Roland Kádár

Docent

The processing of soft matter into products typically involves rheologically complex fluids in complex flow configurations. Thus, understanding flow-field-matter/compositional interactions in relation to fundamental rheological properties is essential for obtaining products with favorable performance.

In this framework, the staples of Roland's research and current related activities and interests are:
(i) Advanced characterization methods, method development - focused on nonlinear material characterization and hyphenated rheological techniques, e.g. rheo-microscopy, rheo-SAXS, mainly applied to nanocellulose suspensions, polymer nanocomposites, adhesives and biomaterials (biofilms, tissues).
(ii) Tailoring multifunctional properties in nanostructured materials - focused on the process structuring of polymer nanocomposites based on graphene and other high aspect ratio fillers for enhanced electrical, antibacterial, thermal, mechanical, gas-barrier etc. properties.
(iii) Dynamics of simple and complex fluids for processing applications - focused on modeling, processing flow and compositional optimization of high filler content bicomposites and flow-assisted structuring of nanocrystalline cellulose dispersions.

Roland is PI in the Wallenberg Wood Science Centre (WWSC 2.0) and the Vinnova Competence Centre '2D material-based technology for industrial applications' (2D-TECH). Roland is also Reseach Competence Area leader for Predictive Processing within the FibRe Vinnova Competence Centre. In addition to his activities at Chalmers, Roland is President of the Nordic Rheology Society.​​

Welcome to 

2021_RK_Grouplogo.jpeg 
The word 'Rheology' in the logo above was created from experiments performed by lab members and friends, on the occasion of organizing the 28th Nordic Rheology Conference​Image credit (from left to right): RK, RK, Dr. Mina Fazilati, RK, Dr. Karolina Gaska and Dr. Santosh Pandit, Sahana Cooper, Yogesh Thadavathi.    

Our group is focused on Soft Matter research, specializing in rheology and processing thereof. We thrive on interdisciplinary cooperation and exciting new ideas are always welcome!

About the cover: Cellulose nanocrystals (CNCs) are 1D lyotropic nanoparticles that form a liquid-crystalline phases in water. This photo shows alignment of CNCs in a suspension, visualized by shear induced polarized light imaging combined with rheological characterization. It is one of the hyphenated rheo-methods for CNC characterization we discuss in this review.
