β-Cyclodextrin Immobilized in Geophagic Clay Sheets for the Absorption of Dyes From Wastewater Using a Fixed-Bed Method. [PDF]
Water Environ Resβ‐Cyclodextrin‐functionalized geophagic clay was applied in a fixed‐bed column for the removal of rhodamine B (RhB) and methyl orange (MO). RhB interacts via electrostatic attraction and hydrogen bonding, while MO undergoes cavity inclusion complexation and hydrogen bonding within the βCD structure.

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Thermal-mechanical properties of polyurethane-clay shape memory polymer nanocomposites [PDF]
, 2010 Shape memory nanocomposites of polyurethane (PU)-clay were fabricated by melt mixing of PU and nano-clay. Based on nano-indentation and microhardness tests, the strength of the nanocomposites increased dramatically as a function of clay content, which is

Polymer-clay Nanocomposites [PDF]
, 2004 PhDPolymer-clay nanocomposites are attracting global interest principally because property enhancements are obtained at low clay particle loadings (1-5 wt%). However there is lack of fundamental understanding of such composites.

A Simple Diffractometer Heating-Cooling Stage: Application to the Study of an Organo-Clay Complex [PDF]
Clays and Clay Minerals, 1991 The study of the intercalation of organic compounds into clays, as in the preparation of pillared clays, is of great importance both from the theoretical point of view and for its applications in pharmacy, agriculture, clay characterization, catalysis, etc. (MacEwan and Wilson, 1980; Theng, 1974; Pinnavaia, 1983).

Adsorption of Uranium on Organo-clay Complex.
RADIOISOTOPES, 1991 種々のアルキルアミンとウランとのイオン会合体をフロック状粘土有機複合体に吸着させてウランを捕集した。イオン対形成剤には第四級アンモニウムであるゼフィラミンがウランに対して良い吸着率を示したので, ゼフィラミンとウランとのモル比を, pHを変えて調べ, 生成した吸着物 (以下, 吸着物と略称する) の組成とウランの吸着率を検討した。その結果, 吸着率はpH6-8で最大値を示し, その会合体には4・zephyramine・UO2 (CO3) 3が含まれていることが分かった。
