6. Novel Layered and 2D Materials for Functionality Enhancement of Contacts and Gas Sensors
Sammanfattning : Chemical gas sensors are widely-used electronic devices for detecting or measuring the density levels of desired gas species. In this study, materials with established or potential applications for gas sensors are treated. LÄS MER
7. Upgrading Cellulose Networks: Conquering Limitations in Fiber Foams
Sammanfattning : The battle to create structural materials with low environmental impact demands the investiture of two champions: porous structures and cellulose substrates. The dominant solutions when constructing strong lightweight materials are plastic and metallic foams, while currently, cellulose fiber foams suffer from challenges which hamper their development.

8. Nanoparticle assisted tribofilm formation and material transfer studied with SEM and TEM
Sammanfattning : The discovery and subsequent synthesis of metal containing fullerenes- IFS (Inorganic Fullerene-like Structures) by R. Tenne et al. has generated considerable scientific interest with great potential impact in many industrial application areas such as lubrication. LÄS MER
9. Design of carbide-based nanocomposite coatings
Sammanfattning : In this thesis research on synthesis, microstructure and properties of carbide-based coatings is reported. These coatings are electrically conducting, and can be tailored for high hardness, low friction and wear, along with load-adaptive behaviour. Tailoring these properties is achieved by controlling the relative phase content of the material. LÄS MER
10. Polymeric Materials for Bearing Applications : Tribological Studies in Lubricated Conditions
Sammanfattning : One of the most important demands in hydropower and other industries today stems from the emphasis on preserving the environment. Usage of mineral and synthetic oils in sliding bearings of hydropower plants raises concerns about the environmental impact of these lubricants in case of spillage into downstream water. LÄS MER
