Abstract

Multi‐protection is a principle in security management, and the use of anti‐explosion and fireproof agents is a crucial part of it. In this paper, the properties of nano‐oxide particles in the field of anti‐explosion and fireproof were analyzed. The sedimentation velocity of nanometer particles was calculated. CH~4~ was taken as an example, and its combustion mechanism of the initial stages was concluded. The effects of 15 oxides on molecular energies of the reaction system were calculated with program Hyperchem 6, and the possible contact manner between radicals and oxides was got. It was concluded that oxides, such as ZrO~2~, could combine with radicals, and thus prevent the combustion reaction. It was found that the nano‐ZrO~2~ eruptively generated aerosol is superior to other counterparts in serving as the anti‐explosion and fireproof agent, and therefore, will play an increasingly important role in the security management.

## Abstract To develop new highly energetic materials, we have considered the design of molecules with high nitrogen content. Possible candidates include 1,3,5‐triazine derivatives. In this work, we studied potential synthetic routes for melamine using the MP2/6‐31+G(d,p)//B3LYP/6‐31G(d) level of t
