26. Study of Paper Dry Strength Additives on Cellulose Fibres
Sammanfattning : 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. LÄS MER
27. Polymers in Aqueous Lubrication
Sammanfattning : The main objective of this thesis work was to gain understanding of the layer properties and polymer structures that were able to aid lubrication in aqueous media. To this end, three types of polyelectrolytes: a diblock copolymer, a train-of-brushes and two brush-with-anchor mucins have been utilized. LÄS MER
28. Exploring expandable microspheres as a novel pore former in gel-cast macroporous alumina
Sammanfattning : Expandable microspheres have been explored as sacrificial templates for the production of macroporous ceramics. Concentrated alumina powder suspensions that contain expandable microspheres have been consolidated by gel-casting. LÄS MER
29. Protein stabilization. Some methods and mechanisms
Sammanfattning : The effect of different additives on protein stability was studied, and the basis for stabilization was investigated at molecular level. The addition of sorbitol enhanced thermal stability of hen egg white lysozyme in aqueous solution. LÄS MER
30. On the phase behaviour of hydrogels : A theory of macroion-induced core/shell equilibrium
Sammanfattning : Colloidal macroions are known to interact very strongly with oppositely charged polyionic hydrogels. Sometimes this results in a non-uniform distribution of the macroions within the gel, a phenomenon that is not fully understood. LÄS MER
