A new high-energy density material (HEDM) 3,7-bis(dinitromethylene)- 2,4,6,8-tetranitro-2,4,6,8-tetraazabicyclo[3.3.0]octane was designed, and its physical and chemical properties were fully studied by density functional theory (DFT) method at B3LYP/6-31G (d,p) level.
Raphael NagaoI; Hamilton VarelaII,*
The emergence of self-organized structures in chemical systems kept under far from equilibrium can be described by the coupling between nonlinear kinetics and diffusive processes.
