11. Inhibition of Aluminium Pigments for Waterborne Coatings
Sammanfattning : Micrometer-sized aluminium flakes for use as pigments in waterborne coatings need protection, since the reaction between aluminium and water causes formation of aluminium hydroxide and hydrogen gas. The aluminium hydroxide destroys the metallic appearance of the pigment flakes and the evolution of hydrogen gas leads to a dangerous pressure build-up in the paint containers. LÄS MER
12. Beyond average crystal structures: understanding extended and local environments in proton-conducting Sc-substituted BaTiO3 perovskites
Sammanfattning : Proton conducting ceramics are very promising for applications concerned with energy sourcing with cleaner, safer, more abundant and cheaper alternatives to fossil fuels. These materials are still in development and advances in the field depend on a better understanding of the role of defects, their identification and location in the host framework, and the assessment of their short- and long-range dynamics and kinetics.

13. Characterisation of thermally induced degradation of high-temperature polymers and composites
Sammanfattning : This project aimed to broaden the knowledge of high-temperature polymers and composites when exposed to elevated temperatures and an oxygen-containing atmosphere. The main accent has been on thermosetting polyimide resins reinforced with carbon fibers. LÄS MER
14. Fundamental Studies Related to Gaseous Reduction of Iron Oxide
Sammanfattning : The demands for increasing the efficiency and lowering the environmental effects in iron and steelmaking industries have given rise to interests in application of direct reduction (DR) processes for production of iron by different gases. These advancements require comprehensive models for better control of the process conditions and the product properties. LÄS MER
15. Plasticized PVC Nanocomposites - The Effect of Montmorillonite Treatment and Processing Conditions on Material Properties
Sammanfattning : ABSTRACTPolyvinyl chloride (PVC) is one of the world’s most widely produced polymers. Its products are used in a wide range of areas such as building and construction, packaging, automotive, electrical/electronic and healthcare. PVC can easily be tailored to adapt material properties to specific applications. LÄS MER
