Growth and Dissolution of Minerals Using a Combination of Rare-Event Theories

Growth and Dissolution of Minerals Using a Combination of Rare-Event Theories | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it
Ath Godelitsas's insight:

Mineral growth and dissolution are often treated as occurring via a single reversible process that governs the rate of reaction. The authors show that multiple distinct intermediate states can occur during both growth and dissolution.

The mechanism of iron binding processes in erionite #zeolite fibres

The mechanism of iron binding processes in erionite #zeolite fibres | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it
Article
Ath Godelitsas's insight:
There is a clear evidence of the very limited effect of the chemical composition of erionite on the Fe(II) binding process and reasonably it does not play a significant role in its toxicity.

Impact of Mn(II)-Manganese Oxide Reactions on Ni and Zn Speciation

Impact of Mn(II)-Manganese Oxide Reactions on Ni and Zn Speciation | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it
Layered Mn oxide minerals (phyllomanganates) often control trace metal fate in natural systems. The strong uptake of metals such as Ni and Zn by phyllomanganates results from adsorption on or incorporation into vacancy sites.

Aggregation-induced growth and transformation of β-FeOOH nanorods to micron-sized α-Fe2O3 spindles

Aggregation-induced growth and transformation of β-FeOOH nanorods to micron-sized α-Fe2O3 spindles | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it
Ath Godelitsas's insight:
In this work, the authors studied the hydrothermal growth of akaganeite (β-FeOOH) nanorods and their transformation to micron-sized hematite (α-Fe2O3) spindles using high-resolution cryogenic transmission electron microscopy (cryo-TEM). Only akaganeite particles and hematite spindles were detected in the samples. Further, cryo-electron 3D tomograms show that akaganeite nanorods were aggregated into loose three-dimensional networks with some embedded hematite spindles.

High-resolution scanning- and transmission-electron microscopy of pyrobitumen-hosted uraninite reveal that uraninite grains are highly porous aggregates of uniformly sized nanocrystals, and that many of their pores are filled by native gold.

Chiral acidic amino acids induce chiral hierarchical structure in calcium carbonate

Chiral acidic amino acids induce chiral hierarchical structure in calcium carbonate | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it
Chiral structures are formed in numerous processes including biomineralization of calcium carbonate.
Ath Godelitsas's insight:
Chiral, vaterite toroidal suprastructure having a ‘right-handed’ (counterclockwise) spiralling morphology is induced by L-enantiomers of Asp and Glu, whereas ‘left-handed’ (clockwise) morphology is induced by D-enantiomers, and sequentially switching between amino-acid enantiomers causes a switch in chirality

Ath Godelitsas's insight:
The authors show that water and halogen enrichment is unexpectedly associated with trace element signatures characteristic of dehydrated oceanic crust, and that the most incompatible halogens have relatively uniform abundance ratios that are different from primitive mantle values.
