New unique test opportunities in bio-based materials at Max IV

​During 2020-2021, Chalmers will create new unique test opportunities for research in bio-based materials in the world-leading synchrotron facility Max IV. It is mainly research in the field of cellulose that will have better conditions than ever before.

MAX IVMax IV has the world's strongest synchrotron light, which creates entirely new conditions in the exploration of the innermost structure of materials. The facility was completed in Lund 2016 and has a large ring filled with fast electrons. By forcing them into magnets in a high-speed slalom path and in an extremely precise manner, x-rays are created, allowing one to see smaller components than usually possible. The x-rays are then directed into different beamlines depending on what you want to explore.

A flexible rheometric system for Cosaxs and Formax

At the Department of Industrial and Materials Science at Chalmers a modular and flexible rheometric system will be developed for the two beamlines Cosaxs and Formax. The purpose is to strengthen research and industry needs for the development of bio-based materials, especially from cellulose. Bio-based cellulose material is something that hopefully will replace much of the oil-based plastic that is manufactured today.


Flow behaviour in soft materials

Rheometry investigates the relationship between force and motion in semi-solid and liquid materials and how it affects the properties of the material. In soft materials, it is important to investigate the correlation between the molecular structure and the behavior of the material. The greater precision in how to predict the flow behavior of the material through rheometric models, the better the conditions for creating new materials with better properties.

​The Max IV in itself is set to provide unique scientific opportunities and we have the ambition to add to that several unique rheological testing options. We are dedicating our research and development efforts to make the system available to the general users, says Associate Professor Roland Kádár who will lead the development work at Chalmers.



The development work will be performed in the group of Associate Professor Roland Kádár in the Division of Engineering Materials at the Department of Industrial and Materials Science, in cooperation with scientists at the Department of Physics (Marianne Liebi, Aleksandar Matic) and Max IV (Kim Nygård and Ann Terry). 

The funding comes from Formax´-preproject and Chalmers Foundation
