Trace element composition of troilite, iron and iron-nickel metall from meteorite Chelyabinsk
Литосфера, 2015 We studied the contents of trace elements in troilite, iron and in iron-nickel metal from meteorite Chelyabinsk by means of LA-ICP-MS. The features of the distribution of siderophile and chalcophile elements in sulfide and metallic phase in gray and ...

Size‐Dependent Segregation in SiC Nanostructures: From 0D Clusters to 2D Monolayers
Small Structures, Volume 7, Issue 10, October 2026.The energetic competition between alternating Si─C bonding and Si/C segregation across 0D, 1D, and 2D nanostructures is compared. Si/C segregation is favored at smaller sizes (e.g., nanoparticles), but Si─C alternation becomes preferred for systems containing a few hundred atoms (e.g., nanotubes and 2D sheets). This size‐dependent crossover is found to

Ceres' Salty Ices: Sublimation‐Driven Evolution From Water Ice Exposures to Na‐Carbonate Deposits
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract The dwarf planet Ceres hosts nine geologically recent water ice exposures revealed by NASA's Dawn mission. We investigated the 0.04–11 km2 sites using visible imagery and infrared (1.0–4.3 μm) reflectance spectroscopy. Ice occurrence was mapped, and its abundance, grain size, and mixing mode with local regolith were constrained with Hapke ...

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract Ammonium (NH4+) in the interlayer space of phyllosilicates has been proposed as a potential but underexplored nitrogen reservoir on Mars. We synthesized ammonium‐exchanged smectites (montmorillonite SWy‐2 and nontronite NAu‐2) and analyzed them, both as pure phases and in mixtures containing five or 20 wt.% magnesium (Mg) perchlorate, under ...
