  2. 1. Structural, Kinetic and Thermodynamic Aspects of the Crystal Polymorphism of Substituted Monocyclic Aromatic Compounds

    Author : Michael Svärd; Åke Rasmuson; Hugo Meekes; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymorphism; crystallization; thermodynamics; kinetics; nucleation; crystallography; solubility; phase equilibria; polymorphic transformation; solution history; metastable zone; classical theory of nucleation; two-step theory of nucleation; cluster; crystal structure prediction; lattice energy; molecular mechanics; force field; electrostatic potential; potential energy hypersurface; m-aminobenzoic acid; m-hydroxybenzoic acid; Chemical engineering; Kemiteknik;

    Abstract : This work concerns the interrelationship between thermodynamic, kinetic and structural aspects of crystal polymorphism. It is both experimental and theoretical, and limited with respect to compounds to substituted monocyclic aromatics. READ MORE

  4. 2. There Is an Alloy at the End of the Rainbow: Structure and Optical Properties From Bulk to Nano

    Author : Magnus Rahm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thermodynamics; optical properties; dielectric functions; hydrides; alloy cluster expansions; alloys; nanoalloys;

    Abstract : Mixing different chemical species and decreasing dimensions to the nanoscale are two powerful approaches for improving materials. In both cases new properties emerge, and structure, composition, and chemical ordering can be tuned to tailor materials for specific purposes. READ MORE

  5. 3. Physical characterization of exosomes and other extracellular vesicles using surface-based sensing

    Author : Deborah Rupert; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoparticle tracking analysis; exosomes; scattering; surface-based biosensing; optical density; cluster of differentiation 63 CD63 ; liposomes; label-free; fluorescence; surface plasmon resonance; Extracellular vesicles; specificity; antibody; lipid content; single particle; quantification; size distribution; optical waveguide microscopy;

    Abstract : Extracellular vesicles (EVs) are hundred of nanometer sized particles secreted by almost all cell types. Exosomes are one type of EVs today intensively investigated due to the increased evidence suggesting that they play important roles as communicating vehicles in a broad range of physiological processes, pathological conditions and disease diagnostics.

  6. 4. Doping effects on the structural and optical properties of GaN

    Author : Sergey Khromov; Galia Pozina; Lars Hultman; Thierry Bretagnon; Linköpings universitet; []
    Keywords : ;

    Abstract : Today there is a strong drive towards higher efficiency light emitters and devices for power electronics based on GaN and its ternary compounds. Device performance can be improved in several ways on the material level. READ MORE

  7. 5. Numerical studies of spin chains and cold atoms in optical lattices

    Author : Sara Bergkvist Sylvan; Anders Rosengren; Richard Scalettar; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teoretisk Fysik; Kondenserade materiens teori; Condensed matter physics; Kondenserade materiens fysik;

    Abstract : An important, but also difficult, research field in condensed matter physics is that of strongly correlated systems. This thesis considers two topics in this field. The first topic is disorder and frustration in spin models. The introduction of disorder into quantum spin chains creates a complex problem. READ MORE
