6. Modelling of a single layer graphene membrane
Sammanfattning : The present contribution deals with the modeling of thin graphene membranes. Such membranes have a significant electrical and physical properties used for nano or microdevices like resonators and Atomic Force/mass Measurements (AFM) [1]. The membrane is considered as a homogenized graphene monolayer on the macroscopic structural scale. LÄS MER
7. Concepts for improving ethanol productivity from lignocellulosic materials : encapsulated yeast and membrane bioreactors
Sammanfattning : Lignocellulosic biomass is a potential feedstock for production of sugars, which can be fermented into ethanol. The work presented in this thesis proposes some solutions to overcome problems with suboptimal process performance due to elevated cultivation temperatures and inhibitors present during ethanol production from lignocellulosic materials.

8. Desalination using Membrane Distillation : Experimental and Numerical Study
Sammanfattning : Desalination has been increasingly adopted over the last decades as an option, and sometimes as a necessity to overcome water shortages in many areas around the world. Today, several thermal and physical separation technologies are well established in large scale production for domestic and industrial purposes. LÄS MER
9. Cellular Dyes and Bioactive Peptides - Cell Membrane Interactions and Cellular Uptake
Sammanfattning : Knowledge about mechanisms behind interactions of molecules with biomembranes and cellular uptake is very important for understanding biological processes and for drug design. The work described in this thesis has focused on interactions of cellular dyes and bioactive peptides with cells and the cell membrane. LÄS MER
10. Membrane mediated aggregation of amyloid-β protein : a potential key event in Alzheimer's disease
Sammanfattning : The pathogenesis of Alzheimer’s disease (AD), the most common senile dementia, is a complex process. A crucial event in AD is the aggregation of amyloid-β protein (Aβ), a cleavage product from the Amyloid Precursor Protein (APP). LÄS MER
