DESCRIPTION:Prof. Tanja Zimmermann\, Empa Materials Science and Technology
 \, ETHZ D-MATL and EPFL STI Materials faculty\nWithin the last twenty year
 s a tremendous progress has been made in the more eco-friendly production 
 of cellulose nanofibers (CNF)\, their chemical surface modification and us
 e as building blocks in dense\, soft\, and porous systems for the developm
 ent of functional materials. Depending on the envisaged application\, the 
 inherent properties of CNF such as e.g. biodegradability\, renewability\, 
 high surface area\, high strength and stiffness at low density\, or therma
 l expansion have been exploited for polymer composite\, paper and packagin
 g\, electronic\, filtering\, cosmetic\, automotive\, or bio-medical applic
 ations. Moreover\, emerging technologies like the direct ink writing or ot
 her 3D printing techniques have been more and more exploited for the produ
 ction of 3D architectures with CNF as building blocks. In this context the
  development of viscoelastic inks is of utmost importance. The shear-induc
 ed alignment of CNF leads to textured anisotropic materials where structur
 es and mechanical properties can be controlled.\nThe presentation will giv
 e an overview on cellulose based material developments at Empa in Switzerl
 and over the last two decades.\nBio: Tanja Zimmermann is Director of Empa 
 and Professor of Materials Science at ETH Zurich and EPF Lausanne. She rec
 eived her PhD from the University of Hamburg in 2007 for her research that
  provided the basis for technical applications of cellulose. Between 2001 
 and 2012\, she established the research field of cellulose nanocomposites 
 both at Empa and in Switzerland. From 2011 to 2017\, she was head of Empa'
 s laboratory for Applied Wood Materials\; since fall 2017\, she has been a
  member of the institute's directorate and head of the department Function
 al Materials with six research units dealing with a multitude of materials
 \, ranging from wood- and cellulose-based materials to concrete and asphal
 t\, high-performance ceramics and polymer fibers\, as well as materials an
 d components for energy applications. At the same time\, she took over the
  co-leadership of the Research Focus Area Sustainable Built Environment\, 
 in which topics such as circular economy\, resource efficiency and the suc
 cessful implementation of the Swiss energy strategy play a central role. I
 n the last three years\, she and her colleagues have also established comp
 uter- and data-based materials science and – in cooperation with the Imp
 erial College London – the Materials and Technology Centre of Robotics a
 t Empa.
