1. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces
Sammanfattning : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.

2. Tailoring Surface Properties of Bio-Fibers via Atom Transfer Radical Polymerization
Sammanfattning : The potential use of renewable, bio-based polymers in high-technological applications has attracted great interest due to increased environmental concern. Cellulose is the most abundant biopolymer resource in the world, and it has great potential to be modified to suit new application areas. LÄS MER
3. 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.

4. Diamond Microfabrication for Applications in Optics and Chemical Sensing
Sammanfattning : Diamond is a material with many exceptional properties. In this thesis methods for fabrication of microstructures as well as several applications of such structures in optics, microfluidics and electrochemistry are presented.A method for etching deep and highly precise gratings is described.

5. Hydrophobic and superhydrophobic coatings for corrosion protection of steel
Sammanfattning : Since metals in general, and steels in particular, are vital construction materials in our modern society, the corrosion protection of said materials is of great importance, both to ensure safety and to reduce costs associated to corrosion. Previously, chromium (VI) and other harmful substances were effectively used to provide corrosion protection to steel, but since their use was heavily regulated around year 2000, no coating has yet been developed that, in a fully satisfactory manner, replaces their corrosion protective properties.
