11. Design of new materials with crystal structure-related properties : The role of lone pair cations
Sammanfattning : Non-centrosymmetry and low-dimensional arrangements, e.g. chains or layers, are very attractive structural characteristics of crystalline compounds since they are linked to some physical properties including nonlinear optical activity, ferroelectricity and magnetic frustration.

12. Order and interfaces in epitaxial heterostructures : Structure and magnetism
Sammanfattning : The work in this dissertation is devoted to investigating order and interfaces in epitaxial heterostructures. To achieve that the software tool box GenL was developed for simulating and fitting x-ray diffraction patterns from epitaxial thin films, which is used to access structural information on the length scales of interfaces and atomic bonds.

13. Interfacial colloidal particle films and their structure formation
Sammanfattning : Abstract toInterfacial colloidal particle films andtheir structure formation; a licentiate thesis, whichwill be presented by Sandra Rödner in Q2, 29 November 2002at 13.00.Colloidal particles can be made to organise themselves intoordered arrays. LÄS MER
14. Structures and Properties of Ferroelectric Liquid Crystal Displays
Sammanfattning : Liquid crystals have unique physical properties as they combine the features of solids and liquids. In thermotropic liquid crystals the degree of order varies with temperature resulting in an appearance of intermediate phases. LÄS MER
15. Controlling function by structure-intermolecular interactions and crystal engineering with N-donor ligands
Sammanfattning : In the solid state regime, crystal engineering based on non-covalent synthesis requires an intuition about the intermolecular forces that can dictate the molecular architecture. Hydrogen bonds have become an instrumental tool in the self assembly and supramolecular chemistry. LÄS MER
