Anaerobic ammonium oxidation coupled to iron reduction in constructed wetland mesocosms.

Science of the Total Environment, 2019
Acidimicrobiaceae sp. A6 (referred to as A6) was recently identified as playing a key role in the Feammox process (ammonium oxidation coupled to iron reduction). Two constructed wetlands (CW) were built and bioaugmented with A6 to determine if, under the

Nitrogen loss through anaerobic ammonium oxidation coupled to Iron reduction from ecosystem habitats in the Taihu estuary region.

Science of the Total Environment, 2019
Anaerobic ammonium oxidation coupled to iron reduction, termed Feammox, is a new microbial process linked the nitrogen cycles. However, the nitrogen losses through Feammox from different ecosystem habitats remain unclear.

Hexavalent chromium removal by a new composite system of dissimilatory iron reduction bacteria Aeromonas hydrophila and nanoscale zero-valent iron

Chemical Engineering Journal, 2019
Core-shell Fe@Fe2O3 nanowire is one special nanoscale zero-valent iron (NZVI) with an iron core and an outside shell of iron oxide containing the surface bound ferrous ions, which has been used to remove various pollutants including Cr(VI).

Asynchronous characteristics of Feammox and iron reduction from paddy soils in Southern China.

Environmental Research
Recently, the newly discovered anaerobic ammonium oxidation coupled with iron reduction (i.e., Feammox) has been proven to be a widespread nitrogen (N) loss pathway in ecosystems and has an essential contribution to gaseous N loss in paddy soil. However,

Ferric iron reduction and iron assimilation in Saccharomyces cerevisiae

Journal of Inorganic Biochemistry, 1992
We have used the yeast Saccharomyces cerevisiae as a model organism to study the role of ferric iron reduction in eucaryotic iron uptake. S. cerevisiae is able to utilize ferric chelates as an iron source by reducing the ferric iron to the ferrous form, which is subsequently internalized by the cells.

The fate of labile organic carbon in paddy soil is regulated by microbial ferric iron reduction.

Environmental Science and Technology, 2019
Global paddy soil is the primary source of methane, a potent greenhouse gas. It is therefore highly important to understand the carbon cycling in paddy soil.

Effects of dissimilatory iron reduction on acetate production from the anaerobic fermentation of waste activated sludge under alkaline conditions.

Environmental Research, 2019
Anaerobic digestion of waste activated sludge (WAS) to produce acetate has recently attracted growing interest, while the slow hydrolytic acidification of sludge and the consumption of acetate by methanogens both decrease the yield of acetate.

Advances in iron-based electrocatalysts for nitrate reduction.

Science of the Total Environment, 2023
Excessive nitrate has been a critical issue in the water environment, originating from the burning of fossil fuels, inefficient use of nitrogen fertilizers, and discharge of domestic and industrial wastewater.

Ironing with Heavy Reduction

1984
In the conventional ironing process the maximum reduction per die is limited to 30–40 per cent due to risk of fracture in the wall at the bottom. This means that often 5 or 6 reduction steps are necessary when cups of considerable heights are produced. A theoretical analysis shows that the application of very small die angles, α= 1–4 degs.

Iron Nanoparticles Protected by Chainmail-structured Graphene for Durable Electrocatalytic Nitrate Reduction to Nitrogen.

Angewandte Chemie, 2022
The electrochemical nitrate reduction reaction (NO3RR) is an appealing technology for regulating the nitrogen cycle. Metallic iron is one of the well-known electrocatalysts for NO3RR, but it suffers from poor durability due to leaching and oxidation of ...
