A (T-P) phase diagram of hydrogen storage on (N4C3H)6Li6 and the   possibility of an associated new functional material
  A temperature-pressure phase diagram has been generated through the study of hydrogen adsorption on the (N_4 C_3 H)_6Li_6 cluster at the B3LYP/6-31G(d) level of theory. Possibility of hydrogen storage in an associated 3D functional material has been also explored.
