TL;DR: In this article, the absolute energy positions of conduction and valence band edges were compiled for about 50 each semiconducting metal oxide and metal sulfide minerals, and the relationship between energy levels at mineral semiconductor-electrolyte interfaces and the activities of these minerals as a catalyst or photocatalyst in aqueous redox reactions were reviewed.

TL;DR: Real-space fitting indicates structural relaxation with decreasing particle size and also suggests that second-order effects such as internal strain, stacking faults, and particle shape contribute to the PDFs.

TL;DR: In this paper, the formation of pyrite and marcasite from a FeS precursor has been examined experimentally and it was shown that pyrites and Marcasite formation proceed at a significant rate only if intermediate sulfur species (i.e., polysulfides, polythionates, or thiosulfate) are present in solution.

TL;DR: Four common techniques for the removal of dissolved oxygen from water have been examined: boiling at 1 atm, boiling under reduced pressure, purging with N(2) and sonication under reducing pressure.

TL;DR: In this article, reaction paths for nucleation and growth of pyrite and marcasite from solution have been investigated experimentally, and conditions were chosen to avoid the precipitation of metastable Fe-S phases which can act as precursors for FeS2 formation.
