Descripción
The European Spallation Source (ESS) is one of the largest science and technology infrastructure projects being built today. ESS will soon be the world’s most powerful source of neutrons, providing researchers with unique opportunities to explore the structure of materials at the atomic level. Neutron scattering at ESS will address critical questions in physics, chemistry, geology, materials science and life science. We are now inviting applications for a Postdoctoral Researcher in Small-Angle Neutron Scattering of Biocompatible Microgels. Small-angle neutron scattering (SANS) is a powerful technique for investigating the structure and dynamics of scientifically and technologically important soft and complex materials across nanometre-to-micrometre length scales. Energy materials, biomaterials, colloidal systems, and functional nanostructures are prime examples of systems whose properties and performance depend critically on hierarchical structures and processes occurring over these length scales. This project focuses on developing and characterising a new class of biocompatible thermoresponsive microgels for biomedical and soft matter applications. The work combines neutron scattering, rheology, advanced sample environments, and molecular simulations to understand how the internal structure and softness of poly(N-vinylcaprolactam) (PVCL) microgels influence their behaviour in dense suspensions and under flow. The goals are: Develop an understanding of the structure, mechanics, and flow behaviour of PVCL microgels Develop and implement a 1,2-shear cell for rheo-SANS and rheo-SAXS experiments at ESS and MAX IV, that will allow to measure scattered intensity in the velocity-gradient plane, the most sensitive to shear-induced deformations. Combine neutron scattering experiments with molecular simulations to establish predictive models for soft colloidal systems relevant to biomedical applications The Opportunity We are seeking an independent and highly motivated postdo
