  • Creep in reactive colloidal gels: A nanomechanical study of cement hydrates 
    Haist, Michael; Divoux, Thibaut; Krakowiak, Konrad J.; Skibsted, Jürgen; Pellenq, Roland J.-M.; Müller, Harald S.; Ulm, Franz-Jose (College Park, MD : APS, 2021)
    From soft polymeric gels to hardened cement paste, amorphous solids under constant load exhibit a pronounced time-dependent deformation called creep. The microscopic mechanism of such a phenomenon is poorly understood in ...
  • Iron oxide colloid mobility as affected by solid matrix wetting properties 
    Carstens, J.F.; Bachmann, J.; Neuweiler, I. (Washington, DC : Soil Science Society of America, 2018)
    The influence of porous media wettability on the mobility of colloids is mostly unknown. In the present work, organic-matter-coated goethite (OMCG) colloids were percolated through three saturated soil materials differing ...
  • Natural colloid mobilization and leaching in wettable and water repellent soil under saturated condition 
    Sepehrnia, Nasrollah; Fishkis, Olga; Huwe, Bernd; Bachmann, Jörg (Berlin : De Gruyter, 2018)
    The coupled transport of pollutants that are adsorbed to colloidal particles has always been a major topic for environmental sciences due to many unfavorable effects on soils and groundwater. This laboratory column study ...
