This review covers the complex lower temperature chemistry of iron sulfides. Fe and S chemistry is examined in the context of iron sulfide formation processes and their kinetics with particular reference to marine systems. Three themes are followed. First, the equilibrium dynamics of the aqueous iron...

This paper shows how the structural chemistry of iron sulfides is complicated by three factors: (1) the octahedral-site Fe2+ band is overlapped by the S2:3p6 band, (2) intraatomic exchange stabilization can give rise to localized α-spin atomic moments and narrow-band β-spin electrons, ...
Acid mine drainage, produced from the oxidation of iron sulfides, often contains elevated levels of dissolved aluminum (AI), iron (Fe), and sulfate (SO 4 ) and low pH. Understanding the interactions of these elements associated with acid mine drainage is necessary for proper solid waste ...
Iron sulfides Create a Chemistry World account and you'll see fewer paywalls and get access to more free articles. One mineral form may look like gold, but Brian Clegg isn't fooled by the value of iron sulfides Ben Valsler All that glitters is not gold,...
zerovalent iron (S-nZVI), which was synthesized to enhance Pb(II) removal in aqueous solution, the S-nZVI particles exhibited a core–shell structure, with Fe0 comprising the core and iron oxides in the shell, the generated iron sulfides (FeSx) were distributed over the iron oxides shell. ...
Heather Platt, Co-Founder and Chief Battery Scientist at Platt Engineering Solutions, takes us on an expert-guided tour of battery chemistry. This conversation quickly moves us through battery chemistries like lead/acid and into more modern metal sulfides and mixed metal oxides with reversible ...
Transition metal sulfides have been regarded as promising anode materials for sodium-ion batteries (SIB). However, they face the challenges of poor electronic conductivity and large volume change, which result in capacity fade and low rate capability. In this work, a composite containing ultrasmall ...
The detailed characterizations (soft X-ray absorption spec-troscopy (sXAS), in-situ X-ray diffraction (XRD), etc.) and density functional theory (DFT) calculation demonstrate that the pinning effects built-in LiNi0.9Co0.05Mn0.05O2 materials by the dual-site occupation of iron ions on lithium ...
In this review, recent development of using transition metal sulfides such as copper sulfides, molybdenum sulfides, cobalt sulfides, and iron sulfides as electrode materials for lithium ion batteries is presented. In addition, the electrochemical reaction mechanisms and synthetic strategy of transition ...
