Rheo-PLI-SAXS supports research on self-healing battery materials
A MAX IV feature on self-healing battery electrolytes draws on our group's Rheo-PLI-SAXS setup and analysis. Our contribution was the multiscale rheo-optical/scattering method; the study was led by collaborators.
RheoMAXESS theme boosts rheometry applications at MAX IV
The LINXS RheoMAXESS theme, led by Roland Kádár, supports users and grows rheometry applications at MAX IV, building on techniques developed within the artSI initiative.
Rheo-PLI-SAXS featured as a science highlight in the MAX IV Annual Report 2025
The MAX IV Annual Report 2025 features our Rheo-PLI-SAXS platform in a full-page instrumentation highlight. Developed through a Chalmers–MAX IV collaboration and implemented at the CoSAXS and ForMAX beamlines, the technique combines rheology, polarised-light imaging, and small-angle X-ray scattering to study how alignment propagates across nano- and mesoscale in sheared hierarchical materials such as cellulose nanocrystals. The report notes strong cross-disciplinary interest in applying the platform, with continued development under the Advanced Rheological Testing Science Initiative (artSI) at MAX IV.

New method reveals how materials behave across multiple length scales
Chalmers and MAX IV present Rheo-PLI-SAXS — combining rheology, polarised-light imaging and small-angle X-ray scattering — to observe, simultaneously for the first time, how hierarchical materials orient across multiple length scales under flow.
RheoMAXESS science theme kicks off at LINXS
A new LINXS theme launched to grow rheometry applications at MAX IV, connecting the ESS and MAX IV science initiatives.
Our Rheo-PLI-SAXS capability listed among CoSAXS beamline capabilities, MAX IV Annual Report 2024
The MAX IV Annual Report 2024 lists advanced Rheo-SAXS combined with polarised-light imaging — developed with Roland Kádár at Chalmers — among the new capabilities of the CoSAXS beamline.
Invited speaker at SAS2024, Taiwan
Roland Kádár was an invited speaker at the International Small-Angle Scattering Conference (SAS2024) in Taiwan.
Battery-technology workshop at BITS, India
A STINT-funded workshop on electric-vehicle battery technology held at BITS, India.
Graphene spike mat and fridge-magnet technology to fight antibiotic resistance
A Chalmers feature on graphene 'spike mat' surfaces and magnetic-field ('fridge-magnet') alignment as strategies against antibiotic resistance.
Plenary at the 13th MTDM conference, Tokyo
Roland Kádár gave a plenary lecture at the 13th International Conference on Mechanics of Time-Dependent Materials in Tokyo; the next MTDM comes to Sweden in 2026.
Visiting researcher: Felix Ellwanger
Felix Ellwanger from the Karlsruhe Institute of Technology (KIT), Germany, is studying the flow behavior of protein–water mixtures in meat substitutes (twin-screw extrusion) during his research stay — probing shear viscosity, flow instabilities, and wall slip.
Visiting researcher: Matheus Mendes
Matheus Mendes, a visiting PhD student from the Federal University of ABC (UFABC), Brazil, joined us for a year-long stay to study the alignment of graphene nanoplatelets for conductive plastics and lightning-strike protection, in collaboration with Prof. Ragnar Larsson.
Our lab expansion is complete
We completed our lab expansion — more space for new testing equipment and a more efficient workflow, supporting the next chapter of our research.
Augmented-reality teaching featured by Chalmers
Chalmers featured our use of augmented reality in engineering teaching — turning 2D textbook machines into interactive 3D models students explore live and on their own devices, with promising early results. Related work on AR for teaching synchrotron science is in preparation.
New processing equipment courtesy of Wellspect Healthcare
Investment in research and education by Wellspect Healthcare — nearly a decade of close industry–academia cooperation (several projects, publications and two patents), most recently marked by a new Brabender 19/25D single-screw extruder placed in our lab.
