Bacteriophage removal in various clay minerals and clay-amended soils

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...

Molybdenum Adsorption on Oxides, Clay Minerals, and Soils

Molybdenum adsorption behavior was investigated on various crystalline and x-ray amorphous Al and Fe oxide minerals, clay minerals, CaC@, and arid-zone calcareous and noncalcareous s soils. Molybdenum adsorption on botb Al and Fe oxides exhibited a maximum at low pH extending to about pH 4 to 5. Above pH 5 adsorption decreased rapidly, with little adsorption occurring above pH 8. Molybdenum ads...

Detecting Clay Minerals in Soils through Hyperspectral Remote Sensing

Images of representative clayey bare fields were chosen from a high spatial resolution hyperspectral dataset that was acquired with the prototypal airborne Hyper SIM-GA sensor from Selex Galileo simultaneously with ground soil spectral signatures and the collection of samples. After both the pre-processing and calibration of the SIM-GA data, the mapping procedure was developed using the 2-2.45 ...

Clay and non-clay minerals in the pharmaceutical industry

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...
