1. 1. Self Assembly of Hardwood Xylan -In Aqueous Solution and at Cellulosic Surfaces

   Författare :Peter Westbye; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Solution properties.; Unbounded Lignin; Extraction; Harwood; Model Cellulose; Fractionation; Glucuronoxylan; Adsorption; Lignin Carbohydrate complexes; Agglomeration; Bonded Lignin;

   Sammanfattning : 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. LÄS MER

3. 2. Assembly characteristics of xylan rich extracts from birch

   Författare :Peter Westbye; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Xylan; Cellulose fibres; Adsorption; glucuronoxylan; Extraction; Aggregates; Solution properties;

   Sammanfattning : The greenhouse effect is one of the most important environmental problems that mankind has to solve. One solution could be the utilization of biomass to create new materials and fuels. Traditionally wood has been used as timber and as a raw material for pulp and paper production. LÄS MER

   Sammanfattning : The hemicellulose glucuronoxylan (GX) is the second most abundant polysaccharide after cellulose in the secondary cell walls of angiosperms and contributes significantly to the properties of wood as raw materials. Despite this, very little is known about the biosynthesis of hemicellulose. LÄS MER

7. 5. Effects of Molecular Architecture of Xylans on Material Properties

   Författare :Maria Gröndahl; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Xylans are among the most abundant polymers on earth. Nature has created xylans with different molecular structures in different plant species. This molecular architecture is not a coincidence but is tailored to create a particular desirable functionality. LÄS MER
