11. Anomalous Spectral Lines in Space and Laboratory Plasmas - Studies with HST and CRYRING
Sammanfattning : Eta Carinae is one of the most massive and luminous stars in the Galaxy. A huge bipolar nebula and an equatorial disk give the object a characteristic shape. Close to the star there are gas clouds, which emit intriguing emission line spectra. LÄS MER
12. Hubble Space Telescope Spectroscopy of Eta Carinae and Chi Lupi
Sammanfattning : Eta Carinae is a super-massive, super-luminous star. It is surrounded by a bipolar nebula, the "Homunculus", and several blobs of ejected gas which are the source of a complex emission-line spectrum. LÄS MER
13. Additively Manufactured Inconel 718 : Microstructures and Mechanical Properties
Sammanfattning : Additive manufacturing (AM), also known as 3D printing, has gained significant interest in aerospace, energy, automotive and medical industries due to its capabilities of manufacturing components that are either prohibitively costly or impossible to manufacture by conventional processes. Among the various additive manufacturing processes for metallic components, electron beam melting (EBM) and selective laser melting (SLM) are two of the most widely used powder bed based processes, and have shown great potential for manufacturing high-end critical components, such as turbine blades and customized medical implants.

14. Foam Formation and Starch Gelatinization with Alpha-Crystalline Emulsifiers
Sammanfattning : In the baking industry, emulsifiers in the alpha-gel state are used for foam formation. This thesis focuses on some parts of the effects of the emulsifier: how the foam formation and foam stability are influenced by the physical state of the emulsifier, how emulsifiers change the gelatinization and gel formation of starch, and the impact that these factors may have in a true product such as a sponge cake.

15. Novel room temperature ferromagnetic semiconductors
Sammanfattning : In today's information world, bits of data are processed bysemiconductor chips, and stored in the magnetic disk drives.But tomorrow's information technology may see magnetism (spin)and semiconductivity (charge) combined in one 'spintronic'device that exploits both charge and 'spin' to carry data (thebest of two worlds).
