1. Ionic Conduction and Bond Valence in Glasses
Sammanfattning : Ion conducting glasses are highly interesting for several different applications, among them, chemical sensors, smart windows with variable optical properties and as electrolytes in batteries. The last example can take full advantage of the ease with which a thin film (... LÄS MER
2. Laser processing of Silica based glass
Sammanfattning : The main topic of this thesis work is photosensitivity and photo-structuring of optical fibers and bulk glass. Although research in the field of photosensitivity in glass and optical fibers has been ongoing for more than three decades, the underlying mechanisms are still not well understood. LÄS MER
3. Local structure and composition : in additively manufactured bulk metallic glasses and composites
Sammanfattning : Additive manufacturing enables the production of complex multi-material geometries and bulk metallic glass parts beyond their critical casting thickness. The local modification of structure, composition, and properties is explored in this thesis with the aim to design novel composite materials and functional gradients. LÄS MER
4. Structural Investigations of Complex Glasses by Solid-state NMR
Sammanfattning : This PhD thesis presents structural investigations of amorphous inorganic materials: oxide and oxynitride glasses and mesoporous bioactive glasses (MBGs), by solid-state Nuclear Magnetic Resonance (NMR). Lanthanum oxide and oxynitride [La-Si-(Al)-O-(N)] glasses have a large number of potential applications due to their physical properties. LÄS MER
5. Organisering för individualitet : transparenta och opaka aspekter i utvecklingsprocesser
Sammanfattning : The doctoral dissertation 'Organising for individuality - transparent and opaque aspects of development processes' deals with the relationship between a company's ability to develop new products and its ability to change the way it organises its product development activities. The dissertation is based on a real time study of two product development and two organizational change processes at Orrefors Kosta Boda AB. LÄS MER
