Pedogenic Forms of Iron in Soils Developed from Four Parent Materials

open access: yesJournal of Tropical Soils, 2020
Information on the distribution of various forms of iron in soils are valuable in the study of soil genesis. The objective of this study was to to evaluate the pedogenic forms of iron in soils developed over basement complex and basaltic parent materials

Selectivity of soil constituents by termites in the construction of Brazilian termite mounds [PDF]

open access: yesScientia Agricola, 2023
Termites can create structures that alter the physical and chemical properties of soils. In this process, termites are selective about the soil constituents they will use to construct their mounds.

The iron-oxidizing proteobacteria [PDF]

open access: yesMicrobiology, 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.

Corrosion Behavior of Pipeline Carbon Steel under Different Iron Oxide Deposits in the District Heating System

open access: yesMetals, 2017
The corrosion behavior of pipeline steel covered by iron oxides (α-FeOOH; Fe3O4 and Fe2O3) was investigated in simulated district heating water. In potentiodynamic polarization tests; the corrosion rate of pipeline steel is increased under the iron oxide

The association of cobalt with iron and manganese (oxyhydr)oxides in marine sediment. [PDF]

open access: yes, 2010
Formation and dissolution of authigenic Fe and Mn (oxyhydr)oxides influence cycling of trace metals in oxic/suboxic surface sediments.We used the diffusive gradients in thin films technique (DGT) to estimate the association of cobalt with iron and ...

Synthesis and heating effect of iron/iron oxide composite and iron oxide nanoparticles [PDF]

open access: yesSPIE 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.

Modeling the iron oxides and oxyhydroxides for the prediction of environmentally sensitive phase transformations

open access: yes, 2011
Iron oxides and oxyhydroxides are challenging to model computationally as competing phases may differ in formation energies by only several kJ/mol, they undergo magnetization transitions with temperature, their structures may contain partially occupied ...
