Weathering products of two fragments of Dronino iron ungrouped meteorite found in the wet and drier clay sand were studied using X-ray diffraction and Mössbauer spectroscopy with a high velocity resolution. The products of metal oxidation in the internal and external surface layers were different for both fragments. The weathering products in fragment found in the wet clay sand contain magnetit...

Introduction: Ferric sulfate pulpotomy is a safe and effective method of the pulpotomy of primary teeth. But the results of different studies indicate low success rate of ferric sulfate pulpotomy in comparison to Formocresol pulpotomy and a portion of these failures may be related to stimulating and harmful effects of zinc oxide Eugenol paste. The aim of this study was to determine and compare ...

The carcinogenic response induced in the respiratory tract of Syrian golden hamsters by repeated intratracheal instillations of benzo[a]pyrene (BP) adsorbed to ferric oxide (Fe2O3) particles suspended in saline, is shown to result from the interactions of these factors and cannula-induced tracheal wounding. Previous acute studies of intratracheal cannulation (ITC) versus intralaryngeal cannulat...

The essence of adsorbents in water or wastewater treatment cannot be over-estimated. This research paper seeks to investigate the characterisation river sand, beach sand and granite as treatment. River (collected some localities Nigeria) were sieved, washed later sun-dried. These three materials taken laboratory for XRF, SEM EDX analyses. XRF analysis revealed that oxides present selected inclu...

With the rapid growing of nanotechnology, the effects of nanomaterials released into the environment on plants have drawn more and more attention. Iron is an element essential for plant growth and development. Iron is involved in chlorophyll formation; iron deficiency will cause a plant disorder known as chlorosis. However, whether iron in nano-ferric oxide can be absorbed by plants were rarely...

Iron oxides/reduced graphene oxide composites were synthesized by facile thermochemical reactions of graphite oxide and FeSO4 · 7H2O. By adjusting reaction temperature, α-Fe2O3/reduced graphene oxide and Fe3O4/reduced graphene oxide composites can be obtained conveniently. Graphene oxide and reduced graphene oxide sheets were demonstrated to regulate the phase transition from α-Fe2O3 to Fe3O4 v...

This study discussed the performance of an integrated indirect gasification solid oxidation fuel cell (IIG-SOFC) in consideration LCA thinking. Generally, hydrogen sulfide (H2S) gasified biomass causes voltage a stack to decline over time. Although resource such as sewage sludge are carbon-neutral, SOFC creates environmental disadvantage global warming potential (GWP); such, it is necessary rem...

iron oxide (fe2o3) nanoparticles were synthesized by a simple approach using sodium borohydride (nabh4) and iron chloride hexahydrate (fecl3.6h2o). their physicochemical properties were characterized by high resolution transmission electron microscopy (hrtem), scanning electron microscopy (sem), x-ray diffraction (xrd) and electron dispersive spectroscopy (eds). xrd pattern showed that the iron...

The most important component of steelmaking slags is the iron oxide since it serves as the oxidizing agent in refining reactions. The measurement of the iron oxide content is performed in the steelworks by taking a sample out of the liquid slag, cooling it and subsequently analysing it. The procedure takes some time. It would be highly desirable, therefore, to develop methods for rapid in situ ...
