1. Chemical modification of cellulose-new possibilities of some classical routes
Sammanfattning : Owning to its unique structure, along with the inexhaustible renewability, cellulose has been a subject of scientific and commercial interest for over 150 years. However, given attractive structural properties, such as stiffness, hydrophilicity, stereoregularity, potential for chemical modifications and ability to form superstructures, utilization of this biopolymer is far below its potential.

2. Chemical Functionalization and Characterization of Cellulosic Materials
Sammanfattning : Polysaccharides are the most abundant biopolymers produced in nature and belong, together with proteins and nucleic acids, to the main components of life. Polysaccharides are polyhydroxylic polymers that can be functionalized by a wide selection of chemical reactions, and modifications of these biopolymers are applicable in the development of new materials.

3. Adsorption of xylans on cellulosic fibres -Influence of xylan composition on adsorption characteristics and kraft pulp properties
Sammanfattning : Xylans are polysaccharides present in large amounts in cell walls of vascular plants. They possess an inherent affinity to cellulose and will thus adsorb irreversibly on cellulose surfaces. LÄS MER
4. Novel strategies to increase throughput and differentiate lipid isomers in mass spectrometry imaging : Development of computational tools and complex mass spectrometric methods for nanospray desorption electrospray ionization
Sammanfattning : In this thesis, method development for improved analyte identification and throughput in mass spectrometry imaging (MSI) is discussed. In MSI, the spatial distribution of analytes from a sample is determined and visualized, information about the detected molecules interaction within the sample can thereby the deduced. LÄS MER
