  • Clays and Clay Minerals, Vol. 54, No. 1, 87-100, 2006. 
    Caillaud, J.; Proust, D.; Righi, D. (The Clay Minerals SocietyThe Clay Minerals Society, 2006)
    Under closed geochemical conditions, the weathering of a serpentinite rock composed of serpentine (70-85%) and magnesian chlorite (10-15%) associated with magnetite and chromite leads to the complete replacement of serpentine ...
  • Clays and Clay Minerals, Vol. 58, No. 1, 89–96, 2010. 
    Liu, Xiandong; Meijer, Evert Jan; Lu, Xiancai; Wang, Rucheng (The Clay Minerals SocietyThe Clay Minerals Society, 2010)
    In order to identify the influences imposed by Fe substitution, density functional theory-based Car-Parrinello molecular dynamics simulations were employed to study both oxidized and reduced Febearing smectites. The following ...
  • Clays and Clay Minerals, Vol. 58, No. 2, 164–173, 2010. 
    Aouad, Amina; Anastacio, Alexandre S.; Bergaya, Faiza; Stucki, Joseph W. (The Clay Minerals SocietyThe Clay Minerals Society, 2010)
    The placement of metal oxide pillars between clay mineral layers modifies their physicalchemical properties, including surface area, acidity, and catalytic activity. Aluminum is the most commonly used pillar cation, but ...
  • Clays and Clay Minerals, Vol. 58, No. 4, 542–557, 2010. 
    Bishop, Michael E.; Jaisi, Deb P.; Dong, Hailiang; Kukkadapu, Ravi K.; Ji, Junfeng (The Clay Minerals SocietyThe Clay Minerals Society, 2010)
    Fe-reducing micro-organisms can change the oxidation state of structural Fe in clay minerals. The interactions with complex clays and clay minerals in natural materials remain poorly understood, however. The objective of ...
  • Clays and Clay Minerals, Vol. 58, No. 5, 667–681, 2010. 
    Jodin-caumon, Marie-camille; Mosser-ruck, Regine; Rousset, Davy; Randi, Aurelien; Cathelineau, Michel; Michau, Nicolas (The Clay Minerals SocietyThe Clay Minerals Society, 2010)
    Disposal facilities in deep geological formations are considered to be a possible solution for long-term management of high-level nuclear waste (HLW). The design of the repository generally consists of a multiple-barrier ...
  • Clays and Clay Minerals, Vol. 60, No. 5, 443–455, 2012. 
    Jodin-caumon, Marie-camille; Mosser-ruck, Regine; Randi, Aurelien; Pierron, Olivier; Cathelineau, Michel; Michau, Nicolas (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    The design of the repository for high-level nuclear waste (HLW) in France consists of a multiple-barrier system including steel canisters in a clay host rock. The system will undergo temperature variations in time and ...
  • Clays and Clay Minerals, Vol. 60, No. 5, 464–472, 2012. 
    Su, Kai; Radian, Adi; Mishael, Yael; Yang, Lizhong; Stucki, Joseph W. (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    Nitrate is linked to chronic human illness and to a variety of environmental problems, and continues to be a contaminant of concern in soils and natural waters. Improved methods for nitrate abatement, thus, are still needed. ...
  • Clays and Clay Minerals, Vol. 60, No. 6, 616–632, 2012. 
    Miller, Matthew A.; Madden, Andrew S.; Madden, Megan Elwood; Elmore, R. Douglas (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    Nontronite NAu-1 was exposed to moderate temperature and pressure conditions (250 and 300ºC at 100 MPa pressure) in KCl brine to simulate burial diagenetic systems over accelerated time periods appropriate for laboratory ...
  • Clays and Clay Minerals, Vol.5 5, No.1, 89–95, 2007. 
    Komlo´si, Andrea; Kuzmann, Erno˝; Nagy, Noe´mi M.; Homonnay, Zolta´n; Kubuki, Shiro; Ko´nya, Jo´zsef (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The effect of FeCl3 in acetonic medium on the structure of Na-bentonite was studied using X-ray diffraction (XRD), 57Fe Mo¨ ssbauer spectroscopy, X-ray fluorescence spectroscopy and infrared spectroscopy to describe the ...
