Journal ArticleDOI
Structure of synthetic monoclinic Na-rich birnessite and hexagonal birnessite; I, Results from X-ray diffraction and selected-area electron diffraction
TL;DR: In this article, a structural model for synthetic Na-rich birnessite (NaBi) and its low pH form, hexagonal BnBi (HBi) was proposed, based on X-ray and selected-area electron diffraction (XRD, SAED).
Journal ArticleDOI
Structure of synthetic monoclinic Na-rich birnessite and hexagonal birnessite: II. Results from chemical studies and EXAFS spectroscopy
TL;DR: In this paper, Drits et al. showed that lattice cation vacancies are of critical importance in adsorption and electron transfer processes occurring at the surface of Na-rich birnessite.
Journal ArticleDOI
Structural mechanism of Co (super 2+) oxidation by the phyllomanganate buserite
TL;DR: In this article, two distinct oxidation mechanisms were identified that occur concurrently with the transformation of low pH monoclinic buserite to hexagonal H-rich birnessite.
Journal ArticleDOI
Structure of H-exchanged hexagonal birnessite and its mechanism of formation from Na-rich monoclinic buserite at low pH.
TL;DR: The structural transformation of high pH Na-rich buserite (NaBu) to H-exchanged hexagonal birnessite (HBi) at low pH was studied by simulation of experimental X-ray diffraction patterns.

TL;DR: In this article, the authors identified the 10 major terrestrial and marine ecosystems in Australia most vulnerable to tipping points, in which modest environmental changes can cause disproportionately large changes in ecosystem properties.
