NaSC2H: A First Crystalline Compound with a −SC2H Anion, an Isolobal Variant of Ubiquitous −SCN
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Crystalline NaSC2H was obtained by reacting NaC2H with elemental sulfur in liquid ammonia. It contains −SC2H anions, which was confirmed by infrared and Raman spectroscopy as well as by structural elucidation based on synchrotron powder diffraction data. −SC2H is a new isolobal variant of the ubiquitous −SCN anion (thiocyanate).

MICROTOPOCHEMISTRY AND GEOCHEMICAL FEATURES OF A PYRITE NODULE OF СARBONACEOUS SILTSTONES OF THE SAF′YANOVKA MASSIVE SULFIDE DEPOSIT (CENTRAL URAL) [PDF]
Минералогия, 2017 Pyrite nodules of carbonaceous siltstones of the Saf´yanovka nonmetamorphosed massive sulfide deposit consist of a porous poikilitic pyrite core (zone A), which is partly transformed to metacrystalline pyrite aggregates at the periphery (zones В и С ...

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 464-483, March 2025.Abstract Xenoliths in carbonaceous chondrites include lithologies that are unrepresented in the meteorite record and so are a rich source of information on asteroid diversity. Cold Bokkeveld is a CM2 regolith breccia that contains both hydrous and anhydrous lithic clasts. Here, we describe a hydrous clast with a fine‐grained rim.

Nano‐pyrite as a plant hormone regulator: Emulating seed hormopriming
Modern Agriculture‘Pre‐sowing seed priming’ and ‘pre‐transplanting root priming’ are promising strategies to improve agriculture productivity. Farmers, seed production enterprises, and seedling producers constantly search for economic priming agents that help improve ...

Magnesium phosphate in the Cold Bokkeveld (CM2) carbonaceous chondrite
Meteoritics &Planetary Science, EarlyView.Abstract Hydrous Mg‐phosphate was first described from astromaterials in particles returned from the C‐type asteroid Ryugu, and has subsequently been found in samples of the B‐type asteroid Bennu and CI1 carbonaceous chondrites. This phase may have been highly significant as a source of bioessential compounds for early Earth.

Löpönvaara: A new phosphorus‐rich iron meteorite from Finland
Meteoritics &Planetary Science, EarlyView.Abstract Löpönvaara is a rare new phosphorus‐rich iron meteorite find from Löpönvaara, Finland. The ~164 g meteorite was discovered in 2017 from the same area as the ungrouped Lieksa pallasite. Löpönvaara was classified as an ungrouped iron meteorite due to its unusually high concentration of P (>4 wt%), coupled with a moderate concentration of Ni (~11

Sedimentology, EarlyView.ABSTRACT Detailed analysis of Lutetian–Bartonian deposits in the Paris Basin (‘Marnes et Caillasses’ Formation) provides new evidence of concomitant magnesian fibrous clays (palygorskite and sepiolite) and early microcrystalline dolomite. Although relatively uncommon in sedimentary archives, palygorskite and sepiolite are found in a wide range of ...
