Hematite reaction with tar to produce carbon/iron composites for the reduction of Cr(VI) contaminanic highly dispersed on the Fe surface. The composites obtained at 800°C showed high efficiency to reduce Cr(VI) as CrO. in aqueous medium with much better results compared to finely ground commercial Fe°.

Supported iron based redox systems for hydrogen production and storage from ethanol,er the reactions it was interesting to observe that ethanol can directly reduce the iron oxide to produce metallic iron, with carbon deposition and iron–carbon as side product. Preliminary results indicate that it is possible to perform multiple redox cycles with the supported iron oxide without deactivation.

,57Fe Mössbauer spectroscopy of radiation damaged samarskites and gadolinites,0. α-decay/mg for one of the samarskite samples. The Mössbauer spectra of samarskites and gadolinites show increasing line widths of the Fe. doublets with absorbed α-dose. We also observe that the increase in average quadrupole splitting of the Fe. cmponents correlates better with absorbed α-dose from .Th than with total α-dose.

Characterization of corrosion products of a carbon steel screw-nut set exposed to mountain weather emperature and 15 K were performed, detecting a great quantity of goethite but also lepidocrocite, hematite, magnetite and maghemite. This study was complemented by material characterization in terms of chemical composition, microscopic observation and X-ray diffraction analysis.
