Speciation in Metal Toxicity and Metal-Based Therapeutics

Metallic elements, ions and compounds produce varying degrees of toxicity in organisms with which they come into contact. Metal speciation is critical to understanding these adverse effects; the adjectives "heavy" and "toxic" are not helpful in describing the biological properties of individual elements, but detailed chemical structures are. As a broad generalization, the metallic form of an el...

Metal speciation in environmental and biological systems.

Metal ions form complexes with naturally occurring complexing agents or ligands released from industrial activity. The metal complexes are thereby mobilized and transported in environmental and biological systems. The impact of such metal complexes depends on the metal complex species that are kinetically and thermodynamically stable in these homogeneous and heterogeneous systems. The distribut...

Metal Bioavailability and Speciation in a Wetland

Reversible halide-modulated nickel-nickel bond cleavage: metal-metal bonds as design elements for molecular devices.

The synthesis and study of basic molecular devices are active areas of research aimed toward understanding the fundamental design and functional parameters required for the construction of complex molecular machines.[1] Transition metals have been used extensively in this context in conjunction with elegantly designed ligand frameworks.[2] Typically, transition metals bind to different sets of ...

Cement augmentation in fracture treatment.

Surgical treatment of fractures close to joints, especially in osteoporotic patients, is often associated with problems to obtain adequate strength of the bone-implant construct as well as sufficient purchase for screws in the weak bone. One way to address this increasing problem is through the development of new metal implants specifically designed for fixation of fractures in osteopenic bone....
