The microbial immobilization of zinc sulfate
Microbial immobilization of soluble zinc (ZnSO<sub>4</sub> ) as ZnS was investigated to reduce the possible hazardous effects of soluble Zn in aquatic systems. Static three-phase microcosms were designed to simulate certain characteristics of natural systems in the laboratory. Microcosms (40, 15, …

Sulfide immobilization with taconite tailings: products, capacity, and stability
… product and the determinants of overall sulfide immobilization capacity. In Chapter 3, the sulfidation of Fe-rich clays in Mesabi Select are explored further, firstly by their selective dissolution with various acids and secondly by the reactivity of these acid-treated fractions with sulfide. By …

Immobilization of Catalytic DNA for Advanced Materials and Sensors
The DNAzyme was also immobilized on patterned glass surfaces via covalent attachment. Substrate-functionalized 100 nm polystyrene particles were then hybridized in the absence and presence of Pb2+. The result was the Pb2+-mediated tethering of particles onto patterned grids, where Pb2+ induced the …
