11. Quantitative 3D reconstruction of porous polymers using FIB-SEM tomography -correlating materials structures to properties of coatings for controlled drug release
Sammanfattning : Porous networks are found in a wide range of different advanced and technologically important materials and influence the materials properties. The networks are active components in for example batteries, food and pharmaceuticals. The interconnectivity of a network strongly influences the transport properties. LÄS MER
12. Computational model of abdominal aortic aneurysm inception and evolution
Sammanfattning : Incidence of abdominal aortic aneurysm (AAA) is increasing in the aging society of the western world. Development of AAA is mostly asymptomatic and is characterized by a bulge in the abdominal aorta. However, AAA may suddenly rupture, which results in an internal bleeding associated with a high mortality rate. LÄS MER
13. Polymer-coated paper and board - Role of substrate, polymer characteristics and additives
Sammanfattning : The surface roughness of paper or board has a significant influence on the homogeneity of an applied polymer film, and this thesis discusses how it may be improved by a surface treatment, e.g. high-temperature calendering or precoating. LÄS MER
14. The influence of microstructure on the crack initiation and propagation in Al-Si casting alloys
Sammanfattning : For reducing the CO2 footprint in many industrial fields, the goal is to produce lighter components. The aluminium-silicon (Al-Si) cast alloys are promising candidates to fulfill these goals with a high weight-to-strength ratio, good corrosion properties, excellent castability, and recyclable material.

15. Modeling and Simulation of Microdialysis in the Deep Brain Structures
Sammanfattning : Microdialysis is a method for monitoring of the local biochemical environment in a region of interest. The method uses a catheter, mimicking the function of a blood capillary, to sample substances from the surrounding medium through diffusion. LÄS MER
