Interaction of polyoxometalate Mo132 with poly(vinyl alcohol)

Study of acute and subacute action of iron-molybdenum nanocluster polyoxometalates

“…Unlike other prospective nanocontainers (carbon fullerenes) [7], POMs are able to decompose, forming simpler compounds of molybdenum and iron [5,6], which further participate in the metabolic processes natural for the organism.…”

“…POMs possess the following advantageous character istics: solubility in water and the ability to absorb reversibly various organic compounds [5], form com plexes [6], and move under the influence of weak elec tric fields [5].…”

Study of the stability of solid polyoxometalate Mo72Fe30 with a buckyball structure

“…The reduction of the metal ions in buckyballs in a polymer medium can occur via electron photo transfer to a polymer macro molecule. Such a process has been revealed for simpler POMs [24,25]. This process leads to buckyball destruction.…”

“…Of great importance is not only the stability of POMs in solutions but also their stability in the solid state in which they can exist in a crystalline form [3]. It is worth noting that, for the parent Мо 132 com pound, the behavior in solutions [4,5], the thermal stability and the mechanism of heat induced decom position [6,7], and the stability in polymer films exposed to UV irradiation [8] have been studied. Solid Мо 132 exhibits specific sorption properties to organic molecules [9].…”

“…In POMs, first of all in molybdenum based ones, this element can be replaced by other metals. In particular, in the POM Mo 132 [1,2] (NH 4 The substitution of ions naturally entails a change in physicochemical properties of POMs. Knowledge of trends in this change enables tailoring POMs for solving practical problems.…”
