Björn Sjöstrand

Björn Sjöstrand is a PhD student, with Licentiate Degree from 2017, in chemical engineering at Karlstad University. The main research focus on energy efficiency of paper manufacturing by understanding dewatering mechanisms.

Publications

Björn has published two scientific articles together with Christophe Barbier and Lars Nilsson, one about rewetting in Nordic Pulp and Paper Research Journal [1] and one about forming fabric structure in Tappi Journal [4]. Björn also presented research about forming fabric structure at Tappi PaperCon 2016 [2]. Björn has also published a licentiate thesis in early 2017 [3].
