1. Tailoring Cellulose Nanofibrils for Advanced Materials
Sammanfattning : Cellulose nanofibrils (CNFs) are nanoscale fibers of high aspect ratio that can be isolated from a wide variety of cellulosic sources, including wood and bacterial cellulose. With high strength despite of their low density, CNFs are a promising renewable building block for the preparation of nanostructured materials and composites. LÄS MER
2. Two-dimensional Nanocomposites Based on Cellulose Nanofibrils and Graphene Oxide
Sammanfattning : Two-dimensional (2D) nanocomposites based on cellulose nanofibrils (CNF) and 2D nanomaterials are of interest as sustainable materials combining functional and structural properties. To achieve reinforcement effects from 2D nanomaterials, their orientation and dispersion state in the CNF matrix are important. LÄS MER
3. Orientation of elongated, macro and nano-sized particles in macroscopic flows
Sammanfattning : Non-spherical particles are present all around us, in biological, industrial and environmental processes. Making predictions of their impact on us and systems in our vicinity can make life better for everyone here on earth. LÄS MER
4. Functional Nanocellulose–Tannin Materials Inspired by Nature and Traditional Processes
Sammanfattning : Renewable and biodegradable alternatives to fossil-based materials are essential as concerns over depleting finite resources and the pollution of our ecosystems are growing. Abundant, highly anisotropic, and mechanically strong cellulose nanofibrils (CNF) are attractive building blocks for the fabrication of high-performance biobased materials that can compete with their conventional fossil-based counterparts.
