ABOUT
Contrary to popular knowledge, most materials around us from foods, biological fluids, and adhesives, to cosmetics, concrete, paints, and polymers etc., whether natural or man-made, are neither simple fluids nor solids. Rather, their behaviour is a combination of both. The framework to study all such complex materials is Rheology, defined as the science of flow and deformation of matter. Due to the ubiquity of complex materials, rheology is a key ingredient for research in numerous scientific fields. Rheology is a truly interdisciplinary topic as it involves and is involved in physics, chemistry, biology, mathematics, geology, medicine, and engineering. Furthermore, rheology is uniquely positioned as the link between advances in soft matter science and industrial process operations.
The RheoMAXESS Theme is born out of early success in developing new rheo-SAXS/WAXS techniques at MAX IV and the strong drive for industrial collaborations around X-ray and neutron science in Sweden. The vision is to upscale the cooperation model, join focus with ESS, and galvanise a community around these two local unique strengths that will be capable of advancing soft matter science and technology and propel research around X-rays, neutrons, soft matter and rheology at MAX IV and ESS to a world-leading position.

Professor of Materials, Centre for Analysis and Synthesis, Department of Chemistry, Lund University, Sweden.
Karen and her research group focus on understanding the formation of functional hierarchically structured materials in order to apply that understanding to make new materials. They use self-assembly, driven by interactions between nanoscopic species (micelles, nanoparticles, polymers) in solution and at interfaces to form materials with organized structures from nm to cm. Understanding interactions between surfaces, nanoparticles and other species is central to our control over structure and thus function.
They use time-resolved grazing incidence X-ray & neutron reflectivity, liquid diffraction and small angle scattering to study formation mechanisms & final structures. A range of other complementary techniques (including TEM, SEM, AFM, NMR, light scattering, surface tension, conductivity, XRD, SESANS, USANS/USAXS, gas adsorption) are also used to characterise our materials across length scales from tens of Ångstroms to microns. Extensive collaborations with other groups in industry and academia apply the novel materials synthesised in our group to applications from delivery of active species, to catalysis and “green” gels or emulsions.

Postdoctoral Researcher at the Division of Glycoscience, KTH Royal Institute of Technology , Sweden.
Marjorie is a postdoctoral researcher at KTH working on cell bran. Ozriginally a Food Technologist working in Industry, she sought to broaden my horizons and pursued first an MSc in Food Science, and then a PhD also in Food Science, both at the University of Leeds UK. Her PhD focused on the crystallisation of cocoa butter primarily using X-ray scattering, NMR relaxometry, and DSC.
Her interest in X-rays led to a first postdoc/research position at Stockholms Universitet working on supercooled water and amorphous ices using X-ray scattering and XPCS techniques. Once more, X-rays led the way to her next position here at KTH where she is part of the glycoscience group and she is applying her X-ray knowledge, while learning some Biochemical tools.

WORKING GROUPS FOR RHEOMAXESS
RHEOMAXESS working group 1
Infrastructure development
The theme was born from a quest to develop new rheological sample environments for ESS and MAX IV. This working group will oversee the strategy for advancing the field, including the development of software packages for data analysis in conjunction to the theme. Data processing and interpretation is a recurrent issue for many users. The focus on advanced characterisation techniques will be scientifically opportune but it will inherently drive the need for dedicated data analysis routines.
RHEOMAXESS WORKING GROUP 2
Material development and processing
Rheology has many applications in terms of materials development. It both probes the structure of materials as well as how materials act during product manufacturing. The application range from food to sustainability, biomedicine, and energy. The working group will coordinate how we reach out to the different disciplines in order to use the developments of WG1 to advance the science in the respective fields.
RHEOMAXESS WORKING GROUP 3
Education and outreach
The working group will bring together WG1 and WG2 and organise events where we introduce academic and industrial partners to the scope of the theme. The aim is also to reach out to new partners and understand specific scientific needs that could be translated into new developments in WG1 and WG2.

Professor, Department of Industrial and Materials Science, Chalmers University of Technology, Sweden.
Roland and his group work in the general area of rheology and processing of soft matter. Current research revolves around (i) complex fluids flows, (ii) field-matter interaction in nanostructured fluids for multifunctional properties and (iii) advanced rheometry. (i) is mostly focused on processing applications and nonlinear phenomena in general (instabilities) ranging from polymer melt flows to thixotropic yield stress fluids in general. In (ii) we use flow and magnetic fields to tailor the structure of soft matter / materials containing nanofillers, for e.g. antibacterial applications. And through (iv) we create the means to understand (i) and (ii) through characterization methods such as developing novel rheo-SAXS (small-angle X-ray scattering) techniques at MAX IV, nonlinear mechanical spectroscopy, rheology combined with optics, dielectric spectroscopy, high pressure rheometry etc.
