Ath Godelitsas's insight:

Phosphorylation of the nucleosides adenosine and uridine by the simple mixing and mild heating of aqueous solutions of the organic compounds with synthetic analogs of the meteoritic mineral schreibersite, (Fe,Ni)3P under slightly basic conditions (pH ~9) is reported.

Scientists see deeper Yellowstone magma | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it

University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber.

CaSO4 Mineralization in Carboxy- and Amino-Functionalized Reverse Micelles Unravels Poorly Hydrated Nanophases (Bassanite)

CaSO4 Mineralization in Carboxy- and Amino-Functionalized Reverse Micelles Unravels Poorly Hydrated Nanophases (Bassanite) | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it

Organically/inorganically functionalized reverse micelles are used to rapidly establish pathways relevant to calcium sulfate mineralization in solution (including long-term stabilization of poorly hydrated phases by organic moieties, dissolution−crystallization of rounded nanocrystals and oriented attachment of nanorods).Organically/inorganically functionalized reverse micelles are used to rapidly establish pathways relevant to calcium sulfate mineralization in solution (including long-term stabilization of poorly hydrated phases by organic moieties, dissolution−crystallization of rounded nanocrystals and oriented attachment of nanorods).

Cryptomelane formation from nanocrystalline vernadite precursor

Cryptomelane formation from nanocrystalline vernadite precursor | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it


Ath Godelitsas's insight:

In the present work, the transformation of synthetic vernadite (δ-MnO 2 ) to synthetic cryptomelane under conditions analogous to those prevailing in soils (dry state, room temperature and ambient pressure, in the dark) and over a time scale of ~10 years was monitored using high-energy X-ray scattering (with both Bragg-rod and pair distribution function formalisms) and transmission electron microscopy.

Microporous gold: Comparison of textures from Nature and experiments

Microporous gold: Comparison of textures from Nature and experiments | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it
Ath Godelitsas's insight:

The paper confirms that natural microporous gold can form via the replacement of telluride minerals. This replacement may take place under hydrothermal conditions, e.g., during the late stage of the ore-depositing event, explaining the wide distribution of “mustard gold” in some deposits.

Nanodiamond polymorphs

Nanodiamond polymorphs | Mineralogy, Geochemistry, Mineral Surfaces & Nanogeoscience | Scoop.it
The unusual physical properties and formation conditions attributed to h-, i-, m-, and n-nanodiamond polymorphs has resulted in their receiving much attention in the materials and planetary science literature.
Ath Godelitsas's insight:

The authors show, using ultra-high-resolution transmission electron microscope (HRTEM) images of natural and synthetic nanodiamonds, that the diffraction features attributed to the reported polymorphs are consistent with c-diamond containing abundant defects.
