1. 1. Formation stability and electronic structure of surfaces and interfaces from first principles

   Författare :Jochen Rohrer; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; band structure; van der Waals interaction; electronic structure; graphane; graphene; atomic structure; growth; thin film; interface; density functional theory; CVD; Alumina; nucleation;

   Sammanfattning : This thesis deals with two closely interwoven aspects of first-principle(density functional theory) materials modeling:(1)~prediction of atomic structure & chemical composition,and (2)~prediction of electronic properties.In the first part, we focus on atomic structure (AS) and chemical composition (CC) of surface and interface systems.

3. 2. A Dynamic View of Melodic Organization and Performance : Perception of Structure and Emotional Expression in Music

   Författare :Erik Lindström; Alf Gabrielsson; Andreas C. Lehmann; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; accents; emotion; expression; musical structure; tonal structure; Psykologi; Psychology; Psykologi;

   Sammanfattning : Psychology of music has shown renewed interest in how music expresses emotion to listeners. However, there is an obvious lack of research on how interactions between musical factors such as harmony, rhythm, melodic contour, loudness, and articulation may affect perceived emotion. LÄS MER

4. 3. Nanoscale structure forming processes : Metal thin films grown far-from-equilibrium

   Författare :Viktor Elofsson; Kostas Sarakinos; Robert D. Boyd; Diederik Depla; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Thin film growth from the vapor phase has for a long time intrigued researchers endeavouring to unravel and understand atomistic surface processes that govern film formation. Their motivation has not been purely scientific, but also driven by numerous applications where this understanding is paramount to knowledge-based design of novel film materials with tailored properties.

5. 4. Control of Structure of Filled Polymer Blends

   Författare :Claes Hammer; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; interactions; modelling; polypropylene; structure control; dynamic mechanical properties; filled polymer blends;

   Sammanfattning : This thesis deals with the control and analysis of the structure of filled immiscible polypropylene (PP) blends. The intention has also been to implement the knowledge gained in respect of commercially interesting systems as filled PP/(ethylene propylene copolymer (EP)) blends. LÄS MER

7. 5. Vanadate and Peroxovanadate Complexes of Biomedical Relevance : A speciation approach with focus on diabetes

   Författare :András Gorzsás; Lage Pettersson; Carlos F. G. C. Geraldes; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; vanadium; hydrogen peroxide; lactate; citrate; phosphate; alanyl serine; picolinic acid; speciation; formation constants; equilibrium; solution structure; potentiometry; NMR 51V; 31P; 13C; 1H ; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

   Sammanfattning : Diabetes mellitus is one of the most threatening epidemics of modern times with rapidly increasing incidence. Vanadium and peroxovanadium compounds have been shown to exert insulin–like actions and, in contrast to insulin, are orally applicable. However, problems with side–effects and toxicity remain. LÄS MER
