To develop and characterize filaments for advanced applications, i.e. green smart textiles or conductive fibers. Use a flow-focusing setup and cellulose nanofibers as a main material for preparation of filaments with high mechanical performance. To understand the fundamentals behind alignment and particle organization.To study impact of hydrolysis and delignification of wood chips on their structure and yield by in situ synchrotron experiments, such as SAXS, WAXS, Spectroscopy and others.
