1. 41. Characterizing Chromatography Media : NMR-based Approaches

   Författare :Fredrik Elwinger; István Furó; Stéphane Viel; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chromatography; nuclear magnetic resonance; NMR; self-diffusion; magic-angle spinning; quantitative; distribution coefficient; pore size; Kemi; Chemistry;

   Sammanfattning : Liquid chromatography is an essential technique in manufacturing biopharmaceuticals where it is used on all scales from analytical applications in R&D to full-scale production. In chromatography the target molecule, typically a protein, is separated and purified from other components and contaminants. LÄS MER

3. 42. Structural Investigations of Complex Glasses by Solid-state NMR

   Författare :Ekaterina Leonova; Mattias Edén; Robin Harris; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glass; glass structure and properties; NMR; magic angle spinning; chemical shift; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

   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

4. 43. Rotational Resonance in the Nuclear Magnetic Resonance of solids

   Författare :Torgny Karlsson; S Vega; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical Chemistry; fysikalisk kemi;

   Sammanfattning : This thesis presents new physical phenomena in the rotational resonance NMR of magic-angle spinning solids. The theory of a new class of nuclear spin echoes is developed. LÄS MER

5. 44. Structure and chemical ordering in metallic nanoparticles from atomic scale modeling

   Författare :Magnus Rahm; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; regular truncated octahedron; chemical ordering; nanoparticle shapes; molecular dynamics; icosahedron; Monte Carlo; modeling; Marks decahedron; nanoparticle structures;

   Sammanfattning : In the last decades, a wide range of attractive properties have put metallic nanoparticles in the spotlight. These properties, often related to optical response and catalytic performance, are to a large extent dependent on structure and chemical ordering, that is, the distribution of elements in the nanoparticle.

7. 45. The Viking Way : Religion and War in Late Iron Age Scandinavia

   Författare :Neil Price; Martin Carver; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Viking Age; Vikings; Óðinn; seiðr; sorcery; shamanism; warfare; Norse religion; Norse mythology; Sámi; Arkeologi; Archaeology subjects; Arkeologiämnen; arkeologi; Archaeology;

   Sammanfattning : The social role of magic is a prevalent theme of the medieval Icelandic sagas that claim to describe life several centuries earlier in the Viking Age, and indeed also saturates the Eddic poetry that is our primary source for the mythology and cosmology of the time. However, little archaeological or historical research has been done to explore what this aspect of ritual may really have meant to the men and women of late Iron Age Scandinavia. LÄS MER
