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,…
