16. High resolution microstructural characterization of oxide thin films and interfaces
Sammanfattning : Oxide interfaces can introduce properties that are different compared to thecorresponding crystal bulk properties. The properties can be tuned by changing thestructure. It has become clear that these oxide interface systems are potentiallysuitable for future electronic devices with unique and tailored properties. LÄS MER
17. Temperature dependent atomic-scale modeling of interfaces in cemented carbides
Sammanfattning : Material properties can now be calculated directly from first principles using density functional theory (DFT) which has a great predictive power and can, in cases that are difficult to approach experimentally, provide crucial insights on the atomic and electronic level. Such cases include the thermodynamics of interfaces and surfaces which are crucial factors for the structure and macroscopic properties of many materials, where cemented carbides are one example.

19. Influence of Ageing on Material Properties at Interfaces in Composite Insulators
Sammanfattning : High quality of internal interfaces in composite insulators for high voltage applications is necessary for securing durability of their functionality. Weak macroscopic interfaces between the glass fibre reinforced (FRP) epoxy core and the silicone rubber (SIR) housing, such as spots with reduced bonding or a loss of the adhesion as well as presence of foreign contaminants, can appear to have an accelerating effect on the evolution of ageing processes, though it may take years before the first signs of processes endangering the insulator function appear.

20. Atomic-scale modelling of interfaces in cemented carbides: wetting and strength
Sammanfattning : Cemented carbides are composite materials of great technological and industrial importance. They have a unique combination of hardness and toughness and are therefore used widely as tool materials in applications where both high hardness and toughness are demanded. These applications include among others: mining, turning, cutting and milling. LÄS MER
