11 p, 2.1 MB Swelling behavior of Na- and Ca-montmorillonite up to 150°c by in situ x-ray diffraction experiments / Morodome, Shoji (Tokyo Institute of Technology. Department of Earth and Planetary Science) ; Kawamura, Katsuyuki (Tokyo Institute of Technology. Department of Earth and Planetary Science)
The effects of temperature on the swelling properties of smectites are important for a variety of different geological conditions, but studies on this topic have been rather limited. The purpose of this study was to investigate the swelling behavior of Na- and Ca-montmorillonite at various temperatures greater than room temperature, up to 150°C, using in situ X-ray diffraction (XRD) analysis. [...]

Laboratory of Applied Clay Technology) ; Kawamura, Katsuyuki (Tokyo Institute of Technology. Department of Earth and Planetary Sciences)
An organophilic bentonite was prepared by means of a reaction of natural Na-montmorillonite with trimethyldococylammonium which has an especially long n-alkyl chain. The addition of trimethyldococylammonium to montmorillonite was in the range 0. [...]

11 p, 749.2 KB In situ X-ray diffraction study of the swelling of montmorillonite as affected by exchangeable cations and temperature / Morodome, Shoji (Kunimine Industries Co. Research Laboratories) ; Kawamura, Katsuyuki (Okayama University. Graduate School of Environmental Science)
The swelling property of smectite is dominated by the hydration of exchangeable cations in the interlayer spacing ('interlayer hydration'). By investigating systematically the swelling behavior of various exchangeable cations with different valences and ionic radii, the interlayer hydration of smectite was explored. [...]

Measurements of the UK'37 index and the absolute abundance of alkenones in marine sediments are increasingly used in paleoceanographic research as proxies of past sea surface temperature and haptophyte (mainly coccolith-bearing species) primary productivity, respectively. [...]
