“…only small grains). Similar results are found by Akimkin et al (2013) who used a self-consistent chemical model including dust evolution. They also find that on average, column densities of neutral molecules (e.g.…”

“…Also the impact of turbulent mixing (e.g., Semenov et al 2006;Furuya and Aikawa 2014) or dust evolution (e.g. Vasyunin et al 2011;Akimkin et al 2013) can be studied with such models. An extensive and complete review of this kind of models can be found in Henning and Semenov (2013) and Dutrey et al (2014).…”

“…In reality, the dust grains will have both a size distribution and variable dust-to-gas mass ratio caused by gravitational settling towards the midplane and dust-grain coagulation (grain growth). Several groups have also looked at the effects of dust-grain evolution on protoplanetary disk chemistry (see, e.g., Aikawa & Nomura 2006;Fogel et al 2011;Vasyunin et al 2011;Akimkin et al 2013). A parameterised treatment of grain growth affects the geometrical height of the molecular layer but appears to have little effect on the column densities of gas-phase molecules (Aikawa & Nomura 2006).…”

“…107,108 Several groups have investigated the influence of dust-grain evolution on disk chemistry. [109][110][111][112][113] The inclusion of grain growth tended to push the molecular layer deeper into the disk with increasing grain size; however, the vertical column densities of molecules remained unaffected. 110 Grain settling was found to lead to a smaller freeze out zone and a larger molecular layer due to the increased penetration of UV radiation.…”

“…111 Recent models have coupled both dust evolution processes in a disk model with full gas-grain chemistry. 112,113 In these models the chemically stratified nature of the disk is retained, albeit with a molecular layer which resides deeper into the disk. Both works also found that the gas-phase column densities are enhanced (at the expense of the grain-surface column densities) relative to the results using pristine interstellar dust.…”
