Fig. 2: Angular dependence of the conformational energy landscape for alanine (Ala) in 2D nanopores.
From: Dielectric response of graphene and MoS2 nanopores in the detection of single amino acids

The conformation energy landscapes for Ala confined within graphene (a, b) and MoS2 (c, d). On the left, heatmaps of the conformational energy along the two rotational degrees of freedom represented by the angles θ and ϕ are shown. Cross sections of these along one of the angles (θ) are provided for the highest (Emax) and lowest (Emin) energy conformations are shown on the right. These insights on the conformational details are obtained by performing Step 1 in Fig. 1d.
