1. Self Assembly of Hardwood Xylan -In Aqueous Solution and at Cellulosic Surfaces
Abstract : The climate change on our planet is an issue of great concern. The dignity of this issue was confirmed by the award of the international panel of climate change (IPCC) the Nobel peace prize. This problem arises from the way that we live our lives, how we produce energy, materials and chemicals from a fossil source. READ MORE

2. Lignin polysaccharide networks in softwood and chemical pulps : characterisation, structure and reactivity
Abstract : The chemical interactions between the main wood components i.e., cellulose, hemicelluloses and lignin are of fundamental importance for understanding the chemical aspects of wood formation and its reactivity during fibre processing e.g during chemical pulping of wood. READ MORE

3. A biomimicking approach for hemicellulose processing
Abstract : Lignocellulose can become the best opportunity for the society to reduce its dependency on the harmful petroleum based products as well as to produce clean energy. In each part of the production cycle, biomass based products have a better environmental profiles than their petroleum based counterparts. READ MORE

4. Lignocellulose Degradation by Soil Micro-organisms
Abstract : Lignocellulosic biomass is a sustainable resource with abundant reserves. Compared to petroleum ‐ based products, the biomass ‐ derived polymers and chemicals give better environmental profiles. A lot of research interest is focused on understanding the lignocellulose structures. READ MORE

5. Mechanical Pulp. Effects of Pretreatment and Wood Source on Fiber Separation and Pulp Properties
Abstract : The work presented in this thesis concerns the mechanical pulping process and the effects of wood source and pretreatment conditions on the pulp properties. In the first part, the deformation of Norway spruce (Picea abies) wood samples was investigated under shear and torsional loading at different temperatures (20-95°C) and sulfonation conditions.
