  2. 11. Magnetoplasmonic nanostructures

    Author : Emil Melander; Vassilios Kapaklis; Björgvin Hjörvarsson; Evangelos Th. Papaioannou; Paolo Vavassori; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Magnetism; nanostructures; plasmons; magneto-optics; magnetoplasmonics; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Surfaces that are nanopatterned, metallic, and magnetic can support surface plasmon resonances, providing an alternative and effective way to reconfigure flat optical components. Utilising a range of near- and far-field characterisation techniques, the optical and magneto-optical properties of lithographically patterned thin magnetic films are investigated. READ MORE

  4. 12. Structural Elements in Native Celluloses

    Author : Kristina Wickholm; KTH; []
    Keywords : cellulose I; accessible fibril surfaces; inaccessible fibril surfaces; para-crystalline cellulose; fibril aggregates; CP MAS 13C-NMR spectroscopy; spectral fitting; PCA; PLS;

    Abstract : In this thesis, a schematic model for the structure ofaggregated cellulose I fibrils is proposed. The model consistsof a crystalline fibril core surrounded by less orderedcellulose forms. These cellulose forms are fibril surfacesaccessible to water, fibril surfaces inaccessible to water andpara-crystalline cellulose. READ MORE

  5. 13. Liquid Crystalline SIloxane Dimers - Advanced Materials with Enhanced Properties

    Author : Nils Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 45 degree tilt angle; dimer; antiferroelectric; fluorinated; siloxane; polymer; liquid crystal; macrocycle; ferroelectric;

    Abstract : The liquid crystal state is a complex state with many kinds of different molecular attractive and repulsive forces that results in various kinds of phases. Since the pioneering works by Vorländer in the early 20th century, liquid crystal research has to a great extent been depending on careful systematic studies of the structure/property relationships in series of similar liquid crystalline materials.

  6. 14. Multiscale Modelling of a Nanoelectromechanical Shuttle

    Author : Caroline Huldt; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DFT; Nanoelectromechanics; Mesoscopics; Shuttle; Multiscale;

    Abstract : Nanoelectromechanical systems couple mechanical and electronic degrees of freedom creating a new type of electrical components. The nanoelectromechanical shuttle consists of a double junction with a movable central island. READ MORE
