The colloidal chemistry of ceramic clays [PDF]

open access: yes
The colloidal chemistry and mineralogy of two argil minerals were studied. Deposits of kaolin and of ceramic clays in the United States and England are discussed for the probable mechanism of formation.

Spectral (MIR) determination of kaolinite and gibbsite contents in lateritic soils [PDF]

open access: yes, 1995
Kaolinite et gibbsite sont, avec les oxyhydroxydes de fer et le quartz, les constituants de base des sols latéritiques. Les proportions relatives de ces deux minéraux sont des témoins du degré d'évolution de ces sols, d'où l'intérêt de leur détermination

Phase behaviour of binary mixtures of diamagnetic colloidal platelets in an external magnetic field

open access: yes, 2011
Using fundamental measure density functional theory we investigate paranematic-nematic and nematic-nematic phase coexistence in binary mixtures of circular platelets with vanishing thicknesses.
