1. Wettability of modified wood
Sammanfattning : Despite many excellent properties of wood which make it suitable for many applications, it suffers from a number of disadvantages limiting its use. For instance, modification is needed to reduce water sorption and to improve decay resistance, dimensional stability and weathering performance. LÄS MER
2. On the Adhesion Between Substrates Covered with Polyelectrolyte Multilayers
Sammanfattning : This thesis examines the formation of Polyelectrolyte Multilayers (PEM) on cellulose fibres as a new way of influencing the fibre surface and the adhesion between wood fibres. The aim of the study was to enhance the fundamental understanding of the adsorption mechanisms behind the formation of Polyelectrolyte Multilayers on cellulose fibres; to study how the properties of the layers can be influenced and to show how the properties of the layers influence the adhesion between the fibres and the strength of paper sheets made from the PEM treated fibres. LÄS MER
3. Formation and properties of polyelectrolyte multilayers on wood fibres : influence on paper strength and fibre wettability
Sammanfattning : The work in this licentiate thesis examines the adsorption of polyelectrolyte multilayers (PEM) onto wood fibres as a new way to influence the properties of the fibre surfaces and hence the fibres. Fundamental aspects of PEM formation on wood fibres have been studied, and discussed in terms of paper strength and wood fibre wettability. LÄS MER
4. Wetting and Capillary Flow of Surfactant Solutions and Inks
Sammanfattning : This thesis presents results of a series of experimental studies on the spreading dynamics of small drops of complex solutions on solid surfaces. The capillary flow dynamics of complex solutions have also been investigated. LÄS MER
5. Whey protein adsorption and aggregation on modified stainless steel surfaces in relation to fouling
Sammanfattning : This thesis focuses on the possibilities to reduce fouling by 1.Modifying the stainless steel surface. LÄS MER
