I don't think the world needs easier ways to cast high explosives into precise shapes, but the scientists at Los Alamos just announced precisely that: an easy to use, low melting point high explosive that can easily cast into precise shapes.
ScienceDaily (Oct. 14, 2008) — Since the discovery of nitroglycerin in 1846, the nitrate ester group of compounds has been known for its explosive properties. A whole series of other nitrate esters have been subsequently put to use as explosives and fuels.
A research team led by David E. Chavez at Los Alamos National Laboratory (USA) has now developed a novel tetranitrate ester. The compound has a particularly interesting characteristic profile: it is solid at room temperature, is a highly powerful explosive, and can be melt-cast into the desired shape.
