Conspectus Continuing efforts by many research groups have led to the discovery of∼ 240
species in the interstellar medium (ISM). Observatory-and laboratory-based astrochemical …

Ice is present everywhere on Earth and has an essential role in several areas, such as cloud
physics, climate change and cryopreservation. The role of ice is determined by its formation …

Restricted migration of reactive species limits chemical transformations within interstellar
and cometary ices. We report the migration of CO2 from clathrate hydrate (CH) cages to …

The existence of many molecules in the form of clathrate hydrates (CHs) in ultrahigh vacuum
(UHV) and cryogenic conditions has not been explored adequately. In the present study, a …

Acetaldehyde in a dilute aqueous solution gets hydrated to produce a geminal diol under
atmospheric conditions. The acetaldehyde–water ice system under high pressure also …

Theoretical predictions suggest that, in addition to gold (Au) and silver (Ag), several other
metals such as copper (Cu) and aluminum (Al) can be used as plasmonic materials …

This study investigated the crystal structure and composition of C2H4 hydrate, prepared from
finely powdered ice and C2H4 gas, using powder X-ray diffraction (PXRD). A …

Clathrate hydrates (CHs) are believed to exist in cold regions of space, such as comets and
icy moons. While spectroscopic studies have explored their formation under similar …

The condition for incorporating simple gases with H2O to form clathrate hydrates in
protosolar nebula is a subject of topical interest. Methane and carbon dioxide clathrate …

Although hexagonal ice (ice Ih) is the most common and highly studied crystalline form of
ice, its nucleation from clathrate hydrates is poorly understood. Here, we report the formation …
