Putting The Squeeze On Nitrogen For High Energy Materials

Researchers from the Carnegie Institution’s Geophysical Laboratory report changes in the melting temperature of solid nitrogen at pressures up to 120 gigapascals and temperatures reaching 2,500° Kelvin. These results, plus observed changes in the structure of solid nitrogen at high pressures, could lead to new high energy nitrogen- or hydrogen-based fuels in the future. Hypothesized nitrogen polymers could form materials with higher energy content than any known non-nuclear material.
