16. Improved energy efficiency in double disc chip refining
Sammanfattning : The electrical energy consumption in thermomechanical pulping (TMP) is very high, in the range of 2 – 3 MWh/adt depending on process solution and on the product quality specifications for the paper product. Both pulpwood and energy prices have increased rapidly for some time. LÄS MER
17. Double Layer Forces: the Role of Molecular Solvents
Sammanfattning : The dielectric continuum model has rightfully been and continues to be a major workhorse for theory and modelling in Surface and Colloid Chemistry. Due to the implicit description of water, entering only as a scaling constant for charge-charge interactions, one would not expect it to work for short distances. LÄS MER
18. Low-Cost, Environmentally Friendly Electric Double-Layer Capacitors : Concept, Materials and Production
Sammanfattning : Today’s society is currently performing an exit from fossilfuel energy sources. The change to sustainable alternativesrequires inexpensive and environmentally friendly energy storagedevices. However, most current devices contain expensive,rare or toxic materials. These materials must be replaced bylow-cost, abundant, nontoxic components. LÄS MER
19. Double-contrast MRI for the staging of rectal carcinoma: Technical aspects and clinical experience
Sammanfattning : Aim of the study Today´s methods for the staging of rectal carcinoma: ultrasonography with transrectal probe, CT, MRI or MRI with a rectal coil, all have limitations. The aim was therefore to develop a new, double-contrast MRI method for evaluation of rectal carcinoma. LÄS MER
20. The self-spreading double bilayer/Advances in lipid membrane nanotechnology
Sammanfattning : In my thesis I describe the generation, characterization and uses of self-spreading double bilayers. This new type of solid-supported model membrane combines features and properties of the 2D lipid bilayer membrane, and the 3D phospholiposome. The double bilayer membrane, i.e. LÄS MER
