Application


  • Progress in bioleaching: fundamentals and mechanisms of microbial metal sulfide oxidation - part A: This study delves into the microbial oxidation of metal sulfides like Iron(II) sulfide, shedding light on bioleaching processes crucial for the extraction of valuable metals from ores, which is highly relevant for environmental and materials science applications (Vera et al., 2022).

  • Novel QTL Associated with Aerenchyma-Mediated Radial Oxygen Loss (ROL) in Rice: Explores genetic traits influenced by conditions such as the presence of Iron(II) sulfide in paddy fields, providing insights into how rice adapts to iron-rich anaerobic soils, which is vital for agricultural biotechnology and crop science (Duyen et al., 2022).

  • Fe(ii) and Fe(iii) dithiocarbamate complexes as single source precursors: Investigates the synthesis of nanoscale iron sulfides from these precursors, using in situ X-ray absorption spectroscopy, which is essential for developing advanced materials with specific magnetic and electronic properties (Roffey et al., 2019).

We report a facile approach to prepare carbon-coated troilite FeS (C@FeS) nanosheets via surfactant-assisted solution-based synthesis. 1-Dodecanethiol is used as both the sulfur source and the surfactant, which may form different-shaped micelles to direct the growth of nanostructures. Under appropriate

The performance of acetic acid-supported pH-heterogenized heterotrophic denitrification (HD) facilitated with ferrous sulfide-based autotrophic denitrification (AD) was investigated in upflow activated carbon-packed column reactors for reliable removal of highly elevated nitrate (42 mg NO(3)-Nl(-1)) in drinking water. The use of

Fumarate and nitrate reduction (FNR) regulatory proteins are O(2)-sensing bacterial transcription factors that control the switch between aerobic and anaerobic metabolism. Under anaerobic conditions [4Fe-4S](2+)-FNR exists as a DNA-binding homodimer. In response to elevated oxygen levels, the [4Fe-4S](2+) cluster undergoes

The iron isotope composition of sedimentary pyrite has been proposed as a potential proxy to trace microbial metabolism and the redox evolution of the oceans. We demonstrate that Fe isotope fractionation accompanies abiotic pyrite formation in the absence of Fe(II)
