21. Functionality of Spray-Dried Whey Protein Powders - Surface Composition, Particle Morphology and Rehydration
Sammanfattning : Whey protein powder functionality is expected to be closely linked to both structure and properties of the proteins. It is essential that whey protein powders are easily dispersed and dissolved in order to fulfil the specified nutrient content and the functionality in the final product. LÄS MER
22. From Responsive Interfaces to Honeycomb Membranes by Controlled Radical Polymerisation
Sammanfattning : In this study, surface modification of both organic and inorganic substrates (in terms of cellulose and silica nanoparticles, respectively) has been explored using surface-initiated atom transfer radical polymerisation (ATRP). The desire to modify bio-based materials to fit into new application areas and the need for bio-based materials with improved material properties is steadily increasing due to environmental concern.

23. Tuning Properties of Surfaces and Nanoscopic Objects using Dendronization and Controlled Polymerizations
Sammanfattning : In this study, dendronization and grafting via controlled polymerization techniques, atom transfer radical polymerization (ATRP) and ring-opening polymerization (ROP), have been explored. Modification of surfaces and cellulose using these techniques, which enable grafting of well-defined polymer architectures, has been investigated. LÄS MER
24. Sampling from large flotation cells : An invastigation of spatial distribution
Sammanfattning : The general trend in flotation technology today is towards larger flotation cells, which enables a higher throughput. However, adverse effects such as segregation and reduced froth transport efficiency have also been observed in larger cells. LÄS MER
25. Adsorption of surfactants and polymers on iron oxides : implications for flotation and agglomeration of iron ore
Sammanfattning : Iron ore pellets are an important refined product used as a raw material in the production of steel. In order to meet the requirements of the processes for iron production, the iron ore is upgraded in a number of steps including, among others, reverse flotation. LÄS MER
