Extended Data Fig. 7: Adsorption of B clusters on graphene.
From: Room-temperature hydrogen storage of boron nanoclusters

a, Structure and energy changes of B72 before and after adsorption on graphene. b, Changes in hydrogen adsorption energy of B sites after adsorption of B72 on graphene. c, Charge density difference of B72 adsorbed on graphene. The yellow and blue isosurfaces indicate electron accumulation and loss, respectively. All the results are plotted with an isovalue of 0.005 e/Bohr3. d,e, The partial density of state (PDOS) of B228@Graphene (d) and B72 (e).
