Synthesis and properties of magnetic iron oxide/platinum nanocomposites
2015
Iron oxide/platinum nanocomposites have been synthesized by the extractive-pyrolytic method (EPM) involving gradual decomposition of iron capronate and n-trioctylammonium hexachloroplatinate initially produced by solvent extraction. The content of platinum in the composites was 1.2 wt%, 2.4 wt% and 4.8 wt%. Phase composition, morphology and magnetic properties of the produced materials were investigated. XRD analysis and magnetic measurements show that the magnetic phase (magnetite Fe3O4) dominates in a carrier sample produced by the pyrolysis of iron carboxylate, but hematite α-Fe2O3 exists there as an admixture. Referring to the TEM results, the produced composites contain ultra-disperse …
Contact hypersensitivity to disodium hexachloroplatinate in mice.
1998
Complex platinum (Pt) compounds are known as occupational respiratory sensitizers whereas their role in skin exposure is unclear. In this study, both skin irritation and induction of contact hypersensitivity by halide Pt salts were characterized in mice. Repeated application of Na2[PtCl6] (5% in acetone) to both ears of naive BALB/c mice induced activation of the draining auricular lymph nodes. Flow cytometric analysis revealed a striking increase in the number of lymph node cells expressing proliferating cell nuclear antigen. In separate experiments, Na2[PtCl6] or acetone were applied only to the right ear of mice on 4-8 consecutive days and the animals were challenged on the left ear 6 da…
