What is it about?
Adsorption of amino acids on copper surfaces is a prototypical system for studying chiral self assembly in two dimensions. In this study we used first principles computational methods based on density functional theory to explore the effect of explicit water solvation on the mixing and phase separation of glycine and water on Cu{110}.

Why is it important?
The extent of the intermixing between glycine and water is strongly dependent on the surface temperature and on the gas pressure applied on the system. The computational results are also greatly influenced by inclusion of dispersion force interactions. The method applied in this work can be useful in predicting corrosion protection properties of surface coating systems based on small molecule self assembled overlayers.
