personal development opportunities.

About the role and a summary of key duties & responsibilities

The work will include:

• Offline operation of the extensional accessory on the ISIS rheometer, and standardization of procedures. This includes optimization of sample conditioning, experimental protocols, and input/output variables.
• Commissioning and testing of the extensional rheometer on the ISIS TS2 SANS instruments. This deals with rheometer alignment, beam centering, instrument communication, and data interpretation.
• Specification of relevant sample preparation protocols for soft materials (polymers, colloids, biological systems, etc).

The project will be primarily carried out within the ISIS SANS group and will benefit from the expertise within the Soft Matter Section of the Sample Environment Group and the ISIS Laboratories. Full technical and scientific support will be provided to the student for the duration of the placement.
