    • A new hydrate of magnesium carbonate, MgCO3·6H2O 

      Rincke, Christine; Schmidt, Horst; Voigt, Wolfgang (Acta Crystallographica Section C, 2020)
      During investigations of the formation of hydrated magnesium carbonates, a sample of the previously unknown magnesium carbonate hexahydrate (MgCO3·6H2O) was synthesized in an aqueous solution at 273.15 K. The crystal ...

    • Carbonates from the ancient world's longest aqueduct: A testament of Byzantine water management 

      Sürmelihindi, GülORCIDiD; Passchier, CeesORCIDiD; Crow, JamesORCIDiD; Spötl, ChristophORCIDiD; Mertz‐Kraus, Regina (Geoarchaeology, 2021-05-06)
      The fourth‐ and fifth‐century aqueduct system of Constantinople is, at 426 km, the longest water supply line of the ancient world. Carbonate deposits in the aqueduct system provide an archive of both archaeological ...

    • Crystal structure and characterization of magnesium carbonate chloride heptahydrate 

      Rincke, Christine; Schmidt, Horst; Buth, Gernot; Voigt, Wolfgang (Acta Crystallographica Section C, 2020)
      MgCO3·MgCl2·7H2O is the only known neutral magnesium carbonate containing chloride ions at ambient conditions. According to the literature, only small and twinned crystals of this double salt could be synthesised in a ...

    • Nano-Powdered Calcium Carbonate Reference Materials: Significant Progress for Microanalysis? 

      Jochum, Klaus PeterORCIDiD; Garbe-Schönberg, Dieter; Veter, Marina; Stoll, Brigitte; Weis, UlrikeORCIDiD; Weber, MichaelORCIDiD; Lugli, Federico; Jentzen, Anna; Schiebel, RalfORCIDiD; Wassenburg, Jasper A.; Jacob, Dorrit E.; Haug, Gerald H. (Geostandards and Geoanalytical Research, 2019)
      Homogeneity, mass fractions of about forty trace elements and Sr isotope composition of Ca carbonate reference materials (RMs) between original and nano-powdered pellets are compared. Our results using nanosecond and ...
