Our society is today largely built by advanced materials with a large carbon footprint and a much longer life span than the items we make from them. In this talk, researcher Tomas Rosén will go through how we can use Nature’s own building blocks, so called cellulose nanofibers, to make new green sustainable materials.

The key is to build ordered structures from the nanofibers to control the material properties, and to do so in industrial processes. But how can we control the assembly of nanofibers? And how can we even have a clue of their behavior when they are only a few atoms wide? These are some of the questions that researchers seek answers to in the research conducted at synchrotron light facilities, such as MAX IV in Lund.

No registration. Welcome!

The lecture will be held in Swedish. The first 40 visitors will get a lunch wrap!

About the lecturer Tomas Rosén

Tomas Rosén received his Ph.D. in fluid mechanics at KTH in 2016. His thesis topic was on the dynamics of nonspherical particles in flows related to the production of biobased materials. He continued as a postdoc 2017-2019 at Stony Brook University, USA, where he focused on experimental characterization of flowing cellulose nanofiber systems using synchrotron X-ray scattering techniques. Since 2019, Tomas has been a researcher at the department of Fiber and Polymer Technology at KTH, where he continues his research on advanced characterization of processes including biobased nanomaterials.
