Ice nucleation under cirrus cloud conditions [PDF]

, 2012
Cirrus are thin upper tropospheric clouds that are composed entirely of ice particles. Due to their extensive coverage of the Earth’s surface, they have a significant impact on the Earth’s radiative balance.

Unraveling sulfur chemistry in interstellar carbon oxide ices

Nature Communications, 2022
AbstractFormyl radical (HCO•) and hydroxycarbonyl radical (HOCO•) are versatile building blocks in the formation of biorelevant complex organic molecules (COMs) in interstellar medium. Understanding the chemical pathways for the formation of HCO• and HOCO• starting with primordial substances (e.g., CO and CO2) is of vital importance in building the ...

Mechanism for the subglacial formation of cryogenic brines

Annals of Glaciology, 2022
Cryogenic brines are under-studied, despite the fact that they may contain information about past ice-sheet behavior. Cryogenic brines form through cryoconcentration of seawater, although the specific setting and mechanism of formation have been debated.

Geological and glacial-hydrologic controls on chemical weathering in the subglacial environment

Annals of Glaciology, 2022
A comparison of major ion chemistry of subglacial boreholes and discharging subglacial waters reveals three fundamentally different glacier hydrochemical regimes.

Tests of shock chemistry in IC 443G

The Astrophysical Journal, 1992
Eight molecular species, in the hot dense clump IC 443G, believed to be impacted by the shock wave from the SNR IC 443, are investigated. The clump consists of two distinct regions, one relatively cool, and one hotter and denser. Region 1 contains CO, HCO(+), HCN, and CN, whose abundances may be explained either by ion-molecule chemistry, or by a D ...
