  2. 1. Atomistic modelling of functional solid oxides for industrial applications : Density Functional Theory, hybrid functional and GW-based studies

    Author : Cecilia Århammar; Rajeev Ahuja; Steven Louie; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; density functional theory; oxides; GW; Condensed matter physics; Kondenserade materiens fysik; Magnetism; Magnetism; Defects and diffusion; Defekter och diffusion;

    Abstract : In this Thesis a set of functional solid oxides for industrial applications have been addressed by first principles and thermodynamical modelling. More specificially, measurable quantities such as Gibbs free energy, geometry and electronic structure have been calculated and compared when possible with experimental data. READ MORE

  4. 2. Population Genetics of Human Genomic Elements

    Author : Thijessen Naidoo; Mattias Jakobsson; Guillaume Achaz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population genetics; human genome; functional elements; natural selection; pseudogenes; loss-of-function; gene regulation; Y chromosome; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Abstract : The genomes of living organisms are composed of a multitude of functional units, which interact with each other and their environment in a highly regulated fashion, to facilitate the expression of an enduring (and evolving) phenotype. Several approaches have emerged in the effort to identify these functional units and explore their activities. READ MORE

  5. 3. Functional Metallic Glasses

    Author : Ansar Masood; Lyubov Belova; K. Venkat Rao; Lars Arnberg; KTH; []
    Keywords : Bulk Metallic glasses; glass forming ability; soft magnetism; thin films; magnetic properties; magnetic hardening; plasticity; biocompatibility;

    Abstract : For decades, Metallic Glass, with its isotropic featureless structure while exhibiting outstanding mechanical properties was possible only at a high rate of quenching and with at least one dimension in the submicron regime.  This limitation was overcome with the discovery of Bulk Metallic glasses, BMGs, containing three or more elements following the additional two empirical rules of optimum geometric size differences and negative energy of mixing among the constituent elements.

  6. 4. Epidermal keratinocytes studied by X-ray microanalysis, with special reference to contact dermatitis : In vivo and in vitro studies of functional changes in human cells

    Author : Anders Grängsjö; Uppsala universitet; []
    Keywords : Medical sciences; X-ray microanalysis; elements; epidermis; keratinocytes; proliferation; cell membrane damage; Ki67; irritants; intracellular elemental content; keratinocyte culture; HaCaT; NHEK; RT-PCR; immunohistochemistry; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; anatomi; Human Anatomy;

    Abstract : By determining the intracellular elemental content, information can be obtained on the physiological status of cells. The cellular content of sodium, magnesium, phosphorus, sulfur, chloride, potassium and calcium can be indicative for proliferation, cell membrane damage or cell death. READ MORE

    Abstract : This work focuses on the design, synthesis, characterization, and application projections of low-coordinated heavy pnictogen-containing (described by the generic letter E, hence E=C) phosphaalkenes (P=C) and arsaalkenes (As=C), with emphasis on the E=C group motifs. The work aims to understand their functional and modular character, reactivity, and potential applications by stabilizing, isolating, and characterizing these species in low-coordination environments.
