INFRA-ICE: SIMULATING THE COSMIC DUST-ICE INTERACTION IN THE INTERSTELLAR MEDIUM (REV. SCI. INSTRUM. 2020)

  The last module of Stardust, INFRA-ICE, is ready! This module is dedicated to simulate the chemistry taking place in the densest regions of the interstellar medium, the so-called dense molecular clouds. As such, INFRA-ICE expands the capabilities of Stardust allowing for the complete journey of cosmic dust to be…

On the origin of interstellar aromatic molecules

Despite their abundance and ubiquity in space, the origin of polycyclic aromatic hydrocarbons (PAHs) is still a mystery for astronomers. Gas phase chemistry models, this is, simple collisions between C atoms and C-containing molecules, and soot formation mechanisms can not easily account for the observed amount of PAHs, as they…

Interplay between fast diffusion and molecular interaction in the formation of self-assembled nano-structures of S-Cysteine on Au(111)

Fast diffusing cysteine molecules on the Au surface can be regarded as a 2D molecular gas. Molecular “evaporation” and “condensation” from the gas on the surface morphological features takes place continuously. This process leads progressively to the formation of a number of stable arrangements, not previously reported, like single-molecular rows,…
