“…The conversion of oxygen and the production of all these compounds is much lower on U than on P. Iron impurities could have a role in ethanol oxidation, taking into account the well known catalytic activity of FeOx/Al2O3 catalysts in oxidation reactions [35]. The activity of "pure" alumina as a catalyst for total oxidation is relevant with respect to its application as support for partial oxidation catalysts.…”

“…The prevalence of iron in nature, in its various oxidized forms, in combination with low extraction costs, has made finding potential applications for iron oxide nanoparticles (IONPs) highly attractive. Increasingly, novel applications for iron oxides are under investigation as researchers study IONPs as potential drug delivery systems [ 4 ], hyperthermia agents [ 5 ], magnetic resonance imaging contrast agents [ 5 , 6 ] catalysts for environmental remediation, and much more [ 7 , 8 , 9 , 10 , 11 , 12 ]. The array of applications associated with IONPs is a result of their tunable properties.…”

In recent years, there has been an increased interest in the design and use of iron oxide materials with nanoscale dimensions for magnetic, catalytic, biomedical, and electronic applications. The increased manufacture and use of iron oxide nanoparticles (IONPs) in consumer products as well as industrial processes is expected to lead to the unintentional release of IONPs into the environment. The impact of IONPs on the environment and on biological species is not well understood but remains a concern due to the increased chemical reactivity of nanoparticles relative to their bulk counterparts. This review article describes the impact of IONPs on cellular genetic components. The mutagenic impact of IONPs may damage an organism’s ability to develop or reproduce. To date, there has been experimental evidence of IONPs having mutagenic interactions on human cell lines including lymphoblastoids, fibroblasts, microvascular endothelial cells, bone marrow cells, lung epithelial cells, alveolar type II like epithelial cells, bronchial fibroblasts, skin epithelial cells, hepatocytes, cerebral endothelial cells, fibrosarcoma cells, breast carcinoma cells, lung carcinoma cells, and cervix carcinoma cells. Other cell lines including the Chinese hamster ovary cells, mouse fibroblast cells, murine fibroblast cells, Mytilus galloprovincialis sperm cells, mice lung cells, murine alveolar macrophages, mice hepatic and renal tissue cells, and vero cells have also shown mutagenic effects upon exposure to IONPs. We further show the influence of IONPs on microorganisms in the presence and absence of dissolved organic carbon. The results shed light on the transformations IONPs undergo in the environment and the nature of the potential mutagenic impact on biological cells.

“…Also, strongly clustered iron oxides are reported as active catalysts for soot oxidation [15]. However, for practical long-term performance, the susceptibility of Fe/Al 2 O 3 to sulphur poisoning has to be taken into account; the desulphurisation of such catalysts seems feasible [16,17].…”
