Molecular Dynamics Simulations of Weak Detonations [PDF]

, 2011
Detonation of a three-dimensional reactive non-isotropic molecular crystal is modeled using molecular dynamics simulations. The detonation process is initiated by an impulse, followed by the creation of a stable fast reactive shock wave.

Effects of Dipentaerythritol and Cellulose as Additives on the Morphology of Pentaerythritol Crystals

Crystals
The crystal habit of pentaerythritol (PE) crystals is usually rod-shaped, which may lead to low bulk density and bad flowability compared with low aspect ratio crystals.

Synthesis of 2,4,8,10-tetroxaspiro5,5undecane [PDF]

, 1985
Pentaerythritol is converted to its diformal, 2,4,8,10-tetroxaspirol5.5undecane, by heating it to a temperature within the range of about 110 to 150 C, for a period of up to 10 minutes, in the presence of a slight excess of paraformaldehyde and of a ...

Growth and dislocation studies of β-HMX [PDF]

, 2014
Background: The defect structure of organic materials is important as it plays a major role in their crystal growth properties. It also can play a subcritical role in “hot-spot” detonation processes of energetics and one such energetic is ...
