Anion Recognition Using a Simple Cyclic Peptide
Published 2020The head-to-tail cyclic hexapeptide, [cyclo(Val-Thr)3], was found to bind to a range of anions in DMSO-d6 with higher affinity for tetrahedral oxo-anions than halides. 1H NMR spectroscopy indicated that anion binding results ...Open AccessArticle -
Soft ferromagnetism in mixed valence Sr1_ xLa xTi0.5Mn0.5O3 perovskites
Published 2014The structural, magnetic and electrical properties of the mixed Ti–Mn oxides Sr1−xLaxTi0.5Mn0.5O3 (0 ≤ x ≤ 0.5) are reported. At room temperature the oxides have a cubic structure in space group Pmm for x ≤ 0.25 and ...Article -
X-ray absorption near edge structure and crystallographic studies of the mixed valence oxide SrRu0.8Ni0.2O3
Published 2011Neutron diffraction methods are used to refine the structure of SrRu 0.8 Ni 0.2 O 3 at room temperature and 4 K. X-ray absorption measurements at the Ru L-edge demonstrate that partial oxidation of the Ru 4+ to Ru 5+ occurs ...Article -
Structural characterization of the perovskite series Sr1-xLaxTi0.5Mn0.5O3
Published 2013The perovskite-type compounds Sr{sub 1−x}La{sub x}Ti{sub 0.5}Mn{sub 0.5}O{sub 3}, x=0, 0.1, 0.2, 0.3, 0.4 and 0.5 have been synthesized by solid-state methods, and their room temperature structures determined using X-ray ...Article -
Stabilising the orthorhombic perovskite structure in SrIrO3 through chemical doping. Synthesis, structure and magnetic properties of SrIr1- x Mg x O3 (0.20≤ x≤ 0.33)
Published 2013The synthesis, structure, magnetic and electric conductivity properties of Mg doped SrIrO3 are described. Doping SrIrO3 with Mg favours an orthorhombic structure over the hexagonal face-sharing structure. Polycrystalline ...Article
