Observations by ISO and Spitzer towards young stellar objects (YSOs) showed that CO$_2$ segregates in the icy mantles covering dust grains. Thermal processing of ice mixture was proposed as responsible for the segregation. Although several laboratory studied thermally induced segregation, a satisfying quantification is still missing. We propose that the diffusion of CO$_2$ along pores inside water ice is the key to quantify segregation. We combined Temperature Programmed Desorption (TPD) and… 
Characterization of thin film CO2 ice through the infrared ν1 + ν3 combination mode
Carbon dioxide is abundant in ice mantles of dust grains; some is found in the pure crystalline form as inferred from the double peak splitting of the bending profile at about 650 cm$^{-1}$. To study
Diffusion of CH4 in amorphous solid water
Context. The diffusion of volatile species on amorphous solid water ice affects the chemistry on dust grains in the interstellar medium as well as the trapping of gases enriching planetary
Measurements of Diffusion of Volatiles in Amorphous Solid Water: Application to Interstellar Medium Environments
The diffusion of atoms and molecules in ices covering dust grains in dense clouds in interstellar space is an important but poorly characterized step in the formation of complex molecules in space.
The 12CO2 and 13CO2 Absorption Bands as Tracers of the Thermal History of Interstellar Icy Grain Mantles
Analyses of infrared signatures of CO$_2$ in water dominated ices in the ISM can give information on the physical state of CO$_2$ in icy grains and on the thermal history of the ices themselves. In
Experimental study of the penetration of oxygen and deuterium atoms into porous water ice
Context. Many interstellar molecules are thought to form on dust grains. In particular, hydrogenation is one of the major mechanisms of the formation of mantle ice. To date it is not clear if H atoms
Desorption of N2, CO, CH4, and CO2 from interstellar carbonaceous dust analogues
The interaction of volatile species with carbonaceous interstellar dust analogues is of relevance in the chemistry and physics of dense clouds in the interstellar medium. Two deposits of
Experimental study of desorption and reactivity of nitrogen bearing species on interstellar dust grains
The interstellar medium is a key component of galaxies which is the matrixof the formation of stars and planets. It is composed of interstellar gas and dust grains. The presence of complex organic
Spectroscopic measurements of CH3OH in layered and mixed interstellar ice analogues
Context. The molecular composition of interstellar ice mantles is defined by gas-grain processes in molecular clouds, with the main components being H2O, CO, and CO2. Methanol (CH3OH) ice is detected
Phase Transition of Interstellar CO Ice
Among the over 200 molecular species identified in interstellar clouds, many are organic molecules. It has been proposed that some of these molecules survive the star and planet formation process and

CO diffusion into amorphous H2O ices
The mobility of atoms, molecules and radicals in icy grain mantles regulate ice restructuring, desorption, and chemistry in astrophysical environments. Interstellar ices are dominated by H2O, and
Adsorption of CO on amorphous water-ice surfaces
We present the results of classical trajectory calculations of the adsorption of thermal CO on the surface of compact amorphous water ice, with a view to understanding the processes governing the
Formation of interstellar solid CO{_2} after energetic processing of icy grain mantles
Context. Space infrared observations with ISO-SWS and Spitzer telescopes have clearly shown that solid carbon dioxide (CO2 )i s ubiquitous and abundant along the line of sight to quiescent clouds and
Carbon dioxide segregation in 1:4 and 1:9 CO2:H2O ices
Abstract The mid-infrared spectra of mixed vapor deposited ices of CO 2 and H 2 O were studied as a function of both deposition temperature and warming from 15 to 100 K. The spectra of ices deposited
Interactions of adsorbed CO₂ on water ice at low temperatures.
TLDR
A new H2O-CO2 interaction potential is proposed and used to model the ballistic deposition of CO2 layers on water ice surfaces, and to study the individual binding sites at low coverages.
Porosity and thermal collapse measurements of H2O, CH3OH, CO2, and H2O:CO2 ices.
TLDR
The amount of compaction for four different ices upon heating over an astronomically relevant temperature regime is discussed and it is found that thermal segregation benefits from a higher degree of porosity.
Diffusion measurements of CO, HNCO, H2CO, and NH3 in amorphous water ice
Context. Water is the major component of the interstellar ice mantle. In interstellar ice, chemical reactivity is limited by the diffusion of the reacting molecules, which are usually present at
Binding Energy of Molecules on Water Ice: Laboratory Measurements and Modeling
We measured the binding energy of N$_2$, CO, O$_2$, CH$_4$, and CO$_2$ on non-porous (compact) amorphous solid water (np-ASW), of N$_2$ and CO on porous amorphous solid water (p-ASW), and of NH$_3$

TLDR
The results allow us to rule out the presence of pure and amorphous CO2 ice in space based on the observations available so far, supporting the current view of the evolution ofCO2 ice.
Thermal desorption characteristics of CO, O2 and CO2 on non‐porous water, crystalline water and silicate surfaces at submonolayer and multilayer coverages
The desorption characteristics of molecules on interstellar dust grains are important for modelling the behaviour of molecules in icy mantles and, critically, in describing the solid–gas interface.
