A large fraction of interstellar carbon is locked up in solid grains. The nature, origin and
evolution of these grains have been investigated for decades. A combination of …

Evolved stars are foundries of chemical complexity, gas and dust that provide the building
blocks of planets and life, and dust nucleation first occurs in their photosphere. The …

Interstellar carbonaceous dust is mainly formed in the innermost regions of circumstellar
envelopes around carbon-rich asymptotic giant branch stars (AGBs). In these highly …

Context. Carbonaceous cosmic dust is observed through infrared spectroscopy either in
absorption or in emission. The details of the spectral features are believed to shed some …

We developed a new analytical experimental setup called AROMA (Astrochemistry
Research of Organics with Molecular Analyzer) that combines laser desorption/ionization …

Green synthesis of nanocarbons from greenhouse gas CO 2 has been achieved by
introducing lithium hydride into CO 2 system. However, the role of lithium hydride in …

Carbon because of its electronic structure can formulate several types of bonds and
allotropes. In the ranking of elements in the Universe, carbon is the fourth most abundant …

The impact of high enthalpy shock wave on graphitic carbon nanoparticle (GCNP) films has
been investigated and discussed in view of space and chemical engineering applications …

We report a synthesis of hydrogenated carbon nanospheres (HCNSs) via a facile
solvothermal route at low temperatures (60–100° C), using CHCl3 as the carbon source and …

Here, we present the results of the first solid-phase ex situ analysis of cosmic grain analogs
produced at low temperature (< 200 K) in the NASA Ames COsmic SImulation Chamber …
