Heidelberg 2011 Abstract: To further test whether polynitriprismanes are capable of being potential high energy density materials (HEDMs), extensive theoretical calculations were carried out... of PNNPs. The computed BDE for cleavage of C-C bond (88.5 kJ/mol) further demonstrates that only the hexa-nitrotriprismane can be considered to be the target of HEDMs. Key words: high energy density......
and swell after sintering. The forming ability of HVC lies on impact energy and powder filling amount simultaneously. Therefore, mass energy density can characterize the green density achieved at different powder filling amount and impact energy. For pure Ti powder, the green relative density is 96.0% when the mass energy density is 118 J/g. Key words: Ti powder; high velocity compaction......

of more than 300 ℃[2]. The slow kinetics may be explained by the high energy barrier to be overcome[3] to dissociate the H2 molecule due to the tendency of Mg to repel the s electron of H because... chemisorption. 2) The energy barrier for hydrogen dissociation is high on the pure Mg surface (1.08 eV) and it is small (0.101 eV) when Fe is used as dopant due to the strong interaction between......
, the energy consumption, strain rate and dynamic strength were analyzed. And the fragmentation behaviors of specimens were investigated. The experimental results show that the energy consumption density of rock increases linearly with the total incident energy. The energy consumption density is of an exponent relationship with the average size of rock fragments. The higher the energy consumption density......
