  1. 16. Methods for modelling lattice structures

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Mona Kouach; [2019]
    Keywords : Lattice structures; Finite element method; Homogenization; Representative volume element;

    Abstract : The application of lattice structures have become increasingly popular as additive manufacturing (AM) opens up the possibility to manufacture complex configurations. However, modelling such structures can be computationally expensive. READ MORE

  3. 17. Automated Orienting of Water Molecules in Neutron Crystal Structures

    University essay from Lunds universitet/Kemiska institutionen

    Author : Axl Eriksson; [2019]
    Keywords : Teoretisk kemi; Theoretical chemistry; Crystallography; Neutron crystallography; X-ray crystallography; Phenix.refine; Method development; Model improvement; Chemistry;

    Abstract : A protein’s function is directly related to its structure, which is in a water medium where it is affected by hydrogen bonds and the hydrophobic effect. These interactions are in turn dependent on the water molecules’ orientations around the protein. Therefore, it is vital to have correct orientations for the water molecules. READ MORE

  4. 18. Investigation of magnetic order in nickel-5d transition metal systems

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Konstantinos Papadopoulos; [2019]
    Keywords : muSR; muons; skyrmions; magnetism; transition; spin; rotation; relaxation; resonance; thin; films; transition; metals; MBE; sputtering; XRR; reflectivity; molecular; beam; epitaxy; x; ray; TRIUMF; double; perovskite; longitudinal; transverse; nickel; Ni; asymmetry; positron; depolarization; chiral; lattice; helical; DM; interaction;

    Abstract : Double perovskite materials exhibit alterations in magnetic order through manipulation oftheir crystal structure. Certain ultra thin metallic bilayers can create an exotic magnetic stateof confined spin textures called skyrmions. In both cases, new atomic arrangements leadto new electrical and magnetic properties. READ MORE

  5. 19. Melting points of binary and ternary eutectic chloride salts : MD simulations on LiCl-NaCl-KCl and its binary constituents

    Keywords : Liquid metal battery; molecular dynamics; simulation; eutectic; salt;

    Abstract : This thesis investigates how well the Alexandria (WBK) force-field can predict themelting point for multi-cation chloride salts with molecular dynamic (MD) simulationsin Gromacs 4.6.7. Researched is the eutectic ternary salt LiCl-NaCl-KCl(53. READ MORE

  6. 20. Growth and Characterization of CrB2/TiB2 Superlattices by Magnetron Sputtering

    University essay from Linköpings universitet/Tunnfilmsfysik; Linköpings universitet/Tekniska fakulteten

    Author : Samira Dorri; [2019]
    Keywords : Thin films; diborides; superlattices; reflectivity; transition-metal diborides; CrB2; TiB2;

    Abstract : In the present work, growth and structural characterization of CrB2/TiB2 superlattices on (0001) Al2O3 substrate is studied. The superlattices are grown using a direct current magnetron sputtering (DCMS) system with a base pressure of <9E-7 Torr. READ MORE
