DESCRIPTION:Prof. Steve Eichhorn\, Bristol Composites Institute\, United K
 ingdom\nThis IMX seminar is co-sponsored by the National Center of Compet
 ence (NCCR) Bio-inspired Materials.\n\nThis talk will cover some work that
  we have been undertaking to better understand and utilise the interaction
 s of water with cellulose to produce composite materials. The hydrophobic 
 will be introduced through some work to explore the interactions between g
 raphene and cellulose. Modified celluloses will be introduced where we att
 empt to make what we term – amphiphilic cellulose – showing that hydro
 phobic interactions can be induced\, while also retaining the charge on na
 nocellulose. These forms of nanocelluloses are then incorporated into Pick
 ering emulsions\, whereby we use their water repellence to drive the inter
 action with so-called “hydrophobic” polymers. Along the way we will cr
 itique certain assumptions about hydrophobicity and show that really it al
 l boils down to dispersive effects. We will also hear about work where we 
 have addressed the redispersion of nanocellulose from the dried state\, us
 ing a facile liquid phase exchange approach. Finally\, some of our work in
  the fellowship addressing equity\, diversity and inclusion will be presen
 ted as a way to diversify science\, technology\, engineering and mathemati
 cs subjects through targeted programmes of work focussing on Black and Bla
 ck heritage staff and students. Some “forgotten” histories of Black sc
 ientists’ contributions to cellulose research will be uncovered along th
 e way.\n\nReference to 2 papers that are central / most important to your 
 talk. This helps students to prepare and dive into your subject deeper.\nE

  of Leeds\, graduating in 1993 followed by a Masters in Forestry and Paper
  Industries Technology at UMIST (1994). He then embarked on a PhD at UMIST
  in Paper Science\, graduating in 1999. Following this he had various acad
 emic appointments at the University of Manchester\, and left in 2011 for a
  Chair in Materials Science at University of Exeter. In 2017 he moved to t
 he University of Bristol where he is Chair Professor of Materials Science 
 and Engineering in the School of Civil\, Aerospace and Design Engineering.
  He currently holds an EPSRC funded Fellowship in Biobased Composites and 
 ED&I. In 2012 he won the Rosenhain Medal\, in 2017 the Hayashi Jisuke Priz
 e from the Cellulose Society of Japan and the Swinburne Medal in 2020.
