Interactions of Clay Minerals with Organic Polymers. Some Practical Applications

An account is given of the interactions between clay minerals and organic polymers with particular reference to their applications in agriculture, foundation engineering and industry.

Ore Minerals under the Microscope

THE student of geology in the course of his training usually passes through three stages of achievement: A first in which he learns to identify the materials with which he works; a second in which he learns to recognize the distribution of these materials in space; and a third in which, from this distribution, he interprets the geologic history of the area of the assemblage of materials. Paraph...

Clay Minerals and Catalysis

More than half a century ago, Irish physicist John Desmond Bernal and Swiss geochemist Victor M. Goldschmidt independently proposed that clay minerals may have played an important role in prebiotic synthesis (Bernal 1949; Goldschmidt 1952). I concur that mineral catalysis must have had a central role in prebiotic synthesis because most uncatalyzed reactions start from simple precursors like hyd...

Clay Minerals: Adsorbophysical Properties

The structure and features of surfaces of clay minerals (kaolin, montmorillonite, etc) have an important scientific and practical value. On the surface the interrelation of processes at electronic, atomic and molecular levels is realized. Availability of mineral surface to external influences opens wide scientific and technical opportunities of use of the surface phenomena, so the research of c...
