Abstract: |
The main result of our theoretical investigations started in 1997 is the prediction of a possibility of the existence of ensembles composed of N8 clusters (so-called "boats"), i.e., a condensed phase formed from the N8 clusters as from "bricks".
We have shown that this new nanomatter can accumulate the energy 3-4 times greater than the best "chemical" energy materials; it can be stable under normal pressure and heating up to 800 K. We have also found that the energy release from nitrogen clusters upon their fission into N2 molecules occurs completely and in a very short time. We have shown that the process of the energy release from non-molecular nitrogen is fundamentally different from the process of the energy release from "chemical" energy carriers where it takes place upon synthesis of fuel and oxidant.
The quantum calculations of the nitrogen clusters and their ensembles for various configurations are presenteded. The most stable ensemble configurations of the clusters N8 (boat) are found. The pieces of Gosh phase, tree-dimensional ensembles of the clusters N8 ("boats"), and also their periodical three-dimensional structures are found too. Every possible isomers of cluster N4 with various multiplicities and the space symmetries for the purpose of optimisation of process of their synthesis are explored. Equilibrium geometries and energies for all explored isomers within the limits of the MCSCF method have been found. For the most perspective configurations the disintegration mechanisms have also been explored.
