  • The influences of cement hydration and temperature on the thixotropy of cement paste 
    Link, Julian; Sowoidnich, Thomas; Pfitzner, Christopher; Gil-Diaz, Teba; Heberling, Frank; Lützenkirchen, Johannes; Schäfer, Thorsten; Ludwig, Horst-Michael; Haist, Michael (Basel : MDPI AG, 2020)
    The rheological properties of fresh cement paste are highly influenced by a large number of parameters, among which the most important factors are the applied shear stress, and the shear history, the age of the sample and ...
  • Properties of geopolymer binders prepared from milled pond ash 
    Temuujin, J.; Minjigmaa, A.; Bayarzul, U.; Kim, D.S.; Lee, S.-H.; Lee, H.J.; Ruescher, C.H.; MacKenzie, K.J.D. (Madrid : Consejo Superior de Investigaciones Científicas (CSIC), 2017)
    Alkali-activated materials were prepared from pond ash from the Darkhan city (Mongolia) thermal power station. This ash contains about 60 wt % X-ray amorphous material in addition to quartz, mullite, hematite and ...
  • Robust methods for the decomposition and interpretation of compound dunes applied to a complex hydromorphological setting 
    Scheiber, Leon; Lojek, Oliver; Götschenberg, Axel; Visscher, Jan; Schlurmann, Torsten (New York, NY [u.a.] : Wiley, 2021)
    Underwater dunes are a morphological feature that are explored by marine scientists and coastal engineers alike. This study presents new methodologies in order to simplify bedform identification and morphodynamic analyses. ...
  • Strontium doping in mullite-type bismuth aluminate: A vacancy investigation using neutrons, photons and electrons 
    Gesing, Thorsten M.; Schowalter, Marco; Weidenthaler, Claudia; Murshed, M. Mangir; Nénert, Gwilherm; Mendive, Cecilia B.; Curti, Mariano; Rosenauer, Andreas; Buhl, Josef-Christian; Schneider, Hartmut; Fischer, Reinhard X. (Cambridge : Royal Society of Chemistry, 2012)
    We report on strontium doped dibismuth-nonaoxoaluminate(III) produced at 1023 K. Partial substitution of bismuth by strontium in the structure yields oxygen vacancies for charge balance. Introducing oxygen vacancies ...
  • Sulfur degassing at Erta Ale (Ethiopia) and Masaya (Nicaragua) volcanoes: Implications for degassing processes and oxygen fugacities of basaltic systems 
    De Moor, J.M.; Fischer, T.P.; Sharp, Z.D.; King, P.L.; Wilke, M.; Botcharnikov, Roman E.; Cottrell, E.; Zelenski, M.; Marty, B.; Klimm, K.; Rivard, C.; Ayalew, D.; Ramirez, C.; Kelley, K.A. (Hoboken, NJ : Blackwell Publishing Ltd, 2013)
    We investigate the relationship between sulfur and oxygen fugacity at Erta Ale and Masaya volcanoes. Oxygen fugacity was assessed utilizing Fe 3+/ΣFe and major element compositions measured in olivine-hosted melt inclusions ...
