    • Investigation of the hydrothermal crystallisation of the perovskite solid solution NaCe1-xLaxTi2O6 and its defect chemistry 

      Harunsani, Mohammad H.; Woodward, David I.; Peel, Martin; Ashbrook, Sharon Elizabeth Marie; Walton, Richard I. (2013-11) - Journal article
      Perovskites of nominal composition NaCe1−xLaxTi2O6 (0≤x≤1) crystallise directly under hydrothermal conditions at 240 °C. Raman spectroscopy shows distortion from the ideal cubic structure and Rietveld analysis of powder ...
    • Mars analogue glaciovolcanic hydrothermal environments in Iceland : detection and implications for astrobiology 

      Cousins, Claire Rachel; Crawford, Ian; Carrivick, Jonathan; Gunn, Matthew; Harris, Jennifer; Kee, Terence; Karlsson, Magnus; Carmody, Laura; Cockell, Charles; Herschy, Barry; Joy, Katherine (2013-04-15) - Journal article
      Volcanism has been a dominant process on Mars, along with a pervasive global cryosphere. Therefore, the interaction between these two is considered likely. Terrestrial glaciovolcanism produces distinctive lithologies and ...
    • Scandium bearing open framework materials 

      Miller, Stuart R. (University of St Andrews, 2007-12-17) - Thesis
      Here I report the hydrothermal chemistry of scandium, examining the behavior of the Sc³⁺ cation in various systems, including phosphates, phosphites, phosphonates and carboxylates. In total, 27 different materials, 23 of ...
    • The solvothermal synthesis of early transition metal fluorides 

      Aldous, David W. (University of St Andrews, 2008-03-05) - Thesis
      In this thesis, 60 crystal structures which have been synthesised by the solvothermal method are reported, with 57 of them representing novel materials. The remaining three materials have previously been reported but have ...
    • Synthesis and structure-property relationships in selected metal fluorides 

      Reisinger, Sandra A. (University of St Andrews, 2012-06) - Thesis
      There has been an increase in the interest in fluoride materials over the last decade. This interest has focused on multiferroic materials and kagome lattices, to name but a few areas. This thesis focuses on the synthesis ...
    • Synthesis, adsorption and catalysis of large pore metal phosphonates 

      Pearce, Gordon M. (University of St Andrews, 2010-06) - Thesis
      The synthesis and properties of metal phosphonates prepared using piperazine-based bisphosphonic acids have been investigated. The ligands N,N’-piperazinebis(methylenephosphonic acid) (H₄L), and the 2-methyl (H₄L-Me) and ...
