  2. 11. Choice deferral, status quo bias, and matching

    Author : Gökhan Buturak; Handelshögskolan i Stockholm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : his thesis consists of three independent papers. They are put in reverse chronological order according to when they were initiated. The first paper, which is a joint work with özgür Evren, extends the standard rational choice framework with the option to postpone the act of selecting an alternative. READ MORE

  4. 12. Atomistic simulation and experimental studies of transition metal systems involving carbon and nitrogen

    Author : Jiaying Xie; Seshadri Seetharaman; Oleg Ostrovski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition metal carbides; Transition metal nitrides; Transition metal carbo-nitrides; Lattice inversion method; Interatomic potential; Atomistic simulation; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The present work was initiated to investigate the stability, structural and thermodynamic properties of transition metal carbides, nitrides and carbo-nitrides by atomistic simulations and experimentations. The interatomic pair potentials of Cr-Cr, Mn-Mn, Fe-Fe, C-C, Cr-C, Mn-C, Fe-C, Cr-Fe, Cr-N and Mn-N were inverted by the lattice inversion method and ab initio cohesive energies, and then employed to investigate the properties of Cr-, Mn- and Fe-carbides by atomistic simulations in this work.

  5. 13. In pursuit of next generation photovoltaics : An electronic structure study of lead-free perovskite solar cells

    Author : Axel Erbing; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : The recent development of perovskite-based solar cells have shown a remarkably fast increase in power conversion efficiency making them a promising low-cost alternative to conventional cells. The most successful class of materials however, the lead-halide perovskites, are held back due to toxicity and stability issues significantly limiting their use. READ MORE

  6. 14. Structural and Functional Studies of Membrane Proteins : From Characterisation of a Fatty Acyl-CoA Synthetase to the Discovery of Superoxide Oxidase

    Author : Camilla A. K. Lundgren; Martin Högbom; James Imlay; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

    Abstract : This thesis is divided into three parts; the first part describes a method for efficient screening of membrane proteins for crystallography. By utilising the properties of a folding reporter GFP it is possible to quickly and accurately screen the stability of a protein in a range of conditions without full purification. READ MORE

  7. 15. Novel Methods for Synthesis of High Quality Oligonucleotides

    Author : Andrey Semenyuk; Marek Kwiatkowski; Ulf Landegren; Joachim W. Engels; Uppsala universitet; []
    Keywords : Organic chemistry; oligonucleotide; solid-phase synthesis; RNA synthesis; phosphoramidite; abasic sites; depurination; 2 -O-DTM; protecting group; cartridge; conjugate; dithiomethyl linker; base-stable linker; oligonucleotide purification; nucleoside; Organisk kemi;

    Abstract : The first part of the work describes a procedure of oligonucleotide purification using a reversed-phase cartridge. The developed method employs a very efficient yet mild oligonucleotide detritylation on the cartridge support allowing fast purification of oligonucleotides regardless of their 5´-modification.
