1. Machinability variations in Alloy 718 —With focus on machining of turbine components
Sammanfattning : In gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). LÄS MER
2. On the Machinability of Ductile and Strain Hardening Materials - Models and Methods for Analyzing Machinability
Sammanfattning : As quality and performance demands on today’s products increases, more and more advanced materials are being used during modern production. The problem is however that this in turn place new demands on the machining processes utilized. LÄS MER
3. Characterisation of Aqueous Solutions, Liquid Crystals and Solid State of Non-ionic Polymers in Association with Amphiphiles and Drugs
Sammanfattning : Cellulose ethers and polyethylene glycols are used in drug formulations as water swelling or water soluble matrices. Polar lipids, for example monoglycerides, and surfactants can be used to solubilise hydrophobic or amphiphilic drugs and to formulate potential drug delivery vehicles such as emulsions, liposomes and cubic phases.

4. Twist-Symmetric Periodic Structures : Properties and Applications
Sammanfattning : In this thesis, periodic structures with higher symmetries symmetries are discussed. The main focus of the thesis is on twist symmetries. Importantly, the attractive properties of twist symmetries for the control of electromagnetic wave propagation are demonstrated. LÄS MER
5. Lipid based formulations for topical application: characterization and delivery of active substances
Sammanfattning : In this thesis, the interaction between lipids, solvents and active substances in lipid based formulations have been studied and related to formulation structure or release behavior on human skin or a model thereof. For the different investigations, isotropic equilibrium lipid phases, i.e. LÄS MER
