6. Synthetic Paper for Point-of-Care Diagnostics : Capillary control, surface modifications, and their applications
Sammanfattning : Capillary-based platforms for diagnostics are popular for the point-of-care diagnostics market because of their low cost, easy fabrication, and easy operation. Lateral flow tests are an excellent example of capillary-based platforms for point-of-care diagnostics. LÄS MER
7. Properties of modified starches and their use in the surface treatment of paper
Sammanfattning : The papermaking industry uses a large amount of starch each year, both as a wet-end additive and as a rheological modifier in surface sizing and coating colors. It is important to be able to reduce the amount of chemicals used in the papermaking and surface treatment process, to reduce costs and to make the process even more efficient. LÄS MER
8. Towards an understanding of surface hydrophobization of paper - Exploring the effect of polymer nanoparticles, starch, ionic strength and process parameters
Sammanfattning : Paper materials are cost effective and lightweight, they can easily be recycled and their use as an alternative to plastics is advantageous from an environmental and sustainability perspective. However, competing with plastics for packaging applications is a challenge for cellulosic products. LÄS MER
9. Through-Drying of Tissue Paper - Experiments and Modelling
Sammanfattning : In through-drying of paper, the energy required for drying is supplied by hot air, which is forced through the paper structure. The area for heat and mass transfer is the internal surface area of the paper, which is often many times larger than the external web surface area (xy-plane). LÄS MER
10. Surface Characterization using Radiometric and Fourier Optical Methods
Sammanfattning : This thesis treats static and dynamic surface characterization using radiometric and Fourier optical methods. A Fourier optical method has been developed for real time image processing in paper production and printing applications. LÄS MER
