Dynamic and Energetic Materials Division
The Dynamic and Energetic Materials (DE) Division's major experimental activity comprises the synthetic and experimental chemistry of high explosives (HE). From high-nitrogen HEs that primarily produce nitrogen gas on detonation, to lead-free primaries, to nanoaluminum-containing HEs with improved detonation properties, new synthetic protocols are an ongoing area of research for a wide range of materials.
Shock physics is another major DE experimental domain. From laser-shocked materials, to gas gun experiments with HEs, to pulsed-power compression of metals, this arena seeks to reveal early steps in the chemistry and physics of explosives detonation-propagation and to derive equations of state for weapons-related materials.
A parallel and complementary computational approach to detonation-propagation known as the detonation shock dynamics model embeds essential detonation-structure information within a single mathematical function. Related research covers HE crystal growth and a variety of complex polymers and foams, many with critical applications in Department of Energy and Department of Defense weapon systems and the space program.
