1. 16. Electrochromism in Metal Oxide Thin Films : Towards long-term durability and materials rejuvenation

   Författare :Rui-Tao Wen; Claes-Göran Granqvist; Agustín R. González-Elipe; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochromic; smart windows; long-term durability; degradation kinetics; ion trapping; de-trapping; materials rejuvenation; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

   Sammanfattning : Electrochromic thin films can effectively regulate the visible and infrared light passing through a window, demonstrating great potential to save energy and offer a comfortable indoor environment in buildings. However, long-term durability is a big issue and the physics behind this is far from clear. LÄS MER

3. 17. First-principles investigations of planar defects

   Författare :Lu Song; Levente Vitos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Two types of planar defects, phase interface and stacking fault, are addressed in this thesis. The investigation is mainly carried out for stainless steels which are fundamental materials in modern society. For the phase interface, we investigate the metallic bcc/bcc and fcc/bcc phase interfaces. LÄS MER

4. 18. Sharers in Divine Nature : 2 Peter 1:4 in Its Hellenistic Context

   Författare :James M Starr; Centrum för teologi och religionsvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Hellenistic philosophy; incorruption; virtue; ethics; participation; knowledge; koinônos; divine nature; Epictetus; Seneca; Stoicism; Plutarch; Philo; Josephus; Old Testament; Paul; 2 Peter; General Epistles; Bible; New Testament; Corpus Hellenisticum; Bibelvetenskap;

   Sammanfattning : This book offers a theological study of an expression unique in biblical literature concerning the purpose of life: “that you might become sharers in divine nature” (2 Peter 1:4). Following an analysis of the text-immanent features in 2 Peter 1:1—11, the study delineates comparable notions of “sharers in divine nature” in selected writings that were current in the first century and contrasts these with 2 Peter.

5. 19. Experimental investigations of model catalytic surface reactions on metal and metal oxide surfaces

   Författare :Kess Marks; Henrik Öström; Ellen Backus; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kemisk fysik; Chemical Physics;

   Sammanfattning : In the development of renewable energies catalysis plays an important role, for example in the production of H2 gas that drives fuel cells, or in the decomposition of annoying by-products of renewable energy production. Most catalysts and catalytic processes currently used in the industry have their roots in macroscopic empirical investigations and trial and error-based optimization. LÄS MER

7. 20. Electronic structure and exchange interactions from ab initio theory : New perspectives and implementations

   Författare :Ramon Cardias Alves de Almeida; Olle Eriksson; Anders Bergman; Attila Szilva; R. B. Muniz; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ab initio; exchange interactions; non-collinear magnetism; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : In this thesis, the magnetic properties of several materials were investigated using first principle calculations. The ab initio method named real space linear muffin-tin orbitals atomic sphere approximation (RS-LMTO-ASA) was used to calculate the electronic structure and magnetic properties of bulk systems, surface and nanostructures adsorbed on surfaces.
