Fig. 1From: Competitive and/or cooperative interactions of graphene-family materials and benzo[a]pyrene with pulmonary surfactant: a computational and experimental studySystematic scan of the BaP agglomeration and adsorption on GFMs. a–f Simulated aggregates of BaPs of different numbers. g–l Adsorption of dispersed BaPs on graphene. m–r Adsorption of aggregated BaPs on graphene. The number of BaPs is respectively 40 (a, g, m), 80 (b, h, n), 120 (c, i, o), 160 (d, j, p), 200 (e, k, q) and 240 (f, l, r). s–x Adsorption of 80 (s, t), 200 (u, v) and 240 (w, x) BaPs respectively in dispersed (s, u, w) and agglomerated (t, v, x) states on graphene oxide. In each snapshot, BaPs are displayed in black, graphene nanosheet is displayed in blue, and red points represent graphene oxidationBack to article page
