  2. 16. First-Principles Studies of Materials Properties : Pressure-Induced Phase Transitions & Functional Materials

    Author : Thanayut Kaewmaraya; Rajeev Ahuja; Scheicher Ralph; Naurang Saini; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Pressure-induced phase transitions; Ab-initio molecular dynamic; hybrid functional; Ab-initio random structure searching; Phase change material; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : This thesis presents the first-principles studies of materials properties within the framework of the density functional theory (DFT). The thesis constitutes three main parts, i. e., pressure-induced phase transitions in solids, data-storage and clean-energy materials. READ MORE

  4. 17. Functional PVC Additives : Core-Shell Nanoparticle and Renewable Resource Plasticizers

    Author : Bo Yin; Minna Hakkarainen; Mikael Skrifvars; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVC; nanocomposite; nanoparticle; core-shell; plasticizer; renewable resources; isosorbide; glucose;

    Abstract : Several functional poly(vinyl chloride) (PVC) additives were designed: PVC plasticizers made from renewable resources as alternatives to traditional phthalate plasticizers and core-shell nanoparticle-plasticizers with the aim to design an additive that can improve several mechanical properties simultaneously. Monomeric and oligomeric PVC plasticizers based of isosorbide and glucose were synthesized. READ MORE

  5. 18. On functional amenorrhoea : aetiological and epidemiological aspects with special reference to oral contraceptive treatment and anorexia nervosa

    Author : Hans Fries; Uppsala universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : .... READ MORE

  6. 19. Multi-functional Chromophores

    Author : Fredrik Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : As the push towards green energy become stronger, more efficient systems needs to be developed to compete with fossil fuel based systems. In modern Grätzel solar cells, most of the energy losses are inherited from the choice of chromophore and metal oxide surface. READ MORE

  7. 20. 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.
