DCB dissolution of iron oxides in aeolian dust deposits controlled by particle size rather than mineral species [PDF]
Scientific Reports, 2022 Dithionite-citrate-bicarbonate (DCB) treatment is a classical method for removing iron oxides from soil. The DCB-induced dissolution effects on iron oxides are controversial.

Unraveling iron oxides as abiotic catalysts of organic phosphorus recycling in soil and sediment matrices [PDF]
Nature CommunicationsIn biogeochemical phosphorus cycling, iron oxide minerals are acknowledged as strong adsorbents of inorganic and organic phosphorus. Dephosphorylation of organic phosphorus is attributed only to biological processes, but iron oxides could also catalyze ...

Accelerated dissolution of iron oxides in ice [PDF]
Atmospheric Chemistry and Physics, 2012 Iron dissolution from mineral dusts and soil particles is vital as a source of bioavailable iron in various environmental media. In this work, the dissolution of iron oxide particles trapped in ice was investigated as a new pathway of iron supply.

The iron-oxidizing proteobacteria [PDF]
Microbiology, 2011 The ‘iron bacteria’ are a collection of morphologically and phylogenetically heterogeneous prokaryotes. They include some of the first micro-organisms to be observed and described, and continue to be the subject of a considerable body of fundamental and applied microbiological research.

Synthesis and heating effect of iron/iron oxide composite and iron oxide nanoparticles [PDF]
SPIE Proceedings, 2007 Fe/Fe oxide nanoparticles, in which the core consists of metallic Fe and the shell is composed of Fe oxides, were obtained by reduction of an aqueous solution of FeCl3 within a NaBH4 solution, or, using a water-in-oil micro-emulsion with CTAB as the surfactant.

Formation of Iron Oxides by Surface Oxidation of Iron Plate
Croatica Chemica Acta, 2012 Oxidation of iron plates (α-phase) at high temperatures and in atmospheric conditions was monitored. The composition of oxidation products was analyzed with XRD, Raman and Mössbauer spectros-copies, whereas the morphologies of oxidation products were inspected by FE-SEM.
