Infrared spectra of HCN/forsterite interfaces are deconvoluted by means of nonlinear best fits between experimental and computed spectra. This synergistic approach allows a reliable spectroscopic interpretation of gas-surface systems as a powerful tool to study...

Here is the second chapter of true catalysis in space! Simulations indicate that ethanol and FT by-products can form through Fischer-Tropsch synthesis in astrophysical environments by single atom Fe on silica. Fundamental and aplied knowledge at once! The presence of...

Pure sulfur is known to form several allotropes, which have lately been proposed as possible sulfur reservoir in cold clouds, where gas-phase sulfur depletion is observed. Indeed, larger species show stronger interactions with the water ice mantles of dust grains....

The binding energies of 21 N-bearing interstellar species on water ice surfaces have been computed to understand how these species are trapped in ices and their faith in protoplanetary disks by comparing the values with the water snow line Of the about 300 gas-phase...

Computations on the binding energy of H2S on interstellar water ices allow us to understand why H2S is not found as an icy species and yes as a gaseous one. The reason? The weak H2S/H2O ice interactions between the two partners! Despite hydrogen sulphide (H2S) has...
