Long-term stability and aging of cellulose nanofibril dispersions

Cellulose nanofibrils (CNFs) are known to form associative structures even at very low concentrations; however, the fundamental mechanisms governing their assembly and the associated time scales remain poorly understood. Although significant research efforts are underway in this field, systematic, long-term investigations into the stability of CNF dispersions are still lacking. The aim of this project […]

Synchrotron Methods for Biomaterial Processes

TREESEARCH

Investigation into the small scale interaction of cellulosic nanofibrils with geling agents through diffusion in flow layers, and the study of the subsequent effect on macro scale flow behavior of fibre spinning. Methods primarily intended to be those utilized at synchrotron facilities, like USAX, WAXS, and more novel techniques like XMPI.

Cellulose-based organic solar cells via spray deposition

TREESEARCH

In this project, we use spray deposition to fabricate cellulose-based, flexible organic solar cells. We use TEMPO-cellulose nanofibrils (TEMPO-CNF) as sustainable substrate material, flexible silver- or copper-nanowires (AgNW-/CuNW) as electrode material, conductive poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) as electron blocking layer, and a mixture of poly(3 hexylthiophene) (P3HT) and [6,6]-phenyl C61 butyric acid methylester (PCBM) as

Conducting polymers-modified wood composites

TREESEARCH

In this project, we used different conducting polymers to impregnate the wood. Our goal is to create a pathway for studying the nano/microscopic structure of the conductive wood and the interactions between the wood components and the conducting polymer matrix. . In detail, we mainly focus on the difference of crystallinity and the orientation of
