1. Functionalization and characterization of surface supported lipid membranes and their application in cell culture
Sammanfattning : Phospholipid bilayers supported on a solid surface constitute a versatile, biomimetic platform for a variety of applications, such as biosensing, drug delivery research, cell engineering and as cell membrane mimics in fundamental cell research. Phosphocholine supported lipid bilayers are resistant to cell attachment in a wide range of conditions, and can be functionalized with bioactive signaling molecules to promote specific interactions with cells.

Sammanfattning : Two non-linear Rankine-source panel methods are developed and implemented in the same computer code. The first method uses a four-point upwind operator on the free-surface to compute the velocity derivatives and to enforce the radiation condition while the second method uses an analytical expression for the velocity derivatives and a collocation point shift one panel upstream to prevent upstream waves.

4. Adsorption of surface active elements on the iron (100) surface A study based on ab initio calculationsDetta är en avhandling från Stockholm : KTH
Sammanfattning : In the present work, the structural, electronic properties, thermodynamic stability and adatom surface movements of oxygen and sulfur adsorption on the Fe surface were studied based on the ab initio method.Firstly, the oxygen adsorbed on the iron (100) surface is investigated at the three adsorption sites top, bridge and hollow sites, respectively.
