11. Ion beam etching of InP based materials
Sammanfattning : Dry etching is an important technique for pattern transferin fabrication of most opto-electronic devices, since it canprovide good control of both structure size and shape even on asub-micron scale. Unfortunately, this process step may causedamage to the material which is detrimental to deviceperformance. LÄS MER
12. Method Development in Quantitative and Structural Proteomics using Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
Sammanfattning : In this thesis, methods for studying different aspects of proteomics were developed with Fourier Transform Ion Cyclotron Resonance, (FTICR), mass spectrometry. The FTICR technique provides ultra-high mass resolving power, mass accuracy at sub ppm level and sensitivity in the attomole region. LÄS MER
13. Ion-Crosslinked Nanocellulose Hydrogels for Advanced Wound Care Applications
Sammanfattning : A current trend in the field of wound care is the development of wound healing materials that are designed to address specific types of wounds or underlying pathologies to achieve improved healing. At the same time, there is a societal drive to replace synthetic materials with renewable alternatives. LÄS MER
14. TCF Bleaching of Softwood Kraft Pulp. Metal Management Procedures
Sammanfattning : The aim of this work has been to increase knowledge of the influence of the metal ion content in softwood kraft pulp on peroxide bleaching and to investigate the effects of different metal management procedures at various stages in the production of TCF pulps (i.e. LÄS MER
15. Anammox-based systems for nitrogen removal from mainstream municipal wastewater
Sammanfattning : Nitrogen removal from municipal wastewater with the application of deammonification process offers an operational cost reduction, especially if it is combined with a maximal use of organic content of wastewater for biogas production. In this thesis, two approaches for integration of the deammonification process into the municipal wastewater treatment scheme were studied. LÄS MER
