1. Betulin-modified cellulosic textile fibers with improved water repellency, hydrophobicity and antibacterial properties
Sammanfattning : Textiles made from natural sources, such as cotton and flax, have advantages over those made of synthetic fibers in terms of sustainability. Unlike major synthetic fibers that have a negative impact on the environment due to poor biodegradability, cotton cellulose is a renewable material. LÄS MER
2. Toward Anti-icing and De-icing Surfaces : Effects of Surface Topography and Temperature
Sammanfattning : Icing severely affects society, especially in the Nordic countries. Iceaccumulation can result in critical performance problems and safetyconcerns for instance in road, air and sea transportation, transmissionlines, marine and offshore structures, wind turbines and heat exchangers.

3. Development of Protein Microarray Chip Technology: An Outlook towards Proteomics and Diagnostics
Sammanfattning : One attractive method for monitoring biomolecular interactions in a highly parallel fashion is the use of microarrays. Microarrays can be applied for screening proteins which makes it an attractive tool in clinical diagnostics, drug discovery studies and basic protein research; even though many methodological challenges and ones relating to the quality control of microarrays still need to be solved.

4. Adsorption behaviour of bottle-brush and block copolymers at solid-liquid interfaces
Sammanfattning : This thesis was spurred on by needs of current scientific and technological developments in the area of surface modification by use of adsorbed polymer layers. The importance of surface properties of polymer layers can be imparted in a broad spectrum of interfacial-related applications like lubrication, colloidal stability, detergency, and protein resistant surfaces, to just mention a few.

5. The missing links : Towards an Informed Substitution of Durable Water Repellent Chemicals for Textiles
Sammanfattning : Durable water repellents (DWRs) that provide liquid repellency to functional textiles are part of an ongoing global substitution process. The process of substitution was initiated after DWRs based on side-chain fluorinated polymers (long-chain SFPs) were identified to contribute to the diffuse release of long-chain perfluoroalkyl acids (PFAAs) to the environment.
