### Amorphous Ice and Dust In the interstellar medium

Amorphous ice and dust grains in the interstellar medium catalyze many important astrochemical and astrophysical reactions. We use molecular dynamics to simulate molecule/ice collisions and predict molecular sticking probabilities. This figure illustrates our simulated amorphous ice slab at 10 K, with red and gray balls representing oxygen and hydrogen atoms, respectively. (Stancil/Lewis collaboration)
