Extended x-ray absorption fine structure—its strengths and limitations as a structural tool
TL;DR: In this article, the authors review the development of extended x-ray absorption fine structure (EXAFS) within the last decade and discuss selected examples of applications of EXAFS chosen to illustrate both the strength and limitations of this structural tool.

TL;DR: In this article, the authors introduce the concept of a geochemical switch, in which HS- transforms the marine behavior of a conservative element to that of a particle reactive element, and the action point of the HS- switch is calculated to be, a(HS)- = 10(-3.6) - 10(-4.3).

Syntheses and characterization of ammonium and tetraalkylammonium thiomolybdates and thiotungstates
TL;DR: In this paper, improved methods for the preparation of [NH4]2[MO2S2] and [NH 4 ]2[MS4] are summarized and new syntheses of [ NH 4]2 [MOS3] are reported (M = Mo, W).

Trinuclear Cuboidal and Heterometallic Cubane-Type Iron–Sulfur Clusters: New Structural and Reactivity Themes in Chemistry and Biology
TL;DR: The cuboidal and heterometal cubane-type species afford new structural and reactivity themes in both inorganic chemistry and biology as discussed by the authors, which is well supported by consideration of just four of the major discoveries in the field in the last decade.
