  2. 16. Crystal structures and phase equilibria in the Mn-Ga system

    Author : Magnus Boström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The Mn-Ga equilibrium phase diagram was reinvestigated. The phase analyses were performed both by powder and single crystal X-ray diffraction methods. READ MORE

  4. 17. Immunotoxicology in Marine Invertebrates - Effects of Manganese on Immune Response

    Author : Carolina A. M. Oweson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Invertebrates; Immune system; Haemocytes; Manganese Mn ; Immunotoxicology; Crustacea; Mollusca; Echinodermata;

    Abstract : Manganese, Mn, is an abundant element in nature, particularly in soft bottom sediments of the oceans and in bedrock. The metal is predominantly bound to the sediment in the colloid state, MnO2. READ MORE

  5. 18. Modulations in B8-type Intermetallics

    Author : Margareta Elding-Pontén; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron diffraction; X-ray diffraction; Superspace group; Edshammar polyhedron; Mn-Sn; Cu-In; B8-type; Ni2In; NiAs; Modulation; Superstructure; Inorganic chemistry; Oorganisk kemi;

    Abstract : The B8-type regions of the Mn-Sn and Cu-In systems have been investigated by means of electron and X-ray diffraction. The importance of the combination of these techniques in the study of B8-type phases is pointed out. In addition to the B8-type phases an alloy with a quasicrystal approximant structure has been studied. READ MORE

  6. 19. Application of the 2-Pyridone Hydrogen-Bonding Motif in Supramolecular Catalysis and in Phenanthroline Based Ligands
