16. CONTROLLED ASSEMBLY AND FUNCTIONALISATION OF CELLULOSE-BASED MATERIALS
Abstract : The environmental effects caused by the use of fossil-based resources have intensified and driven society and research towards new materials and processes that utilise renewable resources. Within the development of new materials, wood has been identified as a raw-material from which high performing materials can be derived. READ MORE

17. Integrated Cellulosic Wood Aerogel Structures
Abstract : Highly porous aerogels based on renewable materials that possess structural functionality are appealing for sustainable energy regulation and harvesting. Achieving structural anisotropy provides advantageous directional diffusion and mechanical strength, however, introduces great engineering challenges, such as complex, costly, and time-consuming processing.

18. High Clay Content Cellulose Nanocomposites for Mechanical Performance and Fire Retardancy
Abstract : Materials based on wood can offer sustainable alternatives to fossil-based plastics and composites, and show interesting mechanical properties. However, the issue of their flammability is generally unresolved. In this thesis, eco-friendly, fire retardant clay-cellulose nanofibril materials are investigated. READ MORE

19. Biocomposites Based on Core-Shell Cellulose Nanofibers : Preparation, Structure, and Properties
Abstract : Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. READ MORE

20. Study of Paper Dry Strength Additives on Cellulose Fibres
Abstract : Paper packaging is commonly found in the form of paper and cardboard boxes, but recently paper packing is being used in food packaging, trays, beverage packaging and even paper straws, among others. Paper strength additives have been developed to increase the efficiency of the joint strength and the joint areas and potentially maintain bulk in paper products. READ MORE
