  2. 1. Insights into Materials Properties from Ab Initio Theory : Diffusion, Adsorption, Catalysis & Structure

    Author : Andreas Blomqvist; Rajeev Ahuja; Christopher Wolverton; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Molecular dynamics; Diffusion; Catalysis; Adsorption; Random structure search; Hydrogen-storage materials; Phase-change materials; Defects and diffusion; Defekter och diffusion; Surfaces and interfaces; Ytor och mellanytor; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : In this thesis, density functional theory (DFT) calculations and DFT based ab initio molecular dynamics simulations have been employed in order to gain insights into materials properties like diffusion, adsorption, catalysis, and structure. In transition metals, absorbed hydrogen atoms self-trap due to localization of metal d-electrons. READ MORE

  4. 2. Health among people with psychotic disorders and effects of an individualized lifestyle intervention to promote health

    Author : Marjut Blomqvist; Henrika Jormfeldt; Anna Sandgren; Ing-Marie Carlsson; Andreas Ivarsson; Sally Hultsjö; Högskolan i Halmstad; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Complex intervention; health promotion; lifestyle intervention; mental health nursing; psychiatric out-patient services; psychotic disorders; qualitative content analysis; quasi-experimental study; statistical analysis;

    Abstract : The overall aim of the thesis was to increase knowledge of health among people with psychotic disorders such as schizophrenia and other long-term psychotic conditions. The aim was also to investigate health effects, in terms of clinical health outcomes and self-reported questionnaires, of atwo-year individualized lifestyle intervention implemented in psychiatric outpatient services involving cooperation with the municipal social psychiatry services.

  5. 3. Computational Insights into Atomic Scale Wear Processes in Cemented Carbides

    Author : Emil Edin; Rajeev Ahuja; Andreas Blomqvist; Jonas Östby; Wei Luo; Hannes Jónsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; WC; Cemented Carbides; Diffusion; Wear; Interfaces; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : As Ti-alloys become more and more utilized the need for efficient and robust manufacturing of Ti-alloy components increase in importance. Ti-alloys are more difficult to machine than e.g. steel, mainly due to their poor thermal conductivity leading to rapid tool wear. READ MORE

  6. 4. Transition Metals and their Carbides, Nitrides and Carbonitrides : from a CALPHAD Perspective

    Author : Fredrik Haglöf; Malin Selleby; Andreas Blomqvist; Susanne Norgren; Mauro Palumbo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The CALPHAD (CALculation of PHAse Diagrams) method consists of three cornerstones, i.e. experiments, computational methods (e.g. READ MORE

  7. 5. Developing the third generation Calphad models and descriptions: a journey from unary to higher-order systems

    Author : Zhangting He; Malin Selleby; Huahai Mao; Andreas Blomqvist; Gabriele Cacciamani; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The third generation Calphad descriptions aim to provide more accurate computational thermodynamics for an extended temperature range, i.e. from 0 K to high temperatures. In order to achieve such a goal, new Calphad models are needed. READ MORE
