  • Clays and Clay Minerals, Vol. 56, No. 3, 338–343, 2008. 
    Kaufhold, Stephan; Dohrmann, Reiner; Koch, Dietrich; Houben, Georg (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    The pH of aqueous bentonite suspensions is known to be influenced by carbonates present even in minor amounts. On the other hand, at high solid:liquid ratios (at standard pH measurement conditions: 2% w/w suspension), the ...
  • Clays and Clay Minerals, Vol. 56, No. 6, 686–692, 2008. 
    Kaufhold, Stephan; Dohrmann, Reiner (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    A method for the determination of the water-uptake capacity of powders which is said to be applicable to viscose silk, specific celluloses, soap, paint, glue, gelatine, adhesives based on starch, biological samples, and ...
  • Clays and Clay Minerals, Vol. 57, No. 1, 72–81, 2009. 
    Kaufhold, Stephan; Kaufhold, Annette; Jahn, Reinhold; Brito, Salomon; Dohrmann, Reiner; Hoffmann, Rainer; Gliemann, Hartmut; Weidler, Peter; Frechen, Manfred (The Clay Minerals Society, 2009)
    In Ecuador, DINAGE (known today as the Servicio Geolo´gico Nacional) and the German Federal Institute for Geosciences and Natural Resources have discovered a huge allophane deposit covering an area of >4000 km2. This study ...
  • Clays and Clay Minerals, Vol. 58, No. 1, 79–88, 2010. 
    Dohrmann, Reiner; Kaufhold, Stephan (The Clay Minerals SocietyThe Clay Minerals Society, 2010)
    The aim of the present study was to find methodological tools to obtain reasonable results for exchangable Ca2+ of gypsiferous bentonites. Cation exchange capacity (CEC) is an important property of clays. Numerous methods ...
  • Clays and Clay Minerals, Vol. 58, No. 5, 707–716, 2010. 
    Kaufhold, Stephan; Ufer, Kristian; Kaufhold, Annette; Stucki, Joseph W.; Anastacio, Alexandre S.; Jahn, Reinhold; Dohrmann, Reiner (The Clay Minerals SocietyThe Clay Minerals Society, 2010)
    Allophane is a very fine-grained clay mineral which is especially common in Andosols. Its importance in soils derives from its large reactive surface area. Owing to its short-range order, allophane cannot be quantified by ...
  • Clays and Clay Minerals, Vol. 59, No. 2, 200–211, 2011. 
    Kaufhold, Stephan; Dohrmann, Reiner; Stucki, Joseph W.; Anastacio, Alexandre S. (The Clay Minerals Society, 2011)
    The layer charge density (LCD) of montmorillonite represents the permanent negative charge, its most important property. The LCD can be determined by two different methods, the structural formula method(SF M) and the ...
  • Clays and Clay Minerals, Vol. 60, No. 2, 162–175, 2012. 
    Dohrmann, Reiner; Genske, Dieter; Karnland, Ola; Kaufhold, Stephan; Kiviranta, Leena; Olsson, Siv; Plotze, Michael; Sanden, Torbjorn; Sellin, Patrik; Svensson, Daniel; Valter, Martin (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    Bentonites are candidate materials for encapsulation of radioactive waste. The cation exchange capacity (CEC) has proved to be one of the most sensitive parameters for detecting changes of mineral properties such as swelling ...
