Layered double hydroxides (LDHs) are a class of ionic lamellar compounds made up of
positively charged brucite-like layers with an interlayer region containing charge …

Interactions between microorganisms and clay minerals are ubiquitous in nature and are
involved in the formation and transformation of clay minerals and the global cycles of many …

Acid activation is a chemical treatment traditionally used on clays, typically bentonites in
hydrochloric or sulphuric acid, to obtain partly dissolved materials with enhanced surface …

Of course such a book as we propose here is not the product of just two people working
together, although the experience has been a great pleasure for us. We would like to thank …

This review examines the atmospheric leaching (AL) of nickel laterite ores with sulphuric
acid, specifically the limonite, smectite (clay) and saprolite fractions. The kinetics and …

The concept of storing radioactive waste in geological formations calls for large quantities of
concrete that will be in contact with the clay material of the engineered barriers as well as …

Abstract Hectorite (Na 0.3 Mg 2.7 Li 0.3 Si 4 O 10 (OH) 2) is a trioctahedral clay mineral with
peculiar cation exchange capacity, surface reactivity and adsorption, and easy delamination …

Many geoscientific fields use reactive transport codes to set up and interpret experiments as
well as to understand natural processes. Reactive transport codes are also useful to give …

Soil, the “Earth's thin skin” serves as the delicate interface between the biosphere,
hydrosphere, atmosphere, and lithosphere. It is a dynamic and hierarchically organized …

Publisher Summary This chapter reviews acid treatment of smectites that are dominant
minerals in bentonites. Other products include environmentally benign catalysts or their …
